For everyone asking about the last pin not being pulled, the pin is the Chaff/Flare pin. This pin gets pulled at the EOR (end of runway) check/inspection by ammunition when the aircraft is loaded. I'm crew-chief on heavy aircraft and we also have pins to pull before the aircraft taxis off the spot, as we do not do EOR checks or in some cases not always will pull them in the air being the box is usually located in the cargo area as some frequencies can set them off when parked.
@@thepioneer6178 because chaff and coutermeasures are dangerous and very inflammable, and in case of an accident / unforseen activation, you want it to happen when the airplane is isolated when ready to take off. before you pull the plug, nothing can get activated by mistake, it's the reason they even exist.
You should rename this video to "F-16 Launch Procedure." Pulling the EPU pin is only one step in the whole thing. This video would be a great learning tool for future F-16 crew chiefs.
@@pukinator1 it depends on the crew chief on how they do it and the speed they do it. There aren't that many videos on how to launch so this video is something to go off of.
@@88sideburns22 i understand everyone has their own ways but i have been a crewchief on the f16 and used to walk around once, also pulled the epu as one of the last things to avoid possible hydrazine contact
Good to see that procedures haven't changed since I crewed the F-16 back in the late 80's. I still remember all of those checks. I love the smell of jet fuel in the morning. ;-)
I have a coffee cup that says that. As a retired development engineer, for the engines, I got to the early mornings by staying up all night. And no, we weren't paid for our overtime!
I was taught these steps in a completely different order. Wouldn’t start shutting any doors until after EPU run up. Interesting to see this. Nice video !
Former Crew Chief here, I'd always kiss my fingers and then touch the wing after a launch, asking my Jet to bring the pilot and herself back safely. Dunno about the gimbal check they other guy was taking about
I was lucky enough to be an Electro-Environmental technician on these jets with the 132 FW before the AF decided to move our jets to AC and DC back in 2013. This A/C (407) and the one sitting next to it (303) were both from our unit, and I know that I turned wrenches on these airframes both at home and abroad. I retired last year, but I still very much enjoyed seeing some of my old tail numbers in action! I know I was far from the only one who was devastated when our jets left... And yes, you should pull the comm cord by the plug, not the cable. I was one of the poor souls who got to repair those cords by the bushel basketful!
They do have to have some way to hard-safe things if they need to divert due to damage, malfunction or fuel exhastion. It's better than just tossing a wad of flagged lock pins into the cockpit Every pilot gets to learn how to do the stuff their crew chief does for them in case they're unavailable for some reason, and having the pins in the same place every time prevents losing them or forgetting them.
Great idea. A, every plane carries its own set, much easier logistically, and you don't have to track, store them, have extras in case of unexpected events or emergency. It stays in the hole, or in the integrated storages, never leaves the plane. This alone would arguably offset the minor fuel efficiency & performance loss of their mass in flight. B, in emergency settings- war, transfer, scramble, or landing- it has its safe-ing pins, even in nonstandard locales. For a military craft, invaluable. (See first reply) C, if it shows up anywhere missing any of them, thats an integrated safety spot check, giving a rapid self-check capacity to relevant safety issues. Again, invaluable. Just by carrying less weight than a packed lunch.
Every jet has a place. Example: A-10 ground pins ( EXCEPT WEAPONS RELEASE/ ARM ) went inside the FUEL MANAGEMENT/SPR ACCESS DOOR which is on the left wing at the Lead edge of the BUMP on the fairing for the left main landing gear
@@ihavenoidea9543 Avionics wouldn't be stuck fixing that. It would be the support section. OP is correct that is a rather crap way to disconnect the comm cord. It will break doing that prematurely.

Our son, an F-16 Crew Chief had died in another accident a couple months before this happened to his best friend... An F-16 pilot accidentally dumped the hydrazine on a crewman on the ground, giving him chemically induced leukemia. It took 18 months, more or less for him to die. We got to say goodby to Michael the day before he left us at the Seattle VA hospital.
@@michaellim4165 yeah, hydrazine is really nasty stuff, my knowledge of it from the space industry is that people try to avoid using it in designs for the first place but sometimes it's just needed and that creates a ton of extra precautions and procedures because the crew working around hydrazine related chems is at risk for something like what happened to the crewmen
@@maverick9708 We were told that they taught crew chiefs that one breath of the fumes takes 10 years off a person's life. I heard that later blocks of F16s had a different system w/o the hydrazine...after watching this, maybe not. I think there is a YT safety video about a hydrazine spill during a transfer from a truck to a storage tank where some people died.
YES, it's the Crew Chief's job to remove that safety pin just prior to the pilot to taxing out of the chocks! I've worked on the Lawn Darts for over 8 years and way back when I was just a skitter wing at Nellis AFB, NV, was sent to Luke AFB, AZ to recover a broken Lawn Dart from our wing (Spark Chaser and had to replace the IDG and do a Monopropellant Ops Check, AC & DC Distribution Check because the Main Generator Disconnected while in flight) and while we where awaiting our planes to clear EOR there was a flight of Lawn Darts at EOR getting cleared for their training mission that night, when my trainer, the planes DCC and ACC (Dedicated Crew Chief & Assistant Dedicated Crew Chief) and I was in our step van when we seen a 3 Level Weapons Trooper get sucked into the main intake of an F-16, just after the CC pulled the EPU Safety Pin and the pilot went to 85% Throttle then turned on the EPU in Bleed Air Mode, needless to say the young trooper was killed when his body hit the First Stage Compressor Blades. After the investigation the AF came down with a change to the pre-flight ops cks of the EPU, the Safety Pins are pulled at the parking spot, then the Bleed Air Ops cks of the EPU is then done at this time then the plane is released to taxi to EOR. Also the USAF recalled and banned all Parka Hood attachments to all F-16 maintainers field jackets because the investigation found that when the F-16's engine throttle went to 85% the amount of air drawn into the aircraft's main intake within 4 feet aft of the intake causes the Parka Hood to blossom like a small parachute and then able to be pulled with everything attached to the hood into the intake. SO THIS TITLE IS NOTHING BUT CLICK BAIT, Nothing seriously to be scared about pulling a safety pin to the F-16's EPU Ground Safety Switch just prior to the planes taxing, or even a ground maintenance run (IT'S STANDARD PROCEDURE)
I was at cannon AFB from 2001-05 when they had 5 squadrons of F16s. Didn't work on them at all - I worked in airfield management. Spent a lot of time on the airfield though watching. I was obsessed with the F16 (and aviation in general) since I was a kid and played Falcon 3.0 on the computer 😂
@@phoenixskeptic7698 nice! I actually found pieces on the airfield from an f111 that crashed in the 90s. Covis sucked but looking back, I kind of miss it😂
Always a favorite. Love the close footage. It really is just an engine with wings and a seat lol. Also like the panel latch procedure of doing the hand sweep to catch anything not latched.
By the way that's not the flcs panel, that's where there a delta p for the motor called the lipstick delta p. The pneumatic is underneath the lt strake next to the stab.
That's not a rope it's the communication line to the plane. It's how the crew chief and pilot stay together during the start-up. The engine generates so much noise you would never be able to talk without that connection.
He’s NOT looping the cable over the panel. The crew chief has the COMMUNICATION cord with the TALK BUTTON in his hand. He needs his hand to do the panels…
My son was an F16 crew chief. His best friend had a pilot dump the hydrazine on him out of an F16 at Misaua Japan in about '96. Diagnosis: Chemically Induced Lukemea. Took about 18 months of misery for his body to die. We got to say our goodbys at the Seattle VA hospital the day before he left. Hard to believe they still use that stuff. I thought later F16 Blocks had done away with it... We heard that one breath of hydrazine fumes will take 10 years off someone's life.
Him going behind the Aircraft while it was Running and there was Hot Exhaust Coming out the back, he is one brave, brave man, I would never in a million years do that XD
You would be surprised how many people got caught walking behind the jet and got blown down the ramp several hundred feet. He stands there while the flight control computer finishes it's checks and then the pilot does several checks such as nose up, down, roll left, right, then rudder left, right. The Crew Chief calls them out as the pilot does them for verification. SO that's the best spot to see them from. If you think it's hot, try doing it in the middle east in summertime. We would be drenched in sweat by the time the pilot taxied out.
@@TheOpacue Ready 5 is the designation for aircraft that are prepared for immediate take off in case of attack. In the film topgun they call it Alert5. The aircraft shown are being prepared for a standard mission.
@@trig ooh cool! Like "just check the absolute necessities" kind of thing? Is that like "ready in 5 steps", or ready in 5 minutes? Like, what does the 5 stand for? So interesting 😁
@@TheOpacue Its 5 minutes, they are armed and fueled with the pilots in their seats in an area at the end of the runway. I suspect that the planes still have a number of pins in place as they need to be spooled up and the weapons made ready. I am not an expert, that's just what I have picked up over time.
Being a crew chief is only fun the first few years. Then the aches, pains and hearing loss sets in. We do our best to make it fun but a lot of commanders don't approve of moral.
Nice to see the old flight control system self test. Do almost remember the steps ;-) One thing tho,- Don't stand there at JFS start and operation. when the JFS breaks up, thats where the pieces comes..... Telling from a friend !!
Super interesting! I had no idea that the f-16 has a hydrazine powered EPU. Was reading up on it and it is pretty interesting how it works. Does this mean the f-16 does not have any kind of apu and has to use the epu to start up?
It's basically for power demands in case of in air catastrophic engine failure from what I understand... then assuming you sagely land at the nearest appropriate runway It's a circus of emergency response/hazmat teams and the pilot staying sealed in his bubble until a sniffer gives the all clear or he's down to his minimum pure oxygen, I assume off of the pony bottle in the ejection seat or maybe in the parachute? Lots of precautions for a pretty low system design, but why risk anything with hydrazine 😵 I know there is atleast one good video on UA-cam including communications, where the APU was activated and saved the aircraft, that detail was also an important part of the information relayed to the tower, since it was an emergency landing at a civilian airport if I remember right so they didn't want people rushing up to the neat gray jet pouring out death gas lol
The jfs is for engine start only. Any power required for maintenance or ground tests gets supplied by a generator set called a dash 60. The epu provides emergency power etc in case of an engine failure in flight.
The U2 uses Hydrazine also. No room for an APU and extra weight. It’s used only for restarting the engine while in flight in case of flame out. Older turbojet engines could windmill the engine in flight to restart. With the newer turbofan engines they need assistance.
After a while I got somewhat bored and thought to myself ‘launch already’. But the close up of such cool and live machinery won me to keep watching with attention till the end. 👍🏼
@@ntal5859 The pilot completing his flight check list and waiting for taxi clearance from the tower. Also waiting for any other fighters to complete their startup checks so they all taxi together.
I think its being pulled on the pad here because of just how gigantic the tarmac is, still kinda weirds me out to see it not pulled at the EOR station.
Anyone interested in the development of hydrazine and other liquid rocket propellants should check out the book "Ignition: an informal history of the development of liquid rocket fuels" informative and pretty funny as well.
Could someone answer a question for me? I was Navy airdale, with VF-143 and we always had more than 1 person there outside a running jet, just in case. Even in the Army National Guard we had battle buddies. Does the air force not do this? Yes I see other people out on the flight line, but no one else there at that jet with him, and I know on an active flight line, at that distance, people would not easily be able to hear a call for help, let alone be right there immediately if something went wrong and this turned into one of those seconds matter life and death situations. Good on you guys and thank you for carrying on the torch for us.
Yea, If you notice there are a couple of vehicles around the jet watching. Inside are production supervisors/flightline expeditors. They all have radio communication with ground operations. The crew chief is also in communication with the pilot of the jet via the black ics cord. Once that's disconnected you'll notice he stays in view of the pilot during launch.
Whenever a truck is passing me in a truck stop, I have to reach out to touch the tail of their trailer just like this gentleman taps the wingtip missile.
Soneone help me out...liked the video. But kept noticing Orange pin flag in front of Starboard Tail. Other flags pulled except this one? See it around 9:06.
Also the safety pin box should have the places to insert each pin. No more or less than the number of pins. That way if there is a spot open or you got an extra it is time to figure out the mistake. Also it would secure the pins better.
>This was a nice video, a lot of corporation goes into a takeoff and the pre-flight checs. But I cant figure out why Hydrazine is used, there must be a specific reason for this. ?
Did he forget a safety pin on the right side just forward of the aileron i think its called? Or is that pin pulled just before flight? Im a navy vet and we pulled all safety pins before aircraft rolled from the flight line. Nevermind just read the comments below.
I guess everybody's MOI's can be different. I have seen striking differences in operations between Air Guard, Air Reserve and Regular Air Force in my days on active duty.
How many times can you walk under the EPU exhaust port after unpinning. 1500° heated EPU air will not feel good if the pilot were to hit the EPU switch by mistake. (Not likely) but it has happened and I’ve pulled many pilots out of these birds for runway as well as in flight emergencies. This make me miss the good old days!!
Seems like the pilot should be responsible for locked/unlocked items from the cockpit. Then maybe have a small light or other indicator showing in certain locations whether the status of the locked/unlocked items for the ground crew to visually check. Then the ground crews can just verify by sight and have less hands on and if something gets missed during a check the pilot would still be able to activate the items from the air if or when needed.
Okay where's this guy's B man the pull chocks. I guess they don't use a B man for that anymore. I remember at Hill AFB, UT we would the Specs guys or even Weapons as our B Man to pull chocks as the crew chief stood out front to marshall the aircraft out.
8:01 OMG you cannot pull cords like that from the cable boot or the wire, it has to be from the collar/sleeve of the plug or you're guaranteed a failure eventually... but awesome video
did Anybody notices that the Chief didnt pull the safety pin on the Right side of the plane, just front of the right Vertical Stabilizer? is it not a Safety pin or is it Something i dont know about? you can see it still there after he detached his Headset Cord at 8:18 edit:i notice many Japanese Comment mentioning Timestamp of the exact time that tag is Visible so i guess many did notice it
I was never really much of a fan of the F16 but I have grown an appreciation of the Viper over the recent years; quite a good looking aircraft. Whilst I know what Hydrazine is, I don't understand the relevance of it in relation to the pre-flight of this aircraft, or why it was highlighted. The Crew Chief pulls many pins, and checks many panels as usual. Still enjoyable being close to a grey jet tho.
But sadly it was time to shut down and refuel by the time pre-flight was complete 🤣 not a knock on the procedure, just the burn time without drop tanks
The hydrazine is the fuel for the Emergency Power Unit (EPU). If the F-16 loses its engine, because it's a fly-by-wire aircraft, it won't have electricity to run the Flight Control System (FLCS) from the engine anymore. The EPU burns hydrazine to generate electricity for the FLCS in the event of an engine failure so the jet can still be safely flown and glided either down to a landing or to a safe area to eject. The F-16 has about ten minutes worth of hydrazine on board, which is plenty to land/safely eject in most phases of flight. The downside is that burning hydrazine creates highly toxic fumes, which is why the leak indicator is so important, as well as showing the pilot that the EPU pin has been pulled.
Epu check is to check that the epu runs on bleed air mode then to check if the bleed air stops flowing. The pin is shown to the pilot so that when the epu is run up the crew chief is not there in case of accidental hydrazine activation.
@@slpkntmggt06 Thanks Austin for a nicely detailed reply. I know that the Blackbird used H7 to restart their engines when they flamed out, and they had a counter to keep track but didn't realise the significance of it in relation to the Viper. Cheers mate.
@@slpkntmggt06 Additionally, hydrazine is catalyticaly activated within the EPU. This allows the EPU to operate without need of electricity from any external power supply (e.g., batt and/or gen). If the EPU was run say like the plane's JFS using fuel, the EPU would then need an ignition system to run. So, hydrazine also makes the EPU less bulky and complex too.

I am impressed by the simple check system of looping the rope over panels to verify a rewalk and the safety pin box. Sometimes its the little things.
That's not a rope it's the communication line to the plane. It's how the crew chief and pilot stay together during the start-up. The engine generates so much noise you would never be able to talk without that connection.
All useful things are based on very simple mechanics. Overly complicated mechanisms are almost never combat effective.

Me-163 does not use hydrazine
@@ionator2000ist ; Laughable, look up C-Stoff. Hydrazine hydrate 30%
My son was an F16 crew chief. His best friend had a pilot dump the hydrazine on him out of an F16 at Misaua Japan in about '96. Diagnosis: Chemically Induced Lukemea. Took about 18 months of misery for his body to die. We got to say our goodbys at the Seattle VA hospital the day before he left. Hard to believe they still use that stuff. I thought later F16 Blocks had done away with it... We heard that one breath of hydrazine fumes will take 10 years off someone's life.
Impressive, quite the process to take off.

Him going behind the Aircraft while it was Running and there was Hot Exhaust Coming out the back, he is one brave, brave man, I would never in a million years do that XD
You would be surprised how many people got caught walking behind the jet and got blown down the ramp several hundred feet.
He stands there while the flight control computer finishes it's checks and then the pilot does several checks such as nose up, down, roll left, right, then rudder left, right. The Crew Chief calls them out as the pilot does them for verification. SO that's the best spot to see them from.
If you think it's hot, try doing it in the middle east in summertime. We would be drenched in sweat by the time the pilot taxied out.

They had to stop recording so they could refuel the planes since the preflight takes so long
I was taught never pull on cord to disconnect. Pull on plug.
I never knew the pins were stored on the planes themself. i always assumed the crew chief keeps them. actually make kinda sense.
I agree. But yes it makes sense that if the jet landed somewhere else it brings its pins.

Would be interesting to see a "Ready 5" precheck for comparison...if there is one.
What is that, and what is the difference between that and this?
@@TheOpacue Ready 5 is the designation for aircraft that are prepared for immediate take off in case of attack. In the film topgun they call it Alert5. The aircraft shown are being prepared for a standard mission.
@@trig ooh cool! Like "just check the absolute necessities" kind of thing? Is that like "ready in 5 steps", or ready in 5 minutes? Like, what does the 5 stand for? So interesting 😁
@@TheOpacue Its 5 minutes, they are armed and fueled with the pilots in their seats in an area at the end of the runway. I suspect that the planes still have a number of pins in place as they need to be spooled up and the weapons made ready. I am not an expert, that's just what I have picked up over time.
@@trig that is so cool though! What is spooled up?
At 02:53 just after the crew chief has removed the EPU safety pin, you hear the engine spooling up. That's the pilot testing the EPU
Nothing could be cooler than being a fighter pilot, but it must feel so badass to be a crew chief too.
For sure, until your commander sends you to die in a third world country we're invading for oil by some random SAM.
Pretty cool to be a Russian or Chinese spy, sitting in a bunker taking notes from this video also! They don’t even have to work for it anymore!
Being a crew chief is only fun the first few years. Then the aches, pains and hearing loss sets in. We do our best to make it fun but a lot of commanders don't approve of moral.
@@rasmusericsson8447 Lol the F16 is nearly 50 years old. None of this is a secret.
@@Studio23Media it’s a joke man 😉
Nice to see the old flight control system self test. Do almost remember the steps ;-) One thing tho,- Don't stand there at JFS start and operation. when the JFS breaks up, thats where the pieces comes..... Telling from a friend !!
Never once saw a JFS fall apart like that and I worked the aircraft for 20 years. We always stood by the fire bottle.
@@Stubbies2003 Saw two desintegrate in 25 years. Not much, but the compressor pieces from the JFS (5x10mm) was nailed in wood work 30 feet away.

ララライララライ じゃないですか？
Super interesting! I had no idea that the f-16 has a hydrazine powered EPU. Was reading up on it and it is pretty interesting how it works. Does this mean the f-16 does not have any kind of apu and has to use the epu to start up?
No it has a jfs
It's basically for power demands in case of in air catastrophic engine failure from what I understand... then assuming you sagely land at the nearest appropriate runway It's a circus of emergency response/hazmat teams and the pilot staying sealed in his bubble until a sniffer gives the all clear or he's down to his minimum pure oxygen, I assume off of the pony bottle in the ejection seat or maybe in the parachute? Lots of precautions for a pretty low system design, but why risk anything with hydrazine 😵 I know there is atleast one good video on UA-cam including communications, where the APU was activated and saved the aircraft, that detail was also an important part of the information relayed to the tower, since it was an emergency landing at a civilian airport if I remember right so they didn't want people rushing up to the neat gray jet pouring out death gas lol
The jfs is for engine start only. Any power required for maintenance or ground tests gets supplied by a generator set called a dash 60.
The epu provides emergency power etc in case of an engine failure in flight.
@@berryreading4809 Hydrazine is very water soluble. So they probably hose down the aircraft.
The U2 uses Hydrazine also. No room for an APU and extra weight. It’s used only for restarting the engine while in flight in case of flame out. Older turbojet engines could windmill the engine in flight to restart. With the newer turbofan engines they need assistance.
早い、丁寧、プロとして当たり前の仕事って感じ。

I think its being pulled on the pad here because of just how gigantic the tarmac is, still kinda weirds me out to see it not pulled at the EOR station.
Anyone interested in the development of hydrazine and other liquid rocket propellants should check out the book "Ignition: an informal history of the development of liquid rocket fuels" informative and pretty funny as well.
Been a decade or more since I read that. I concur it is a pretty good read.

Could someone answer a question for me?
I was Navy airdale, with VF-143 and we always had more than 1 person there outside a running jet, just in case. Even in the Army National Guard we had battle buddies. Does the air force not do this? Yes I see other people out on the flight line, but no one else there at that jet with him, and I know on an active flight line, at that distance, people would not easily be able to hear a call for help, let alone be right there immediately if something went wrong and this turned into one of those seconds matter life and death situations.
Good on you guys and thank you for carrying on the torch for us.
Yea,
If you notice there are a couple of vehicles around the jet watching. Inside are production supervisors/flightline expeditors. They all have radio communication with ground operations. The crew chief is also in communication with the pilot of the jet via the black ics cord. Once that's disconnected you'll notice he stays in view of the pilot during launch.
I like it, this is a very good vid!

Just curious, is there different protocol during an alert or scramble?
I imagine different aircraft would be required for a scramble.
8:56 - So why does that tagged safety pin remain in? Or did I miss when he removed it?
It probably gets pulled by the weapon guys at the arming point near the runway. That safety pin prevents dispensing of chaff and flares
Yup gets pulled at End Of Runway(EOR) as it's the safety pin for the chaff/flare which is an Aircraft Armament job
Why did he leave the last safety pin in, at the right horizontal stabilizer? Does anyone know?
Chaff/Flare safety pin. Doesn’t get pulled until the A/C arrives at EOR (End Of Runway). Weapons personnel will pull the pin there.
Yes we all know. 😁
@@Juno58 I mean, he was asking a question? Obviously he didn’t know
Soneone help me out...liked the video. But kept noticing Orange pin flag in front of Starboard Tail. Other flags pulled except this one? See it around 9:06.
Also the safety pin box should have the places to insert each pin. No more or less than the number of pins. That way if there is a spot open or you got an extra it is time to figure out the mistake. Also it would secure the pins better.
wow! so different from the way we launch our F16 C/D/D+!
@USA Military Channel You forgot to post your distribution statement and authorization letter number.
Glad you're on our side - Go Tigers - ;O)
>This was a nice video, a lot of corporation goes into a takeoff and the pre-flight checs.
But I cant figure out why Hydrazine is used, there must be a specific reason for this. ?
I wonder... The little dangling thing on rear of the aircraft... Just dangling there on the rudder, what is that? 5:47
Whatabout the last red flag at the right side of the tail in front of the stab?? Did he forget that or what?
Chaff/Flare pin that is removed at EOR (end of runway)
8:15 that’s not how you unplug connectors and that’s also not how you coil audio cable.
Did he forget a safety pin on the right side just forward of the aileron i think its called? Or is that pin pulled just before flight? Im a navy vet and we pulled all safety pins before aircraft rolled from the flight line. Nevermind just read the comments below.
I guess everybody's MOI's can be different. I have seen striking differences in operations between Air Guard, Air Reserve and Regular Air Force in my days on active duty.
こんな所まで見せてくれるこのチャンネル好きすぎる(≧∇≦)発進からの敬礼のハンドサインみたいなのかっこいい！
The EPU pin used to be pulled on EOR, otherwise verbatim how I used to do it in the 90's.
The epu pin was only pulled at arm end of EOR only after a Hot pit refuel, otherwise it was pulled in chocks during launch.
Saw the same as Sean. centerline and EPU was always pulled and stowed prior to taxi.
@@seankeane6215 that is not true in modern times. epu pin will be stowed even after hot pitting.
How many times can you walk under the EPU exhaust port after unpinning. 1500° heated EPU air will not feel good if the pilot were to hit the EPU switch by mistake. (Not likely) but it has happened and I’ve pulled many pilots out of these birds for runway as well as in flight emergencies. This make me miss the good old days!!
Seems like the pilot should be responsible for locked/unlocked items from the cockpit. Then maybe have a small light or other indicator showing in certain locations whether the status of the locked/unlocked items for the ground crew to visually check.
Then the ground crews can just verify by sight and have less hands on and if something gets missed during a check the pilot would still be able to activate the items from the air if or when needed.
Why are all the panels opened? To see for fuel leak in preflight ?
Okay where's this guy's B man the pull chocks. I guess they don't use a B man for that anymore. I remember at Hill AFB, UT we would the Specs guys or even Weapons as our B Man to pull chocks as the crew chief stood out front to marshall the aircraft out.

Are there lights to tell the pilot all the little hatches are open or closed?
FLCS panel and IFF panel 🤣 🤣. But they got most of them right so I'll give them that
Asymmetric missile loadout? How many pounds fuel burned in that 12 minutes?
did Anybody notices that the Chief didnt pull the safety pin on the Right side of the plane, just front of the right Vertical Stabilizer? is it not a Safety pin or is it Something i dont know about? you can see it still there after he detached his Headset Cord at 8:18
edit:i notice many Japanese Comment mentioning Timestamp of the exact time that tag is Visible so i guess many did notice it
Its the safety pin for the flare box, probably removed by someone at the start of the runway
Yeah It's a Chaff/Flare Safety Pin which is remove along with all the Weapons safety pins during End-of-Runway Inspection.
@@pukinator1 thanks for the info :) so i guess there is ground crew at the end of runway that will pull it.
@@rifqitaqiuddin Only if there is live flares in the modules. Otherwise the crewchief will pull them

I was never really much of a fan of the F16 but I have grown an appreciation of the Viper over the recent years; quite a good looking aircraft. Whilst I know what Hydrazine is, I don't understand the relevance of it in relation to the pre-flight of this aircraft, or why it was highlighted. The Crew Chief pulls many pins, and checks many panels as usual. Still enjoyable being close to a grey jet tho.
But sadly it was time to shut down and refuel by the time pre-flight was complete 🤣 not a knock on the procedure, just the burn time without drop tanks
The hydrazine is the fuel for the Emergency Power Unit (EPU). If the F-16 loses its engine, because it's a fly-by-wire aircraft, it won't have electricity to run the Flight Control System (FLCS) from the engine anymore. The EPU burns hydrazine to generate electricity for the FLCS in the event of an engine failure so the jet can still be safely flown and glided either down to a landing or to a safe area to eject. The F-16 has about ten minutes worth of hydrazine on board, which is plenty to land/safely eject in most phases of flight. The downside is that burning hydrazine creates highly toxic fumes, which is why the leak indicator is so important, as well as showing the pilot that the EPU pin has been pulled.
Epu check is to check that the epu runs on bleed air mode then to check if the bleed air stops flowing. The pin is shown to the pilot so that when the epu is run up the crew chief is not there in case of accidental hydrazine activation.
@@slpkntmggt06 Thanks Austin for a nicely detailed reply. I know that the Blackbird used H7 to restart their engines when they flamed out, and they had a counter to keep track but didn't realise the significance of it in relation to the Viper. Cheers mate.
@@slpkntmggt06
Additionally, hydrazine is catalyticaly activated within the EPU. This allows the EPU to operate without need of electricity from any external power supply (e.g., batt and/or gen). If the EPU was run say like the plane's JFS using fuel, the EPU would then need an ignition system to run. So, hydrazine also makes the EPU less bulky and complex too.
That's Dave's shadow! I'd recognize it anywhere.
