High Density Altitude Advisory
Aircraft performance is significantly reduced. Expect longer takeoff rolls, reduced climb rates, and higher approach speeds. Consider using longer runways and reducing weight if possible.
Understanding Density Altitude
Density altitude is a critical factor in aviation that represents how the aircraft "feels" the altitude based on air density. High density altitude conditions significantly reduce aircraft performance and require careful consideration during flight planning.
High Density Altitude Effects
- • Longer takeoff and landing distances
- • Reduced climb performance
- • Higher true airspeeds
- • Reduced engine power output
- • Decreased propeller efficiency
Contributing Factors
- • High temperature
- • Low barometric pressure
- • High humidity (additional factor)
- • High airport elevation
- • Combination of above factors
Rule of Thumb: For every 1°C above standard temperature, add approximately 120 feet to the density altitude. Standard temperature decreases by 2°C per 1,000 feet of altitude.
Always consult your aircraft's performance charts for specific density altitude effects. Consider density altitude when planning departures from high elevation airports or during hot weather conditions. When in doubt, use longer runways and carry less weight.
