The Air Navigation (Restriction of Flying) (Chelmsford) (Emergency) (No. 2) Regulations 2026
Established a temporary restricted flight zone over Chelmsford at altitudes below 1,000 feet to facilitate emergency response efforts.
These Regulations prohibit the flight of all aircraft below 1,000 feet above mean sea level within a specified two-nautical-mile radius of Chelmsford, Essex.
The Secretary of State issued this order in response to an emergency, exempting only those aircraft flying under directions provided by the Essex County Fire and Rescue Service. The regulations have immediate effect and include the revocation of a previous emergency order for the same area.
Arguments For
The Secretary of State asserts that these restrictions are necessary for reasons affecting the public interest due to an emergency that has arisen in the area.
The document states that the restrictions are intended to be of temporary duration.
The explanatory note indicates that the regulations will be revoked once the emergency has passed.
Arguments Against
Aviation operators may face operational disruption or increased costs due to the sudden and immediate implementation of the flight ban.
The document does not specify the nature of the emergency, requiring pilots to rely on external updates for situational awareness.
Legal scholars might note that the immediate commencement gives affected parties no lead time to adjust flight plans established prior to the order.
Citation and commencement
- These Regulations may be cited as the Air Navigation (Restriction of Flying) (Chelmsford) (Emergency) (No. 2) Regulations 2026 and they come into force with immediate effect.
This section provides the official name for the regulations and states that they become legally enforceable immediately upon being made.
This removes the standard waiting period often associated with new legislation to address the emergency situation.
Restricted airspace
No aircraft is to fly below 1,000 feet above mean sea level over the area specified in Column 1 of the Schedule, being an area bounded by a circle of the radius specified in Column 2 and centred on the position specified in Column 3.
These Regulations do not apply to any aircraft flying in accordance with directions given by the Essex County Fire and Rescue Service.
These provisions establish a circular restricted zone where aircraft are barred from flying below 1,000 feet.
The restriction applies to all aircraft except those operating under the specific instructions of the Essex County Fire and Rescue Service, effectively granting them control over the lower airspace in the designated area.
Revocation of Regulations
- The Air Navigation (Restriction of Flying) (Chelmsford) (Emergency) Regulations 2026( b ) are revoked.
This section cancels the previous version of these emergency regulations (S.I. 2026/879).
By doing so, it ensures that this new order replaces the earlier rules rather than operating concurrently with them.
