Britex industry has introduced a test rig for testing of piv drives. This simulator works on principle of a first stage primary drive and the last stage motorized drive. The testing piv unit is driven by virtue of primary drive there by the last stage motorized drive acts as generator, which is coupled with the piv under test. This gives actual load effect on piv unit, thus giving same effect as a simulator of a cockpit of an aircraft. Britex industry has made it mandatory to test each manufactured piv gear or even required or service unit.
