Highlands and Islands Airports Limited (HIAL) and the Prospect union are discussing a possible alternate method of delivery for planned changes to the Air Traffic Management Strategy (ATMS).
HIAL has proposed using a central hub in Inverness to control air traffic at the airport, along with those at Sumburgh, Dundee, Kirkwall and Stornoway.
Unmanned towers would be located at Sumburgh in Shetland, Dundee, Wick John O'Groats, Kirkwall in Orkney, and Stornoway and Benbecula in the Western Isles.
However, Prospect has said the move would result in the loss of around 50 jobs and make these airports less safe.
