OpsN and others
True, I was also taught to check the gear position by means of convex mirrors and the front wheels (cant miss that 2 foot long arms) but has anyone heard of the main gear extending in flight?
For example what would happen if the hydraulic oil was ruptured and all the fluid ran out of the system. Would the gear extend or would it remain up in the floats and not extend next time the gear was selected down?
