Depending on which aircraft you have in mind. The answer is "landing flaps" whatever that maybe for a particular aircraft. For the MD-11, it's either 35 or 50.

Depends on the aircraft and in some cases the noise certification. For example the 707 can use Flaps 50, but to be certified to stage 3 noise requirements it is restricted to Flaps 25.

Generally you are looking at settings between 25 and 50.

In most Boeing Acraft its Flap 30 i.e 30deg (i think)
Its usually full flap in an airbus (as they only have 4 stages)
Correct me if im wrong!

DC-10 is flaps 35, but they can in odd instances use 50.

Here are some typical flap landing settings, which do vary depending on airline standard procedure.

B737, Flap 30 (Flap 40 is only recommended for short fields and the -300/400/500 do not meet Chapter III regulations with this setting)
B767, Flap 30
B747, Flap 25 (some use 30).

Airbus FBW models, Flap Full (the actual degree of flaps depends on the aircraft, ie. 340-32°, 320-35°). Flap 3 may be used in some situations (340-26°, 320-22° - not 100% certain about the 320)

High flap settings such as Flap 50 are really only found on older design aircraft such as the 707 and DC-10/MD-11.

Cheers,

Justin
