Aircraft cabin pressurization is a means of providing an adequate cabin environment while achieving the performance available from a supercharged engine. The Mooney M22 is a single-engine pressurized four-to-five place aircraft powered by an engine incorporating a small low cost exhaust driven turbosupercharger based on a diesel automotive unit. By means of this turbocharger, the M22 was pressurized and met its performance goals while remaining close to the same economic class as previous conventional single-engine aircraft.
