8.28 TAKEOFF.
If the stabilator has not begun trailing edge up movement by 30 to 50 KIAS, abort the takeoff.
Refer to the height-velocity diagram, Figures 9-2 and 9-3, for avoid areas. Since suitable landing areas are often not available, operating outside avoid areas during takeoff and climb will provide the highest margin of safety.
8.29 AFTER TAKEOFF.
Fuel transfer sequence must be
carefully planned and executed in order
to maintain CG within limits.
O.
Extended range fuel system transfer -As required.
2. OBOGS -As required.
8.30 BEFORE LANDING.
1. TAIL WHEEL switch -As required.
2.
PARKING BRAKE -As required.
3.
Crew, passengers, and mission equipment -Check.
8.31 LANDING.
During roll-on landing aerodynamic braking with aft cyclic is permitted with the tail wheel contacting the ground. Once the main wheels touchdown, the cyclic must be centered prior to reducing collec-tive. Excessive aft cyclic may cause droop stop pounding and contact between main rotor blades and other portions of the air-craft. Aerodynamic braking is prohibited once the main landing gear touches down. Use brakes to stop the aircraft.
NOTE
Because of the .at pro.le of the main trans-mission, pitching the helicopter nose up as in hover, may cause a transient drop in indi-cated main transmission oil pressure, de-pending on degree of nose-up attitude.
a.
Roll-on landing. A roll-on landing may be used when the helicopter will not sustain a hover, to avoid hovering in snow or dust, if tail rotor control is lost, or when operating with one heavy external tank.
b.
Slope landing. The tailwheel should be locked and the parking brake should be set. For slope landings and all ground operations, avoid using combinations of excessive cyclic and low col-lective settings. Where minimum collective is used, maintain cyclic near neutral position and avoid abrupt cyclic inputs. During nose-down slope landings, low-frequency oscillations may be eliminated by moving cyclic toward neutral and lowering collective.

TAIL WHEEL switch -As required.
Exterior lights -As required.
turned on. Make sure that no person is within three feet of the antenna when power is applied to the helicopter. The HF radio transmits high power electromag-netic radiation. Serious injury or death can occur if you touch the HF antenna while it is transmitting. Do not grasp, or lean against the antenna when power is applied to the helicopter.
