Ryan Airfield[1] (ICAO: KRYNFAA LID: RYN), also known as Ryan Field,[2][3] is a city owned, public use airport located 10 nautical miles (12 mi, 19 km) southwest of the central business district of Tucson, a city in Pima County, Arizona, United States.[2] It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a reliever airport.[4] It is mostly used for general aviation but also serves a significant amount of law enforcement and military helicopter activity. Approximately 50% of Ryan's traffic is training-related.

Although most U.S. airports use the same three-letter ICAO identifier is KRYN.[7]

Ryan was built by the United States Army Air Forces in 1942 as a site for primary flight training. Military flight training at Ryan ceased in 1944 and the property was conveyed to the State of Arizona in 1948. Currently owned by the City of Tucson, Ryan is operated by the Tucson Airport Authority under an agreement which expires in 2054.

An air traffic control tower was constructed at Ryan in 1993. The airport was added to the Contract Tower Program in 1996. In September 2004 the tower staff completed the one millionth operation without an error. In May 2010, the tower staff achieved two million operations without an error.

Significant infrastructure improvements and major maintenance projects are accomplished continuously, as is private and commercial hangar construction.

Facilities and aircraft

Ryan Field covers an area of 1,754 acres (710 ha) at an elevation of 2,419 feet (737 m) above mean sea level. It has three runways with asphalt surfaces: 6R/24L is 5,503 by 75 feet (1,676 x 23 m); 6L/24R is 4,900 by 75 feet (1,494 x 23 m); 15/33 is 4,000 by 75 feet (1,219 x 23 m).[2]

Only runway 6R is serviced by an instrument approach. It allows pilots to land with ceilings as low as 250 feet above ground level. Runways 6L and 6R are the preferential runways, and they are used with tailwinds up to 10 knots.

For the 12-month period ending March 31, 2009, the airport had 159,806 aircraft operations, an average of 437 per day: 97% general aviation and 3% military. At that time there were 192 aircraft based at this airport: 91.7% single-engine, 5.7% multi-engine, 2.1% helicopter, and 1.6% helicopter.[2]
