DISTANCE TO A VHF NAVAID
The distance to a VHF navaid displays the distance when a
navaid is selected in the Primary Nav or the Bearing Ptr LSKs on
the PFD page. This distance is a terrestrial range, not slant
range, based on current GPS position to the station position from
the navigation database. The distance is computed when the
tuned navaid identifier has been decoded by the radio and the
tuned navaid is a VOR, VORTAC, ILS/DME or VOR/DME. Note
that distance is not calculated to an ILS without a co-located DME
but is calculated to a VOR even if it doesn’t have a co-located
DME.
SETTING UP THE AUTOPILOT
Avidyne recommends setting up your autopilot target bugs before
takeoff.
The keyboard has a dedicated knob along the bottom edge for
Altitude and another for Heading. The DFC100 has a dedicated
knob for Indicated Airspeed and another for Vertical Speed.
