View Full Version : 744 TE Flap Travel Times

Hi, folks.
Would anyone have the approximate travel times (on ground with normal supply of hydraulics, pref ADP's) of the TE flaps, particularly from the Flap 5 detent to the 1 detent?

During retraction I read in the manual that the Group B LE flaps start retracting at 4 1/2 units of TE travel. I assume Group B LE's still beat the TE flaps to the up position by a good margin.

If the lever is at 1 unit, do LE or TE flaps move from their current positions if you sit the flap lever halfway between the 1 and 5 gate?

Tried looking for similar postings without success (not so strange considering the request :}) .

Thanks.
Cheers.

Found an answer to this one. 32 seconds :)

I would suggest you check your source, 32s from 5 to 1 seems rather excessive, when from 0 to 30 should take from 40-55s v.v.

I should have mentioned that this was in the air (recorded by a 744 pilot). Actually, I'm wondering if this would assist times (I guess EDP's and ADP's running wouldn't hurt, either).

Thanks, Spanners.
