CAP 437 Prohibited Landing Marker Flag – 4m x 4m Helideck Closure Signal
The CAP 437 Prohibited Landing Marker (4m x 4m) is a fully compliant offshore helideck safety flag designed to clearly indicate “Landing Prohibited” status during maintenance, inspections, or emergency deck closures.
Manufactured in accordance with UK CAA CAP 437 and CASA CAAP 92-4(0) requirements, this helideck marker provides a mandatory high-visibility signal by completely obscuring the helideck “H” marking, ensuring clear communication to approaching aircraft.
Constructed from heavy-duty, UV-stabilised PVC rubberised vinyl, the marker is engineered for harsh offshore and marine environments. A reinforced 50mm welded hem combined with 20 SP4 spur-tooth eyelets delivers superior strength and durability in extreme weather conditions.
