An increase in ambient temperature…

  • A
    does not influence performance.
  • B
    increases or decreases performance depending on the aircraft type.
  • C
    generally reduces performance.
  • D
    increases performance.
Refer to figure.
Density Altitude
Density altitude is pressure altitude corrected for non-standard temperature.
You probably noticed that in hot days your airplane not well-performing.

That's because with hot temperatures, density altitude increases and your airplane "feels" like it's flying at a higher altitude.

Less air mass flowing over your wings prevents you from generate as much lift, and less oxygen mass in your cylinders prevents you from burning as much fuel, meaning less power.
Decreasing air density decreases performance, so be careful on hot days at high altitudes.
