The M903 digital VOR gauge is a computer based product that brings digital VOR information to the pilot at the push of a button. The unit displays the radial position of the aircraft, both to or from the VOR station. The radial readout is the actual one the aircraft is on and is updated every 0.8 seconds. The display makes the VOR step down fixes and intersections easily read with a quick glance by the pilot. The pilot can see how fast they are approaching the fixes rather than having the needle on the OBI hard over to one side. This model is front mounted and panel mounted.
