- Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Landing Performance
deceleration during the landing is identical to the effect on acceleration during the takeoff. The effect of pressure altitude and ambient temperature is to define density altitude and its effect on landing performance. An increase in density altitude increases ... landing speed but does not alter the net retarding force. Thus, the aircraft at altitude lands at the same IAS as at sea level but, because of the reduced density, the TAS is greater. Since the aircraft lands at altitude…

Normal Takeoff from a Hover A normal takeoff from a hover is an orderly transition to forward flight and is executed to increase altitude safely and expeditiously. Before initiating a takeoff, the pilot should ensure that the proper checklist ... been completed and the helicopter systems are within normal limits. During the takeoff, fly a profile that avoids the cross-hatched or shaded areas of the height/velocity diagram. Technique Refer to Figure 9-12 (position 1). Bring the helicopter…

Failing to adjust the throttle to maintain proper rpm. 7. Failing to transition to a level crab to maintain ground track. Figure 9-12. The helicopter takes several positions during a normal takeoff from hover. Normal Takeoff from the Surface ... Normal takeoff from the surface is used to move the helicopter from a position on the surface into effective translational lift and a normal climb using a minimum amount of power. If the surface is dusty or covered with loose…
- Chapter 8: Flight Instruments › Altimeter Operation
altimeter indicates an altitude above the actual field elevation. If the barometric pressure setting is reset to the current altimeter setting of 29.68 "Hg, then the field elevation is again indicated on the altimeter. This pressure change ... easily noticed in flight since aircraft fly at specific altitudes. The aircraft steadily decreases true altitude while the altimeter is held constant through pilot action as discussed in the previous section. Knowing the aircraft’s altitude is vitally important…
- Chapter 11: Aircraft Performance › Takeoff and Landing Performance › Runway Surface and Gradient
Runway Surface and Gradient Runway conditions affect takeoff and landing performance. Typically, performance chart information assumes paved, level, smooth, and dry runway surfaces. Since no two runways are alike, the runway surface differs from one runway to another, as does ... runway gradient or slope. [Figure 11-15] Runway surfaces vary widely from one airport to another. The runway surface encountered may be concrete, asphalt, gravel, dirt, or grass. The runway surface for a specific airport is noted in the Chart…
- Chapter 9: Basic Flight Maneuvers › Vertical Takeoff to a Hover › Technique
Helicopters usually hover left side low due to the tail rotor thrust being counteracted by the main rotor tilt. A nose low or high condition is generally caused by loading. Once stabilized, check the engine instruments and note the power ... required to hover. Excessive movement of any flight control requires a change in the other flight controls. For example, if the helicopter drifts to one side while hovering, the pilot naturally moves the cyclic in the opposite direction. When this…
