State
Description
GPS
(or LPV,
LNAV/VNAV,
LP+V, LP,
LNAV, LNAV+V
if on a RNAV
approach)
GPS is the active state (green), and all external
deviation data being transmitted by the IFD is in
reference to the active GPS leg. Note that if no
GPS leg is active or if no GPS lock, the nav
mode will be displayed in yellow. If performing a
RNAV approach, “GPS” gets replaced with the
approach type when the leg to the FAF
becomes active and either the approach is VTF
or the course to the FAF is within 45° of the final
approach course.
GPS LPV (or
LNAV/VNAV,
LP+V, LP,
LNAV, LNAV+V
)
Basic GPS is the active state (green), and the
approach type is armed (blue).
GPS VLOC GPS is the active state (green), and VLOC is
armed (blue). If the GPS flight plan contains a
VHF-based procedure or leg (e.g. localizer
final), then the nav mode will automatically
transition from GPS to VLOC when the capture
criteria have been met. While GPS is active, all
external deviation data being transmitted by the
IFD is in reference to the active GPS leg. That
transitions to VHF deviation data when the
switch to VLOC is made.
VLOC VLOC is the active state (green), and all
external deviation data being transmitted by the
IFD is in reference to the active VHF-based leg
(e.g. Inbound VOR course, localizer deviation,
etc). Note that if no VHF data is being received
(e.g. out of range, improperly tuned nav radio,
etc), the nav mode will be displayed in yellow. It
will also stay yellow until the nav channel is fully
decoded as an indication to manually tune-
identify-monitor.
