Page Display Definitions
The heading input received from an IRS or the aircraft compass sys-
tem. If HDG can be manually inserted, MAN will be displayed.
The bearing in whole degrees from the aircraft present position to
the TO waypoint.
The track angle in whole degrees.
NAVIGATION 4/4 (Page 4 of 4)
Pressing the NAV Key again will display the fourth NAVIGATION
Page and the following can be observed.
A waypoint identifier of a fix to
be overflown can be entered
here to update the system
position. (Figure 2-24)
The current composite posi-
tion (latitude and longitude)
computed in degrees, min-
utes, and hundredths of min-
utes. (Figure 2-24)
VLF, IRS/INS, VPU, and GPS:
A listing of all interfaced sensors. The radial difference between the
individual sensor position and the composite position is displayed in
nautical miles and tenths. Sensors not being used in the composite
position solution will display the radial difference in yellow. Sensors
being used will display the radial difference in green. The GPS sen-
sor will normally be the sole contributing sensor to the composite
position as long as RAIM is available. (Figure 2-24)
NOTE: IRS radial error is always green because velocity values are
used to aid GPS position.
