Does The A340-600 Take Off With Full Flaps?

Thu Mar 13, 2008 8:13 pm

Just viewing this takeoff video, it appears that the A340-600 on heavy departure uses a lot of trailing edge flap for takeoff. This is probably because it cannot rotate too much due to its length, so as to avoid tailstrikes. That said, is takeoff flap setting for the long Airbus full, or partial? It looks about the same amount of flap as the -200/-300 series use for landing!
May the wind be always at your back . . . except during takeoff & landing.

only partial... I think flaps 3 is max for take off, landing 3 or full

'The A346, being longer than the A333 and A343, has a higher risk of tailstrike.
Consequently, Flap 3 is normally used for take-off.'

Hello

Having worked on the A346 I saw the pilots use flaps 3 on take off, sometimes 2 depending on the load and winds on take off...

Yes, that's right, we usually use Flap 3 for take-off on the A340-600.

The only airplane I know that uses full flaps for take off is the B-52.

Would it be possible to use Flap 1, for example, if you were lightly loaded and had a good headwind? Or would Flap 1 necessitate too much rotation for the length of the aircraft?

Not if you took off at the correct speed.

TOFL would be long though.

We usually send our figures through ACARS to calculate the takeoff performance. The optimum for take-off is automatically picked, but you may override that selection with settings of Flap 1 +F, Flap 2 or Flap 3 for take-off. If the calculations find that your configuration cannot be applied to the take-off, it will tell you it can't do it.
