PANSA’s Flight Inspection Service is the only entity in Poland that validates newly established and existing instrument flight procedures – conventional and area navigation (RNAV) procedures based on DME-DME distance measuring equipment and on global navigation satellite systems (GNSS). To cater for the progressing Europe-wide implementation of ground based augmentation systems (GBAS) used for satellite-based support of precision landing of aircraft, flight inspection services will be provided to check these types of systems and validate the related flight procedures.

Validation flights for RNAV instrument flight procedures (RNAV LPV) are particularly important. It turns out in practice that possible FAS DATA BLOCK errors can be detected prior to the final publication of the flight procedure, during preparations for a validation flight or during the validation flight based on a test database in the Flight Management System (FMS). The test database is a dedicated flight procedure database provided by the avionics manufacturer on order from PANSA’s Flight Inspection Service.
