SARWATCH is a generic term covering SAR alerting based on either full-position procedures, scheduled reporting times or SARTIME.
Full-position procedures and scheduled reporting times are only applicable to:
- IFR flights in all airspace classes
- most monitored VFR flights operating in controlled airspace.
SARTIME is a specific time nominated by a pilot for the initiation of a SAR action if a report/communication has not been received from the pilot by the nominated Airservices Australia unit.
(E.G. Pilot Cancels SARWATCH upon safe arrival)
