Rotorcraft Flight Manual (RTR 661).
Airspeed limit is 65 KIAS for power settings above 83% torque.
Airspeed limit with inflated pop-out floats is 80 KIAS.
Airspeed limit is 100 KIAS for any combination of doors off.
Center of Gravity (C.G.) Range
Notes:
1. Straight line variation between points shown
2. Lateral C.G. limits valid for all gross weights
Empty Weight C.G. Range None. The aircraft’s empt
y weight and empty weight C.G. must be determined
by the procedures in Section 8 of the R66 Maintenance Manual, RTR 660.
Datum 100 inches forward of main rotor centerline.
Leveling Means For weight
and balance: Level placed laterally and longitudinally on aft tunnel
cover immediately forward of aft middle seat. If cover is not straight, use keel
panel upper flanges, accessed by removing aft tunnel cover.
For rigging: Level placed on top of main
rotor hub parallel with teeter bolt.
Main rotor blades are aligned fore-aft for lateral levelling, and teeter bolt is
aligned fore-aft for longitudinal levelling.
