Drone TDAs ‘out of control’ with new Scottish ACP 5th May 2021 10:24 Europe/London A huge area of airspace 25nm south of Prestwick, Scotland will be blocked off if a new Temporary Danger Area (TDA) for drone operations goes ahead. The TDA is 160 square miles, from the surface to 3,700ft around Newton Stewart, Dumfries. It is surrounded by the D402, D403 and D405 existing Danger Areas and is thus often used by transitting VFR traffic looking for a low-level north-south route. The period of operation is September-October this year. An unnamed mineral exploration company has rights to areas north and east of Newton Stewart and wants to make a magnetic geophysical survey of their mineral concession area.
