ENHANCED AND SYNTHETIC VISION TO EXPAND ACCESSIBILITY OF AIRPORTS
This Solution was formerly part of PJ.03a-04-W1
Medium and small airfields have limited resources to invest in advanced ground infrastructure to support all weather operations. Emerging vision-based technologies offer an alternative, which is located on board the aircraft, uses existing infrastructure and published instrument approach procedures (IAP) and can be used by all aircraft types.
SESAR research is continuing the development of enhanced flight vision systems (EFVS), as part of combined vision systems (CVS) or used in combination with synthetic vision guidance systems (SVGS), in particular through the introduction of advanced active sensors that offer enhanced penetrability in adverse conditions. These additional capabilities will increase the performance and reliability of EFVS landing operations. In doing so, the candidate solution will enable business aviation, regional as well as commercial airspace users to access all airports types – including secondary airports – possibly in all weather conditions. This reduces cancellations, diversions and delays where the aerodrome has been declared suitable for EFVS operations.
The solution scope includes the development and validation of these vision systems to allow to operate beyond published minimum (DA/H, RVR), including in Low visibility conditions. It considers their use with 3D instrument approaches, such as satellite-based augmentation system (SBAS) CAT 1, ILS CAT I or ground based augmentation system (GBAS) GAST-C guidance signals to support landing operation in most of adverse weather situations where CAT II/III instrument landing system (ILS) would otherwise be necessary.
