WIND:
The first field displays head-
wind/tailwind in knots with an
up arrow (↑) for tailwind or a
down arrow (↓) for headwind.
The second field displays the
crosswind component in
knots with a right pointing
arrow (→) for a left cross-
wind or a left pointing arrow
(← ) for a right crosswind.
(Figure 2-22)
ETA:
Estimated Time of Arrival at the last waypoint on the Active Flight
Plan prior to a “fence” (- - - - - or ++++++ ). A “fence” is a discontinu-
ity in the flight plan. No data is computed beyond the fence and there
is no Auto Leg change across the fence. (Figure 2-22)
FUEL:
Estimated fuel remaining at destination. (Figure 2-22)
TKE:
The Track Angle Error as defined as the difference between the
desired track and the actual track in degrees. R (right) and L (left)
are displayed to show the direction of error in relation to the desired
track.
XTK:
The crosstrack distance is the lateral displacement of the aircraft in
nautical miles and tenths left or right of the desired track (125 NM
maximum). TRMNL, APRCH or ENRTE is displayed to indicate the
current CDI sensitivity. A parenthesis around any of these indicates
the displayed sensitivity has been selected manually. See Section 3
for operating procedures (Figure 2-22). Scaling for the TRMNL,
APPR, and ENRTE CDI sensitivity is as follows:
Enroute: 5NM full scale deflection.
Terminal: 1NM full scale deflection.
Approach: 0.3NM full scale deflection.
