B757 landing flap
 
Under flap usage for landings at www.757.org.uk it says for normal operations Flap 30 is used, but that some operators may also use F25 on longer runways.
Can anyone with experience tell me if Flap 30 or Flap 25 is typically the norm for landing at London's airports?

4 years of flying into and out of LGW, and I've never used flap 25..always used 30 :ok:

Our company recently changed the procedure for B757-200 to normally use flaps 25 for landing. Reason is fuel savings and less noise (plus less wear on flap mechanism). Backside is only 2 knots of higher Vref and maybe about 1 degree of higher body angle on landing.

Same as Ocean Crosser.

I do not see much of a difference between Flaps 25 and 30 landings. Having said that, if runway length is shorter, or if it's not dry, I'll always use Flaps 30.

I have started using flaps 25 on windy days and find it to be an advantage with the higher speed and more control authority.

Thanks to all those who have replied so far.

:ok:

Stilton..I guess 2 knots plus on Vref is not a higher speed

Not aware of the 757 requirements, but on the 767 flaps 25 & 30 are considered normal landing flap settings by Boeing.
Suggest you consult your company Ops Manual for requirements/recommendations.

Another good reason to use 25f on windy days. (757-200)

Came into our hub the other day w very strong winds and my FO flying at vref +20, we were about 5 kts fast and very flat.

I knew the nosewheel was clear, but not by much.

Checking the pitch readout after shutdown, ( our company prints this out for t/o and landing readings)

It showed a touchdown pitch of .4 DEGREES !

Perhaps we are too concerned about tail clearance...
