The CAMS 46 was a flying boat trainer aircraft built in France in the mid-1920s, essentially an updated version of the CAMS 30 that had flown in 1922. While retaining that aircraft's basic form, CAMS offered the French Navy two new versions with aerodynamic refinements over the earlier aircraft: the CAMS 46 E primary trainer, and the CAMS 46 ET intermediate trainer. Only the latter was selected for production and was built in quantity to supply one escadrille at the Naval training station at Hourtin.

Flying boat aircraft equipped with a boat hull for operation from water

A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water, that usually has no type of landing gear to allow operation on land. It differs from a floatplane as it uses a purpose-designed fuselage which can float, granting the aircraft buoyancy. Flying boats may be stabilized by under-wing floats or by wing-like projections from the fuselage. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during World War II. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used for maritime patrol and air-sea rescue.

Trainer aircraft Aircraft designed for training of pilots and aircrew

A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their real-time piloting, navigation and warfighting skills without the danger of overextending their abilities alone in a fully featured aircraft.

France Republic with mainland in Europe and numerous oversea territories

France, officially the French Republic, is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories. The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. It is bordered by Belgium, Luxembourg and Germany to the northeast, Switzerland and Italy to the east, and Andorra and Spain to the south. The overseas territories include French Guiana in South America and several islands in the Atlantic, Pacific and Indian oceans. The country's 18 integral regions span a combined area of 643,801 square kilometres (248,573 sq mi) and a total population of 67.3 million. France, a sovereign state, is a unitary semi-presidential republic with its capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban areas include Lyon, Marseille, Toulouse, Bordeaux, Lille and Nice.

Power-to-weight ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance.

Bernard 190 Aircraft

The Bernard 190 or Bernard-Hubert 190 was a French airliner of 1928. It was a high-wing cantilever monoplane of conventional configuration, based on the Bernard 18. Compared with its predecessor, it kept the same basic design but featured redesigned tail surfaces, an enlarged cabin, and offered its flight crew a completely enclosed cockpit. Also like its predecessor, the basic airliner model provided the basis for a long-range aircraft to be used in record attempts, the 191GR.

Blériot 115

The Blériot Bl-115 was a French biplane airliner of the 1920s, best remembered for the part it played in the French exploration of Africa. For its day, it was a large aircraft, mounting one pair of engines on the upper wing and one pair on the lower. First flying on 9 May 1923, the prototype crashed on 23 June, killing its pilot, Jean Casale.

Blériot 127

The Blériot 127 was a French bomber aircraft of the 1920s and 1930s, developed from the Blériot 117 escort fighter. It was a large monoplane of conventional configuration that featured open gunner's positions in its nose and at the rear of its two underwing engine nacelles. The wing airfoil was of sufficient thickness that these latter positions could be accessed from the fuselage in flight.

The Blériot-SPAD S.81 was a French fighter aircraft developed in 1923 to a requirement by the French Air Force. It was flown competitively against the Dewoitine D.1 and was selected over that aircraft due to the Dewoitine's more radical design, leading to an order for 80 aircraft. The S.81 was a single-bay biplane of conventional configuration with I-shaped interplane struts and lacking Herbemont's usual swept upper wing. It featured a wooden fuselage of monocoque construction and metal wings skinned in fabric. Production versions differed from the prototypes in having a lengthened fuselage and larger tail fin.

Breda A.4

The Breda A.4 was a biplane trainer produced in Italy in the mid-1920s. It was of conventional configuration with a two-bay unstaggered wing cellule and seating for the pilot and instructor in tandem open cockpits. Apart from civil use, the A.4 was also adopted by the Regia Aeronautica as a trainer. At least some examples were produced in floatplane configuration as the A.4idro.

CAMS 30E

The CAMS 30E was a two-seat flying boat trainer built in France in the early 1920s. It was the first aircraft designed for CAMS by Raffaele Conflenti after he had been recruited by the company from his previous job at Società Idrovolanti Alta Italia (SIAI). It was a conventional design for the era featuring a two-bay equal-span unstaggered biplane wing cellule. The prototype was exhibited at the 1922 Salon de l'Aéronautique and evaluated the following year by the Aéronautique Maritime. The type's favourable performance led to an order of 22 machines for the French military and an export order of seven for Yugoslavia and four for Poland.

CAMS 55 reconnaissance flying boat

The CAMS 55 was a reconnaissance flying boat built in France in the late 1920s which equipped the French Navy throughout the 1930s.

Farman F.120 airliner family built by Farman Aviation Works

The Farman F.120 and its derivatives were a family of multi-engine airliners and bombers of the 1920s built by the Farman Aviation Works in France.

Dewoitine D.19

The Dewoitine D.19 was a fighter aircraft built in France in 1925 in response to a French Air Force solicitation.

FBA 21

The FBA 21 and 23 were small flying boat airliners built in France in the mid-1920s. Their development was an attempt by FBA to develop a commercial version of their FBA 19 bomber which had failed to attract orders from military buyers. Retaining the same basic design as their predecessor, the Model 21 added an enclosed cabin for four passengers. Unfortunately for FBA, they aroused as little interest as their military counterparts, and only a handful were built in a number of slight variations, including one example of a dedicated mail plane.

The Renard Epervier was a Belgian prototype single-seat all-metal fighter monoplane designed by Alfred Renard at the Societé Anonyme Avions et Moteurs Renard for a government-sponsored design contest in 1928. The Epervier Type 2 was built and flown in 1928, by Belgian aircraft manufacturer Stampe et Vertongen. It carried an armament of two synchronised 7.7mm guns and was lost in September 1928 after failing to recover from a flat spin. A second prototype, the Epervier Type 2bis, introduced revised streamlined fairings for the cantilever mainwheel legs, mainwheel spats and cylinder aft-fairings and was built by SABCA.

The Lioré et Olivier LéO H-13 was a French biplane two-engine flying boat of the 1920s, built in passenger and military variants.

Letord Let.5

The Letord Let.5 was probably the most numerous of a family of 3-seat reconnaissance bombers, designed and built in France from 1916, originally to an A3 specification from the STAé.

Levasseur PL.5

The Levasseur PL.5 was a carrier-based fighter produced in France in the late 1920s, in response to the 1924 AMBC.2 specification issued by the Service Technique de l'Aéronautique (STAé). It was a conventional, single-bay sesquiplane that carried a crew of two in tandem, open cockpits. Like other Levasseur naval designs of the day, it incorporated several safety features in case of ditching at sea. Apart from small floats attached directly to the undersides of the lower wing, the main units of the fixed, tail-skid undercarriage could be jettisoned in flight, and the underside of the fuselage was given a boat-like shape and made watertight.

Lioré et Olivier LeO H-190

The Lioré et Olivier H-190 was a flying boat airliner produced in France in the late 1920s. Conventional for its day, it was a single-bay biplane with un-staggered wings, its single engine mounted tractor-fashion underneath the upper wing and supported on struts in the interplane gap. Early examples had the pilot's open cockpit located aft of the wing, but this was later relocated forward of the wing.

The Nieuport-Delage NiD 38 was a touring aircraft built in small numbers in France in the early 1920s. It was a single-bay biplane of conventional design with an enclosed cabin for two passengers and an open cockpit for the pilot.

Potez X

The Potez X was a French 1920s general-purpose colonial transport aircraft designed and built by Potez.

The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s. It was a conventional, single-bay biplane with staggered wings of unequal span that were braced with N-struts near their tips. The fixed undercarriage consisted of two mainwheels that were joined by a common through axle, plus a tailskid. The student pilot and the instructor sat in open cockpits in tandem that were fitted with dual controls. Construction was of mixed materials, with metal used for the undercarriage, engine mount, and cabane struts. The control surfaces were operated by a rigid linkage made of dural tube. The horizontal stabilizer was adjustable in flight, using a lever in the cockpit to adjust the aircraft's trim. Incorrect use of this latter feature led to a number of accidents. The base model RSV 22/180 was powered by a 134-kW (180-hp) Hispano-Suiza engine, but the aircraft was designed to use powerplants of up to 220 kW (300 hp). The RSV 22/200 variant used a 150-kW (200-hp) Renard-built radial engine in place of the Hispano-Suiza.

CAMS 36

The CAMS 36 was a 1920s French flying boat designed and built by Chantiers Aéro-Maritimes de la Seine. It was originally conceived as a single-seat fighter but evolved as a racer to compete in the 1922 Schneider Trophy race. Lack of funds in 1922 and an accident in 1923 meant the two aircraft built failed to participate in a Schneider race.

Blériot-SPAD S.42 1920s French training aircraft

The SPAD S.42 was a French biplane trainer aircraft of the early 1920s, developed by Société Pour L'Aviation et ses Dérivés (SPAD) from prolific SPAD S.XIII fighter.
