Final answer:
Certain reports should be made to ATC at all times without a specific request, including position reports, altitude reports, and heading changes.
Step-by-step explanation:
When operating an aircraft, there are certain reports that should be made to Air Traffic Control (ATC) at all times, even without a specific request. These reports are known as mandatory reports. They include
- Position Reports: These reports inform ATC of the aircraft's current position, altitude, and heading. They are usually made at predetermined reporting points along the flight route.
- Altitude Reports: These reports are made when there is a significant change in altitude, typically 300 feet or more.
- Heading Changes: When the aircraft changes its heading by a certain degree, usually 30 degrees or more, a report should be made to ATC.
These reports are essential for ATC to maintain a safe and efficient flow of air traffic.
