ahramin: Sorry can't help you on the Pans ops but in north america only an approach needs to be loaded from the database, arrivals can be pilot programmed.
Not correct.
In the U.S., all
RNAV SIDs/STARs must be extracted from the database.
The pertinent reference is
AC 90-100A.
10. U.S. RNAV FLIGHT CREW OPERATING PROCEDURES.
b. General Operating Procedures. Operators and pilots should not request or file U.S. RNAV routes or procedures unless satisfying the criteria in this AC. If an aircraft not meeting these criteria receives a clearance from ATC to conduct an RNAV procedure, the pilot must advise ATC that he/she is unable to accept the clearance and request alternate instructions.
(1) The pilot should comply with any instructions or procedures identified by the manufacturer as necessary to comply with the equipment requirements of this AC.
(2) At system initialization, pilots must confirm the navigation database is current and verify the aircraft’s present position.
(3) RNAV DPs and STAR procedures must be retrieved by procedure name from the onboard navigation database and conform to the charted procedure.
(4) Whenever possible, RNAV routes should be extracted from the database in their entirety, rather than loading RNAV route waypoints from the database into the flight plan individually. Selecting and inserting individual, named fixes from the database is permitted, provided all fixes along the published route to be flown are inserted.
(5) Manual entry of waypoints using latitude/longitude or place/bearing is not permitted. Additionally, pilots must not change any RNAV DP or STAR database waypoint type from a fly-by to a fly-over or vice versa.
