Those ground air starters can start both engines at the same time on a 737. Years ago I was flying on a 737 where they started off the ground cart and they started both engines at the same time, a lot quicker than the traditional start off the APU. That airport also didn't use jetways so there was no pushback the aircraft was able to pull away from the ramp without a pushback.
The hardest engine I helped try to start with the start cart was the first gen RB-211 on a L-1011. It took forever, needed a lot of air and our buffer cart was tired. But after a long while it finally did start…
Concorde had to do this every time, and on each side.... since it didn't have an APU, and there was no cross-bleed between the left and right engine pairs!
@@dennisvijverbergbrakesrele6098 yep. For both weight and aerodynamic reasons, Concorde's designers wanted to avoid having a separate horizontal stabilizer (like Boeing's design) for trim, or adding canards (like TU144) for stability; so they decided to use active fuel-transfer to both trim and stabilize the aircraft while in flight. The weight of a APU would've comprised that design strategy, so they decided to leave it out, altogether. This was after evaluating APU designs from Turbomecha and Garrett, at the insistence of PanAm.
@@ChrisM-pu1hp Most APUs can start off the aircraft internal 28V batteries or sometimes need an external 28V d.c. source, but once the APU is running it can supply 200V a.c. for some systems and bleed-air to start the main engines and power the cabin-conditioning on the ground.
They're called "ground carts" --powered by diesel or gas turbines (not jet engines)--which supply compressed air for the engine's air turbine starter, plus electrical power. Note: once one engine is running, you can perform a "cross-bleed" start to start the other engine. You can see the airplane is being pushed back with only one engine running, so they'll do a cross-bleed start later on.
When we did air starts, the air cart did not supply electrical, just air pressure to start the engine . The ground power from the jetway had to be attached until the engine started, and the pilot would give clearance to disconnect ground power.
@@zekeonstormpeak4186 There's often a cable from the aircraft to the air producer that signals the start selection on the aircraft which triggers the producer to either open an air delivery valve or wind up to max for the start.
@@emmcee476 Hi in my case I went through about 7-10 days of training. When I was comfortable fueling, I told my boss I was ready to be on my own. As far as education goes just basic math skills are all you need and pay attention to your surroundings the flight line ( ramp ) can be a dangerous place. Hope that helps. Cheers from San Francisco
I think you'll find those vehicle are actually further away than they look and driving along marked roadways, so no real problem. If the aircraft is on a normal stand starting up for departure, then the engines will only run up to ground idle prior to pushback so fairly limited thrust in the efflux and the roadways would be positioned accordingly. If higher powered runs we're going to happen, the aircraft would normally be moved to a clearer running pan or area or the road behind temporarily closed. Ex line-swine and ramp-tramp😁
People are stupid in the Airport especially third party Ramp companies that hire anyone at my time working at YYZ I see planes get cut off over 20 times per day if you get caught you lose your AVOP I was wing walking the A380 last year and some Air Canada Supervisor almost ran me over when we were pushing I almost killed the guy 😂
Sorry, I’m a not a pro. Why didn‘t the use the APU to start the engines? Is this to safe fuel or for noise avoidance? Or was the APU inoperable? (Are you even allowed to fly with an inoperable APU???!)
Depending on aircraft ETOPS is not a requirement for ETOPS. With A350,B777 and B787 APU is not a requirement to fly ETOPS required flights. But it for example in this case limits the ETOPS flight to 180 minutes, if aircraft is a 270 minutes ETOPS aircraft it will need to be down graded.
It’s because it is foldable. Boeing made it that way for 1. They can go to smaller airports for taxing reasons and 2. It’s for shorter and longer flights
SAD to say that SAS don't operate this aircraft anymore. SE-RSC had since a month ago, been returned to lessor and is now being re-registered to China Airlines. SE-RSB has also left the SAS fleet, and has joined Malaysia Airlines to enter service as 9M-MAH .
An APU inop is no problem for normal flight, you are only restricted to 180 ETOPS with the A350. For restart of the engine the airspeed of the aircraft is used to restart, if I am not mistaken they will have to desend to an surtain flight lvl and fly a surtain airspeed, windmilling the engine will get the turbine above start rotation. And possibly restart with the bleed air of the other engine.
Im getting PTSD from my Ramp days back at YYZ when the plane we worked on with an INOP APU we would have to bring the Air Starter in and you can hear it across thr Ramp 😂😂😂😂 its louder than the engines themselves
I know it's probably not on the MEL, but is it a good idea to let a jetliner fly with APU INOP? Wonder how AWE 1549 would have turned out without the APU.
It is surely inconvenient if the APU is inop, but jetliners just fly fine without them. The A350 has two generators per engine. One engine can supply the airconditioning system with air without any problems. But it makes ground operations at time harder, especially when also ground equipment isn’t working either.
@@dennisvijverbergbrakesrele6098 They can fly without a working APU...until they can't. Dual flameouts do occur and when they do, you'll be very grateful if you have an APU. Yes, there's also the RAT but it can only power the most vital of systems and it causes a lot of drag in the process, which is a problem in "low and slow" situations.

Hello there, if APU is inoperative we use an external power plant for the electrical power. Air conditioning come form the yellow hoses attached to the gate. Then for start air and start unit the provides the pressure/flow to rotate the starter. The external power has two switches in the cockpit (there are two connection), the airconditioned air flows in the aircraft unregulated (no control or indication in the cockpit). For the start air the aircraft can sense that the pressure comes from an external source ( APU and engines are off) and configuraties the valve in the system so engines can be started. Hope it clarifies.
Airliners are such fantastic machines.
Innit
definitely mate
Just watching that lufthansa airliner in the background. That is one big aircraft!
That beautiful 747-8 in the background 😍😍
Indeed
It looks like it’s wrestling with the smaller 737 on pushback
As much as I like the A350, you just have to pay attention when that big bird began it's pushback.
Thanks for sharing! GREAT UP CLOSE of a 350 in action! Very cool!
Glad you enjoyed it
man i love air starters, they just make so much noise, the smaller the turbine, the louder they get
These RR engines looks stunning. The 350 looks great with this SAS livery though…. 👍✅
I agree!
Beautiful aircraft and beautiful British Rolls Royce engines

These engines need a bit more air to start then the B737.
How did you guys remove the cart from the plane? Isn't the danger area for the 737 quite close to the connection?
You need clearance for the air-start hose and the A/C hose.
What a beautiful machine
It sure is!

Very true, I too experienced the same
The engine than nearly bankrupted R-R. The UK government had to bail them out.
Yes correct, it has to crank the engine for a long time before the actual firing
@@manoahjohn2412 The fact the L1011 APU was weak even when new did not help.
Very nice
Thanks
I need to fly somewhere again. It's been a while. Such fun.
Most fastcinating was that last view on the engine, where you see how the air is divided. Never seen that before
I could tell by the blue color of the exhaust cowling this was a fairly new jet..as they get used more the blue fades to a Mat black!!!
Nice 747
I worked at Rolls-Royce for 23 years and inspected those very fan blades at our facility in Barnoldswick Uk

nice main external turbine air start # ❤️🇵🇰
Can a commercial jet like this start on its own using an APU or does it have to be connected to an outside (port) source?
It can start on its own using the apu
Probably one of main reasons to have a APU is engine start and electricity when engines are off. 😊
Most airliners start off the APU, because they start up during pushback in normal operatons
APUs are designed to do that and keep the airframe comfortable for passengers on the tarmac by supplying air to the A/C packs.
@@ChrisM-pu1hp Most APUs can start off the aircraft internal 28V batteries or sometimes need an external 28V d.c. source, but once the APU is running it can supply 200V a.c. for some systems and bleed-air to start the main engines and power the cabin-conditioning on the ground.

A jet engine IS a gas turbine and vice-versa.
Pretty good explanation, that’s how it works.

Check out the B747 in the background!
Why did they use the cart? APU not available?
Yes, APU inoperative
how do you know where and how to turn ? be careful! someone can always drive or walk across !
The airport has all paths lined out, just need to follow the correct one😬
Why was a huffer needed to start the engine?
APU inoperative
@@dennisvijverbergbrakesrele6098 OK. That makes sense.
Thank you movie🎬
Sorry, I’m a not a pro. Why didn‘t the use the APU to start the engines? Is this to safe fuel or for noise avoidance? Or was the APU inoperable? (Are you even allowed to fly with an inoperable APU???!)
APU was tagged inop.
APU had a fuel leak and couldn’t not be used, fuel valve was locked closed.
So wait a minute. An ETOPS aircraft is allowed to fly across the ocean without a working APU?
Depending on aircraft ETOPS is not a requirement for ETOPS. With A350,B777 and B787 APU is not a requirement to fly ETOPS required flights. But it for example in this case limits the ETOPS flight to 180 minutes, if aircraft is a 270 minutes ETOPS aircraft it will need to be down graded.
I think I flew on that LH 748 in the background out of either DXB or FRA about a year ago.
Our son probably made the wings for that plane at the Airbus factory in Broughton, north Wales.
1:02 for a moment I confused the plane with 777X as the wing tip seems pretty big and appears to be foldable.
It’s because it is foldable. Boeing made it that way for 1. They can go to smaller airports for taxing reasons and 2. It’s for shorter and longer flights
@@CapsIsCapin This is an Airbus A350 and not a Boeing 777X. Wing tip is fixed on the A350.

SAS also not servicing Miami with the A350 this coming winter season. To bad
Is having an APU inoperative a safety risk? Being able to restart the engines for example mid-flight?
An APU inop is no problem for normal flight, you are only restricted to 180 ETOPS with the A350. For restart of the engine the airspeed of the aircraft is used to restart, if I am not mistaken they will have to desend to an surtain flight lvl and fly a surtain airspeed, windmilling the engine will get the turbine above start rotation.

@@dennisvijverbergbrakesrele6098 interesting, many thanks 👍
FAA regs (FAR 25) do not require an operable APU for dispatch. Ditto for thrust reversers.
@@Greatdome99 Okay, looks like he is in EASA territory 🙂
Apu inoperable on a new or fairly newish plane the port attachments were brand new looking…man that’s got to suck for that airline
Not necessarily inoperative by fault (edit: tho this video seems to be the case), but some airports restrict the APU usage for noise concerns.
@@KalvinjjI doubt noise regulations have anything to do with it. These air starters are the loudest thing on the airport, bar none.

Flight crews usually don’t start up until they get to a clear area like a taxiway.
If the APU works that is the way it is done. With a inoperative APU you need to start at least one engine at the gate.

Of course 787 engines don't have air starters. They have starter-generators and require 240VAC to start.
