Altimeter Density Altitude Lift

APRIL 30, 2025
Calculating density altitude is like filing your taxes; annoying and often neglected until the last minute, but crucially important. Why is density altitude critical to ensuring safety, what factors affect it, and how is it calculated? Today is the day that the mystery of density altitude is solved.

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.

A witness reported that they saw the airplane lift off from the runway and remain in ground effect until it crossed the departure end of the runway. Investigators noted at the time of the accident the temperature was 30 degrees Celsius, the dew point was 4 C, and the altimeter setting was 29.98. He had no further memory of the event.

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. Start by calculating the pressure altitude. Consult your POH.
