Density Altitude Calculator

Calculate how the atmosphere is affecting your aircraft's performance today. 

High, Hot and Heavy

Pressure Altitude is your height corrected for non-standard pressure. Density Altitude is Pressure Altitude corrected for non-standard temperature. 

​

​On a hot summer day in the UK, your aircraft "feels" like it is flying at a much higher altitude. This results in longer take-off rolls and reduced climb rates. Always consult your POH.
