Required Operational Capability (ROC) for a Portable Heliport Lighting Set (PHLS)
Abstract
In order to provide the unit commander with the greatest possible flexibility, the PHLS should consist of two components (an approach path indicator (API) and LZ marker lights) packaged as a set. The API will provide a tricolored glidepath to assist the pilot to a safe landing in a designated permissive LZ. The remotely controlled LZ markers will be used to mark the perimeter of the LZ and will have both an infrared (IR) and incandescent light capability. This would enable the markers to be used in conjunction with the API or separately to designate a non-permissive LZ. In the incandescent mode, the API and the LZ marker lights would be used to train pilots in night vertical assault operations and also would be used for missions flown into permissive LZ's. Pilots flying in a night vertical assault may use NVG's and employ terrain-following flight techniques. As elements of the flight cross the initial point (LP), the flight leader activates an IR LZ marker/identifier (a strobing marker light) using the aircraft's UHF radio transmitter. Once the LZ has been visually identified the pilot turn the marker off. It can then be turned back on by each successive wave, if required.
