The propeller-bladed regional aircraft manufacturer ATR is pleased to announce that it has obtained certification for the very latest innovations developed for the avionics of the ATR 42-600s and ATR 72-600s from the European Aviation Safety Agency.
The new certification concerns the LPV (Localizer Performance with Vertical guidance), RNP-AR 0.3 (Required Navigation Performance with Authorization Required) and V-NAV (Vertical Navigation) approach functionalities coupled to the autopilot. These new improvements will allow the latest generation ATRs to follow more accurate and even more secure approach trajectories thanks to satellite navigation, without requiring ground-based navigation facilities. These new features, which significantly reduce the pilot’s workload, are integrated into a new version of the ATR -600 avionics, the “Standard 2” version.
“VNAV”, coupled to the autopilot, provides vertical guidance managed by the aircraft’s navigation calculator (FMS). Based on the calculations of the FMS, the autopilot controls the aircraft to follow a specified vertical profile. This more accurately defines descent and approach trajectories, providing better safety in relation to the possible presence of obstacles. VNAV significantly reduces the workload of pilots approaching airports; this functionality is essential for RNP-AR operations.
Carmine Orsi, ATR’s Senior Vice-President Engineering, welcomed the obtaining of this certification, “which will allow ATR -600s to be even more efficient, more economic and more versatile. We are pleased to offer our operators the very latest innovations in terms of navigational aids and thus facilitate their day-to-day operations, while further increasing aviation safety and helping reduce congestion at certain airports“.
