OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
The FMS steering function anticipates the next leg prior to reaching the active (TO) waypoint so that the aircraft
turns are smooth without any overshoot. Waypoints may be defined as either fly-by (with turn anticipation) or
fly-over (no turn anticipation). For fly-over transition the aircraft is considered to have passed a given point when
it has crossed the perpendicular to the desired track at that point (wayline). Thus, for leg sequencing to occur,
the aircraft needs only to pass abeam the waypoint.
For fly-by leg transition, leg switching, in most cases, occurs when the aircraft passes the bisector of the active
leg and the next leg.
After the last defined waypoint is overflown, or when a route discontinuity is active, the FMS will provide
guidance along the extension of the last leg, but will prevent autopilot-coupled navigation by disengaging the
LNAV mode of the autopilot/flight director (AP/FD) system.
Angular inputs to the FMS may be referenced to either magnetic or true north. The input mode is installation
dependent as defined in the Airplane Flight Manual Supplement. The reference used for the FMS angular
displays and outputs to the flight instruments, can also be selected by the operator.
TERMINAL AREA OPERATIONS AND GPS INSTRUMENT APPROACHES
Standard Instrument Departures (SID), Airways, Standard Terminal Arrival Routes (STAR), STAR transitions,
GPS and GPS overlay instrument approaches, and approach transitions, can be selected from for the
departure/arrival airports. These procedure may be modified on the LEGS pages.
The implementation of the GPS instrument approach procedures is based, not only on TSO-C129a, but also on
the evolving Required Navigation Performance (RNP) airspace concept. The transition from en-route through
terminal to non-precision approach is effectively a seamless series of waypoints/legs with progressive increases
in HSI lateral deviation display sensitivity (to reduce flight technical error), and reductions in RNP value, and
appropriately-timed alert or advisory messages.
NAVIGATION DATABASE
The navigation database includes most of the information that the operator would normally determine by
referring to the navigation charts. The database may be tailored to specific customer needs and contains such
data as en-route and terminal VHF, NDB navigation facilities, airports, waypoints, named intersections, terminal
area procedures, ... All ARINC 424 procedural legs are implemented. These leg types and their corresponding
graphical representation are illustrated in Appendix B.
PHASES OF FLIGHT
The phases of flight are defined as follows:
Approach: When below 15,000 feet AGL and within 2 nm of the FAF, with all GPS instrument approach
conditions satisfied.
Terminal: For arrivals, when below 15,000 feet AGL and within 30 nm radial distance of the arrival airport,
but not in approach phase of flight. For departures, when below 16,000 feet AGL and less than
33 nm radial distance from the departure airport.
En-route: When in neither approach nor terminal phases of flight.
