Hi,

I can answer your question. The SALS are counted as being part of the INNER 450m therefore in CAT2/3 criteria the max percentage of lights u/s is 5 %. 95% being the minimum percentage of lights serviceable within the final 450m (SALS and HIA 5 CL) . Less than this and the runway cannot be used for landing in CAT2/3 conditions.

I agree CAP 168 is a monster. Even getting into the depths of correct circuitry for AGL systems. One of those books that when you put it down , you don't want to pick it up again.
