AVIATION SAFETY NOTIFICATION: SOUTH MIMMS REGION

Remote drone operators are advised to observe special safety precautions within this sector due to overlapping uncrewed aviation activities.

- HAZARD CLASSIFICATION: Heavy/Large Model Aircraft Operations
- GEOGRAPHIC BOUNDARY: 1 Nautical Mile (1NM) radius around central coordinates 51°43'01"N, 000°15'44"W (South Mimms zone).
- VERTICAL COLUMN: Extending from surface ground level up to 2,000 feet AMSL.
- EFFECTIVE SCHEDULE: Active daily from Sunrise (SR) to Sunset (SS), running from May 22, 2026, through to August 17, 2026.
- MANDATORY PROTOCOL: Due to the high-altitude capabilities of large model aircraft in this specific perimeter, drone pilots must execute rigorous visual scanning, preserve a strict line of sight, and instantly yield right-of-way.

REGULATORY REF: Published under UK CAA Airspace Navigation Warning NOTAM ID EGGN/H2416/26 (File: AR-2026-4025/01).
