Coupling & UncouplingCâu 17 / 60
Why should you use two low-pressure gears when starting to raise loaded landing gear rather than high gear?

c.Low gear damages the crank
d.Landing gear has only one gear
Giải thích
Many landing gear cranks have a low and a high gear. Use the low gear to start raising a heavy load because it takes less effort, then switch to high gear once the weight is off. Trying to crank a heavy load in high gear can strain the mechanism and cause injury.
