NOTE: If aircraft is configured for dual systems no XFILL? prompt
will be displayed during a PT even if dissimilar data exists in each
system.
Estimated Time Enroute (ETE) that is dispayed after crossing the IAF
on the procedure turn is the time from the aircraft’s present position
to where the airplane intercepts the final approach course inbound
(INTCPT). After crossing this intercept point, the ETE shown will be
from the airplane’s present position to the FAF.
DIS that is displayed after crossing the IAF on the procedure turn is
the distance from the aircraft’s present position to where the airplane
intercepts the final approach course inbound (INTCPT). The DIS
shown in parentheses is the straight-line distance from the aircraft’s
present position to the procedure turn fix.
NOTE: The bearing and bearing distance are with respect to the pro-
cedure turn fix.
After crossing this intercept point the DIS shown will be from the air-
plane’s present position to the FAF and the DIS in parentheses will
be removed. TO the FAF will be displayed at this time having
changed from TO INTCPT on NAV Page1.
