Cirrus SR20 — Other Documents

This Validation Report focuses on the Cirrus SR20 and aims to assess the accuracy of the Aircraft Design Software (ADS) algorithms in modeling the aircraft's performance. The report compares flight test measurements with ADS modeling results, using data from the Pilot's Operating Handbook and the Type Certificate Data Sheet. Key aspects analyzed include drag efficiency, lift efficiency, mass efficiency, stall speeds, takeoff distances, maximum rate of climb, cruise speeds, and landing distances. The report provides detailed tables and calculations to illustrate the performance characteristics of the Cirrus SR20 under various flight conditions, making it a valuable resource for engineers and pilots seeking to understand the aircraft's performance metrics.

• The Cirrus SR20 has a maximum lift coefficient (ClMx) of 1.34 (FM) and 1.43 (ADS).
• Stall speed with flaps up is 128 km/h (FM) and 127 km/h (ADS).
• Takeoff distance at sea level for a weight of 1429 kg is 514 m (FM) and 527 m (ADS).
• The maximum rate of climb (RCMx) is 4.39 m/s (FM) and 4.40 m/s (ADS) at a weight of 1429 kg.
• Cruise speed at 610 m altitude and 90% power setting is 289 km/h (FM) and 292 km/h (ADS).
