Hello,

When pursuing IEQ/Acoustic Performance/Opt2 credit? We're trying to determine what exterior noise classification we are per FGI table A1.2a, but we're wondering if all the criteria in the specified Noise Exposure Category have to be satisfied (i.e., if we have Ldn <65 dB, but are within 1000 ft of a flight path, does that automatically put us in Category D)?
