Final answer:
A pilot must notify a community aerodrome radio, an air traffic control unit, and NAV CANADA of changes to flight parameters such as cruising altitude, route, and destination while in controlled airspace.
Step-by-step explanation:
In accordance with CAR 602.76(1) and (2), a pilot must notify certain parties of any changes to flight aspects such as cruising altitude, route, destination aerodrome, and more while in controlled airspace. The correct parties that should be notified include:
- A community aerodrome radio
- An air traffic control unit
- NAV CANADA, if it pertains to any alteration in the aircraft's flight path that would affect air traffic services.
Changes to cruising altitude and flight level must be communicated, as well as any adjustments to the route of flight or the destination aerodrome. Specifically, within controlled airspace, notifications must be made to a community aerodrome radio, a flight service station, NAV CANADA, and relevant air traffic control units. If there are significant changes that would impact operational decisions, a responsible person should also be informed.
