Refer to figure or CAP758 Figure 2.6.
Given the following information, determine the HIGE limiting mass:

RPM: 3 200
Pressure Altitude: 6 200 ft
OAT: +20°C

  • A
    1 850 lb
  • B
    780 kg
  • C
    860 kg
  • D
    850 lb

Refer to figure. 
The Figure 2.6 determines the hover ceiling gross mass IGE at the 2-foot skid height at 3 200 RPM at a given pressure altitude and temperature. Although not stated, it assumes dry air which increases the power available:

  • Enter with Pressure Altitude 6 200 ft from the left side.
  • Move horizontally to the right until intersecting the OAT +20°C.
  • Continue vertically down and read the HIGE limiting mass: approximately 860 kg or 1 900 lb.
