Every request for opinions on permanent obstacles in the immediate vicinity of airports controlled by Belgocontrol is analysed by the Urbanism service. Permanent obstacles consist of e.g. buildings, power lines, antennae, transmission equipment and tall plants or vegetation.
It is verified whether there is a possible impact on the operations at and around the airport. The obstacles may not affect the air traffic controllers' view of arriving and departing aircrafts. Moreover the flight procedures (Obstacle free zones around controlled airports) are also assessed, as well as any possible interference of the obstacles with the technical installations (among other things for communication, navigation and surveillance).
The criteria used by Belgocontrol are based on existing ICA regulations, on studies carried out for Belgocontrol, on international studies that Belgocontrol participated in (among other things commissioned by Eurocontrol), on international guidelines, on information exchanged in various fora in which Belgocontrol actively participates (ICAO, Eurocontrol, etc.), on experience of other ANSPs and on Belgocontrol's own experience.

For formal opinions Belgocontrol needs a 20 to 30 day response time, depending on the type of request and the applicant body.
Belgocontrol aims to process preliminary opinions within a 1-month deadline.
For exceptional constructions (such as power lines and obstacles larger than 60 m AGL) the prime contractor has to contact Belgocontrol at least 2 months before the start of the works so as to allow any new obstacles to be published in the AIP if applicable.
