Chapter 7: Helicopter Performance › Performance Charts › Height/Velocity Diagram
every condition shown on a performance chart. Instead, they evaluate specific data and mathematically derive the remaining data. Height/Velocity Diagram The height/velocity (H/V) diagram shows the combinations of airspeed and height above the ground, which will allow an average pilot ... successfully complete a landing after an engine failure. By carefully studying the height/velocity diagram, a pilot is able to avoid the combinations of altitude and airspeed that may not allow sufficient time or altitude to enter a stabilized autorotative descent…

pilot flying a lower approach. Atmospheric haze can create an illusion of being at a greater distance and height from the runway. As a result, the pilot has a tendency to be low on the approach. Conversely, extremely clear ... overshoot or go around. The diffusion of light due to water particles on the windshield can adversely affect depth perception. The lights and terrain features normally used to gauge height during landing become less effective for the pilot. Flying into…
