What is Understanding the Magnetic Compass about?
The magnetic compass is used to determine magnetic heading. It usually consists of magnets attached to a float inside a liquid-filled container with a rotating compass card. It is affected by metal in the airplane and electronics, causing deviation errors. Other errors include magnetic dip, northerly turning error, and acceleration/deceleration errors. To calculate compass headings from true headings, pilots use variation and deviation values, adding west variation/deviation and subtracting east variation/d
