SLOPE TAKEOFF
A slope takeoff is basically the reverse of a slope landing. [Figure 10-7] Conditions that may be associated with the slope, such as turbulence and obstacles, must

be considered during the takeoff. Planning should include suitable forced landing areas.
TECHNIQUE
Begin the takeoff by increasing r.p.m. to the normal range with the collective full down. Then, move the cyclic toward the slope (frame 1). Holding cyclic toward the slope causes the downslope skid to rise as you slowly raise the collective (frame 2). As the skid comes up, move the cyclic toward the neutral position. If properly coordinated, the helicopter should attain a level attitude as the cyclic reaches the neutral position. At the same time, use antitorque pedal pressure to maintain heading and throttle to maintain r.p.m. With the helicopter level and the cyclic centered, pause momentarily to verify everything is correct, and then gradually raise the collective to complete the liftoff (frame 3).
After reaching a hover, take care to avoid hitting the ground with the tail rotor. If an upslope wind exists, execute a crosswind takeoff and then make a turn into the wind after clearing the ground with the tail rotor.
COMMON ERRORS
1 Failure to adjust cyclic control to keep the helicopter from sliding downslope.
2 Failure to maintain proper r.p.m.
3 Holding excessive cyclic into the slope as the downslope skid is raised.
4 Turning the tail of the helicopter into the slope during takeoff.
