RMI Simulator

The RMI’s compass card is slaved to your heading, and the needle always points to the station. The big advantage: you read the magnetic bearing to the station directly under the needle head — no mental arithmetic.

Reading it

• The needle head gives the magnetic bearing TO the station; the tail gives the radial you are on.
• The angle between the nose (top lubber) and the needle head is the relative bearing.
• As you fly past the station the needle swings through 90° abeam and points behind you after passage.

Try this

• Press Fly and turn to put the needle on the nose — you are now tracking directly to the station.
• Watch the radial readout (the needle tail) and confirm it is the reciprocal of the bearing to the station.
