(Models 369HE/HS/HM) ROTORCRAFT FLIGHT MANUAL
Use of Chart:
The following example explains the correct use of the chart as in
Figure 5−6. To determine the maximum hover ceiling at 3.0 ft. skid height,
the pilot must know the gross weight and the outside air temperature.
Example:
Helicopter configuration:
Short landing gear
Standard engine air inlet
Engine bleed air devices OFF
250C−18 engine
Wanted: Maximum gross weight for hover at 3.0 feet skid height at
takeoff power
Known: Gross weight = 2190; Ambient Temperature = 25 ° C
Method: Select the appropriate chart (Figure 5−6 for this example). Enter
the chart at 25
°
C on the ambient temperature scale and move ver-
tically to 2190 LB (interpolation is required) and move directly to
the left to read 8000 PA as the maximum hover ceiling.
