(b) Departure
At system initialisation, the flight crew must confirm that the navigation database
is current and verify that the aircraft position has been entered correctly. The ac-
tive flight plan should be checked by comparing the charts, SID or other applica-
ble documents, with the map display. This includes confirmation of the waypoint
sequence, reasonableness of track angles and distances, any altitude or speed con-
straints, and, where possible, which waypoints are fly-by and which are fly-over.
If required by a procedure, a check will need to be made to confirm that updating
will use a specific navigation aid(s), or to confirm exclusion of a specific naviga-
tion aid. A procedure shall not be used if doubt exists as to the validity of the pro-
cedure in the navigation database.
The creation of new waypoints by manual entry into the RNAV system by the
flight crew is not permitted as it would invalidate the affected P-RNAV pro-
cedure.
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. This may include the insertion in the flight plan of waypoints loaded from
the database.
During the procedure and where feasible, flight progress should be monitored for
navigational reasonableness, by cross-checks, with conventional navigation aids
using the primary display.
(c) Arrival
Prior to the arrival phase, the flight crew should verify that the correct terminal
procedure has been loaded. The active flight plan should be checked by compar-
ing the charts with the map display. This includes confirmation of the waypoint
sequence, reasonableness of track angles and distances, any altitude or speed con-
straints, and, where possible, which waypoints are fly-by and which are fly-over.
If required by a procedure, a check will need to be made to confirm that updating
will exclude a particular navigation aid. A procedure shall not be used if doubt ex-
ists as to the validity of the procedure in the navigation database.
Note: as a minimum, the arrival checks could be a simple inspection of a suitable
map display that achieves the objectives of this paragraph.
The creation of new waypoints by manual entry into the RNAV system by the
flight crew would invalidate the P-RNAV procedure and is not permitted.
Where the contingency to revert to a conventional arrival procedure is required,
the flight crew must make the necessary preparation.
During the procedure and where feasible, flight progress should be monitored for
navigational reasonableness by cross-checks with conventional navigation aids us-
ing the primary display.
