Study Notes
Types of Altitude
- Absolute Altitude: Measures the vertical distance of an aircraft above the terrain surface.
- True Altitude: Represents the vertical distance of an aircraft above mean sea level.
- Density Altitude: The altitude corrected for nonstandard temperature, reflecting the air density's effect on performance.
- Pressure Altitude: The altitude indicated when the altimeter is set to the standard pressure setting of 29.92 inHg.
Relationships Between Altitudes
- Pressure altitude equals density altitude only under conditions of standard temperature.
- Indicated altitude matches true altitude specifically at sea level under standard atmospheric conditions.
- Pressure altitude aligns with true altitude when standard atmospheric conditions are in effect.
Altimeter Settings
- The altimeter setting is adjusted so that the barometric pressure scale shows true altitude at the field elevation, ensuring accurate altitude readings.
