Cyclic: initiate a flare at approximately - 180 to 150 ft AGL (from SL to 10000 ft Hp), or - 140 to 130 ft AGL (from 10000 to 15000 ft Hp) applying the cyclic at approximately 5 to 7 deg/s pitch rate, to a maximum of 25 to 30 deg nose-up pitch attitude. Cyclic: hold the flare to reduce the rate of descent (500±100 ft/min) and the forward speed (30±10 KIAS). Collective pitch: adjust as required to maintain NR as high as possible (maximum 110%) during the flare. Cyclic: at approximately 20 to 30 ft AGL, forward to obtain a near level attitude (landing skid parallel to ground). Collective: as the helicopter settles, at approximately 4 ft AGL, apply as required to cushion touchdown with: - less than 50 kts ground speed (as required by surface characteristics and conditions), and - less than 400 ft/min vertical speed. Collective pitch: continue application to cushion the touchdown. Pedals: maintain direction. Note In case of contact on the aft portion of the landing skid, avoid counteracting the pitch down with cyclic.
