Runway Lights Vs Runway Flood

Tue Oct 30, 2012 6:48 am

So in light of EWR, LGA, and JFK having some submersion issues, I want to know how that floodwater effects the electronics involved with runway lights, ILS, and other systems at the airport.

I know they're supposed to handle rain, snow, and ice, but what about submersion?

Other submersion issues i've seen recently are like at SDJ and Don Muang Airport. What happens? Lots of repairs needed?

Hey Zak interesting question I'm not sure but i think they would be sealed units designed with fluds in mind.
Then again they could be old designs.

I would expect them to be designed for a couple inches of standing water. But what happens once it gets to a foot or two, I honestly have no idea.

The antennas with weather proof sealed elements is out in the open. The building with the electronics might be susceptible to water four or five feet deep.

Paging a.net member mmedford...who's probably quite busy repairing localizers and glideslope transmitters as we speak...  

I would imagine, though, that salt water is not very good for navaids, directional aids, or runway lighting   It will be interesting to see the NOTAM's for OTS equipment once the airports in the NYC area open up again...

Meh; I don't have the kind of time to explain what's going on locally here...

But; rainwater and salt water are two different breeds...rainwater we just wipe off, and it's business as usual.

With the saltwater we had; we have to rebuild everything affected.

Mir; the reason the equipment was removed from service has something to do with ICAO CoS.

From what our SOC is telling us regarding New York ops.

LGA using 13/31 with expressway visual 31 being the primary approach. 4/22 Sked to reopen later today
Approach navaids to be tested today as well. Only RNAVs approaches avail. Arrival rate of 32 planes per hour. Flights to tanker fuel into LGA

JFK. Using 13/31s. Primary approaches LOC 31L/R. 4/22L/R closed until Friday. Rnav 13L/R available. Arrival rate of 55 planes / hr

Water resistant yes.....but submerged for a long duration....very unlikely.unless some Airport is willing to spend that kind of $.
I may not win often, but I damn well never lose!!! ;)

Thanks for the info, and good luck with the repairs! How much had to be repaired after the hurricane?
