When is an identity of a non-ADSB aircraft considered confirmed?

The identity of a non-ADSB (Automatic Dependent Surveillance-Broadcast) aircraft is considered confirmed when various verification methods are employed, as mentioned in the different options. This is an important aspect of ensuring safety and accuracy in air traffic control.

Seasonal verification focuses on periodically analyzing and confirming the identity of aircraft during different seasons, which can vary due to changes in flight paths or operations unique to certain times of the year.

A post-communication check involves confirming the identity of an aircraft after a direct exchange of communications, allowing for real-time verification of flight data and intentions.

Documentation review refers to examining flight plans and associated paperwork to ensure that the identity and intentions of the aircraft are consistent with what is being observed.

Utilizing all these methods together provides a comprehensive approach to confirming the identities of non-ADSB aircraft, making the assertion that "all options are correct" accurate. Each method contributes uniquely to the overall verification process necessary for effective air traffic control and safety management.
