Density Altitude Lift Weather 
Professional Pilot
JULY 7, 2025
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 weather was good VFR that afternoon, although the temp was 37C, nearly 100 degrees F. Ahmedabad sits nearly at sea level but density altitude that day would have been very high with aircraft performance reduced due to the high density altitude. The aircraft was found to be airworthy at takeoff.

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.

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. The calculated density altitude was 4,790 feet. He had no further memory of the event.

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.

ADS-B provides real-time traffic information and almost-live NEXRAD radar and weather data. I spent a few months researching aircraft performance and high altitude airport flying techniques. Density Altitude Piston engines, wings, and propellers lose efficiency as they climb to less dense air at higher altitudes.
