An initial training is needed for every new position level (DEL, GND, TWR, APP/DEP,...)
These trainings can be done in either Zürich or Geneva.
Example: a member previously trained in Zürich for Delivery aquires the AS2 rating. Before being allowed to control Apron, he must have a training on that position.
A familiarisation training is needed for every new major airport. Major airports include Geneva and Zürich.
Example: if the trainee has had his trainings in Geneva and wants to control a position in Zürich, he has to do a training in Zürich on the highest position he is rated to control. However, he may control in Sion and Bern up to the highest position he is approved for in Geneva.
In the case of a division transfer, the new member must have a familiarisation training before controlling any position.
In any case, having a training doesn't guarantee the member will be approved for the position. The trainer has to give his explicit approval. The trainee may be requested to do another training before opening the position.
Exceptions to these rules can be granted by the training department if it is obvious that the trainee already has the required knowledge and skills for the position (i.e. previous controlling experience in real life or on other networks).
Any Switzerland staff member may observe members, and, if it is apparent that the controller has insufficient skills or knowledge for the position, may ask him to have another training before connecting again.
