aircraft's present position to any selected waypoint.
Unlike the other trip planning pages, in order to use
the TRI 1 and 2 pages, the KLN 90B must either be
receiving GPS signals sufficient to be in the NAV
ready status or be in the take home mode.
The TRI 1 page provides estimates of distance,
estimated

in
route,
bearing,

fuel
requirements. Refer to Figure 3-90. The TRI 2 page
displays the minimum En route Safe Altitude (ESA)
and any areas of special use airspace that are
between the present position and the selected
waypoint. Refer to Figure 3-91.
