Function
VAB 1–3
(SCRATCHPAD
EMPTY)
With valid data in the coordinate location, depression of VABs 1–3 will select the coordinates
associated with the selected VAB as the Active FLY–TO location.
VAB 1–3
(SCRATCHPAD
CONTAINS DATA)
With Coordinate, ID, Altitude or Datum data in the scratchpad, depression of VABs 1–3 will
cause the scratchpad data to be validated. If valid, the data item associated with the
depressed VAB will change to the entered value. If data is invalid, an error message will
display prompting operator to employ normal scratchpad editing rules. If the intended
destination of the entry is either the Active Fly–To or Active Target, the prompt ‘‘NO MOD TO
ACTIVE COORD” will appear in the scratchpad. This signifies that the system will not permit
the Active Fly–To or Target coordinate to be modified.
VAB 4
Toggles between UTM or L/L display formats.
VAB 5–7
(WITH
SEL:TGT
DISPLAYED)
With valid data in the coordinate location, depression of any of these VABs will select the
coordinate associated with the depressed VAB as the Active Target location.
VAB 5–7
(WITH SEL:R/B
DISPLAYED)
Displays the range and bearing (RangeXXXXXXBRGXXX.X) to the selected coordinate on
line 8.
VAB 5–7
(WITH SEL:XFR
DISPLAYED
Copies the coordinate data associated with the depressed VAB into the scratchpad.
VAB 8
Depression of this VAB allows toggling between VAB 5–7 SEL:XFR, VAB 5–7 SEL:TGT and
VAB 5–7 SEL:R/B. Upon system power–up, the system defaults to VAB 5–7 SEL:TGT.
Following selection of SEL:XFR or SEL:R/B, the system defaults back to SEL:TGT.
