Its really does take a while especially if we have a 4 sector day and the ground crew are waiting to go. There stuck there for about 4-6 mins depending if the engines are hot or cold. 744 is an amazing aircraft.
@@apilotslifeforme. As a TRC there are times where i hate BMR and times where i get an engine hard-on. It depends on whether my next flight has landed or not :P
@@apilotslifeforme.I'm not a pilot, let alone an engineer, but I can sense that newer generations of engines will take exponentially more time to start... And getting harder to start by using air. I read somewhere that the old JT3D can be started using wind-milling above 120 KIAS... I doubt that those new engines could be started below 200...
I was behind a 737-Max 8 today in an A320 Neo (same engines) and this question came into my head. I used to fly the 737-700; starting that is similar to what we’d call a ‘manual engine start’ in an A320, where 99.9% are automatic. The procedure is the same in a Neo but it automatically motors the LEAP engines before it decides when to put the fuel in. The ‘Motoring’ thing here on the Max answers my question, thanks.
I couldn't help but notice the extremely high TAT values shown on the engine displays - especially on the NG which shows a TAT of 84C at the end of the video. What is that about? Thanks!
Hi thanks for the comment. The TAT normally goes as high as 99c on the ground. As the pitots are heated and no cold air is blowing on them they will get hot. This is always the case on the ground with the probe switches on.. in real life and not the sim world we would put the probes on after the engines have started and part of our before taxi checks. During taxi the TAT will rise then as were on the take off roll the temperature will reduce very quickly.
The procedure is exactly the same, except on the Neo, the engine is motored for BRM automatically so it takes longer to start. Stable indications 2 4 6 3 on the CFM-56, 2 5 7 3 on the LEAP, exactly the same as on the Boeings.
I like how the max takes up 80% of the video! Nice work!
It amazes me that it takes 2.5 min to start just one engine on the max… the GE engines on the 744 we could start all 4 engines in 2.5 min

I really appreciate your well expression about Max, thanks.

Thanks a Lot Sir...great Videos and Well explained...👍👍
Great video! can you show a Max engine failure vs Severe damage video?
Good job

@@apilotslifeforme. That's really interesting! Thanks for the reply.
@AaronHastings I fly an -800 and it's always +99C on the ground. Completely normal
Thanks @Micg51!
Nice video keep up the good work!
Thank you. Stay tuned for more technical videos soon !!!
Any chance you could do a start up video A320 with CFM-56-5 vs A320neo with cfm leap1a

Great stuff!! 👌🏻
Thank you.

I thought Chris Hemsworth was narrating this
