General
The general section discusses IGE (In Ground Effect) hover controllability, which has been validated in winds up to 17 knots at a density altitude of 9600 feet (2930 meters). It emphasizes the importance of referring to hover performance charts for allowable gross weights and notes that performance data is based on ideal conditions.
Demonstrated Operating Temperature
This section outlines that satisfactory engine cooling has been demonstrated at an outside air temperature of 38°C (100°F) at sea level and 23°C (41°F) above ISA at altitude, indicating the operational temperature limits for the R44.
Airspeed Calibration Curve
The airspeed calibration curve provides a graphical representation of indicated airspeed (KIAS) assuming zero instrument error. This data is crucial for pilots to understand the aircraft's performance in relation to airspeed.
IGE Hover Ceiling Vs. Gross Weight
This section presents a chart detailing the IGE hover ceiling in relation to gross weight, indicating that controllability is substantiated up to 9600 feet density altitude with a 17 knot wind.
OGE Hover Ceiling Vs. Gross Weight
Similar to the IGE section, this part provides data on the OGE (Out of Ground Effect) hover ceiling versus gross weight, essential for understanding performance during takeoff and landing.
Height-Velocity Diagram
The height-velocity diagram illustrates safe operational parameters for the R44, helping pilots avoid situations that could lead to loss of control during descent.
Noise Characteristics
This section details the noise levels of the R44, which comply with FAA and ICAO regulations. It provides specific dB(A) levels for different configurations of the helicopter, ensuring compliance with noise requirements.
Safety notes
- Performance data obtained under ideal conditions; actual performance may vary significantly under different conditions.

Refer to hover performance charts for allowable gross weight. CAUTION Performance data presented in this section was obtained under ideal conditions. Performance under other conditions may be substantially less. NOTE Hover performance data given is with carburetor heat off. Full carburetor heat reduces hover ceilings by up to 2400 feet (730 meters). Indicated airspeed (KIAS) shown on charts assumes zero instrument error. DEMONSTRATED OPERATING TEMPERATURE Satisfactory engine cooling has been demonstrated to an outside air temperature of 38°C (100°F) at sea level or 23°C (41°F) above ISA at altitude.
