Riverside Municipal Airport — Riverside, United States

RAL denotes Riverside Municipal Airport, a general aviation facility in Riverside, California, in the Inland Empire region east of Los Angeles. Unlike commercial airports, RAL primarily serves private pilots, flight training schools, corporate aircraft, and law enforcement or medical helicopter operations rather than scheduled passenger airlines. The airport has two runways and is city-owned, functioning as an important reliever airport that keeps general aviation traffic away from busier regional airports like Ontario International. Riverside's airport has a long aviation history dating back decades and continues to support flight instruction, given Southern California's favorable year-round flying weather.
