AIRSPACE SAFETY ADVISORY // EGLB BROOKLANDS An increased operational risk environment has been identified for uncrewed aerial systems operating within this sector due to the proximity of localized aviation activities. • HAZARD CLASSIFICATION: Area of increased low-altitude traffic density. • TRAFFIC PROFILE: Heightened probability of encountering crewed aerial vehicles, historic aircraft, and low-flying rotary assets maneuvering in the lower airspace. • VERTICAL EXPOSURE: Continuous low-level flight operations occurring from the surface upward. • SAFETY REQUIREMENTS: Remote pilots must maintain an uninterrupted visual line of sight (VLOS) with their aircraft at all times. Actively monitor the surrounding horizon for acoustic or visual signs of approaching traffic. Yield right-of-way immediately, unconditionally, and safely to all crewed aircraft.

STATUTORY AIRSPACE & OBSTRUCTION PROTOCOL: WEST DRAYTON (EGLL FRZ)
======================================================================
REGULATORY ENFORCEMENT MANDATE // PERMANENT AIRFIELD OBSTRUCTION
This geographical sector (Falling Lane, West Drayton) is subject to strict statutory flight restrictions under the UK Air Navigation Order due to its positioning inside the active London Heathrow Airport (EGLL) Flight Restriction Zone (FRZ).
[1] STATUTORY PROHIBITED ZONE: All uncrewed aerial systems (UAS/Drones) are legally barred from launching, operating, or landing within this perimeter from the surface level upward without prior official clearance.
[2] AIR TRAFFIC CONTROL CONTROL: Remote pilots are strictly required to submit a Non-Standard Flight (NSF) application via the NATS coordination portal and obtain explicit Air Traffic Control (ATC) approval before flight.
[3] PHYSICAL OBSTRUCTION HAZARD: If flight clearance is granted, pilots must navigate with extreme caution regarding a permanent industrial tower crane established at coordinates 51°30'45"N, 000°27'29"W (Falling Lane).
- Physical Reach: 214ft AGL (Above Ground Level) / 325ft AMSL (Above Mean Sea Level).
- Visual Markings: Fitted with active red safety lighting (non-operational during Low Visibility Procedures).
- Separation: Drone operators must maintain strict separation and a flawless visual line of sight (VLOS) at all times.
AERONAUTICAL RECORDING INDEX: Codified under UK CAA NOTAM ID EGGN/A1172/26 (AIP EGLL AD 2.10 Reference / Obstacle ID: 20260319177).

AIRSPACE OBSTRUCTION: HEATHROW (SOUTHALL) A permanent aerodrome obstruction entry has been registered for the lower-altitude flight corridors near London Heathrow Airport. Remote pilots must adjust local site risk assessments to maintain required clearances. LOCATION DETAILS—Merrick Place, Merrick Road, Southall, London (UB2 4AU) at coordinates 51°30'20"N, 000°22'38"W. ELEVATION VALUES—The tower structure reaches 431 ft AGL (Above Ground Level) and 537 ft AMSL (Above Mean Sea Level). Lighting Profile—Equipped with operational steady red safety lighting for night and low-visibility recognition. CONTEXT & RUNWAY RISK—Positioned within the Heathrow (EGLL) airfield's circling area. Due to direct proximity to intensive international commercial runway vectors, drone operators must maintain a defensive flight posture. COMPLIANCE DIRECTIVE—Remote operators are strictly required to preserve an unbroken visual line of sight, remain entirely clear of this structural vertical column, and yield unconditional right-of-way to all approaching or departing manned aircraft. DATA CLASSIFICATION: Sourced via UK CAA NOTAM ID EGGN/A2115/24 (AIP EGLL AD 2.10 / Obstacle ID: 2024021538).

// SYSTEM ALERT: AERODROME TRAFFIC ZONE (ATZ) PROXIMITY // TARGET LOCATION: EGLD DENHAM AIRPORT // STATUS: This sector is officially designated as an Area of Increased Risk due to active runway and helipad operations. // HAZARD METRICS: Sustained, high-volume manned aviation traffic, including fixed-wing arrivals/departures and rotary-wing movements from the surface up. // UAS OPERATIONAL MANDATE: Unmanned aerial vehicle (UAV) pilots must strictly respect aerodrome perimeter restrictions. Constant visual line of sight (VLOS) is mandatory. Manned aviation holds absolute, unquestionable right-of-way. Do not launch if you cannot guarantee total separation from airport approach and departure vectors.

[AERONAUTICAL FIELD BRIEF: NEW MODEL FARM HELIPORT] This text serves as an active risk brief for unmanned aircraft pilots operating within this specific geographic sector. I. SITUATIONAL ANALYSIS: This zone contains the New Model Farm helicopter landing facility, establishing an environment with frequent low-altitude rotary-wing aircraft traffic. II. ALTITUDE PROFILE: The operational hazard exists directly from the surface level extending upward. III. THREAT DESCRIPTION: Heightened probability of encountering low-flying manned helicopters during takeoff, approach, and landing patterns. IV. OPERATOR DUTIES: Remote pilots must maintain complete situational awareness, conduct continuous visual and auditory scanning of the horizon, and yield right-of-way unconditionally to all approaching or departing aircraft.
