- THIS IS NOT A SOLICITATION. This Request for Information (RFI) is for information and planning purposes only and does not constitute a Request for Proposal. It shall not be construed as a commitment by the Government to award a contract as a result of this request for information. The Naval Air Warfare Center Aircraft Division Lakehurst is seeking information on portable runway lighting systems in support of the USMC Expeditionary Airfield (EAF) mission. Recent advances in off-the-shelf battery, remote control and light emitting diode (LED) technologies have shown the potential to replace or augment existing systems in the EAF inventory. An immediate solution to desired capabilities stated herein is not required at this time. The intent of this RFI is to gain awareness of the different technical approaches being pursued by industry to advance the market of airfield lighting. The capabilities and technical characteristics presented in this synopsis shall be considered as guidance only, do not represent a final system specification, and may be subject to change at a later date. The EAF concept supports a myriad of airfield lighting configurations, ranging in size and complexity from single-aircraft vertical take-off and landing (VTOL) sites, to short runways for tactical aircraft, to extended runways for heavy cargo lift. Therefore, it would be impractical to define such complete, overarching capability in a single, inflexible performance specification. For the purpose of this RFI, the term “modified medium intensity, visual flight rules” will be used as a generic performance description for a system capable of supporting a single, 4000-ft long runway. The demonstrated or implied potential to improve upon the stated capabilities in order to increase the application and/or capability of the system, or its components, will also be considered. The unique operating scenario of the EAF concept places many equipment configuration specifications outside the scope of US Navy (NAVAIR 51-50AAA-2), Unified Facilities Criteria (UFC), Federal Aviation Administration (FAA), International Civil Aviation Organization (ICAO) and North Atlantic Treaty Organization (NATO) requirements. Although verbatim adherence to such published specifications would therefore be impractical, individual technical characteristics previously established by these agencies have served as the basis for a number of the performance criterion stated in this synopsis. Desired System Capability 1. System shall be capable of supporting both Night Vision Device (NVD) -aided and un-aided flight operations through the use of visual spectrum and infrared spectrum light sources. 2. The system shall be capable of providing adequate visual cues to allow acquisition of the airfield at a minimum straight-on approach distance of 3 nautical miles. This shall apply to both NVD-aided and un-aided flight operations. 3. All system components shall be stored aboard one, single-axle towed trailer. Trailer chassis shall be an approved variant of the Light Tactical Trailer, Heavy Chassis (LTT-HC); to include the Flatdeck (LTT-F), Flatdeck Extended (LTT-FE) and Marine Corps Chassis (LTT-MCC). Total system weight, including trailer, shall not exceed 4200 pounds. 4. The system shall, at a minimum, contain of the following airfield lighting components: 16 Runway Edge Lights 2 Runway End Identifier Lights 8 Runway Threshold Lights 1 Precision Approach Path Indicator (PAPI) system 5. All airfield lighting components shall utilize light emitting diodes (LED) or other solid state lighting devices for their light source. 6. All airfield lighting components shall be powered by rechargeable batteries, and include provisions for hard-wiring to a prime power source. Batteries shall be capable of maintaining the maximum power output of each fixture for a minimum of 16 hours, continuous, even when the battery capacity has been degraded to 75% of its as-manufactured capacity. All fixtures shall be capable of being fully recharged (within 95% of capacity) in less than 8 hours. The necessary battery charging equipment, sufficient to simultaneously recharge all the airfield lighting components provided with the system, shall be integral to the system and/or individual components. 7. On-board battery charging equipment shall be capable of operating from all commonly found voltages worldwide. 8. The system shall include one (1) DOD-approved 3kW diesel-fueled generator (model number MEP-831A) for the purpose of battery recharging, short-term hard-wired operation, and the operation of other ancillary equipment. 9. The method for providing hard-wired power distribution, other than the interface to each individual fixture, does not need to be defined in detail at this time. 10. Each airfield lighting component shall posses the means to be manually switched on/off and through all intensity and output settings. Additionally, each lighting fixture shall be capable of wireless control of all functions through a dedicated remote control unit operating within the appropriate ISM band. 11. All airfield lighting fixtures shall exhibit ingress protection to a level of IP67 or NEMA 6. Although the system is intended to be portable and capable of rapid installation, all runway lighting components shall be expected to survive an installed duration of no less than 12 months. 12. All airfield lighting fixtures shall possess the ability to recharge their battery when both attached or detached from the fixture. Removing the battery (or batteries) from a fixture shall not require any tools. 13. All airfield lighting fixtures shall be capable of being fitted to an individual mounting base. Mounting bases shall be capable of being secured to surfaces including, but not limited to: routine/hard soil, asphalt, rock, coral, concrete, and various types of airfield surfacing materials (matting). Attaching hardware for securing the fixture to such surfaces may be determined and sourced separately by NAVAIR Lakehurst. Mounting base shall possess a means to positively lock the light to the base while retaining frangibility of the fixture. Mounting bases shall be retrievable, require no scheduled maintenance and will be considered “consumable” items. Desired Performance of Individual Components Runway Edge Light 1.
