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 the effect of a temperature increase from 35 to 50 °F on the density altitude if the pressure altitude remains at 8,000 feet MSL?

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.

Flying to Oshkosh for EAA AirVenture took us over high terrain, choosing our fuel stops with density altitude in mind. On one trip home, we had a 50-knot headwind, really annoying at a true airspeed of only 125. With this airplane, DA presented a caution, but never really a threat.

However, at 5:36:23 he still had an altitude of 7025 ft MSL, i.e. a normally very “safe” pattern altitude of almost 1500 ft, and prudently began to head toward the east end of the runway. 65 kts IAS given the high density altitude. 16 seconds later, at 5:36:39 the sink rate diminished to 273 fpm.
