Ryan PT-22 Recruit, at Hahnweide Oldtimers Meet 2011.
The Ryan PT-22 Recruit was a military trainer used by the United States Army Air Corps and it successor, the United States Army Air Forces for primary pilot training. It was the first monoplane that the Army had used for primary pilot training, as all previous PT aircraft were biplanes.
The PT-22 fuel system consists of a single tank mounted forward of the front cockpit. Fuel is gravity fed to the carburetor through a fuel strainer. A fuel selector valve, located on the left side of each cockpit has three positions: "main", "reserve", and "off". The "reserve" section feeds fuel from the reserve portion at the bottom of the aircraft's only fuel tank. The fuel gauge consists of a sight gauge above the tank, visible to both pilots out the front of the aircraft.
