757 Landing Flaps

Recommended Posts

What is the SOP regarding landing when relatively light? At what weight would it be appropriate to use less than full flaps on the 757?Thanks all,Brad

Everything I've ever read indicates that you never use less than full flaps on a 757 or most other big jets. Max flaps is only 30 degrees and doesn't produce any undesirable characteristics.The 727 was probably an exception to this because it had a very high sink rate at flaps 40, and given the acceleration characterics of the jet engines of the time, it was very easy to get behind the power curve. There were a number of accidents due to these factors in the early life of the plane, and as a result many (most?) carriers recommended flaps 30 approaches if the runyway length could handle the extra speed.DJ

BradFlaps full on all boeing airliners except 727 (flaps 30 instead of 40) and 737 (flaps 30 instead of 40) regardless of how heavy or light you are. The 727 and 737 were designed for some hairy approaches in mind but 99% of the time you don't use flaps 40.There is no weight were it is appropriate not to use full flaps on a 757.
