When purging a freon air conditioning system, it is important to release the charge at a slow rate. What is the reason for the slow-rate discharge?

• prevent the large amount of freon from contamination the surrounding atmosphere

During inspection of the flight control system of an airplane equipped with differential-type aileron control, side-to-side movement of the control stick will cause

• each aileron to have a greater up travel (from the streamlined position) than down travel

• each aileron to have greater down travel (from the streamlined position) than up travel
