Airspace Advisory (Mildenhall): Temporary unmarked and unlit mast obstruction up to 800ft AMSL (100ft AGL) within Low Flying Area 1A and Night Rotary Region 1. Active 24/7 until July 22, 2026.
⊘⊘ OBSTRUCTION NAVIGATION WARNING // MILDENHALL MAST ⊘⊘
A temporary lower-airspace safety warning is active for this sector due to a newly logged, unlit physical obstacle intersecting low-altitude flight paths.
⊘ GEOGRAPHIC POSITION -- Located at coordinates 51°27'03"N, 001°42'02"W near Mildenhall, Wiltshire. The hazard sits directly within Low Flying Area 1A (LFA 1A) and Night Rotary Region 1. ⊘ VERTICAL HEIGHT -- The structural mast stands up to a physical height of 100ft AGL (Above Ground Level), reaching a maximum altitude ceiling of 800ft AMSL (Above Mean Sea Level). ⊘ HAZARD PROFILE -- Because the mast is officially registered as unmarked and unlit, it lacks mandatory strobe lighting or high-visibility visual markers. This introduces a significant physical collision risk to unmanned systems, especially during overcast conditions or twilight hours. ⊘ CONTEXT & TIMING -- The warning remains active continuously until July 22, 2026. This sector experiences routine low-level military exercises and crewed helicopter operations. ⊘ PILOT DIRECTIVES -- Remote drone operators must maintain a strict, uninterrupted visual line of sight (VLOS) with their craft. Maintain defensive vertical clearance when operating within this coordinate block and actively scan the surrounding sky for both the physical structure and low-flying crewed rotorcraft.
