What is density altitude in practical terms?
- A.Pressure altitude corrected for nonstandard temperature, describing how the air 'feels' to the aircraft
- B.The physical height of the airport above sea level alone
- C.The altitude shown only by a GPS receiver
Correct answer
A. Pressure altitude corrected for nonstandard temperature, describing how the air 'feels' to the aircraft
Why
Density altitude translates temperature effects into an equivalent altitude for performance. When density altitude is high, the air is less dense and lift and propulsion become less effective.
