United Kingdom Low Flying System

The United Kingdom Low Flying System (UKLFS) is the airspace across the United Kingdom in which low flying training is permitted. The system was established in 1979 and extends from ground level to 2000ft AGL. Flying is carried out from 0800 to 2300 during weekdays only.
