Aubrey Gladstone is an experienced business administrator and project manager who has served as president of Gladstone Consulting for more than two decades. He has been a commercial pilot even longer, flying with National Jet Corp. since 1980. Over the course of his aviation career, Aubrey Gladstone has flown a wide range of aircraft, including the Cessna Citation SP series.
Part of the 500 Citation series, the Citation I/SP was one of the first single-pilot, owner/flown jet aircraft. It shares the same turbo-fan-powered engine as the original Citation I, which featured a cockpit designed for two pilots. Both of these business jet models entered into production in 1977.
Because it was configured for a single pilot, the Citation I/SP allowed room for an extra passenger on the flight deck. The cabin is designed to seat up to six passengers and features both a full-width lavatory and a small galley/refreshment center.
Cessna ceased production on both the Citation I and the Citation I/SP in 1985. The company ultimately replaced the Citation line with the CitationJet several years later.
