Due to the location of the YGC airfield over Sutton Bank and the A170 road, coupled with the crowded airspace in the Vale of York, there have been some notable incidents at Sutton Bank or in the vicinity. It is worth noting that the airspace around the airfield is designated as Class-G, which means that the principle method of preventing accidents (moreover mid-air collisions) is a see and avoid system. Also, microlights, gyrocopters and gliders have different airworthiness codes and different licensing standards for their pilots in comparison to those of heavier commercial, military and passenger carrying aircraft.
