Q-TDPM Touchdown Circle Lighting

Our low-profile lighting system outlines the Touchdown/Positioning Marking (TD/PM) Circle and H of offshore helidecks with yellow and green lights. It consists of a concentric circle of at least 16 discrete lighting segments. The elements have a width of 3.9" (100mm). A single circle is positioned at the mean radius of the painted circle of the helideck.

The lighting segments provide coverage between 50% and 75% of the circumference as stated in CAP437, and are equidistantly placed with the gaps between them not less than 1.64' (0.5 m). The mechanical housing is powder-grip-coated yellow.

Operation

The industry standard is below .98" (25mm). This allows optional mounting plates to not interfere with the compliance to the CAP437 regulation.

The core of the Q-TDPM are the LEDs which are designed with special side-emitting technology requested by the TD/PM in accordance to CAP437. The LEDs used in the Q-TDPM system have a high lifetime of 75,000 hours.

The side emitting LEDs will provide an optimal beam in the lower angles in azimuth, in such a way that the Q-TDPM is visible from every gliding slope on the approach path.

Cable Ducting Assembly

The TD/PM Circle is superimposed on the yellow painted marking. It comprises a concentric circle of at least 16 discrete lighting segments. The elements have a width of 3.9" (100mm). A single circle is positioned at the mean radius of the painted circle of the helideck. The lighting segments are connected with each other by marine grade cables that are sealed in the Q-Cable Ducting System.

Operation

The Cable Ducting System is mounted on the preassembled cable ducting brackets that are included on every system or parts of the Q-TDPM System. The rubber material of the Q-Cable Ducting System provides resistance of load and impacts and maintains the safety of the cable and passengers.
