  vehicles, and personnel. Figure 9-9. Hover taxi. Flying in the cross-hatched or shaded area of the height/velocity diagram. 7. Flying in a crosswind that could lead to loss of tail rotor effectiveness. 8. Excessive tail-low attitudes ... Failure to maintain alignment with direction of travel. Surface Taxi A surface taxi is used to minimize the effects of rotor downwash in wheel-type helicopters. [Figure 9-11] Surface taxiing in skid type helicopters is generally not recommended…

  Chapter 2: Aerodynamics of Flight › Hovering Flight › Translating Tendency (Drift)

  Translating Tendency (Drift) During hovering flight, a single main rotor helicopter tends to move in the direction of tail rotor thrust. This lateral (or sideward) movement is called translating tendency. [Figure 2-27] To counteract this tendency, one or more ... following features may be used. All examples are for a counterclockwise rotating main rotor disk. Figure 2-27. A tail rotor is designed to produce thrust in a direction opposite torque. The thrust produced by the tail rotor is sufficient…

  helicopter. Failure to use proper antitorque pedal control, resulting in excessive heading change. 3. Failure to maintain desired hovering height. 4. Failure to maintain proper rpm. 5. Failure to maintain alignment with direction of travel. Hovering—Sideward Flight Sideward hovering ... forward flight. During the maneuver, a constant groundspeed, altitude, and heading should be maintained. Technique Before starting sideward hovering flight, ensure the area for the hover is clear, especially at the tail rotor. Constantly monitor hover height and tail rotor…

  Chapter 2: Aerodynamics of Flight › Forward Flight › Effective Translational Lift (ETL)

  Translational Lift Improved rotor efficiency resulting from directional flight is called translational lift. The efficiency of the hovering rotor disk is greatly improved with each knot of incoming wind gained by horizontal movement of the aircraft or surface wind ... incoming wind produced by aircraft movement or surface wind enters the rotor disk, turbulence and vortices are left behind and the flow of air becomes more horizontal. In addition, the tail rotor becomes more aerodynamically efficient during the transition from…

  Chapter 2: Aerodynamics of Flight › Hovering Flight

  Hovering Flight Hovering is the most challenging part of flying a helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The end result is constant ... helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, controlling forward, backward, right and left movement…

  Chapter 3: Identifying Hazards & Associated Risks › Using the PAVE Checklist to Identify Hazards › Pilot Hazards

  Using the PAVE Checklist to Identify Hazards As described in Chapter 1, the PAVE checklist provides a means to identify hazards using four convenient hazard “buckets.” Using all four checklist categories before a flight captures most hazards normally encountered. This ... section discusses hazards associated with each category. Pilot Hazards “P” hazards can be classified in terms of both capability and aeromedical factors as follows: 1. Qualification–Does the pilot possess the appropriate pilot certificate, category, class, and type rating needed…
