Option 2: Using the POS field
For IRS equipped systems, the ramp or alignment LAT/LONG posi-
tion should be inserted as the Initialization Position using POS
Coordinates.
1. Line Select Key - DEPRESS (cursor over POS field).
2. POS Coordinates - VERIFY. Coordinates displayed are the
computed position when the system was shutdown. If correct,
these coordinates may be used as the Departure Position.
If Incorrect:
a. Latitude - INSERT N or S first, then 6 numbers (degrees,
minutes, and hundredths).
b. ENT Key - DEPRESS. (See Note)
c. Longitude - INSERT E or W first, then 7 numbers (degrees,
minutes, and hundredths).
NOTE: If coordinate field flashes after entry, verify coordinates and
depress ENT again. Coordinate field will flash if the entered value
varies more than 10 arc minutes from the displayed value.
If only one coordinate is in error, it may be updated individually by
depressing N, S, E, or W Key to access the desired field.
3. ENT Key - DEPRESS.
If AFIS is not installed in the system, The FLIGHT PLAN LIST Page
will now be displayed. A Flight Plan may be selected by bringing the
cursor on to the FLIGHT PLAN LIST Page over the desired flight
plan number and pressing ENT.
NOTE: If necessary, use the PRV or NXT Key to cycle through all
available FLIGHT PLAN LIST Pages.
If the desired flight plan does not appear, a new flight plan may be
created. (See Building Flight Plans)
If AFIS is installed in the system, the display will automatically
advance to the AFIS Flight Plan Page. Here a flight plan may be
selected from the disc that has been inserted in the AFIS DTU prior
to turning on the system. (Refer to Section 7)
