The frustrating thing I found last year flying from Carrapateena over to Leigh Ck in the dark was that the PAALC does not give a confirmation response upon activation. Common problem with the older units and something I asked to be raised st the MOS139 review. The only clue I had that the lights were activated before my arrival was the white beacon which I could see from about 30nm.
gives weight to the argument of having a responsible person on the ground to manually turn the lights on.
