Flight Restricted Zone
In the United Kingdom, flights of unmanned aircraft around aerodromes that are designated as ‘protected aerodromes’ are restricted. Unmanned aircraft of any size must not be flown within the Flight Restriction Zone (FRZ) of a protected aerodrome, without appropriate permission.
Flight Restriction ZoneFlight Restricted Zone (FRZ) Dimensions
The Flight Restricted Zone (FRZ) is designed to keep aircraft operating at the airport safe. The FRZ extends upwards to a height of 2,000 feet above the airfield and consists of two elements:
- The dimension of the airfield’s existing Aerodrome Traffic Zone (ATZ), which has a radius of two and a half nautical miles.
- A Runway Protected Zone (RPZ) which is a five kilometre by one kilometre zone starting from a point known as the ‘threshold’ which is located at both ends of the runway.
