What are CAT II/III airport light requirements??

[PaddyMcGinty]

Here's a scenario:

Crew, aircraft are fully CAT III capeable, LVOs in force at the arrival airport.

However the airport is reporting reduced approach light system. CL, edge lights are all fully serviceable.

RVRs is 700m.

My question is can I commence a CAT II/III approach into this airport with downgraded approach lights? My DH would be 50ft on a CATIIIA approach which would mean the approach lights would be behind me and wouldn't matter then but are they legally requiried?

Many thanks for your input.

check your ops manual,

part a!

Yes I have been through the Part A and it says nothing about runway lighting requirements apart from needing to see 3 lateral lights at your DH to complete the landing. Does this mean that you could do the approach with no approach lights at all as long as you see those 3 at DH your happy?

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

Do an autoland. The plane doesn't need lights

ps EU Ops 1.4 etc might help

Yes, a failure of the complete approach lighting system is not allowed if the Decision height is greater than 50ft. So for a planned approach with a decision height of 50ft or less, the complete approach light system is not a requirement.

Qualified by your own company Op's manual requirements of course.
