I’m calling it right now, if you keep these videos up then people in Hoggit sub are going to use “Gaffer” as a household name like RedKite when it comes to recommending DCS videos. Great as always, I always learn something new.
Why are they called hoggit. Sounds like hobbit
You forgot Ralfidude..his videos are amazing too.
@@dangerously72 Only gave one example, but Ralfi is great as well! Wouldn't have the A10 as my main without him :D
Referencing reddit LMAO
That was such an essential concept that needs to be shared about fly-by-wire systems being design to seek 1G!!! I have been flying in DCS since it came out (still not that good at it all), and somehow missed that along the way. I havent done multi and really only fly solo, probably why i am so far behind. That was one of those head explode moments where I am like, "ahhhhh, now I get it!"
Thank you for sharing mate! Now I can quit fighting my jet and start flying it.
It is any first time hearing this seek 1g program seems better than what i have been doing
Little things can be the most amazing things. Anything that gives you more of a connection to your ride is special.
Great explanation. Little addition to the trim. One very useful pitch trim is on strafe runs. 0.5G for strafes works like a charm. After that trim back to 1.0G. Give it a try ;)
Thanks for that critical piece of information. I started flying the su-27 which you need to constantly trim out, as there is no advanced FLCS. So I was constantly trying to trim the Viper manually and asking myself why I'm so bad at keeping straight and level flight
Thanks for the research and the demo. I appreciated the aerodynamic video with CAS/TAS explained from the air molecule’s perspective
Thanks! For anyone interested, the TAS/CAS and fuel flow explanation was in my "Speeds to fly" video. ua-cam.com/video/bZnoWXe_joE/v-deo.html
This is such an in depth video. Thanks, I feel like I understand trim way better now.
Wow, you've explained this so well. This is really good stuff, thank you
Well if I can explain it to a clueless clown, I can explain it to anyone. Thank you!
it all clicked in my head the moment you said you're commanding Gs
You're a brilliant teacher mate, simple explanations with visual demonstrations immediately, thank you! I look forward to ALL of the next content hopefully to come soon.
Another awesome video!
This is the best explanation of these topics I’ve ever seen. Thank you!
Great videos. I've fine tuned my F16 skills because of your videos. Thanks.
Excellent 👍🏻 I have learned a lot 😊 Thank you very much for this video about the FBW and the TRIM of the F-16C 😃
This is gold. Thank you for explaining such basic stuff which I obviously missed and wondering why this f... Plane does not hold pitch in a turn. Now it all makes sense!
Brilliant work!
Good job on these F-16 tutorials you are spinning out. I see the relevance of trimming also during turns on final when doing overhead break. Constantly fighting the nose pitching down state with massive throttle adjustment and this tends to make me get the runway alignment wrong. I now see where a 2 click trim will help smooth out things at this stage.
Huge fan of you videos. Cheers.
That seeking 1g is incredible, automatic level flying angle where ever you leave the stick no nose drop downs I'm trying to program this into a fighter jet
Very nice, thanks! Loved the non-landing demonstrations. It explains why I couldn't practice some landing concepts with my gear up :) So to be sure, when gear is down, pitch commands AoA and thus you go into the classic mode of pitch for speed (as a higher commanded AoA necessarily means lower speed all things equal) and throttle for altitude (moving the FPM). So then despite FBW it behaves like a Cessna :)
Other thing is on landing viper pilots don't pitch (AoA) trim, right? Contrary to say an A10c that you trim for AoA on approach. That was just a demonstration here.
And again. I fly the F-16 since release and still learn some new stuff. I was ever afraid to trim this aircraft. But today i understand it and will use it as a tool. Thx so much.
great channel! outstanding!
Holy hell this is amazing. I always wondered what trim did in a FBW plane, and in particular the viper. My only constructive feedback is that it would have been somewhat nice to have the controls indicator up for the demonstrations. Otherwise though, this completely changes how I think about flight in the viper.
Ha I had the exact same thought after I finished this. Will keep in mind for future videos. Thanks for the suggestion!
I'm also planning a part 2 to this video and will definitely include the controls indicator.
@@FLYGaffer Ha, I noticed it on the recent videos discussing the FM changes. To be honest though you did such a good job explaining what you were doing in this one that I didn't miss it too much, but having it for future similar videos will still be helpful to see exactly how much stick and trim movement produces a result.
I am new to DCS and I got the F-16 as a first fighter jet even thought I really wanted the F-14... I figure this one is the best first jet. Thanks for these tutorials they are very helpful.
You're the man, this is something which took me a long time to figure out. I wish I had this video back in the day hahh
Don’t know how I didn’t get recommended this video, pretty amazing
Nice tutorial, thank you!
Very informative, thank you for sharing!
Bro learning the 16 and i was wondering (besides it being a different plane) that the 14 and 16 felt so different. Cheers!
Great content, well delivered, thanks a lot.
Appreciate it!
Awesome info! 😀
Amazing how many videos you've been uploading the past few days.
Matt Wagner has four videos flagged as a 'favourite' on his almost 15 year old UA-cam account. This is one of those four videos.
very informative!
This is a great video :)
Good vid, man.
Fantastic!
nice tutorial about fbw system on f16
BEAUUUUUUTIFUL Landing
Subscribed... Thanks!
good job thx :)
How do you handle roll trim when carrying a TGP or HTS or other asymmetric loadout? It's hard to trim for roll caused by the TGP. I use yaw trim to center the ball on the ADI. It's hard to get it just right and it usually takes some fine tuning. Is there a better way?
Strangely flying the F16 made a lot more sense to me after learning to fly an Airbus A320
…ironically the logic of the F-16 is almost identical to normal law high aoa protection of the A320
Just curious, why do you want to be at the top of the AOA bracket and not in the middle of it?
Per a block 50/52 manual you can find with the google search terms "F-16 manual" a preferred landing technique in the F-16 is to approach on final at the top of the AOA bracket at 11 degrees, and flare to 13 degrees (middle of the bracket) to touchdown. See section 6-4
This is unlike the hornet where you don’t flare to land, you just approach at the landing AOA and let it’s massive landing carrier gear soak up the landing. Thanks for watching!
@@FLYGaffer Your landing is very close to mine. I'd always figured the indexer is trying to destroy the roadwheels and dampers so I didn't pay it any mind. Only thing I look at on approach is airspeed, lol. Cross the threshold stable 160 - 180 without pitch rate and without a lot of sink rate and you are okay.
@@FLYGaffer Found the passage in the manual, it mentions an 11 or 13 degree approach but doesn't indicate a reason for choosing either. Is there one ? Wind maybe ?
@@TheSkipjack95 From that document Re: 11 degree AOA
"This technique allows better pitch control, better over-the-nose visibility, and a more stable HUD presentation. In gusty wind conditions, the aircraft wallows less, and during the flare, the sink rate is easier to control."
Sounds good to me. Also found some other documentation from 1996 indicating that was preferred. It's been working well for me!
I must’ve missed the part in the manual about adding pitch trim to reach 11AOA on approach. Flying in Falcon BMS I think that’s achievable without trimming… can’t recall for sure
"In takeoff and landing gains, zero pitch trim commands zero pitch rate until 10 degrees AOA. A slight amount of noseup trim is required to zero stick forces during an 11-13 degree AOA approach."
Thanks for watching!
Probably going to depend on the state of the plane.
You definitely wanna roll-trim after firing munitions. F-16's quite light and the munitions have a very big aerodynamic impact. Granted I don't know if DCS does this correctly enough for it to matter. Drop 2000lb'ers one at a time and you'll see what I mean.
It absolutely does, even with something like a single sidewinder
Cool videos with a lot of explanations. Enjoying it.
Just a reminder though, you don't trim F16 for landing. Using throttle for AoA adjustment is the correct way. That's from a real F16 pilot.
Thanks for the videos.
Appreciate it!
A note straight from the Block 50/52 manual reads "In takeoff and landing gains, zero pitch trim commands zero pitch rate until 10 degrees AOA. A slight amount of noseup trim is required to zero stick forces during an 11-13 degree AOA approach."
I've found this to be accurate in-game. Unless you trim, a slight amount of stick pressure is required to maintain 11 AOA. One or two clicks nose-up trim and it will maintain it hands-off.
@@FLYGaffer that's completely correct what's written on the manual, that's also used as a second technique but maybe for %10 of the landings, depending on weight or to avoid tailstrike in particular circumstances. though with proper adjustments to throttle it is quite easy to hold 13 degrees AoA as the Vipers stick is force-sensing. In DCS, trimming for AoA works very well as you said.
Keep up the good work!
I have been flying the Viper since the early days of Falcon 4 and trimming for landing was never a thing. I kind of cringed when even Wags mentioned doing a 2 click trimming in his Landing tutorial for the viper.
Now it is pretty obvious how much smooth and easy it is going by the book and Gaffe video just makes the reasons for trimming understandable. I have been doing landing all these years with thottle/flightstick setting to keep AOA but I sure will be using the trimming method onward.
@@ernestwinslow7316 hi! Wags is never using trim in his landings, i asked him personally. Trimming is just another technique which is not mostly used. F16 is to be trimmed only when there's damage on aircraft.
@@silvera- Thanks Fiko for the additional information and correction. I may have quoted Mr Wag wrongly in my earlier reference. I can vaguely remember him mentioning trim in one of viper's videos but I appear to be incorrect after watching his landing lesson for the Viper. It is great have more than one technique in controlling this iconic jet.
Is the bore sight cross basically the same as FA 18 waterline?
pretty much the same thing
Nice explanation, but there are many situations where trimming the aircraft would be required other than holding pitch in a turn lol.
i only use trim for air refuelling and stabilizing uneven loadouts
This is just Angular rate limiting fbw it seems.
From an Air Force Aircraft Mechanic standpoint, that’s not what Fly By Wire means. It literally means the flight controls are electronically controlled, where as traditional flight controls get their input via cables.
How does the hornet's fly by wire differs from the f16?
