By Karsten Shein Comm-Inst Climate Scientist QNE, QNH, and QFE describe different altitudes for different phases of flight, but also serve as pressure altitude (QNE) or density altitude (QNH). Every pilot knows that aircraft fly because the forces of lift and thrust balance or exceed the weight and drag countering them.

The result of an alteration in airflow patterns increasing induced drag about the wings of an airplane. What effect does high density altitude have on aircraft performance? What true airspeed should a pilot expect at 9,000 feet on a standard day with 65 percent maximum continuous power? What is ground effect?

Temperature An increase in temperature will increase the density altitude. A high density altitude decreases the performance of the engine and the wing. Your aircraft will fly at a faster true airspeed at higher density altitudes.
