San Lorenzo Citizens Fighting Airport Noise



Daily Average Aircraft Operations
Hayward Executive Airport



An operation is defined as either one takeoff or one landing. Thus, if an aircraft takes off and lands at the airport, that counts as two operations. The daily averages reported in the tables here represent a mixture of departures and landings, and it is assumed (in the absence of an actual count) that half the operations on any one day are departures and half are landings. Since departures (take off) but not landings produce loud noise, the number of potentially noisy operations is one-half of each day's average.

The daily averages are based on daily counts of departures and landings by the FAA controllers in the airport tower. Since the tower is closed from 9 p.m. to 7 a.m., the averages do not include operations in this nighttime period. However, because the number of nighttime operations each day is quite small, their absence in the daily totals and averages does not affect the pattern of daily averages. Note, too, that since operations are counted for only 14 hours each day, the hourly average operations are given by dividing the daily average by 14, not 24.

The data show that, while operations are greater on the weekends than on weekdays, the difference on average is not so great that one can say that weekend operations are considerably more annoying (noisier) than weekdays. In fact, the greatest variation in daily operations is day to day, and this variation can be extreme. One day may have 350 departures and landings, while the next day only a dozen.

Until 2013 there was a steady, continuing decline in air traffic (number of operations) at Hayward over several years. In 2013 traffic increased about 20 percent over 2012, and it has continued to increase through 2015. (See annual total operations.)
