Departure (DEP)



The role of the Departure controller is to separate departing traffic that climbs out of the airport from the traffics that are descending to land at the airport. This is a position that has to coordinate out of the ordinary instruction with Arrival controller as well as Swiss Radar.

In IVAO, for Swiss airports, the DEP position can be opened only if ARR position is already online.


Basic Knowledge Requirements

A DEP controller must be perfectly familiar with:

  • All the Basic Knowledge Required to control DEL position, GND position and TWR position
  • Traffic separation
  • TMA setup and FIR around airport
  • SSR identification
  • Short cuts and coordination


Controller in Action

The first step for the virtual controller that wants to act as DEP would be to be sure he/she is in line with the knowledge requirements highlighted above.

As this is done, the controller should load the sector file for the airport in which he/she wants to control. The sector file can be found on the welcome-site under the quicklinks.

The second step is to check the latest Handy Sheet, where all the necessary information are summarised in a single document.

In the IVAC's COMM Box the controller has to set his primary frequency in line with GND frequency for that airport. In order to do so just type //199.999  where 199.999 stands for the frequency one wants to set up.

The next step is the setup of the altitude filter. As the DEP controller is responsible for departing traffic but not for movement on the ground, the filter should be set up in such a way that he excludes all the traffics that are on the ground as well the ones above its vertical limit. In order to do so under the menu "PVD" (top left) select "PVD Options..." the controller will set Primary filter from 100 ft above ground to 2000 ft above TMA upper limit. This is for example 1'500 ft to 14'000ft at Zurich.

Once IVAC is ready, it is time to connect.

As soon as the controller is online the first priority is to create the TS channel followed by the filing of a correct ATIS. Please remember, the Tower is responsible (always) for runway selection so DEP ATIS must in line with TWR.

The station name and frequency have to be in line with guidelines from ATC Department and can be found here: LSAZ and LSAG. The remarks box must be left empty unless a special situation requires to be communicated to pilots. This is the case for "LOW VISIBILITY PROCEDURE ACTIVE" or "ALL RWYS CLOSED DUE TO EMERGENCY" or also "ALL RWYS CLOSED DO TO SNOW CLEARING". Personal message or greetings to pilots are not allowed.

Always inform nearby controllers of your presence online.

Traffics will join DEP frequency from TWR when airborne after departure. The duty of Departure controller is give a constant climb to departing traffic and transfer them to Swiss Radar. However DEP has to guarantee the traffic climbing out of the airport is separated from arrivals.
