NOTE: If a delay in departure of a controlled flight is not properly reported, the relevant flight plan data may no longer be readily available to the appropriate ATS unit when a clearance is ultimately requested, which will consequently result in extra delay for the flight.
NOTE:  If a delay in departure (or cancellation) of an uncontrolled VFR flight is not properly reported, alerting or search and rescue action may be unnecessarily initiated when the flight fails to arrive at the destination airport within 30 minutes after its current estimated time of arrival.
a.
Whenever a flight, for which a flight plan has been submitted, is cancelled, the appropriate ATS unit shall be informed immediately.

b.
Changes to a current flight plan for a controlled flight during flight shall be reported or requested, subject to the provisions in ICAO Annex 2, 3.6.2. (Adherence to flight plan). Significant changes to a flight plan for an uncontrolled VFR flight include change in endurance or in the total number of persons on board and changes in time estimates of 30 minutes or more.

8. A report of arrival shall be made at the earliest possible moment after landing to the airport office of the arrival airport by any flight for which a flight plan has been submitted except when the arrival has been acknowledged by the local ATS unit. After landing at an airport which is not the destination airport (diversionary landing), the local ATS unit shall be specifically informed accordingly. In the absence of a local ATS unit at the airport of diversionary landing, the pilot is responsible for passing the arrival report to the destination airport.
a. Arrival reports shall contain the following elements of information:
(1)
Aircraft identification

(2)
Departure airport

(3)
Destination airport

(4)
Time of arrival

b. In the case of diversion, insert the “arrival airport”
between “destination airport” and “time of arrival.” (SPEC/ENR 1.10-1)
