Augmenting strips
In addition to the usual annotations, Caméléon lets controllers use simple gestures to link strips to the RADAR, interact with various on-line tools and communicate with other sectors.

Tap once:

Show plane on the RADAR.

Tap twice:

Show the route and other information on the RADAR.


Tap once:

Send the exit level to3 the next sector for verification by that controller.



Write a flight level:

Tell the software to interpret the level and provide feedback to the controller. If OK, send the level to on-line tools.



Write a "V" or draw a line to a beacon:

Tell the software that a new direct route has been authorized.



Tap once:

Flag this strip.

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.

Annotating strips
Controllers use agreed-upon writing conventions to annotate paper flight strips, helping them to indicate their intended actions and quickly communicate the current situation to each other.


The line shows that the next sector has agreed to this level.



Tracking changes:

The arrow shows the plane is descending to flight level 250.

Printing strips
A paper flight strip is printed for each plane entering a sector. Flight strips provide information about the aircraft and the approved flight plan, including speed, flight level and route (from beacon to beacon).

Identification section:

Air France flight 540 is a Boeing 737 traveling at a speed of 450, leaving Bordeaux and arriving at Orly airport, Paris. The pilot has requested flight level 310.


Exit Level:

The exit level to the next sector (TW) is 310.



Flight Levels:

The cleared flight level from the previous sector is 310.




Planes travel along routes identified by electronic beacons with the expected minute and arrival listed below. Here, the flight leaves the BALAN beacon at 13:13 and then passes over AMB, CDN and EPR.
