Q

During alternate extension of the landing gear:
- The main gears free fall and lock down.
- All three gears partially free-fall but must be locked down with hand
pump pressure.
- The main gears partially free-fall but may need to be locked down with
hand pump pressure.
- The main gears free-fall and lock down, but the nose gear extension
must be completed with hand pump pressure.

A
  • The main gears partially free-fall but may need to be locked down with
    hand pump pressure.
