  Navigation & Compass Settings

  COMPASS MODE

  Controls how the aircraft's orientation is determined and displayed.

  Options:

  - AUTO - Automatically switches between Track and Heading based on speed

  - TRACK - Always uses GPS track over ground (moving direction)

  - HEADING - Always uses device magnetic compass (aircraft pointing direction)

  When to Use:

  - AUTO: Recommended for most flying - uses track when moving, heading when stationary

  - TRACK: Ground reference navigation, GPS-based flight following

  - HEADING: Traditional compass navigation, maintaining specific headings

  AUTO SPEED THRESHOLD

  Sets the switching speed for AUTO compass mode.

  Options:

  - 3 KT - Traditional threshold for general aviation (default)

  - 10 KT - Higher threshold for taxi operations or faster aircraft

  - 30 KT - Commercial aviation threshold for high-speed aircraft

  Technical Detail:

  When in AUTO mode and ground speed drops below threshold, display switches from GPS

  track to magnetic heading for more stable indication during slow flight or ground

  operations.
