This document provides performance data for the Robinson R44 helicopter, specifically focusing on various performance metrics such as hover ceilings, airspeed calibration, and noise characteristics. It is intended for pilots and operators of the R44, offering essential information for safe and efficient flight operations. The data includes critical performance parameters under different conditions, ensuring pilots can make informed decisions regarding aircraft operation. The document is FAA approved and includes charts and diagrams to illustrate performance capabilities at various weights and altitudes.

• IGE hover controllability validated up to 9600 feet density altitude in 17 knot winds.
• Satisfactory engine cooling demonstrated at 38°C (100°F) at sea level.
• Hover performance data assumes carburetor heat off; full heat reduces ceilings by up to 2400 feet (730 meters).
• Indicated airspeed (KIAS) assumes zero instrument error for accurate performance assessment.
• Noise levels comply with 14 CFR Part 36, with specific dB(A) levels for different configurations.
