NAVIGATION OPERATIONAL APPROVALS
The Universal UNS-1K Flight Management System, with the version
603.X software, has been demonstrated capable of and has been
shown to meet the requirements for the following operations:
Oceanic and Remote - In accordance with AC 20-130A, along
routes requiring a Long Range Navigation (LRN) System,
provided it is receiving usable signals from the GPS which
meets requirements of AC 90-94 for use as the only LRN
System sensor on these routes.
North Atlantic (NAT) Minimum Navigation Performance
Specification (MNPS) airspace - As defined in AC 91-49 and
AC 91-70, along the special routes requiring a single LRN,
provided it is receiving usable signals from the GPS which
meets requirements of AC 90-94 for use as the only LRN
System sensor on these routes.
Enroute and Terminal - In accordance with AC 20-130A and
TSO C129a B1 provided it is receiving usable signals from:
One VOR/DME or multiple DME’s.
GPS.
Instrument Approach - LOC and BC approaches in
accordance with AC 25-15 and RNAV, VOR, VOR/DME, NDB
and GPS approaches in accordance with AC 20-130A,
TSO C129a B1, TSO C115b and AC 90-94 (Phase II and III
overlay approaches and GPS only approaches), provided:
The APP annunciation is set on the PFD at the Final
Approach Fix.
The DR is not annunciated on the PFD.
The flight director is coupled to the LNAV mode (GPS only
approaches).
NOTE: AC 90-94 deals with the use of GPS in the US National
Airspace System (NAS) and in oceanic areas. 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 NAS.
RNAV Operation - In accordance with AC 90-100A, provided
FMS is receiving automatic update from GPS.
