Interpreting strips
Controllers write on flight strips for different audiences: themselves, each other and as a legal record. The location identifies the purpose, facilitating interpretation by controllers and, ultimately, computers.


The circle helps the controller quickly locate all flights landing at Paris's Orly airport (LFPO).






Legal record:

The last underlined flight level indicates the last authorized flight level.



Other controllers:

The "V" tells other controllers that the plane has been authorized to go directly to EPR without passing through CDN.
