U should have a ch. named more or less "ldg minima effect due to temporarily failed or downgraded gnd equipment".
On my OM-A I have following scenarios :
App lgts out CAT II NO, CAT III only if DH blw 50 ft
App lgts out but last 210 mt. CAT II NO, CAT III no effect
App lgts out but last 420 mt. CAT II + CAT III no effect
