Question 7

Flaps get stuck in position 1 and a diversion is needed. What’s the extra cost on the 300NM-trip ?

Answer 7

A clean 300 NM trip requires 5T.

Flaps stuck at “1” makes it 6T. (Holding speed fuel flow increases by 1T/h)

(Flaps stuck at 2 makes it 8T and Holding speed fuel flow increases by 1T/h - value for flaps 2, conservative for flaps 1)
