Navigation Functions

Built-in GPS and Bluetooth® redefined navigation in the A25N. Design flight plans with an Android™ or iOS™ device and import them into the A25 with the Bluetooth® feature. While using GPS, the waypoint NAV will guide pilots to their destination. Up to 10 flight plans and 300 waypoints can be stored in the A25. Other navigational features, like VOR indicators, can help keep a pilot’s heading precise and alert them if they divert from course. All these functions and more increase safety up in the air.

VOR navigation functions

VOR Navigation Functions

  • CDI (Course Deviation Indicator) looks like a real VOR instrument and displays any deviation from your course.
  • OBS (Omni Bearing Selector) enables you to change course from your original flight plan.
  • TO-FROM indicator shows the position relationship between your aircraft and the course selected by the OBS.
  • ABSS (Automatic Bearing Set System) enables you to set the current course as a new course.
