Take-off flap settings for the B767-200 are 1,5,15 or 20. The actual setting used can depend on a number of factors such as aircraft take-off weight, runway surface condition and length available, obstacle clearance, ambient conditions, non-standard configurations etc.

The MD-11 takeoff flap settings is from 10 deg to 25 degrees, changeable to 1 deg. (using a dial-a-flap wheel). For the Deflected Aileron option, a discrete Flap 28 is available for takeoff in addition. Typical flap setting is 15 degrees for takeoff. A detent at 28, 35 and 50 is available with 35 and 50 used for landing.

The 777-200 flap settings detents are 1, 5, 15, 20, 25, 30. Typical takeoff flap settings are 5, 20 and 25 (in United Airlines case).

MD11Nut

I would have thought that Flaps 25 for takeoff on a B777 would have caused more drag than lift? Are you sure that this flap setting is used for takeoff?

On the MD11, i dont think that you can say that any flap setting is typical, the dial a flap setting combined with optimized takeoff charts will give you an optimized weight/temperature/runway combination.

B747-400 Flaps 20 and 10, once again depends on airline policy.

Ambasaid.
You got me on the 777-200. I meant to say 5, 15, and 20. I need to proofread what I write. Thanks

On the MD-11, unless you have a special need to a different flap setting, it is always set at 15 for takeoff (at least at McDonnell Douglas and a few airlines I'm familiar with). What you wrote is true, however.
