An increased density altitude means a longer landing distance.

Density altitude can be calculated from atmospheric pressure and temperature (assuming dry air).

Density altitude is affected by barometric pressure, humidity and temperature.

High temperatures in summer can result in high density altitude conditions.

These speeds, in true airspeed terms, vary considerably depending upon density altitude.

"I've checked the density altitude and the weight.

At low density altitude and light loading, best performance is achieved from a slight decrease in normal airspeed.

"Density Altitude" is the pressure altitude adjusted for non-standard temperature.

Thus, in hot and humid conditions, the density altitude at a particular location may be significantly higher than the true altitude.

The following effects result from a density altitude which is higher than the actual physical altitude:

Density altitude - Altitude measured using the density of the air.

With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions.

Contributing to the accident were the downdrafts, high density altitude, and mountainous terrain."

Is there a formula that one could program a calculator (or computer) to yeld the density altitude given the listed parameters?

Both an increase in temperature and, to a much lesser degree, humidity will cause an increase in density altitude.

This combined with thinner air at the higher density altitude airfields meant spin recovery was delayed or wrong techniques used.

Combined graphs allow the pilot to predict aircraft performance for variations in density altitude, weight, and winds all on one chart.

Aviators gauge air density by calculating the density altitude.

He was way over maximum gross weight, the density altitude conditions were horrendous, and the winds had been gusting to thirty knots.

The temperature over the runway is rising, the density altitude is above eleven thousand feet, and you're going to risk everyone's life if you try it.

This is an easier formula to calculate (with great approximation) density altitude from pressure altitude .

Several factors affect the rate of descent in autorotation: density altitude, gross weight, rotor rpm, and forward airspeed.

These gas balloons float at a constant density altitude, where the balloon displaces a mass of air equal to its own mass.

On a very hot day, density altitude at an airport (especially one at a high elevation) may be so high that aircraft can not take-off.

Note that the NWS standard specifies that the density altitude should be rounded to the nearest 100 feet.
