16 -- AIRCRAFT COMPONENTS AND ACCESSORIES POC Rilla Marritt, OC-ALC/LAD, 405-736-5370 Potential Sources Sought. This is not a request for proposal. Applicable to: KC-135. The Air Force is adding an Altitude Alerter to the KC-135 aircraft. Candidates must be Non Developmental Items (NDI) capable of utilizing existing aircraft altitude signals. System Compliance: (1) FAA approved, TSP C88a. (2) C/KC-135 operational environment, testing per DO-160. System Functions: Provide appropriate audio and visual warnings upon approaching a selected altitude and deviation from an envelope surrounding an assigned altitude (selection in 100 ft increments acceptable). Digital display of altitude from -1000 to +55000 ft. in 100 ft increments. Accepts ARINC 429 data (altitude) or Grey Code (both inputs desired). Audio Tone internal to the alerter is acceptable (desire for external signal to crew headsets). Audio Tone and visual signal time durations can be pre-set (desire to be user-defined). Physical Characteristics. The alerter must be small enough to be placed on the -135 glareshield. (1) Size should not exceed 1.6 inches (H), 3.5 inches (W), and 6 inches (L). Weight shall not exceed 1.5 lbs. A standard rectangular 1/2 ATI configuration preferred. (2) Viewability angle plus or minus 60 degrees from centerline horizontally and plus or minus 30 degrees from centerline vertically (up and down). (3) Single Control for Altitude selection through adjustable knob/dial or push button. (4) Power requirements of 115VAC/400Hz, or 28VDC. Maximum of 1 amp or 30 watts. Additional information on the C/KC-135 operational environment: temperature, pressure, humidity, vibration, shock, crash safety, and explosive environment, can be obtained by contacting OC-ALC/LCRE, Capt Dan Witt or Lt Darren DeRoos at 405-736-5843. The approximate issue/response date will be 15 Nov 97. No telephone requests. Only written or faxed requests received directly from the requestor are acceptable.
