− Enroute and Terminal Operation – The FMS has been
demonstrated compliant with the requirements of AC 20-130A
and AC25-15, regarding multi-sensor system IFR operation in
en-route/terminal flight, with at least a single PFD, MFD, FMS,
VOR, DME, and IRS in NAV mode operational prior to the start
of flight.
− Approach Operation – The FMS has been demonstrated
compliant with the requirements of AC 20-130A and AC25-15,
regarding multi-sensor system instrument non-precision
approach operation. The FMS has been demonstrated
compliant with AC90-94, regarding the use of GPS for non-
precision approaches. The FMS must be operated as at least a
single system, with a minimum of one PFD, MFD, and FMS
operational prior to commencing the approach. The signal
source(s) used to define the approach and on-board equipment
must be verified operational prior to commencing the approach,
as explained in the LIMITATIONS section of this supplement.
The FMS supports the following non-precision approach types:
− GPS only (type III FAA overlay definition);
− RNAV (including type II or type III FAA overlay definition);
− VOR;
− VOR-DME;
− NDB;
− NDB-DME.
NOTE: VOR and NDB based approaches include FAA type II
GPS overlays. AC 90-94 deals with the use of GPS in
the US National Airspace System (NAS). The general
approval to use GPS to fly overlay instrument
approaches as described in the AC, is initially limited to
the NAS. Refer to LIMITATIONS Section of this
Supplement, for use of GPS for non-precision
approaches outside the US NAS.
− Barometric Vertical Navigation – For airplanes with VNAV
enabled, the FMS has been demonstrated compliant with the
requirements of AC20-129, regarding the barometric vertical
navigation in en-route, terminal, and non-precision approach
operations, when used in accordance with the limitations and
operational procedures contained in this Supplement.
