WebJun 30, 2004 · At such times of the day, plants growing at high elevations have a relative advantage, as incident sunlight increases with altitude. Gale (1972 b, 1973) predicted and demonstrated a potential increase of transpiration with altitude when there is less than the average lapse rate of ambient temperature (about 0.6 °C/100 m at mid-latitudes). WebOct 1, 2024 · Density altitude is pressure altitude corrected for non-standard temperature. When it's hot outside, your airplane doesn't perform as well. Your takeoff distance is longer, and you don't climb as fast. That's because when it's hot, density altitude increases, and your airplane "feels" like it's flying at a higher altitude. WebDensity Altitude 1. Find pressure altitude 2. Correct altitude for non-standard conditions (i.e. Outside Air Temperature) 3.
