ThedefaultNAVPageprovidesa“lookahead”
map display with your present position at the bottom
center of the page. The top of the page displays
desiredtrack(DTK),groundtrack(TRK)anddistance
todestinationwaypoint(DIS).Thebottomofthepage
indicates ground speed (GS), active to/from waypoints
(only active to, for a direct-to destination) and esti-
mated time en route. A graphic course deviation
indicator(CDI)alsoappearsatthebottomofthepage.
UnliketheangularlimitsonaCDIcoupledtoaVOR
orILSreceiver,fullscalelimitsforthisCDIaredened
by a GPS-derived distance (2.0, 1.0 or 0.3 NM). By
default,theCDIscaleautomaticallyadjuststothe
desired limits based upon the current phase of flight:
en route, terminal area or approach.
NOTE: Approaching the FAF, the GNS 500W-series
unit automatically rescales in an angular fashion. This
allows the LPV approach to be flown identically to a
standard ILS. At 2.0 NM from the FAF, CDI scaling is
tightened from 1.0 to the angular full scale deflection
defined for the approach.
You may also manually select the desired scale set-
ting as outlined in Section 9.
ThegraphicCDIshowsyourpositionatthecenter
of the indicator, relative to the desired course (the
moving course deviation needle). As with a traditional
mechanicalCDI,whenyou’reoffcoursesimplysteer
toward the needle. The TO/FROM arrow in the center
of the scale indicates whether you are heading to the
waypoint (an up arrow) or if you have passed the
waypoint (a down arrow).
The following symbols are used — on the
Default NAV Page directly above the graphic
CDI — to depict the “active leg” of a flight
plan or direct-to.
