Emergencies and Hazards. The approach to a slope is similar  to the approach to any other landing area. During slope  operations, make allowances for wind, barriers, and forced  landing sites in case of engine failure. Since the slope may  constitute an obstruction to wind passage, anticipate turbulence  and downdrafts. A pilot usually lands a helicopter across the slope rather than  with the slope. Landing with the helicopter facing down  the slope or downhill is not recommended because of the  possibility of striking the tail rotor on the surface. helicopters with a counterclockwise rotor system, landings  can be made on steeper slopes when holding the cyclic to the  right. When landing on slopes using left cyclic, some cyclic  input must be used to overcome the translating tendency.  If wind is not a factor, consider the drifting tendency when  determining landing direction. After the downslope skid is on the surface, reduce the  collective to full down, and neutralize the cyclic and pedals  (frame 4). Normal operating rpm should be maintained  until the full weight of the helicopter is on the landing gear.  This ensures adequate rpm for immediate takeoff in case the  helicopter starts sliding down the slope. Use antitorque pedals  as necessary throughout the landing for heading control.  Before reducing the rpm, move the cyclic control as necessary  to check that the helicopter is firmly on the ground. Refer to  Figure 10-6 . At the termination of the approach, if  necessary, move the helicopter slowly toward the slope, being  careful not to turn the tail upslope. Position the helicopter  across the slope at a stabilized hover headed into the wind  over the intended landing spot (frame 1). Downward pressure  on the collective starts the helicopter descending. As the  upslope skid touches the ground, hesitate momentarily in a  level attitude, then apply slight lateral cyclic in the direction  of the slope (frame 2). This holds the skid against the slope  while the pilot continues lowering the downslope skid with  the collective. As the collective is lowered, continue to move  the cyclic toward the slope to maintain a fixed position (frame  3) The slope must be shallow enough to hold the helicopter  against it with the cyclic during the entire landing. A slope of  5° is recommended maximum for training in most helicopters.  However, additional training to the manufacturer’s  limitations may be required. Consult the Rotorcraft Flight  Manual (RFM) or Pilot’s Operating Handbook (POH) for  the specific limitations of the helicopter being flown. Be aware of any abnormal vibration or mast bumping that  signals maximum cyclic deflection. If helicopter mast  moment or slope limits are reached before the helicopter  is firmly on the ground, return the helicopter to a hover.  Select a new area with a lesser degree of slope. In most  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. 1 2 3 4 Figure 10-6.  Slope landing.  Slope Landing Technique Common Errors Slope Takeoff 1.  Failing to consider wind effects during the approach  and landing. 2.  Failing to maintain proper rpm throughout the entire  maneuver. 3.  Failure to maintain heading resulting in a turning or  pivoting motion. 4. Turning the tail of the helicopter into the  slope. 5.  Lowering the downslope skid or wheel too rapidly. 6.  Applying excessive cyclic control into the slope,  causing mast bumping. 10-8
