General Procedures

Lisboa FIR

Lisboa FIR is able to handle all kinds of traffic. From the simple domestic VFR flights between the small aerodromes of Portugal to the IFR domestic flights between the four major Portuguese airports, as well as international flights in and out of the FIR.

The Lisbon FIR is also an in-and-out point for flights using North Atlantic Tracks. As any other FIR there are restricted zones, airways, sectors and local procedures to comply with.

The northbound-southbound RVSM system is implemented on this FIR. Hence, flights proceeding to the south between a directional heading of 090 degrees to 269 degrees shall fly on Odd Flight Levels (FL330, FL350), whilst flights proceeding to the north between a directional heading of 270 and 089 shall fly on Even Flight Levels (FL340, FL360).

On Lisboa FIR there are Class C Airspaces which comprise the airspace inside the Sector limits of Lisboa Control and Lisboa, Porto and Faro TMA's and CTR's, including Cascais and Porto Santo and Class G Airspaces which covers the rest of the Airspace.


Free Route Airspace

Free-route procedures are available in Lisboa FIR above FL245


This implies special procedures:

  • Overflight traffic should plan directly from Lisboa FIR entry point to Lisboa FIR exit point.
  • Arriving traffic should plan directly from Lisboa FIR entry point to the STAR initial waypoint.
  • Departing traffic should plan directly from SID final waypoint to the Lisboa FIR exit point.
  • Cross-Border - DCT - NOT allowed


Sector Limits

In our FIR the general limits are the following:

  • Lisboa Control    
    • Upper limit - FL 660
    • Lower limit - FL 095 - Over Portuguese Territory
    • Lower limit - FL 055 - Over High Seas
  • Lisboa Approach
    • Upper limit - FL245
    • Lower limit - 1000 ft
  • Porto Approach
    • Upper limit - FL115
    • Lower limit - 1000 ft
  • Faro Approach
    • Upper limit - FL115
    • Lower limit - 1000 ft
  • Madeira Approach
    • Upper limit - FL115
    • Lower limit - 1000 ft

Porto, Faro and Madeira Approach can, depending on traffic demands and coordination with adjacent sectors, increase their upper limit to 245.


Considering these limits, Controllers should keep in mind to give a altitude clearance limit hand-off to the adjacent position at a maximum of 500 ft plus or minus the limit.

Example: An aircraft climbing out of Lisboa should be authorized by the Approach controller to a maximum of FL 240; A controller should only allow a descent untill FL 250 before handing it off to the next controller.
