KLX 135A is not usable for naviga-
tion, the crosstrack distance will be
dashed out (figure 3-112).
Line 3: Distance from present posi-
tion to the active waypoint and the
calculated groundspeed.
Line 4: A cyclic field which can display either bearing to the active
waypoint (To) or radial from the active waypoint (Fr) relative to the
present position. By placing the cursor over this field and pressing
the
E button, you may toggle between the two options.
NOTE: Due to “great circle” courses and magnetic variation differ-
ences between present position and the active waypoint, the To
bearing and From radial may not be exactly 180° different from each
other when the system is in the Leg mode. This condition is most
likely to occur when long distances are involved, and/or you are
operating in very northerly or southerly latitudes. See figure 3-113 for
an example depicting a case like this. The aircraft is somewhere over
Georgia, and the active waypoint is KPHX. The bearing to steer is
269°, and radial is 72°. Generally, you will want to use bearing (not
radial) when long distances are involved.
Line 4 also displays the estimated time en route (ETE) from present
position to active waypoint.
