Omg, what a great video - I've been looking for a video with clear startup/takeoff sounds with the IAEv2500 engine for a long time and this is perfect! Loved it! Makes me want to fly down to Heathrow/back again haha (though won't be bmi anymore)
Pressurises either the green hydraulic system from yellow or vice versa if one of the systems pumps aren't running. It's a hydraulic pump and motor arrangement. The green system has no electric pump so if the electric pump is running with no engines running it will use the yellow system pressure to pressurise the green system. The same applies if only one engine is running because the engine driven pump on the other engine is not supplying pressure.

The sound quality of your camera is outstanding - what equipment are you using?

Why the YELLOW ELLEC PUMP does work while the eng 2 was started so the ENG HYD PUMP should work ?
Nice quality!
What is the loud high pitch noise that starts at 1:40?
The flaps.
Yeah ! It's definitely an amazing sound
i guess most of the passengers were afraid and thought the aircraft had problems starting engine no 1 :D
Gosh what a noise lol, it just set my dogs off barking lol. Great vid tho :)
It certainlyis.That and the PTU changing the pressure.
The barking plane :)
Love the idle
me to
Indeed! Love the IAE engines.
Oh but the ptu soooouuuundddd
Hmmmm one engine taxi!
they do that in phx ewr and other airport
I wish They flew to My home airport, Miami.
