Helicopter Noise and Performance Data Set 2 U.K.
Data is provided for three helicopter classes, based on maximum take-off mass:
Light helicopter (LHEL) MTOM < 3 000 kg
Medium helicopter (MHEL) 3 000 kg < MTOM < 6 000 kg
Heavy helicopter (THEL) MTOM > 6 000 kg
Default arrival and departure flight profiles are provided as fixed point profiles. Default departure flight profiles assume climb to a level flight altitude of 1 000 ft (305 m) for each helicopter class. Where the level flight portion on departure or arrival differs locally from these values, it is recommended that the default profiles are adapted to reflect local circumstances.
