How To - DME Unit Tuning & Operation

The Microsoft / IniBuilds F27 is equipped with a dedicated DME Receiver that can be tuned via the Lower Overhead Panel to display DME Unit readouts on the main instrument panel.

DME Radio Tuning

The DME Receiver is tuned via the the knobs on the Lower Overhead Panel. The active frequency is denoted with a DME decal above the frequency display window on the right.

DME Unit Operation

The DME Unit on the Main Instrument Panel has a knob that toggles the digital display to show three distinct, real-time navigational data points relative to a DME station:

1. DME Miles (NM): The straight-line "slant range" distance from the aircraft to the ground station in nautical miles. This is always shown on the top display.
2. KTS (Groundspeed): The speed of the aircraft moving directly toward or away from the station, measured in knots. This is shown on the bottom display when the knob is set to KTS.
3. MIN (Time-to-Station): The estimated time in minutes to reach the DME station, provided the current ground speed and direct course are maintained. This is shown on the bottom display when the knob is set to MIN.
