General:
Provides tools to build and modify route
legs for lateral and vertical guidance.
Leg line titles (all in small font)
Each line title on the left-hand side indicates
the respective leg type, for example:
13.9 ARC R Aircraft follows a right-turn
DME arc at radius 13.9 nm.
042° Aircraft follows a 042° course
of an airway or of any other
geographically fixed, lateral
path.
044°TRK Aircraft flies a track of 044°
(without course correction).
220°HDG Aircraft flies a constant
heading of 220° (not a
course).
---° Undefined direction.
PROC TURN Procedure turn.
HOLD AT Holding pattern.
A course, heading, or track refers to true
north when the indication has a T-suffix,
otherwise it refers to magnetic north.
In the middle of the page, the line title
indicates the computed length of the leg if
applicable, or ROUTE DISCONTINUITY if
there is a gap.
The line title on the right-hand side indicates
the glide path (GP) angle if the leg belongs
to a final approach; for example, GP 3.00°.
Leg lines
The left-hand side indicates in large font
how a leg will be terminated, for example:
PERLY Identifier of a geographically
fixed waypoint; the leg
terminates when the aircraft
flies by or over this waypoint.
( 480) Conditional waypoint; the
leg terminates when the
aircraft has climbed to 480 ft.
(INTC) Conditional waypoint; the
leg terminates when the
aircraft intercepts the course
of the next leg.
JFK/03 Conditional waypoint; the
leg terminates when the
distance between the aircraft
and the JFK DME is 3 nm.
JFK180 Conditional waypoint; the
leg terminates when the
aircraft crosses the 180°
radial of the JFK VOR.
VECTORS The crew has to terminate
the leg manually by entering
the next or any other
waypoint into the first line.
(when instructed by ATC).
