rough or isolated terrain, the pilot should brief all occupants regarding the location of maps and survival equipment. 6. Passengers should be informed as to what actions and precautions to take in the event of an emergency, such ... high vertical impact (erect with back firmly against the seat back); and when and how to exit. Ensure that passengers are aware of the location of the fire extinguisher, survival equipment and, if equipped, how to use and locate…
- Chapter 2: Aerodynamics of Flight › Forward Flight › Dissymmetry of Lift
Therefore, as a result of the relative wind speed, the advancing blade side of the rotor disk can produce more lift than the retreating blade side. [Figure 2-36] If this condition were allowed to exist, a helicopter with ... counterclockwise main rotor blade rotation would roll to the left because of the difference in lift. In reality, the main rotor blades flap and feather automatically to equalize lift across the rotor disk. Articulated rotor disks, usually with three…

make major adjustments to the flight controls. [Figure 2-34] Airflow in Forward Flight Airflow across the rotor disk in forward flight varies from airflow at a hover. In forward flight, air flows opposite the aircraft’s flightpath. The velocity ... this air flow equals the helicopter’s forward speed. Because the rotor blades turn in a circular pattern, the velocity of airflow across a blade depends on the position of the blade in the plane of rotation at a given…
- 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…
- 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…
