Use 3100 rpm for hover and takeoff; add collective to establish
hover at a 3-foot skid height to check power and control response.
Adjust throttle during lift-off to maintain engine rpm.
NOTE: When max i mum per for mance is re quired, use
rpm and skid height spec i fied on the Per for mance
Charts in Sec tion V.
For climb out, apply only sufficient additional collective to maintain
ground clearance until translational lift is obtained. One inch of MP
above hover power is recommended. Do not exceed MP placard
limit.
Perform climb out at 3100 rpm. Lower nose and accelerate to climb
speed following profile in with Height Velocity Diagram (Figure
5-2). Above 450 AGL, reduce rpm to 3000 to 3100 range.
NOTE: Above the crit i cal al ti tude (al ti tude at which
full throt tle is ob tained), ex er cise cau tion to as sure that
the throt tle sys tem is not in the over ride po si tion when
re duc ing col lec tive to avert overspeed.
Avoid ex ces sive nose down at ti tude.
