While your in the pattern listen to the engines and you can hear them come up every time they lower the flaps further. |
yup full flaps is massive drag, and also once on the ground the engines need to be spooled up for when the reversers come on and the thrust is used as braking.
not to mention if something goes wrong with the landing they need to have enough thrust to "touch and go" and try again. like if they overshoot the shorter than normal runway down in st. martins
