Density Altitude Lift True Airspeed 
Professional Pilot

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 Cardinal and I were fairly new to the area, but I respected its performance limitations and was careful to account for the elevation and temperature and the density altitude it would surely bring. So, what was a pilot new to the high and hot world of density altitude flying to do? More on that later. It all adds up.

Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. Factors influencing air density include altitude, temperature, pressure, and humidity. High-density altitude reduces aircraft performance, requiring flight adjustments.

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. Reducing lift puts more weight on the wheels.

He only needed a glide ratio of 14:1 to reach the airfield to arrive at a typical pattern altitude of 1,000 ft AGL. There were some patches of moderate lift and sink as would be expected on a normal summer soaring day. 65 kts IAS given the high density altitude. The reduced sink rate must have been a relief.
