RNAV/RNP NAVIGATION ELIGIBILITY
Section 4 – Normal procedures
ADDITIONAL GUIDANCE FOR RNAV GPS
Route modifications in the terminal area may take the form of radar headings or
‗direct to‘ clearances and the flight crew must be capable of reacting in a timely
fashion.
Although a particular method is not mandated, any published altitude and speed
constraints must be observed.
In the event that either the GPS or the EGNOS signal is not available at the desti-
nation, by the nature of the system, and its susceptibility to interference, there ex-
ists the possibility that it will also be unavailable over a wide area. Therefore it is
probable that the signal will also be unavailable at a nearby diversion aerodrome.
Notwithstanding any normal operational requirements for the identification of an
alternate aerodrome, where a RNAV approach is to be flown in conditions where
a visual approach will not be possible; pilots should always ensure that either:
1) A different type of approach system is available at the destination, not de-
pendent on GPS data and for which the weather is forecast to be suitable to
enable a landing to be made from that approach, or;
2) There is at least one alternate destination within range, where a different type
of approach system is available, which is not dependent on GPS data and for
which the weather is forecast to be suitable to enable a landing to be made
from that approach.
9.1 APPROACH APPLICATIONS
When GPS is not approved for the selected final approach course, the
message “NOT APPROVED FOR GPS” is displayed. GPS provides
guidance for the approach, but the HIS must be switched to a NAV re-
ceiver to fly the final course of the approach.
If certain GPS parameters (SBAS, RAIM, etc.) are not available, some
published approach procedures for the desired airport may not be dis-
played in the list of available approaches.
An Approach Procedure (APPR) can be loaded at any airport that has one availa-
ble, and provides guidance for non-precision and precision approaches to airports
with published instrument approach procedures.
Only one approach can be loaded at a time in a flight plan. If an ap-
proach is loaded when another approach is already in the active flight
plan, the new approach replaces the previous approach. The route is de-
fined by selection of an approach and the transition waypoints.
