From its founding as a company in 1927, Cessna firmly established itself in the single piston engine, general aviation category. Even though the company had produced the T-50 Bobcat from 1934 to 1944, it wasn’t until 1954 when Cessna started producing its first modern twin engine aircraft, the Cessna 310. This was followed in the 1960s by the likes of, among a range of other models, the Cessna 336/337, Cessna 340, and Cessna 401. It was during this time, that Cessna also started the development of the first of their business jet range, the Cessna Citation I. Something was still missing in the Cessna aircraft range though, a turboprop aircraft. It would still take until the mid-1970s when Cessna developed an aircraft to fill the gap between their piston engine and jet aircraft, and so, the Cessna 441 Conquest II was born.

Alabeo continue to focus on producing aircraft which, whilst not necessarily the most famous or most produced, are iconic aircraft in their own right for the history or development significance they represent, a position which the Cessna 441 Conquest II fits more than adequately. So, if you are a flight simming general aviation devotee, a fan of Cessna aircraft, or twin engine aircraft in general, then the Alabeo Cessna 441 Conquest II is something to seriously look at.


The Cessna 441 Conquest II is a twin engine, pressurised, low wing monoplane in the general aviation aircraft category. It is powered by a pair of Garrett TPE331-8 turboprop, 636 shp engines and has seating for up to 10 passengers. Developed from the Cessna 404 Titan, the Cessna 441 Conquest II was designed to fill the gap between Cessna’s piston engine and jet aircraft. Its first flight was in 1975 and the aircraft entered production in 1977. Operated by corporate owners, air charter operators, and most notably, the Royal Flying Doctor Service in Australia, the Cessna 441 Conquest II ceased production in 1987 after a production run of 362 aircraft.

Visual Appearance

General Exterior and Interior. The design of the Cessna 441 Conquest II typifies general aviation twin engine aircraft of the era and it follows the design lines of its pedigree, the Cessna 404 Titan. Alabeo have modelled the Cessna 441 Conquest II on an early production variant and they have done this aircraft justice in capturing the distinctive appearance with the elongated nose and very distinctive, compact profile, Garrett turboprop engines. The interior is modelled on an executive configuration with a cabin layout of four seats in a club seating arrangement, two individual seats, and a generous luggage storage space at the rear. Textured wood panels, seating, carpet, and padded side panels are typical of the model and consistent with the quality seen in the Alabeo model range. The cabin is luxuriously appointed, but is still presented with a degree of wear and tear to give a realistic and true appearance and feel of an aircraft of this type. The lambswool seat covers on the pilot and co-pilot seats are a nice touch of comfort and should make those long trips more comfortable.

Flight Instruments and Systems. The cockpit of the Cessna 441 Conquest II represents the typical layout for the aircraft and the production period. The standard analogue flight instruments are typical of the model range and consistent with an aircraft of this category and age, and they are supplemented with the Garmin GNS 530 GPS unit. Whilst the Stormscope is present, it is only functional in FSX.

Models and Liveries. The Cessna 441 Conquest II is provided in a single model with five individual liveries (a selection only shown below). Each aircraft has a unique aircraft registration number and there is an additional blank texture for aircraft painting enthusiasts. Displaying the usual Alabeo high quality, the surface textures, reflections, and shadings, along with additional scuff marks, scrape effects, dirt, oil, and grease stains, give each aircraft a realistic appearance.

Summary, Issues, and Variations. Alabeo have followed in the footsteps of their sister company, Carenado, representing their products with an extremely degree of quality and realism and the rendition of the Cessna 441 Conquest II is consistent with this. The aircraft is highly detailed and accurate, the visual quality is excellent, and it provides a faithful representation of the real-world aircraft. The photo like qualities of the interior make for an easy and pleasurable environment in which to fly and all elements of the cockpit are clear and easy to read, with the typical range of various alternative cockpit camera views to provide more detailed clarity. Any noted visual variations were minor and are considered to be related to real world production variations or a degree of artistic licence on the part of the developer. Any noted issues and variations with cockpit functions and operation were considered minor and / or in the interests of simplifying the function for practical flight simulator use.

Animations, Lighting and Sounds

The animations of the primary and secondary control surfaces and other moving elements on the Cessna 441 Conquest II are all modelled faithfully and include:

primary control surfaces – ailerons, elevator, and rudder;
secondary control surfaces – flaps;
others – elevator and rudder trim tabs, cabin door, baggage compartment door, avionics bay door, and cockpit windows; and
various static elements.

The lighting and lighting effects on the 441 Conquest II are excellent and are a realistic representation of the real world aircraft. The engine sounds are a very good representation, delivering the typical high pitched sound of a turboprop, and with good stereo separation with view movement in the Virtual Cockpit view and external views.

General Characteristics and Performance Specifications

The general characteristics and performance specifications for the Cessna 441 Conquest II are provided in the table. This is based on data from the official Cessna 441 Conquest II Pilot Operating Handbook, data provided by Alabeo, and general research sources. Some of this data varies between sources and also may be an approximation due to variances in data and the specific aircraft modelled by Alabeo.

Flight Performance

A specific Test Flight was conducted to test the flight performance of Alabeo’s Cessna 441 Conquest II. The flight was conducted in clear weather with a full fuel load and the aircraft at maximum take-off weight (MTOW). A cruise altitude of 25,000 ft was adopted and the route distance was particularly chosen to provide a basis upon which to test the range characteristics of the 441 Conquest II.

The aircraft was easy to taxi. With flaps set to the take-off position, aircraft rotation occurred at approximately 100 KIAS and effortlessly lifted off the runway, with a climb out which was expected for the aircraft. The 441 Conquest II is not only very agile, it is a virtual rocket and it quickly establishes on the climb to cruise with its rate of climb of over 2,400 ft/min. This made the climb effortless and quickly established the aircraft at the cruise altitude.

During cruise, a power setting was established for cruise as per the performance tables. This cruise setting produced an average speed, fuel flow rate and an endurance reasonably consistent with the performance tables and the characteristics of the aircraft. Any noted variances in performance were minor and had negligible impact on the operation of the aircraft. The Test Flight confirms the modelling of the aircraft for speed and range performance to be reasonably accurate.

Configured for landing, with full flaps, and trimmed for a descent rate of approximately 500 ft/min, the aircraft’s approach speed was approximately 100 KIAS and it touched down at approximately 90 KIAS, with a landing roll out comparable with the specifications for the aircraft.

In testing the accuracy of the instruments, based on the measured Test Flight, the speed indications on the airspeed indicator, were consistent with the averages measured. Additionally, when establishing a set rate of climb on the vertical speed indicator, the respective gain in altitude on the altimeter was achieved within the measured minute, and a standard rate turn was achieved within the measured two minute period using the turn coordinator.

The performance of Alabeo’s Cessna 441 Conquest II was excellent in flight, displaying the expected general flight characteristics of this aircraft. The aircraft’s handling characteristics are very good, and it exhibits the typical high performance of a turboprop. It is agile and responsive to control inputs and also very steady once trimmed for level flight or established on approach. Overall, the aircraft model displays a reasonably accurate rendition of the flight characteristics and performance expected of this type of aircraft.
