Details Q-TD/PM System

Circle & H Lighting for helideck - TouchDown Positioning Marketing - (TD/PM) and Lit Heliport Identification Marking (H) 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 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 0.5 m. The mechanical housing is powder-grip-coated yellow.


The lighting segments are connected by special explosion proof cable connectors. 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 SS316material of the Q-Cable Ducting System provides resistance of load and impacts and maintains the safety of the cable and passengers.

Based on the CAP437 regulation the industry standard height is a maximum of 25 millimeters. The height of the Q-TDPM units is only 23 millimeters. The core of the Q-TDPM are the LEDs. The LEDs are designed with special side-emitting technology in accordance to CAP437 and 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.
