Monthly Runway Use Report

The five runways at Midway are utilized at different times primarily depending upon the prevailing wind conditions on the airfield, as well as any runway maintenance. Aircraft performance requirements make it necessary for aircraft to depart and land into the wind for safety reasons.

The Runway Use Report presents the average number of daily operations on each runway, the percentage of use for each runway and a 12-month average. The percentage of use for each runway is shown graphically for departures and arrivals. This data is for all hours of the day and night and for all aircraft types during the specified quarter.

Annual Noise Report

The Aircraft Noise Report summarizes noise measurements from each of the 12 noise monitors located around the Airport. The data presented summarizes the Day-Night Average Sound Levels (DNL). DNL is a 24-hour time-averaged sound exposure level with a 10 decibel (dB) nighttime (10 p.m. to 7 a.m.) weighting to account for the lower background noise levels during the nighttime hours.

The data displays the measured aircraft DNL for each quarter and its comparison to the same quarter of the previous year, and it compares the current quarter to the 12-month average. The aircraft noise report identifies noise from the existing aircraft operations at Midway International Airport.
