CS AWO.B.CATI.101 Applicability
ED Decision 2022/007/R
An aeroplane with a basic airworthiness approval for instrument flight rules (IFR) operations shall be eligible to perform xLS approaches down to a decision height (DH) of 60 m (200 ft), provided that the necessary xLS receiver(s) and instruments and their installation have been approved in accordance with the relevant specifications of CS-23 and CS-25.

xLS (landing system)
An xLS (landing system) is a navigation means (facilities external to the aircraft) that provides to the crew and the aircraft systems deviations from ideal approach and landing lateral and vertical trajectories. The combination of navigation means, crew and aircraft system has been demonstrated to provide the required minimum performance for the intended decision altitude/height (DA/H) or no decision height (DH). If required, the xLS can provide relevant distance information. The xLS can also apply to low-visibility take-offs.

AMC AWO.B.CATI.102 Terminology
ED Decision 2022/007/R
xLS (landing system)
Previously, landing systems were constrained to instrument landing systems (ILSs); however, the term ‘xLS’ now includes identified means such as microwave landing system (MLS), ground-based augmented (GBAS) landing system, space-based augmented landing system (SBAS/LPV) or any other system (or combination of systems).
