contains exactly the same information as the standard NAV 1 page but
spreads the data out across the entire screen making it even easier to
view.
5.3 The Navigation 2 Page (NAV 2)
The NAV 2 page displays the aircraft’s present position in two formats.
The first format is in terms of the distance and radial from a nearby VOR.
(Although terminal VOR’s are in the database, they are not used on this
page since many aeronautical charts do not display a compass rose
around them for orientation purposes). The second format is in latitude
and longitude.
5.4 The Navigation 3 Page (NAV 3)
The NAV 3 page displays additional supplementary navigation informa-
tion. With the KLN 90B in the normal enroute-leg mode it displays the fol-
lowing:
• Desired track (
DTK
) which is the great circle course between two way-
points. The CDI displayed on the NAV 1 page is referenced to this DTK.
• Actual track (
TK
) which is the aircraft’s present track over the ground.
• Cross track error correction - This is a text means of indicating how far
and which direction to get back on course. It is consistent with the ver-
tical deviation bar displayed on the NAV 1 page. “
FLY L 2.7 NM
” means
fly left 2.7 nautical miles to get on course.
• Minimum Safe Altitude for present position (
MSA
) -
IMPORTANT: refer
to the KLN 90B Pilot’s Guide to understand the clearance provided by
this altitude.
• Minimum Enroute Safe Altitude from present position to destination
(
ESA
).
IMPORTANT: refer to the KLN 90B Pilot’s Guide to understand
the clearance provided by this altitude.
5.5 The Navigation 4 Page (NAV 4)
The NAV 4 page is used for advisory vertical navigation (VNAV) and for
altitude alerting. Vertical navigation operation is described in the KLN 90B
Pilot’s Guide and altitude alerting is described in section 14.0.
5.6 The Navigation 5 Page (NAV 5)
The NAV 5 page provides a navigation graphics presentation. It is useful
in providing you with proper orientation of the navigation situation. In all
KLN 90B installations there are three common map orientation formats
that may be selected on the NAV 5 page: a North up display, a desired
track up display, or an an actual track up display. In addition, if the KLN
