About the Cessna 1SP
The Cessna 501 Citation I/SP is the single-pilot certified version of the original Citation I. It was specifically engineered to allow owner-operators to step up from high-performance twins and turboprops into the jet world without the requirement of a second-in-command. While it shares the ‘Slowtation’ reputation, it offers unparalleled simplicity and safety for solo jet operations.
Key Features for GA Buyers
- Single-Pilot Certification: Unlike the standard Model 500, the 501 is factory-certified for single-pilot flight, significantly reducing operational costs and scheduling complexity for owner-operators.
- Simplified Systems: Features straight wings and simple mechanical systems that are more reminiscent of a King Air than a complex swept-wing jet, leading to very docile stall characteristics.
- Runway Flexibility: The 501 includes the wing extensions and thrust reversers that became standard on later Citation Is, allowing for operation on runways as short as 3,000–3,500 ft.
- No Structural Life Limit: Like its sibling, the 501 airframe has no fatigue life limit, making it a sustainable long-term asset if corrosion is kept at bay.
Trade-offs
- Legacy Avionics: Many 501s still carry legacy ‘steam gauges’ and early autopilot systems; modernizing the panel (e.g., Garmin G600/G700) is a common but significant six-figure investment.
- Fuel Efficiency: The JT15D-1A engines are thirsty by modern standards, particularly at lower altitudes where the aircraft is often forced to fly due to RVSM constraints on non-upgraded airframes.
- Range with Full Seats: With a maximum payload of 2,100 lbs, carrying 5–6 passengers and their bags will significantly trade off fuel, often limiting range to roughly 500–600 nm.
