B737-800 FLAP30 OR FLAP40 select and the main distinction
Q:usually,i can select flaps30 for landing.But I hear that Some airlines (not mine) have a Flaps 40 policy for all landings. i think that why?
-------cat 3------slipply------short runway------.......
We use flaps 30,but it's not a must.We use flaps30 most of the time (>90% of the landings we do,I guess) so why useflap40( a not so trained configuration) in a cat 3 approach?
