Landing flaps depending on aircraft weight
Hello,
Just had a quick question on landing flaps usage. I'm a trainee, about to fly B777.
which flap setting do you prefer to use in relation to aircrafts' landing weight? All this time, I thought it's favorable to use flaps 30 for light weight and flaps 25 for heavy weight.
However, a captain came up to me and said I had this all wrong. Could someone explain this in little more detail? (which flap setting to use depending on the landing weight and the reason why)
Thank you in advance
