Common use of Community Noise Clause in Contracts

Community Noise. Community Noise of the Vehicle will be based upon six Vehicle noise measurements from three points during FTOP operation. Two measurements will be taken from each of the three points and the highest noise level measured will be the score. Community Noise will be measured in dBA, slow scale. The first measuring point will be located sideways from the Vehicle's full power run-up/brake release point at the SMD (Sound Measurement Distance) for that Vehicle's flight-demonstrated RDC. The second measurement point will be at a point down the centerline of the runway at a distance of 50% greater than the Vehicle's RDC. The third measurement point will be that taken during a high speed level overflight using FTOP at 1125 MSL, 1000 feet above the measurement point. Measurements will be made at these three measurement points during the same takeoff roll, and two takeoff rolls will thus be required to obtain all six Vehicle Community Noise measurements. If a Vehicle's community noise measurement at the SMD appropriate to its flight-demonstrated RDC exceeds the CRS noise limit, then that Vehicle's RDC will be re-assigned to the next longer RDC at which the Vehicle can meet the CRS noise limit. Such re-assignment will cause that Vehicle's score in the PAV Runway Prize to default to the length of that longer RDC and will also cause its GTT, GTC and IMD, used to score the PAV CAFE Efficiency Prize, to become those of the longer RDC for which it qualifies (Appendix A). The longer RDC will also be used by the judges to help determine that Vehicle's score in the PAV Handling Prize.

Community Noise. Community Noise of the Vehicle will be based upon six four Vehicle noise measurements from three two points during FTOP full power operation. Two measurements will be taken from each of the three two points and the highest noise level measured will be the score. Community Noise will be measured in dBA, slow scale. dB as LAeq,(4sec.) The first measuring point will be located sideways from the Vehicle's full power run-up/brake release point at the SMD (Sound Measurement Distance) for that Vehicle's flight-demonstrated RDC. The second measurement point will be at a point down the centerline of the runway at a distance of 50% greater than the Vehicle's RDC. The third measurement point will be that taken during a high speed level overflight using FTOP at 1125 MSL, 1000 feet above the measurement point. Measurements will be made at these three both measurement points during the same takeoff roll, and therefore two takeoff rolls will thus be required to obtain all six Vehicle Community Noise measurementsrequired. If a Vehicle's community noise measurement at the SMD appropriate to its flight-demonstrated RDC exceeds the CRS noise limit, then that Vehicle's RDC will be re-assigned to the next longer RDC at which the Vehicle can meet the CRS noise limit. Such re-assignment will cause that Vehicle's score in the PAV Runway Prize to default to the length of that longer RDC and will also cause its GTT, GTC and IMD, used to score the PAV CAFE Efficiency Prize, to become those of the longer RDC for which it qualifies (Appendix A). The longer RDC will also be used by the judges to help determine that Vehicle's score in the PAV Handling Prize.
