Utility rated Aircraft
Initial training for advanced UPRT may be performed on a Utility class aircraft. This will restrict the maneuvers performed, specifically we will not cover the negative G in Utility aircraft.
Utility aircraft may be rated to negative G, but practically speaking it is not realistic. One important finding– during negative G, the engine oil will leave the engine thru the ventilation tube – this could not only mean an unplesant cleaning job, but it should be considered a safety problem.
Since incipient spins are trained, the aircraft must be certified for spins. It is not acceptable doing incipient spins ie. on the borderline to spins, with an aircraft not approved for spins – for safety.
