When I choose the F-4 in X-Plane 8 there are "buttons" labeled "flap pump" and "gear pump", whose tooltips say something like:
Manually operating and closing flaps/pumps in a failure
- How did pilots operate these hand pumps? Video is appreciated.
- How much "pumping" was needed to open and close the landing gear?
- How much "pumping" was needed to move flaps a single unit?
- Did you need to be powerful in order to operate these hand pumps?
- How did these pumps work?
