Selecting VFR for more than 3 seconds changes the ATC code to the
pre-programmed VFR code (Typically 1200). VFR is annunciated in the
display window for the 3 seconds prior to switching the programmed
code The control unit will return to the mode selected prior to making the
VFR selection.
The VFR code can be programmed to be any code by the following tech-
nique:
a. Place the function selector to VFR.
b. Select the VFR code as required.
c. Push the Ident (IDT) button, or wait 3 seconds, or rotate the Function

The TA (Traffic Advisory) mode. Activates the Mode S transponder, alti-
tude reporting and TCAS “TA ONLY” mode. Traffic will be presented on
the traffic (TA) display.. “TA” mode is annunciated in the control unit dis-
play window and “TA ONLY” will be annunciated on the TCAS traffic dis-
play(s).
The traffic display switches to the FL (flight level) display function when
the inner knob is pressed in for more than four seconds. The relative alti-
tude tags are replaced with absolute altitude (FL) tags. The traffic display
will revert to relative altitude after 15 seconds.
The FL feature is usually flagged below 18,000 feet MSL unless baro-
metric corrected altitude is available from an air data source. FL is
flagged on the IVA 81A but not on the radar indicator when used with
the GC 362A, traffic displays. If FL is selected while flagged, "FL---" is
annunciated instead of own flight level.
