  when flying at night depend on outside conditions. Flying on a bright, clear, moonlit evening when the visibility is good, and the wind is calm is not much different from flying during the day. However, if flying ... event of an emergency, as it is more difficult to find a place to land and determine wind direction and speed. At night, rely more heavily on the aircraft systems, such as lights, flight instruments, and navigation equipment…

  Sample Hover Problem 3 Using Figure 7-6, determine what torque is required to hover. Use the following conditions: First, enter the chart at 9,500 feet pressure altitude, then move right to outside air temperature, 0 °C. From that ... available. If there is a surplus of power available, the helicopter can climb vertically, so VX is zero. Wind direction and speed have an effect on climb performance, but it is often misunderstood. Airspeed is the speed…
