Activity levels at airports are measured by aircraft operations. An operation is defined by the FAA as a takeoff or a landing. So, a “touch and go” conducted by a training aircraft counts as two operations. In 2021, RMMA experienced 201,423 aircraft operations. That’s, on average, a takeoff or landing approximately every three minutes. However, the amount of operations varies significantly by season and time of day. The highest annual operations at RMMA occurred in 1977, with more than 248,000 aircraft operations.
