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. 

This solution addresses the definition and validation of combined vision system (CVS) using synthetic vision guidance system (SVGS) on a head-up display (HUD). To maximise the success rate of EFVS-L operations, the EFVS sensor is placed in a more favorable situation to see the required visual cues. Such operations allow the flight crew to see the visual references at 150ft height above touchdown (HAT) instead of 200ft HAT (on ILS CAT I approved for that purpose) and improve resilience in low-ceiling overcast  situations (i.e low hanging continuous clouds) and other low-visibility conditions.
