SECTION 7-1
LATERAL NAVIGATION
CAUTION:
In case of disagreement between the published approach information and CMA-9000 FMS displayed
information, the operator
MUST
follow the published approach information.
The CMA-9000 FMS is approved for instrument approach navigation (except ILS, LOC, LOC-BC,
LDA, SDF and MLS) provided the required sensor(s) outlined below is used.
GENERAL
The navigation database can contain GPS, GPS overlay, ILS approaches and non-precision approaches.
Approach types are identified by their prefix followed by the runway number:
GPS
- GPS approach (GPS)
ILS - ILS approach (reference only)
LOC
- Localizer approach (reference only)
LOCB
- Localizer Backcourse approach (reference only)
NDB
- NDB approach (GPS or NDB)
* NDB
D
- NDB approach with DME facility (GPS or NDB/(DME))
RNAV - RNAV approach (GPS or VOR/DME)
VOR
- VOR approach (GPS or VOR)
VORD - VOR/DME approach (GPS or VOR/DME)
* Use of the DME for this approach type is optional
( ) Required sensor.
Approach transitions are appended to the route after the STAR and are usually separated from it by a route
discontinuity, unless the last waypoint of the STAR and the first waypoint of the approach transition are identical.
Approach transitions may include procedure turns. Missed approach procedures are loaded as part of the
approach. Arrival waypoints may include speed and altitude constraint advisories. Figure 7-1 shows a typical
approach involving a full procedure turn and missed approach.
If a runway is selected rather than an approach, only the runway threshold waypoint is loaded into the route.
Baro-corrected altitude is required to enable automatic sequencing of procedure legs with altitude terminations.
If the aircraft installation provides only a pressure altitude input to the CMA-9000 FMS, manual entry of the
altimeter correction on the PROGRESS 1/X page is necessary to derive the baro-corrected altitude. Refer to
the approved AFMS/RFMS for further details. When required, entry of the altimeter correction for the arrival
airport should be performed as soon as received, and prior to reaching a radial distance of 30 nm from, and an
altitude below 15,000 feet above, the arrival airport.
When the approach transition includes a procedure turn, the CMA-9000 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.
