GSA-048N Vertical Card Compass

The GSA-48N Vertical Card Compass is the latest addition to our extended range of navigational gauges. The compass is generally found in the R22 Robinson helicopter, but can be used in any type of aircraft that has replaced the fluid damped compass by a dry magnetic compass design.
The vertical card compass’s easy-to-steer-by presentation overlays a fixed miniature airplane (lubber line) over the 360 degree rotating dial. This more natural presentation of directional information gives the heading reading at 12 o’clock off the nose of the airplane and presents all quadrants in their true relation to the line of flight.

the compass card is incorporated in a housing that can be fitted on the beam between window panels
