A LT (altitude) — Height above mean sea level 
(MSL).
BRG (bearing) — The compass direction from your 
present position to a destination waypoint. 
CAS (calibrated airspeed) — Indicated airspeed 
corrected for instrument errors. 
CUM (cumulative) — The total of all legs in a flight 
plan (such as “cumulative distance”). 
DIS (distance) — The geodesic path from your...

LFOB (left-over fuel onboard) — The amount of 
fuel remaining on board after the completion of one or 
more legs of a flight plan (or a direct-to). 
LRES (left-over fuel reserve) — The amount of fuel 
remaining on board after the completion of a one or 
more legs of a flight plan (or a direct-to), expressed 
in time and based upon a known fuel consumption 
(flow) rate.

Appendix A    
NavData Card Use
The Jeppesen NavData® card supplied with your 
500W-series unit should be installed or removed only 
when the 500W-series unit is off. Insert the card with 
the swing arm handle on the left and the label facing 
up (see illustration left). If the NavData card is not 
present when the unit is turned on, you will receive 
a “No Jeppesen Aviation Database - Limited to user 
defined waypoints” message on the Database Confir
-
mation Page. If the NavData card is removed...

What is RAIM, and how does it affect approach opera-
tions? 
RAIM is an acronym for Receiver Autonomous Integ-
rity Monitoring, a GPS receiver function that performs a 
consistency check on all tracked satellites. RAIM ensures 
that the available satellite geometry will allow the receiver 
to calculate a position within a specified protection limit 
(4.0 NM for oceanic/remote and 2.0 NM for en route, 
1.0 NM for terminal and 0.3 NM for non-precision ap
-
proaches). During oceanic, en route and...

216
Why aren’t there any approaches available for my 
flight plan? 
Approaches are available for the final destination air-
port in a flight plan or as a direct-to (keep in mind that 
some VOR/VORTAC identifiers are similar to airport iden
-
tifiers). If a destination airport does not have a published 
approach, the 500W-series unit indicates “NONE” for the 
available procedures — as listed on the Airport Approach 
Page. For more information on selecting an approach, see 
Section 4 - Flight Plans.

What does the OBS key do and when do I use it?
The OBS key is used to select manual (OBS mode) or 
to suspend automatic  sequencing of waypoints. Activat
-
ing OBS mode (as indicated by an  annunciation 
directly above the OBS key) holds your current “active 
to” waypoint as your navigation reference and prevents 
the GPS from sequencing to the next waypoint. When 
OBS mode is cancelled, automatic waypoint sequencing 
is selected and the 500W-series unit automatically selects 
the next waypoint in...

218
How do I skip a waypoint in an approach, departure, 
or arrival? 
The 500W-series unit allows you to manually select 
any approach, departure or arrival leg as the active leg of 
your flight plan. This procedure is performed from the 
Active Flight Plan Page by highlighting the desired way
-
point and pressing the  direct-to key twice, then  ENT to 
approve the selection (see illustration left). The GPS then 
provides navigation along the selected flight plan leg, so 
ensure that you have clearance...

minal mode to approach mode. CDI scaling is tightened 
from 1.0 NM full scale deflection to either 0.3 NM or 2° 
full scale deflection whichever is less at the FAF. The scal
-
ing change occurs gradually over a 2 NM distance and is 
completed before crossing the FAF. If Vectors to Final is selected, the unit provides CDI 
scaling appropriate to the approach, which is typically ±2 
degrees angular from the origin of the approach. This an

gular course deviation reaches the max ±1 NM deviation

What is the correct missed approach procedure? How 
do I select the missed approach holding point? 
The 500W-series unit does not automatically sequence 
past the MAP. Waypoint sequencing  to the first waypoint 
in the missed approach procedure will be enabled when 
the  OBS key is pressed after crossing the MAP. All pub
-
lished missed approach procedures must be followed, as 
indicated on the approach plate. 
To execute the missed approach procedure prior to the 
MAP (not recommended), select the...
