3. Line select the scratchpad entry to the arc's starting waypoint location.
NOTE: The display must be set to MAG (refer to Section 3, Angular References For Navigation And Display).
The new arc's starting waypoint is displayed with a new identifier derived from the entered radial e.g. D220J.
4. Make the modified route active by pressing [EXEC].
Once established on the arc, the HSI course pointer displays the tangential course along the arc path. Lateral
deviation is measured from this tangential course. Near the end of the arc, sequencing to the next waypoint
occurs automatically, with the turn anticipation point computed such that no overshoot of the next navigation leg
will occur up to maximum ground speed of 315 knots.
At any time on the arc, the message HIGH ARC EXIT SPEED may be generated to indicate that the
combination of true air speed and wind will cause an overshoot of the next navigation leg.
PROCEDURE TURNS
When the approach transition includes a procedure turn, the FMS creates two outbound legs based on the
procedure turn reference fix, followed by a turn in the correct direction to intercept the inbound course to the
final approach fix.
The still-air lengths of the procedure turn outbound legs are computed based on a time of 1 minute and 45
seconds respectively at a speed of 180 knots. The two outbound waypoints are named using the first three
characters of the procedure turn reference fix, with the suffix PT added. The last character (L or R) indicates the
direction of the turn at that waypoint. In addition, the courses of the two outbound legs have the legend P-T.
The FMS provides navigation and guidance in the normal fashion for the two outbound legs of the procedure
turn, followed by a turn to intercept the final approach course inbound to the final approach fix. When the
maximum allowable procedure turn distance is less than 10 nm, the length of the first outbound leg may be
reduced. As a result, navigation and guidance may sequence to the second outbound leg almost immediately
after crossing the procedure turn reference fix.
CAUTION: Even with VNAV guidance engaged, during the procedure turn, it is the responsibility of the crew to
ensure that the maximum distance from the procedure turn reference fix is not exceeded and that the
aircraft remains within protected airspace at all times. The distance-to-go shown on the PROGRESS
1/4 page cannot be used for this purpose, except when the FAF is the TO WPT. The distance from
the procedure turn reference fix can be monitored using the FIX page, as described in Section 5.
