What is the minimum decision height (DH) that can be achieved when using SA CAT I operational credits?

The DH can be reduced from the standard minimum of 200 ft down to 150 ft.

GM2 SPA.LVO.100(c) Low-visibility operations and operations with operational credits

Q: How does SA CAT I reduce the required RVR for an approach?

The lower DH (150 ft) allows a corresponding reduction in the RVR required for the approach.

Q: Is SA CAT I a separate approach classification?

No, SA CAT I is not a separate approach classification; it is an operational credit applied to a CAT I operation.

Q: What navigation solutions can be used to exploit SA CAT I operational credits?

The navigation solution may be an ILS installation with the necessary performance coupled to a suitably certified autoland system, a HUD or equivalent display system, or SVGS.

GM2 SPA.LVO.100(c) Low-visibility operations and operations with operational credits

ED Decision 2022/012/R

OPERATIONS WITH OPERATIONAL CREDITS — SPECIAL AUTHORISATION CATEGORY I (SA CAT I) OPERATIONS

SA CAT I is an operational credit that exploits a navigation solution with superior performance to that required for standard CAT I by extending the instrument segment of CAT I approach operations. This navigation solution may be an ILS installation with the necessary performance coupled to a suitably certified autoland system or a HUD or equivalent display system or SVGS. The extended instrument segment means that the DH can be reduced from the standard minimum of 200 down to 150 ft. The lower DH allows a corresponding reduction in the RVR required for the approach.

SA CAT I is not a separate approach classification; it is an operational credit applied to a CAT I operation.
