Following the delivery of the M-346, the Polish Air Force entered a transition phase and now, with this certification, Polish pilots will be able to complete at Dęblin all their advanced training up to the IFF phase. Notably, the training was certified also for
the future F-35 pilots therefore, like their 4th gen counterparts, they will only move to the United States when ready to attend the F-35 B-Course at Luke Air Force Base, Arizona. The assessment team also found room for further improvement, beginning from the number of flight simulators.
