## GM1 ATCO.C.015(b) Application for on-the-job training instructor endorsement

SHORTENING OF THE [LICENCE](https://avioverse.aero/glossary/easa/licence) EXPERIENCE REQUIREMENT FOR OJTI

When assessing the training organisations’ request for the shortening of the licence experience requirement for OJTIs, the competent authorities should take into account the complexity of the traffic in the unit where the on-the-job instruction is provided, as well as the impact on the continuity and safety aspects of the service.
