and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers. The Tiger Moth remained in service with the RAF until it was replaced by the de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is still occasionally used as a primary training aircraft, particularly for those pilots wanting to gain experience before moving on to other tailwheel aircraft. Many Tiger Moths are now employed by companies offering trial lesson experiences. The de Havilland Moth club, founded in 1975, is now an owners' association offering a mutual club and technical support.

Improvements made on the Tiger Moth monoplane were incorporated into a military trainer variant of the DH.60 Moth, the DH.60T Moth – the ''T'' coming to stand for 'Tiger' in addition to 'Trainer'. The DH.60T Moth had several shortcomings, thus was subject to several alterations, such as the adoption of shortened interplane struts to raise the wingtips after insufficient ground clearance was discovered while it was undergoing trials at RAF Martlesham Heath. As a result of the Martlesham trials, a favourable report for the type was produced, which in turn led to the type soon being formally adopted as the new basic trainer of the

One of the main changes from the preceding Moth series was improved access to the front cockpit, since the training requirement specified that the front-seat occupant had to be able to escape easily, especially when wearing a parachute.Bain 1992, p. 43. Access to the front cockpit of the Moth's predecessors was restricted by the proximity of the aircraft's fuel tank, directly above the front cockpit, and the rear cabane struts for the upper wing. The solution adopted was to shift the upper wing forward but sweep the wings back to maintain the same centre of lift. Other changes included a strengthened structure, fold-down doors on both sides of the cockpit, and a revised exhaust system.

Design

de Havilland Gipsy The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (3 ...
III 120 hp engine; later models are often fitted with more powerful models of this engine, while some have been re-engined by third-party companies. One characteristic of the Tiger Moth design is its differential aileron control setup. The ailerons (on the lower wing only) on a Tiger Moth are operated by an externally mounted circular bell crank, which lies flush with the lower wing's fabric undersurface covering. This circular bell crank is rotated by metal cables and chains from the cockpit's control columns, and has the externally mounted aileron pushrod attached at a point 45° outboard and forward of the bell crank's centre when the ailerons are both at their neutral position. This results in an aileron control system operating with barely any travel down at all on the wing on the outside of the turn, while the aileron on the inside travels a large amount upwards to counteract
adverse yaw Adverse yaw is the natural and undesirable tendency for an aircraft to yaw in the opposite direction of a roll. It is caused by the difference in lift and drag of each wing. The effect can be greatly minimized with ailerons deliberately designed to ...
. From the outset, the Tiger Moth proved to be an ideal trainer, simple and cheap to own and maintain, although control movements required a positive and sure hand as a slowness to control inputs existed. Some instructors preferred these flight characteristics because of the effect of "weeding out" the inept student pilot.


Production

The Tiger Moth quickly became a commercial success, and examples were sold to more than 25 air forces. In addition to the military demand, aircraft were also produced for the civilian market. At one point, the flow of orders for the Tiger Moth effectively occupied almost the entirety of de Havilland's capacity to manufacture aircraft, and little capacity could be spared to accommodate domestic customers.Jackson 1966, pp. 4–5. In 1932, de Havilland also developed an affordable air taxi from the Tiger Moth, using many of the main components of the former with a new plywood fuselage seating four people in an enclosed cabin; it was marketed as the

Operational history


Introduction

The RAF ordered 35 dual-control Tiger Moth Is, which had the company designation DH.82. A subsequent order was placed for 50 aircraft powered by the de Havilland Gipsy Major I engine (130 hp) which was the DH.82A or to the RAF Tiger Moth II. The Tiger Moth entered service at the

in February 1932. During the prewar years, increasing numbers of Tiger Moths were procured for the RAF and by overseas customers; by 1939, nearly 40 flying schools operating the type had been established, nine of which operated civilian-register models, as well.Jackson 1966, pp. 5–6. From 1937 onwards, the Tiger Moth was made available to general flying clubs, production having been previously occupied by military customers. The type was used to replace older aircraft in the civilian trainer capacity, such as the older

and Gipsy Moth. By the start of the Second World War, the RAF had around 500 Tiger Moths in service. In addition, nearly all civilian-operated Tiger Moths throughout the Commonwealth were quickly impressed into their respective air forces to meet the wartime demand for trainer aircraft.


Training

The Tiger Moth became the primary trainer throughout the Commonwealth and elsewhere. It was the principal type used in the British Commonwealth Air Training Plan, where thousands of military pilots got their first taste of flight in a Tiger Moth. The RAF found the Tiger Moth's handling ideal for training fighter pilots. Generally docile and forgiving in the normal flight phases encountered during initial training, when used for aerobatic and formation training, the Tiger Moth required skill and concentration to perform well; a botched manoeuvre could cause the aircraft to stall or spin. From 1941 onwards, all military and many civilian Tiger Moths were outfitted with antispin

of the tailplane, known as Mod 11'; later on, the aileron mass balances were removed for improved spin recovery performance.


Gunnery target drone

In 1935, the DH.82 Queen Bee, a pilotless, radio-controlled variant of the Tiger Moth, appeared for use in training antiaircraft gunners. Use of the word

, as a generic term for pilotless aircraft, apparently originated from the name and role of the Queen Bee (i.e. the word drone is a reference to the male bee, which makes one flight in search of the female queen bee and then subsequently dies). The DH.82 had a wooden fuselage, based on that of the DH.60 Gipsy Moth (with appropriate structural changes related to cabane strut placement) and the wings of the Tiger Moth II. Queen Bees retained a normal front cockpit for test-flying or ferry flights, but had a radio-control system in the rear cockpit to operate the controls using pneumatically driven

to dive; one aircraft would then remain in the vicinity while the other would search for a naval patrol vessel that could be led back to the spot. Because they were not radio equipped, each aircraft also carried a pair of homing pigeons in a wicker basket to call for help in case of a forced landing at sea. A 25-lb (11.5 kg) bomb was sometimes carried, but no record shows one being dropped in action.


Anti-invasion preparations

In the aftermath of Britain's disastrous campaign in France, in August 1940 three proposals for beach defence systems were put forward; 350 Tiger Moths were fitted with bomb racks to serve as light bombers as a part of Operation Banquet. A more radical conversion involved the "paraslasher", a scythe-like blade fitted to a Tiger Moth and intended to cut parachutists' canopies as they descended. Flight tests proved the idea, but it was not officially adopted. The Tiger Moth was also tested as a dispenser of Paris green rat poison for use against ground troops, with powder dispensers located under the wings.


Postwar

In the postwar climate, impressed Tiger Moths were restored to their former civilian operations and owners.Jackson 1966, p. 12. Accordingly, large numbers of Tiger Moths were made available for sale to flying clubs and individuals. Relatively few new light aircraft being manufactured at the time to take its place.Jackson 1966, pp. 12–13. Due to the type being inexpensive to operate and the aforementioned factors, the Tiger Moth was met with an enthusiastic reception across the civilian market. Additionally, it was put to use for new roles,including aerial advertising, aerial ambulance, aerobatic performer, crop dusting, and glider tug work. In the air-racing market, Tiger Moths were converted to a single-seat configuration, often temporarily. Several aircraft were extensively modified for greater speed; these changes included alterations such as the removal of the centre-section fuel tank,

These aircraft were required by the Dutch civil aviation authorities to be fitted with a larger dorsal fin, incorporating an extended forward fillet to the fin, to provide for additional area; this requirement was also extended to privately owned Tiger Moths in the Netherlands. The Tiger Moth might be confused at first glance with the Belgian-designed Stampe SV.4 aerobatic aircraft, which had a very similar design layout; both aircraft made use of a similar main landing gear configuration, a slightly sweepback wing, and an alike engine/cowling design.

Flying characteristics

The Tiger Moth responds well to control inputs and is fairly easy to fly for a tail-dragger. Its big "parachute" wings are very forgiving, and it stalls at a speed as slow as 25 knots with power. Its stall and spin characteristics are benign. It has some adverse yaw and therefore requires rudder input during turns."Pilot's Notes for Tiger Moth Aircraft." ''R.A.A.F. Publication No. 416'', February 1941. The Tiger Moth exhibits the fundamental requirements of a training aircraft, in being "easy to fly, but difficult to fly well"; the aircraft's benign handling when within its limits make it easy for the novice to learn the basic skills of flight. At the same time techniques such as coordinated flight must be learnt and used effectively, and the aircraft will show up mishandling to an observant instructor or attentive pupil. As training progresses towards more advanced areas, especially aerobatics, the skill required on the part of a Tiger Moth pilot increases. The aircraft will not, like some training aircraft, "fly its way out of trouble" but will instead stall or spin if mishandled. However the stall and spin remain benign, again showing up deficient piloting without endangering the aircraft or the crew. These characteristics were invaluable to military operators, who must identify between pilots with the potential to go on to fly fighter aircraft, those more suited to lower-performance machines and those who must be relegated to non-pilot aircrew positions. Because the Tiger Moth has no electrical system, it must be started by hand. This needs to be done with care to prevent being struck by the propeller, which would result in serious injury. Being a tail-dragging biplane, taxiing also requires care. The pilot cannot see directly ahead, so the lower wing can hit obstructions, and it is susceptible to gusts of wind on its inclined, large, upper wing. The takeoff is uneventful, and it has a reasonable rate of climb. However full power should not be maintained for more than a minute to avoid damaging the engine. The Tiger Moth's biplane design makes it strong, and it is fully aerobatic. However it has ailerons only on its bottom wing, which makes its rate of roll relatively slow for a biplane; and, as stated previously, the ailerons on a Tiger Moth normally operate with a heavy degree of designed-in differential operation (mostly deflecting up, hardly at all downwards) to avoid
adverse yaw Adverse yaw is the natural and undesirable tendency for an aircraft to yaw in the opposite direction of a roll. It is caused by the difference in lift and drag of each wing. The effect can be greatly minimized with ailerons deliberately designed to ...
problems in normal flight. Most manoeuvres are started at about 90 to 110 knots, and it has a Velocity Never Exceeded (VNE) of 140 knots. It is important to lock the automatic slats (leading edge flaps) during aerobatic manoeuvres. There are two methods of landing. "Wheeler" landing involves pushing the plane on to the runway at a moderate speed with just the main wheels on the ground, with the tail held up until speed reduces. It does not tend to bounce. Unlike most taildraggers, slow speed Conventional landing gear, three-point landings are quite difficult because there is not enough elevator authority to bring the tail down to the correct three-point attitude. This means that the tail needs to be brought down sharply at just the right speed in order for the angular momentum to carry it down sufficiently. The open cockpit allows pilots to move their heads over the side to see the runway during approach and landing. As the aircraft is a tail dragger, it is essential to land it straight with no sideways movement, to avoid ground loops. One often undocumented feature is that the carburettor de-icing mechanism is activated automatically when the throttle is reduced. This means that when an engine is running poorly due to ice the pilot must reduce power even further and then wait for the ice to melt.


Variants

;DH.60T Moth Trainer/Tiger Moth :Military training version of the De Havilland de Havilland Gipsy Moth, DH.60 Moth. First eight prototype DH.82 configuration aircraft were named Tiger Moth. ;DH.82 Tiger Moth (Tiger Moth I) :Two-seat primary trainer aircraft. Powered by a 120 hp (89 kW) De Havilland Gipsy, de Havilland Gipsy III piston engine; renamed ''Tiger Moth I'' in RAF. ;DH.82A Tiger Moth (Tiger Moth II) :Two-seat primary trainer aircraft.

de Havilland Gipsy Major The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintag ...
piston engine and fitted with a hood over the rear cockpit for blind flying instruction. Named ''Tiger Moth II'' in RAF. ;DH.82B Tiger Moth III :Improved variant with a de Havilland Gipsy Major, de Havilland Gipsy Major III engine, it had a wider fuselage and larger fin. First flown on 1 October 1939 only one was built. In some references the designation is erroneously applied to the Queen Bee. ;DH.82C Tiger Moth :Cold weather operations version for the RCAF. Fitted with sliding perspex canopies, cockpit heating, brakes, tail wheels and metal struts. Wheels were moved forwards by 9.75" to compensate for the installation of brakes by changing the angle of the undercarriage legs. Powered by a 145 hp (108 kW) de Havilland Gipsy Major piston engine. 1,523 built (including Menasco Moths and PT-24). ;DH.82C-2 Menasco Moth I :DH.82C fitted with Menasco D-4 Super Pirate 125 hp inline inverted 4-cylinder engine due to shortages of Gipsy Major engines. Because of the reduction in power, they were used primarily as radio trainers. Externally distinguishable from 82C by opposite rotation of propeller and reversal of the cowling openings. 10 built. ;DH.82C-4 Menasco Moth II :As DH.82C-2 but with reduced fuel capacity and further detail alterations. One example survives and is on display at Canada Aviation and Space Museum in Ottawa. 125 built. ;DH.82C-4 Menasco Moth III :Fitted with American AT-1/AR-2 radio and intended as a radio trainer from outset but project cancelled when shortages of British radios and engines was resolved. The sole example, RCAF 4934 was converted from Menasco Moth II. ;DH.82 :A target drone for anti-aircraft gunnery training. It could be flown unmanned under radio-control, but was also fitted with a cockpit so it could be flown by a pilot. Tiger Moth wings were used and, to reduce cost, a wooden fuselage based on that of the DH.60 Moth (but with the structural changes associated with the cabane struts having been relocated as per the standard Tiger Moth) was used. Between 1935 and 1943, 412 were built in float and wheeled versions. As of 2008, the sole remaining airworthy Queen Bee resided at RAF Henlow, England. ;PT-24 Moth :United States military designation for the DH.82C ordered for Lend-Lease to the
