Aircraft used for this purpose include the Slingsby Firefly, as at one time used by the United States Air Force Academy, and the Scottish Aviation Bulldogs of the RAF.
Those who are judged unsuitable for a pilot commission, but show other attributes, may be offered the chance to qualify as navigators and weapons officers.
The USAF Academy uses light piston-powered aircraft such as the Cirrus SR20 (designated T-53A) for basic cadet flight training.
Modern advanced trainers feature programmable multi-function displays which can be programmed to simulate different electronic systems and scenarios.
][9] The on-board avionics system may be linked to ground-based systems, and together they can simulate situations such as infrared or radar guided missile, interceptors, air-to-air and surface-to-air missiles, anti-aircraft batteries, radars, chaff and flare countermeasures and collision warnings, in low or dense electronic warfare environments.
For example, the Boeing 707 was a popular airliner for conversion to tanker, transport and ELINT variants by numerous air forces.
Some jet trainers, such as the Aermacchi MB-339, Casa C-101, Folland Gnat, Fouga Magister and British Aerospace Hawk, are used by national formation aerobatic teams.
Early jet aerobatic teams tended to use combat types such as the Hawker Hunter, English Electric Lightning, and North American F-100 Super Sabre.
As air forces' combat fleets were scaled-down, it made sense for most national display teams to change to lighter training types.
A few modifications may be needed to enable coloured smoke to be emitted during displays, but essentially these airframes can still perform their pilot training function.
However, most of these aircraft do not have the counter measures and sensors required to survive alone in a modern high intensity war fighting scenario, for example being vulnerable to MANPADS.
Especially against opponents operating without a fighter screen or an effective anti-aircraft capability, such trainer derived attack aircraft could perform adequately.
[12][13] Despite their vulnerability, even small numbers of weapons-carrying trainer aircraft may achieve a disproportionate effect due to the element of surprise, especially when the attacked side believes to hold air supremacy.
[16] In high-intensity conflicts, advanced trainer type aircraft can have a military utility if they operate under an umbrella of other aerial assets.
Although never tested it was believed that the Hawk, combined with AIM-9L and flown by some of the best pilots in the RAF including those from the Red Arrows, would have made a viable air defence fighter.
With increasing costs, even major air forces will have difficulty reaching the economies of scale to justify development of new advanced trainers.
Pilots who had mastered ground handling would then graduate to lower powered two seaters, before finishing on obsolete fighters.
The supply of obsolete aircraft proved inadequate and production of Caudron G.III, Nieuport 83 and other types specifically for training was undertaken.
Between the World Wars, purpose built trainers covering a variety of specialties largely replaced obsolete types in the Western armed forces, including aircraft specifically for bombing and gunnery and navigational training.
By World War II, however, their needs exceeded what could be spared from production and although using a number of purpose built designs such as the Bücker Bü 131, relied largely on captured aircraft and obsolete combat types.
