5.1.

GENERAL

The agility of the helicopter has been demonstrated by crosswinds and tail winds of up to 35
kts at a mass of 700 kg on the ground

VNE : 190 km/h – 102 kts
VFR flight authorised
IFR flight prohibited for use under CNSK2 certification
Night flying prohibited for use under CNSK2 certification
Flight in icing conditions prohibited
Emergency Auto-rotation (see 4.10)

Use maximum revs in the range « with power » (100%) during takeoff and climb out (if
necessary 108%, limited to 10 minutes) then limit to 100%.
