Flight Progress Strips carry all  mandatory information of the filed Flight Plan. Put into a bay in a timely order they give controllers a picture on which planning is based.

Controllers use this  picture for

• Preplanning of  traffic.
• Updating of strips  according to the actual traffic flow.
• Documentation of  clearances issued.

For all flights passing through our area identical strips will be printed for all specified  control point crossed along the filed flight plan route.

In the trajectory box  in the middle of the strip, consisting of nine smaller boxes, the direction of  flight is shown, the point to which the flight is heading, being printed in  negative.

Strips are printed for  each sector 20 min. before the aircraft is expected to enter the sector but at  least 3 min before entering the UIR for all sectors concerned  ( those system  parameters can be changed).
