  landing gear. Some things to consider while formulating a takeoff plan are the aircraft load, height of obstacles, the shape of the area, direction of the wind, and surface conditions. Surface conditions can consist of dust, sand and snow ... well as mud and rocks. Dust landings and snow landings can lead to a brownout or whiteout condition, which is the loss of the horizon reference. Disorientation may occur, leading to ground contact, often with fatal results. Taking…

  Chapter 10: Advanced Flight Maneuvers › Shallow Approach and Running/Roll-On Landing

  Shallow Approach and Running/Roll-On Landing Use a shallow approach and running landing when a high-density altitude, a high gross weight condition, or some combination thereof, is such that a normal or steep approach cannot be made because of insufficient ... power to hover. [Figure 10-5] To compensate for this lack of power, a shallow approach and running landing makes use of translational lift until surface contact is made. If flying a wheeled helicopter, a roll-on landing…

  approach path that will serve as go/no-go points should the pilot feel any assessed parameter is being exceeded. Wind direction and velocity are assessed as a medium risk because (for this scenario) the direction of the wind is slightly offset ... from the chosen approach path, creating a 15–20° crosswind with a steady 10-knot wind. The pilot also takes into consideration that, due to the terrain, the wind direction and velocity may change during the approach. The pilot…

Avoid the misperception of an increasing rate of closure to the landing site. The apparent rate of closure ... crosswind exists, remain clear of down-drafts on the leeward or downwind side of the ridgeline. If the wind velocity makes the crosswind landing hazardous, it may be possible to make a low, coordinated turn into the wind just prior…

  Wind Shear PIREPs a. Because unexpected changes in wind speed and direction can be hazardous to aircraft operations at low altitudes on approach to and departing from airports, pilots are urged to promptly volunteer reports to controllers of wind shear ... conditions they encounter. An advance warning of this information will assist other pilots in avoiding or coping with a wind shear on approach or departure. b. When describing conditions, use of the terms “negative” or “positive” wind shear should…

If the wind velocity is 10 knots or greater, expect updrafts on the windward side and downdrafts on the lee side of obstacles ... Plan the approach with these factors in mind, but be ready to alter plans if the wind speed or direction changes. Approach A high reconnaissance should be completed before initiating the confined area approach. Start the approach phase using…
