Manufacturer performance information conveys to the remote pilot what can be expected of an
sUAS (rate of climb, takeoff roll, etc.) under ideal conditions. Prediction of performance is based
upon the conditions a manufacturer chooses but is often similar to manned aircraft calculations
which use a sea level temperature of + 15⁰C (+59⁰F) and atmospheric pressure of 29.92 Hg (1013.2
mb). This combination of temperature and pressure is called a “standard day.” When the air is at
a “standard density,” temperature and/or pressure deviations from standard will change the air
density, or the density altitude, and that change affects sUAS performance. Remote pilots should
be aware that conditions which deviate away from the manufacturer-calculated or standard
conditions will impact performance.
Relative humidity also affects density altitude but should have minimal impact on sUAS
performance. Overall, sUAS flight performance will decrease as atmospheric pressure decreases,
altitude increases (in flight or at higher launch sites), temperature increases, and marginally with
increased humidity. A combination of high temperature, high humidity, and high-altitude result
in a density altitude higher than the pressure altitude which, in turn, results in reduced aircraft
performance.
