vertical flight

Nota Adicional1: Crews should be aware of normal vertical flight path indications so that wind shear induced deviations are more readily recognized. On take-off, this would include attitude, climb rate, and airspeed buildup. On approach, airspeed, attitude, descent rate and throttle position provide valuable information. Awareness of these indications assures that flight path degradation is recognized as soon as possible.
Contexto: Hovering is actually an element of vertical flight. Increasing the angle of attack of the rotor blades (pitch) while their velocity remains constant generates additional vertical lift and thrust and the helicopter ascends. Decreasing the pitch causes the helicopter to descend. In a no wind condition when lift and thrust are less than weight and drag, the helicopter descends vertically.; COMMON ERRORS 1. Failure to consider performance data, including height/velocity diagram. 2. Nose too low initially, causing horizontal flight rather than more vertical flight. 3. Failure to maintain maximum permissible r.p.m. 4. Abrupt control movements. 5. Failure to resume normal climb power and airspeed after clearing the obstacle.
