Minimum runway lighting spacing Q?
Does anyone know (and a reference) what the minimum runway lighting spacing for normal non-low visibility ops is (RPT ops at main airports)?
I was looking through the CAOs and only found a reference to a min of 90m for an ALA, but i am not sure where this applies, or if it was the correct reference i was looking for.

AIP AD1.1 para 4.4
Not sure on the CAOs but there is something in the AIP regarding this issue and controlled airports and dual circuitry, i.e. if one circuit fails the other will provide electricy to every second light and the published minimums are then multiplied by a factor of 1.5 I think.
So this doesn't give you the spacing. Well, I would imagine that the amount of spacing would determine the minimas in the first place.
Not sure if these are the facts your after but, Rwys with an instrument approach = 60m longitudinal spacing, and up to 90m for non-instrument approach rwys and for non-precision approach rwys at country aerodromes. AIP AD1.1 para 4.4 etc.
What they mean by 'up to 90m spacing' well, that could mean you have anything from 60m - 90m spacing. Nothing really set there maybe.
I hope that helps

Thanks Bort!
The dual circutry issue was what led me to track down the info - 1 circuit failed/broke at Canberra during runway works, and lighting spacing was at 120m (normally 60m). - but this was for takeoff at night VMC.
Maybe in VMC at night for takeoff there is no minimum lighting required?

Maybe I am reading to much into the particular wording....
but, the runway lights are a minimum for the airport - in terms of an airport has to meet the requirement depending on what sort of approach is going to be conducted.
If there is a requirement for low vis takeoff then there are additional requirements specified for takeoff - ie RL @ 60m, or CL Lights @ 30m.
In terms of takeoff in night VMC, I still cant find a reference to what the pilot must have as a minimum for him to takeoff.......
EG, if you are told as you line up, due to lighting failure RWY lights are 240m spacing, is this acceptable? (You can see the entire length of runway, its night, and VMC)
Fixed some sphellling

AFAIK there are no minimum runway lighting requirements for non instrument runways (by law as opposed to your company ops manuals...). Nor are there any lighting minimums for night VMC takeoff.
One section of the RFDS regularly land at (bush) strips lit by little more than two kero flares at each end and one either side at the middle. Cateye reflectors on little stands do to rest. I don't recall needing an exemption for these landings (although we needed yearly checks according to the ops manual).
