Which term denotes altitude adjustments caused by non-standard temperature variations affecting air density?

• A. Density Altitude
• B. Deviation
• C. Direct Control
• D. Coning

Answer: (A)

Density altitude describes altitude corrections for non-standard temperature effects on air density. When temperature is higher or other non-standard conditions prevail, the air becomes less dense, so the effective altitude at which the air density matches standard conditions increases. This directly impacts rotor lift, engine and propeller performance, and is why pilots use density altitude for performance planning. The other terms don’t describe how air density and temperature shift effective altitude; they relate to navigation, control concepts, or rotor dynamics rather than air density changes.
