62 -- EXPEDITIONARY AND NIGHT VISION DEVICE- COMPATIBLE AIRFIELD LIGHTING AND LANDING AID SOL N68335-97-RFI-711 DUE 072397 POC Amy Hayward Contract Specialist, 213AH (732) 323-2921. Request information from companies regarding the manufacture of an expeditionary and night vision device compatible airfield lighting and landing aid. The complete system must be capable of supporting a bi-directional runway and associated taxiways. Runway edge lights shall produce omni-directional runway and associated taxiways. Runway edge lights shall produce omni-directional white light with three switchable intensity levels. The lamp shall have an output of 50 candelas when set on "high" intensity, and two levels of Night Vision Device compatible output when switched to the "medium" and "low" intensities. Night Vision Device compatibility shall not be achieved via changing the lens. Runway edge lights shall be powered by rechargeable batteries, having a minimum usable charge of eight hours and a maximum recharge time of 16 hours. Runway edge lights shall also have provisions for operation from an external AC power source. Taxiway edge, obstruction, and runway threshold/terminus lights shall all bederived from the same fixture as the runway edge light, with the same pre-set intensity levels. Interchangeable lenses of blue, red, and red/green, respectfully, shall be used to achieve the required function. Runway approach lights shall produce unidirectional white light through 20 degrees of azimuth with three levels of intensity: 100, 1000, and 5000 candelas. Runway approach lights may be solely AC-powered to accomodate these intensities. If battery operated, runway approach lights shall use rechargeable batteries, having a minimum usable charge of eight hours and a maximum recharge time of 16 hours. Glideslope indicators shall be derivatives of the Precision Approach Path Indicator (PAPI) system. A "2-Box Abbreviated" PAPI shall be provided for day- and night-time approaches made without the assistance of Night Vision Devices (NVD). This "tactical" PAPI shall have the following three levels of light intensity: 500, 5000, and 50,000 candelas. The "tactical" PAPI may be solely AC-powered to accomodate these intensities. If battery operated, the "tactical" PAPI shall use rechargeable batteries, having a minimum usable charge of eight hours and a maximum recharge time of 16 hours. The NVD-compatible PAPI system shall utilize a "4-box" arrangement with steady and flashing infra-red emissions to mimic the white and red, respectfully, visual presentation of a typical PAPI system. The NVD-compatible PAPI may have one or more intensity level(s). The NVD-compatible PAPI shall be powered by rechargeable batteries, having a minimum usable charge of eight hours and a maximum recharge time of 16 hours. Both PAPI systems shall be capable of providing glideslope angles of 2 to 8 degrees, in one-half degree increments. Glideslope angle must be capable of being changed by a single operator with no tools. Each lighting component shall have provisions to adjust intensity (where applicable) and be turned on and off via both integral manual switches and wireless remote control from a hand-held controlling unit. When operated in the manually switched mode, wireless remote functions shall be disabled and vice versa. The controlling unit shall have individual switches for each function (e.g. high intensity, low intensity, off). Each component shall be capable of being controlled and operated by personnel wearing full Nuclear Biological and Chemical (NBC) or arctic clothing. If AC power is required for operating the runway approach lights and/or "tactical" PAPI, two sources shall be provided for each runway approach; one as a primary source, the other as an identical back-up. Any cables required for connection to the power sources shall be included with the system. System must provide battery recharging equipment in sufficient quantity to simultaneously recharge all components having rechargeable batteries. A power source large enough to supply power to all the rechargers is not required as part of this system. All of the system components shall be packaged in no more than five wheeled trailers, each capable of being towed by Marine Corps vehicles of the one and one-half ton weight class and above; certified for external transport by all Marine Corps helicopter models; internally transportable by the CH-53E aircraft; and deployable aboard all types of sealift and inter/intra-theater Air Mobility Command aircraft. The entire system shall be capable of being transported inside a single C-130 aircraft. Each trailer shall have an integral pedometer to aid in the positioning of lights. Respondents to this Request for Information (RFI) are instructed to submit information about subject system. Any information provided may or may not be included in a formal solicitation. The Government will neither pay for any information received in response to this RFI nor will the Government compensate any respondent for any costs incurred in developing the information provided. There is no solicitation package. This is a Request for Information Only. (0190)
