Table 5-8. VLOC Selected Course
Selection Description
Allowed (Default) Select if it is desired to allow a selected course input from the analog resolver
or ARINC 429 for VLOC operation in OBS mode.
Ignored Select if it is desired to ignore a selected course input such that the VOR valid
flag is dependent only on a valid VOR signal, with lateral deviation calculated
by another display device.
Table 5-9. V-Flag State
Selection Description
Declutter Whenever vertical deviation is invalid, the vertical deviation bar is parked in the
maximum UP position and the vertical flag is removed from view, except in the
following cases: (i) the CDI is in VLOC mode and an ILS frequency is tuned, or
(ii) the CDI is in GPS mode and a GPS approach with vertical guidance is
active. In these cases, whenever the vertical deviation is invalid, the vertical
deviation bar parks in the centered position and the vertical flag is shown.
Normal (Default) Whenever vertical deviation is invalid the vertical deviation bar parks in the
centered position and the vertical flag is shown.
NOTE
The V-Flag declutter setting should only be set for indicators in which 300mVDC is
sufficient to drive the vertical deviation bar out of view.
