What effect does high density altitude have on aircraft performance? What is the headwind component for a landing on Runway 18 if the tower reports the wind as 215° at 30 knots? 187 knots 162 knots 165 knots Correct! It increases takeoff performance. It increases engine performance. 1,300-foot increase.

Density Altitude Questions about density altitude range from computing the effects of changes in air temperature to evaluating the best response in a given flight scenario. The important thing to remember with these questions is that density altitude changes inversely with altitude.

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. Every 1000 feet we logged the time, altitude, and outside air temperature.

In the Cessna 172S Pilot’s Operating Handbook (POH), the landing distance decreases by 10% for every 9 knots of headwind. For the Cessna 172, landing distance increases by 10% for every 2 knots of tailwind. Temperature An increase in temperature will increase the density altitude.

Outside of the marine layer that incessantly taunts the coastal areas, back home your experiences with density altitude are minimal. The weather is VMC but it’s hot, and the density altitude is really creeping up there. In the time it took me to write all of this, the Density Altitude moved up to 8000’!

In still air, the climb rate under full power is likely in the range of 3-5 kts given the high density altitude environment at Rifle. That does very little when you’re in 10-20 knot sink. If that happens, the propeller causes a lot of extra drag, comparable to half-extended airbrakes.

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. The AirCam was far and away the best airplane for giving rides, screaming along at 70 knots.
