Limitations
The GNS-W shall be the primary RNAV system on this aircraft and meets the requirements of:
. EASA AMC20-5 requirements for use of the Navstar Global positioning system
. RNAVS5 requirements of EASA AMC20-4 (BRNAV)
e PRNAV operations in accordance with JAA TGL-10
. GPS non-precision approaches (NPA) in accordance with AMC20-27 (see 2.2 below)
. Localizer Precision with Vertical Guidance (LPV) approaches in accordance with
AMC20-28.
° GPS primary means of navigation in oceanic and remote airspace.
NB: This AFMS does not constitute an operational approval for any of the above.
The aircraft complies with the criteria of AMC20-27 for RNP approaches to LNAV/VNAV minima,
with the exception that VNAV is based on SBAS/GNSS geometric altitude.
IFR navigation predicated upon the GPS Receiver requires that:
The No.1 position GNS-W is serviceable upon dispatch of the aircraft
The second VHF navigation is serviceable upon dispatch of the aircraft
The DME is serviceable upon dispatch of the aircraft
Alternative communication systems are serviceable, e.g. the ATC transponder.
An ADF system is installed and operational when a procedure is to be flown that requires
use of an NDB
A second VHF Com is installed and operational for all flights operated in notified airspace
under Part CAT of EU965-2012.
GPS operation in oceanic and remote areas is only permitted when operation of the aircraft is
limited to latitudes between 73° North and 60° South, unless magnetic variation is manually
entered by the pilot.
Navigation predicated upon the GPS Receiver is prohibited unless the pilot verifies the data
base is current or verifies each selected waypoint for accuracy by reference to current
approved data.
Instrument approach navigation predicated upon the GPS receiver must be accomplished in
accordance with approved approach procedures that are retrieved from the GPS database.
Manual selection/ modification of waypoints is prohibited.
Autopilot-coupled instrument approaches must be flown in autopilot Approach mode (NAV mode
in some systems) replicating a standard ILS approach.
