Rialto Municipal Airport , originally called Miro Field, is a general aviation airport located three miles (5 km) northwest of the central business district (CBD) of the city of Rialto, in San Bernardino County, California, USA.
It is used exclusively by privately operated and chartered aircraft; no commercial airlines fly into this airport. The airport is located approximately eleven nautical miles northeast of Ontario International Airport and nine nautical miles west of San Bernardino International Airport. The airport does not have a control tower and, on average, handles 82 operations a day.
An FBO with a flight school and a separate helicopter flight school operate at the airport. There are several aviation related businesses on site. There is an air ambulance business in the southeast part of the airport.
Despite its above average size compared to other nearby airfields (Upland Cable, Corona Municipal, El Monte Municipal, Redlands Municipal and Hemet-Ryan Airport), Rialto is a relatively quiet and somewhat uneventful airport. This has led the city of Rialto to approve the closing of the airport by 2009/2010 for redevelopment of the property for other purposes driven by local real estate developers.
In 1978 Art Scholl Aviation, founded by Art Scholl, relocated to Rialto Airport from nearby Flabob Airport in Riverside, California.
Since 1984 the City of Rialto has accepted more than USD$15 million in federal aid for airport improvement and land purchases.
