A Category B1 qualification for release automatically entitles issuing Category A Certificates of Release to Service.

In-house Training

On request, and if possible, we certainly train in your company. In this way, we become practically acquainted with your overhaul situation, suit the training subjects better, and therefore optimize the training results.

With in-house training it should not be overlooked that you, as the responsible superior, have a chance to take a close look at the seminar and convince yourself of the quality. You certainly save travelling expenses, downtime expenses are reduced to the actual training time, and your staff has the comfort of being with their families at night.
