Worldwide Flight Inspection

We are using the modern Automatic Flight Inspection System (AD-AFIS) manufactured by Aerodata AG, the world's leader in the manufacturing of highly sophisticated flight inspection systems.

Key features and advantages:

  • Meets the requirements of UK CAA CAP 670, ICAO Doc 8071, Annex 10, FAA Order 8200.1D, and the NATO STANAG.

  • AD-AFIS coupled with Flight Director and Autopilot to follow AFIS guidance for precision measurement with minimum deviation from the trajectory for precision guidance with minimum deviation from the set trajectory (ICAO Doc 8071 Ch 4 §4.3.17, §4.3.47).

  • AD-AFIS to minimized error contribution though human factors.

  • Independent flight inspection antennas (ICAO Doc 8071 Ch 4 §4.3.89, Attach A to Ch 1 §3.7 [c,e]).

  • Precise measurements of parameters to within <10cm Phase Differential Global Positioning System (PDGPS) accuracy.

  • Dual set of receivers simultaneously provide redundancy and reduce errors (ICAO Doc 8071 Ch 4 §4.3.90, Attach A to Ch 1 §4.1).

  • Independent onboard radio station (ICAO Doc 8071 Attach A to Ch 1 §4.4).

  • Primary flight displays in-flight inspection console for full situational awareness of the operator.

  • Post-processing by the time synchronization to achieve maximum accuracy.

  • Precise time stamps on all input sensor signal data.

  • Instant post-processing and automatically generated reports.

  • Certified by the EASA STCs.
