The identifier and frequencies are green and tuning status is white.
Note: When magnetic variation at the airplane and VOR locations are
significantly different, the ND VOR radial and ND POS green radial do not
point directly to the VOR. This difference decreases as the airplane
approaches the VOR.
Blank when in autotune.
Valid entry is a three–digit course. Data can be entered when dashes or a course
are displayed.
With a VOR approach selected, sequencing an IAF/FAF causes the FMC to
procedure autotune the VOR frequency. When the approach has a runway
waypoint, the FMC selects the inbound course.
VOR course is green. Radial is white.
Displays radial from left and right VOR stations to the airplane.
ADF
[Option – Dual ADF]
The tuning status displays adjacent to the left and right ADF frequencies. The
tuning status displays are:
• ANT (antenna) – mode optimizes audio reception and removes ADF
bearing data
• BFO (beat frequency oscillator) – mode for audio identification of stations
transmitting unmodulated continuous wave signals
Default tuning mode is ADF (no indication) giving both bearing data and audio.
Valid entries are XXX.X or XXXX.X.
Manual entry can be followed by A (ANT), B (BFO), or none, which defaults to
the ADF mode.
Frequency is cyan and status is white.
