• ACT RTE X LEGS – active route
• MOD RTE X LEGS – modified active route
2 Leg Direction
Leg segment data in line title:
• computed course to waypoint - XXX°
• specified procedural course/track from database - XXX°
• arcs – distance in miles, ARC, turn direction (example: 24 ARC L)
• heading leg segments – XXX° HDG
• track leg segments – XXX° TRK
• special procedural instructions from database - HOLD AT, PROC TURN
Directions are magnetic unless followed by T (131° T).
Calculated great circle route leg directions may be different than chart values.
Dashes display for an undefined course.

• altitude entry can be feet or flight level
• XXX/XXXXX – airspeed/altitude entered simultaneously
• XXX, XXXX, XXXXX or /XXX, /XXXX, /XXXXX – altitude only, less
than cruise altitude
• enter FL190 or 19,000 feet as 190 or 19000. Enter FL090 or 9,000 feet as
090 or 9000. Enter 900 feet as 009 or 0900. Enter 90 feet as 0090
