Did my Falklands R&R on Pebble Island, FIGAS uplift from MPA determined by the time of low tide in Elephant Bay as the beach was the runway. Hotel owner would determine which part of the beach gave the best surface and wind direction and radio info to the pilot after he had "buzzed" his arrival. Someone in FIG had determined the Pebble airstrip had not recovered from the pounding it had received in '82 (this was '89!) and was unsuitable for the Islander.
