From a low hover of 2 to 4 ft apply take off power ( to the short red line on the FLI) in less than 2 seconds. Basically the rate of power application is quite fast and natural to a trained collective left hand and followed by a slight trim of the collective to ensure Take off power is applied.
I suspect maybe the haze has deteriorated the engine performance but EPC was ok.
Maybe the weight given by the rig is inaccurate ( most likely) . I should have asked for a reweight but for a late arrival I won't be too popular with the passengers!
