UL10 is a H24 conditional category-2 route (CDR2) and may be planned according to the conditions published each day for airmen, available on NOP Eurocontrol portal under “European AUP/UUP”

Yearly average estimated benefits for 1 flight flying UL10, when available for planning :




3.6 tons a year 11.5 tons a year 107 minutes a year

PS : results naturally vary according to aircraft types & destinations : the closest to the final destination will benefit the more.

When UL15 (LESDO-BEGAR) is available for planning, significant additional benefits can be made as a 15NM shortcut is thus provided.

Best planning option :
During weekends : UL10 + LESDO-BEGAR (UL15), available for airlines able to plan FL350 and above.

Offering new route options to airlines within FABEC airspace

With the implementation of this new route, DSNA contributes to pave the way for the user preferred route. This particular achievement emphasizes DSNA’s utmost objectives and ongoing challenge for :

  • making more routes available from major airports inside and outside FABEC’s airspace
  • maintaining the highest safety and capacity levels combined with a positive environmental impact
  • intensifying the necessary collaboration with neighbouring ANSP (e.g NATS for this particular example)

On the ATC side

To ensure an optimal service to all airlines, Reims ATC has followed a step by step approach to implement UL10. A second assessment of winter operations will give factual elements to further develop the route offer for the addressed traffic flow. Besides, this method has permitted the achievement of a new route option that can be filed and flown without creating any particular disruption for the network.

Additional control sector layer at Marseille ACC

A new 4th layer is created for sectors G, Y, A, B above FL375 to offer more capacity for overflights cruising at FL 380 and above. Adjacent to M and F control sectors, they constitute an entire airspace available above FL375 notably for operations between Germany and the Balearic Islands.

The main objective is to achieve a better traffic balance between layers in tactical operations, and ensure through a collaborative process and in standard weather conditions their use and compatibility with the concerned traffic flows.

In case of identified traffic over deliveries, the FMP operator will suggest refiling options to partner airlines on a selected number of flights. Such process helps to alleviate a congested layer and prevents from applying a regulation.

Dividing airspace into multiple layers contributes to drive more capacity for all airspace users regardless of their cruising level if the traffic demand is optimally distributed.
