19.207 Primary means GPS operations
-
Each person operating an aircraft under IFR using GPS equipment as a
primary means navigation system shall--
-
(2) operate the GPS equipment in accordance with the aircraft flight
manual or aircraft flight manual supplement; and
-
(3) ensure, if the aircraft is operating within the New Zealand flight
information region, that the aircraft is equipped--
- (i) for air transport operations, with at least 2 operable sole
means navigation systems other than GPS receivers. The
sole means navigation systems must be appropriate for
the route being flown; and
-
(ii) for operations other than air transport operations, with at
least 1 operable sole means navigation system other than
GPS receiver. The sole means navigation system must be
appropriate for the route being flown; and
-
(4) if intending to use a GPS based instrument approach procedure,
obtain a RAIM prediction prior to departure for the expected
time of arrival at the destination--
-
(i) using the onboard GPS receiver; or
-
(ii) from the holder of an air traffic service organisation
certificate issued under Part 172; and
-
(5) ensure that en-route and terminal navigation is conducted--
-
(i) using a GPS database containing data that is current with
respect to the current en-route and area charts applicable
to the route being flown; and
-
(ii) by cross checking each GPS database selected track and
distance between reporting points, for accuracy and
reasonableness by reference to current en-route and area
charts; and
-
(6) ensure all GPS instrument approaches are accomplished in
accordance with approved instrument approach procedures using
a GPS database containing data that is current with respect to the
current published Instrument Approach Chart for the approach
procedure being flown; and
-
(7) if, when operating in the en-route phase, a RAIM warning has
been displayed for more than ten minutes, or the GPS equipment
has operated in the DR mode for more than one minute--
-
(i) advise the appropriate controlling ATC service; and
-
(ii) verify the aircraft position every 10 minutes using
another IFR-approved navigation system; and
-
(8) not commence an instrument approach while a RAIM warning is
displayed; and
-
(9) if an alternate aerodrome is required by 91.405, ensure that--
-
(i) the alternate is served by a fully operational radio
navigation aid with a promulgated instrument approach
procedure based on other than GPS navigation; and
-
(ii) the aircraft is equipped with navigation equipment
capable of using that radio navigation aid.
