Step
Procedure 6- -8 FMS Manual Position Update by
5
Review difference between the FREEZE POSITION and
the reference position. Select either CLEAR (6L) or
ENTER (6R), as shown in Figure 6--53.
DETAILS -- The FMS calculates the difference between
ZUN and the FREEZE POSITION (FMS position when the
aircraft overflew ZUN). Figure 6--53 shows the FMS
position was 3.0 NM (1.3 NM South and 2.7 NM West)
from ZUN when the aircraft flew over the navaid.
At this point, one of two selections is made. When the
ENTER prompt is pushed, a 3 NM correction is added to
the present FMS position (1.3 NM North and 2.7 NM East).
This jumps the current FMS position (that is constantly
changing) 1.3 NM North and 2.7 NM East.
NOTE:
When the CLEAR prompt is selected, no correction is
applied to the FMS position.
