## HANG TEST 

The proper weight and balance of a gyroplane without a flight manual is normally determined by conducting a hang test of the aircraft. This is achieved by remov- ing the rotor blades and suspending the aircraft by its teeter bolt, free from contact with the ground. A meas- urement is then taken, either at the keel or the rotor mast, to determine how many degrees from level the 

gyroplane hangs. This number must be within the range specified by the manufacturer. For the test to reflect the true balance of the aircraft, it is important that it be conducted using the actual weight of the pilot and all gear normally carried in flight. Additionally, the measurement should be taken both with the fuel tank full and with it empty to ensure that fuel burn does not affect the loading.
