    The quieter the aircraft the smaller the QC value. Aircraft are classified separately for landing and take-off. Take-off quota count values are based on the average of the certificated flyover and sideline noise levels at maximum take-off weight, with 1.75 EPNdB added for Chapter 2 aircraft. Landing quota count values are based on the ...
