Cessna Citation Series

Light business jet · Cessna 550 Citation II

Aircraft overview

Citation is a family of Cessna business jets, beginning with the straight-wing, turbofan-powered Model 500. The Citation II developed that concept into a larger pressurised aircraft, with a stretched cabin, larger wings and more powerful engines.

The Model 550 Citation II received FAA approval on 24 March 1978. Citation I, S/II, Bravo and V are separate developments, with different engines, weight limits and equipment.

Role guidance · v0.8.16.0

Air Defender v0.8.16.0 lists the Cessna Citation Series as Business Aviation. Its general catalogue record spans a family; it does not identify a particular Citation model or engine installation.

Compare the Learjet 35 and use Aircraft Data with flight-plan information. The real Citation II figures here are separate from the game’s general reference values.

In depth

From Citation to Citation II

The Citation II lengthened the original Citation fuselage by 1.14 m. Larger wings, increased fuel capacity and more powerful JT15D-4 engines accompanied the cabin stretch.

The S550 Citation S/II superseded it in production in 1984, before Citation II production resumed in 1987 from serial 550-0550. Later production break points changed the loading limits.

JT15D-4 installation

Two JT15D-4 turbofans power the Citation II. Each has a five-minute take-off rating of 2,500 lbf under standard sea-level conditions and a maximum-continuous rating of 2,375 lbf. These ratings belong to the II, separately from the Bravo’s PW530A installation.

Fuel and loading configurations

Each wing tank holds 376 US gallons, of which 371 are usable. The two-tank total is 752 gallons, with 742 usable.

An early Citation II with the baseline weight limits has a 13,300 lb take-off limit and a 12,700 lb landing limit. Its baseline zero-fuel limit is 9,500 lb. An approved modification permits 11,000 lb zero-fuel weight with a reduced operating-speed limit; 11,000 lb became standard from serial 550-0550.

Cabin arrangements

The Citation II requires two pilots. Eligible aircraft with the applicable cabin modification can carry up to 13 people in total, including the pilots. That is an approved maximum for the specified configuration, rather than a standard 11-passenger business interior.

Variants

500 Citation / Citation I

How to read aircraft specifications
Turbofan

A gas-turbine engine that also drives a fan. Some fan air bypasses the engine core; that airflow and the core exhaust contribute thrust.

Feet / ft

A unit of length used here for aircraft height. Read the display’s scale: a trackblock height of 350 means 35,000 feet, not 350 feet.

Related guide: trackblock
Flight plan

Information about an intended flight, such as its route and destination. Compare that plan with what the aircraft is actually doing.

Service ceiling

The stated height an aircraft can climb to while still meeting specified performance requirements. The game’s reference figure is not its current height or a guarantee for every situation.

How to read aircraft specifications
Contact

Something detected or being followed on the display. You may still need to establish what it is.

Related guide: plot or track
Knots

A unit of speed used in aviation: nautical miles per hour.

Related guide: trackblock
Cruise speed

A speed used for the main travelling part of a flight. A reference cruise speed is different from a track’s current speed.

Related guide: interceptor speed
Stall speed

A reference speed for the onset of a stall under specified conditions. A stall occurs when a wing or rotor blade exceeds its critical angle to the airflow and loses lift. It does not mean the engine has stopped.

How to read aircraft specifications
Range

Distance. For a contact it means distance from a stated point; an aircraft’s range means how far it can fly under stated conditions.

Nautical mile / NM

A distance unit used in aviation and navigation. It is different from the ordinary mile used on UK road signs.

Powerplant

The engine or engines that power the aircraft.
