Which term is used for the height read when the altimeter is set to the standard pressure of 29.92 inHg?

• A. Pressure Altitude
• B. True Altitude
• C. Density Altitude
• D. Absolute Altitude

Answer: (A)

When the altimeter is set to the standard pressure of 29.92 inHg, the reading represents pressure altitude—the vertical distance above the standard datum plane where the pressure is 29.92 inHg. This value is used for flight levels and performance planning in a standard atmosphere and does not account for nonstandard temperatures. True altitude is height above mean sea level, density altitude adds the effect of temperature to the pressure altitude, and absolute altitude is height above the terrain.
