History
- 1968Cessna announces the Fanjet 500, its first business jet.
- 1969The prototype makes its first flight on September 15, 1969.
- 1971The FAA certifies the Model 500 Citation on September 9, 1971, under FAR Part 25 (transport category). Deliveries begin in 1972.
- 1976The improved Citation I arrives: a longer wing (47 ft 1 in span), JT15D-1A engines that give more thrust above 28,000 ft, and a maximum altitude of 41,000 ft.
- 1977The Model 501 Citation I/SP is introduced, certified under FAR Part 23 so that it can be flown by a single pilot when properly equipped.
- 1985Production ends after about 690 airplanes (Models 500 and 501).

Figures from the Citation/Citation I pilot training manual. Some early serial numbers differ (for example, airplanes UN 0001–0213 and 0234 not modified by SB 21-9 are limited to 35,000 ft with an 8.0 psi differential). Always use the Airplane Flight Manual of the specific airplane.
A simple, robust jet
The Citation was designed for simplicity and easy maintenance. It is a pressurized low-wing jet with two engines mounted on the rear fuselage, built with a fail-safe structure. Its low takeoff and landing speeds let it operate from small airports.
- Electrical: two engine-driven starter-generators supply the DC system; two static inverters provide AC power.
- Fuel: two identical, independent halves, one wing tank per engine, with crossfeed.
- Ice protection: pneumatic boots on the wing and tail leading edges, an electrically heated inboard wing section, and engine bleed air for the engine inlets and the windshield.
- Hydraulics: engine-driven pumps for the landing gear, speedbrakes and optional thrust reversers, with pneumatic backup for gear extension and braking.
- Flight controls: conventional cable-operated controls, with mechanical nosewheel steering through the rudder pedals.

Why the Citation 500 needs two pilots
The Model 500 is certified under FAR Part 25 with a minimum crew of two pilots. The pilot in command needs a Citation type rating (FAR 61.58), and the copilot must meet FAR 61.55, the second-in-command qualification rule. For years, some operators flew these jets alone under FAA single-pilot exemptions. On September 29, 2026, the FAA ended those exemptions, so the Model 500 and the other two-pilot Citations of the 500 series now always need a qualified second pilot.
One type rating, many Citations
CE-500 is the FAA type designator for the whole Citation 500 family. The same CE-500 rating covers the Model 500 (Citation and Citation I), 501 (Citation I/SP), 550 (Citation II and Bravo), 551 (Citation II/SP), S550 (Citation S/II), 552 (T-47A) and 560 (Citation V, Ultra, Encore and Encore+). The rating is the same for all of them; moving between models may require differences training, as described in the FAA Flight Standardization Board report for the CE-500.
Fly the Citation I with us
We train in two Citation I jets, N31LW and N74LL, at North Perry Airport (KHWO) in Florida: online ground school on the real Citation systems, then flight training in the actual airplane under FAR 61.55.
Frequently asked questions
CE-500 is the FAA type designator for the Cessna Citation 500 family. It is the code that appears on a pilot certificate for a type rating in these airplanes, from the original Citation and Citation I to the Citation II, Bravo, V, Ultra and Encore.
No. The Model 500 is certified under FAR Part 25 with a minimum crew of two pilots. Only the Model 501 Citation I/SP, certified under FAR Part 23, can be flown by one pilot when it has the required equipment and the pilot meets the single-pilot requirements.
About 690 Model 500 and 501 airplanes were built between 1971 and 1985. Many are still flying, including the two Citation I jets we use for training.
Yes. We offer the CE-500 SIC type rating under FAR 61.55, with online ground school and flight training in a real Citation I in Florida. Your first lesson is free.
