Position Update:
A position update must be performed to give the system an accurate
starting position. An update may be accomplished over a known
point or by using an offset. If necessary, refer to the procedure for
Position Check and Update.
11. HOLD Key - DEPRESS over known point.
12. IDENT or Known Point Coordinates - ENTER.
If Waypoint Page appears:
a. Waypoint Page Coordinates - VERIFY or INSERT.
b. ENTER Key- DEPRESS.
13. DIF - CHECK. Since the system was initialized in-flight using an
approximate position, the DIF check is not used to determine the
suitability of an update, but is used to check for reasonability or
manual entry errors.
14. ENTER Key - DEPRESS.
Enter the following information as required:
• Active Flight Plan
• Initial Leg
• Manual Magnetic Variation (only for latitudes north of 70N and
south of 60S)
MANUAL TAS ENTRY
only VLF is available
NOTE: Manual TAS cannot be entered if a valid TAS is present from
the Airdata Computer.
If the system is using an unaided VLF/OMEGA sensor (no heading,
TAS or IRS velocities available) manual TAS entry is required when
fewer than three stations are received. MAN TAS REQD message
appears on the SYSTEM MESSAGE Page.
TAS must be manually entered if the aircraft does not have an auto-
TAS system or the auto-TAS input has failed. If TAS is entered man-
ually, no wind will be displayed. If the auto-TAS input returns, it will
override the manual entry.
