I'm flying EFIS -300's and 400's.
Many of the other pilots would have flown 200's years ago.
More than likely to climb above a VNAV constaint as one contributor has suggested.
Nope.
Isn't it commanding "Bug Speed plus 20" which is usually V2 + 20?
Nope. After N1 has been selected it will pitch for whatever speed is in the window while the A/T maintains climb thrust.
If you have remained in TOGA after the flaps have retracted and lose an engine, then if the TOGA logic still applies it may try to command a pitch attitude to bring the speed back to V2+20 (assuming it has electronically remembered what V2 was!).
I really doubt that. If its true then it needs serious condideration. I am pretty sure though that even if it did command the +20 after an engine failure it would be "bugged speed +20" not V2 +20.
BUT why do u guys hit the N1 button at 1000´? No acceleration at 1500´ for u guys down under?
Rarely. In sydney sometimes. You do it at 1500ft for noise abatement yeah?
Thanks for your comments....I'm still not sure if it's a good idea or a waste of time though.
More reading and thinking ahead. Ta
