Esterline CMA-9000 - Fly-By Waypoints; Fly-Over Waypoints; Large Course Changes; Leg Sequencing

OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
NOTE: The missed approach waypoint is always defined as a fly-over waypoint, and cannot be converted to
fly-by. Any holding pattern defined at a waypoint is cancelled if that waypoint is converted to a fly-over
waypoint.
LEG SEQUENCING
A. FLY-BY WAYPOINTS
The FMS sequences fly-by waypoints when crossing the bisector of the active leg and next leg, or when
passing the wayline of the active leg, whichever occurs first. In certain exceptional cases where the next leg
is short, sequencing may occur based on crossing the wayline of the next leg, if that is the first situation to
occur. If the aircraft is performing a downwind approach to a runway, sequencing of the FAF will only be
possible after the aircraft has turned towards the runway.
During the first half of the fly-by leg transition, between the initial turn point and the leg switching point
(bisector), the active waypoint is displayed in white reverse video on the LEGS and PROGRESS pages.
CAUTION: If the active flight path presents unreasonable geometry (combination of ground speed, track
changes and closely located waypoints that prevent the definition of a flyable path) the crew
should be ready to disengage the LNAV.
B. LARGE COURSE CHANGES
Regardless of the phase of flight, a fly-by leg transition involving a course change greater than 125 degrees
that is not part of a published procedure, will trigger the COURSE CHANGE>125 AHEAD system alert
scratchpad message (via FMS configuration, this message can alternatively be configured as a system alert
message).
C. FLY-OVER WAYPOINTS
The FMS sequences fly-over waypoints when passing the wayline of the active leg.

NOTE: For both fly-by and fly-over waypoints, when the installed display system supports a turn
direction symbol, the FMS will display the turn point and direction for the active leg transition,
when the latter is not represented by a circular path and has a significant course change.
Depending on the installed EFIS model, the turn information may also be displayed for down-
path forced direction turns involving course change exceeding 170 degrees.
