Cessna 150 — Performance Data

This document is a performance evaluation report for the Cessna 150 aircraft modified with a Lycoming O-320-E2D engine. Conducted by the United States Air Force Academy, the evaluation aimed to determine the aircraft's performance characteristics following the engine modification. The report includes data from 24 flights totaling 41.0 hours, focusing on various performance metrics such as cruise, climb, descent, and takeoff. The findings are intended to update the flight manual with accurate performance charts and data. The report concludes that no changes to existing performance speeds are recommended, although further testing is suggested to validate the performance data across different airframes.

• The Cessna 150 was modified with a Lycoming O-320-E2D engine, increasing horsepower from 100 to 150.
• The evaluation included 24 flights totaling 41.0 hours to assess performance characteristics.
• Cruise performance data was collected at various airspeeds (50-100 knots) and altitudes (3,000 to 12,000 feet).
• No changes to existing flight manual performance speeds were recommended after the evaluation.
• Further testing is recommended to validate performance differences between airframes.
