Effect of environmental elements on airplane performance related to power-on stalls (e.g., turbulence, microbursts, and high-density altitude).
Bottom line
High density altitude, the combination of high temperature and high elevation, affects aircraft performance including takeoffs, climbs, and landings. A microburst can produce headwind losses of 30–90 knots, seriously degrading performance, along with strong turbulence and hazardous wind direction changes. When simulating limited power available for high gross weight and density altitude situations, the power during the recovery should be limited to that specified.
