What is the circular pavement at the end of a runway called?
It is called the turn pad. This area(pad) is usually located at the thresholds of the runway, where no taxiway exists, so in order for the pilots to make a full-length takeoff, (or taxi to the Apron) they have to backtrack amd make a U-turn on there. Gernerally speaking, these pads exist on small airports. You can see the turn pads at the 2 thresholds of the runway. Skiathos Airport, Greece
