Short Tucano
From Wikipedia, the free encyclopedia
The Short Tucano T Mk 1 is a two seat turboprop basic trainer used by the RAF. It is an adaptation of the EMBRAER Tucano by Short Brothers, the principal alteration being the use of a more powerful Garrett turboprop powerplant over the standard Pratt & Whitney engine.

[edit] Development
The Shorts Tucano was developed from the EMBRAER Tucano by Short Brothers in order to meet a requirement to replace the Jet Provost as the basic trainer for the RAF, as laid down in Air Staff Target 412. It was fitted with a more powerful Garrett engine in place of the Tucano's original Pratt & Whitney Canada PT6 engine, to give higher performance, particularly at low level.
Aside from a different powerplant, the other differences between the Short Tucano and the EMBRAER Tucano are:
- A strengthened airframe.
- A new cockpit layout similar to the Hawk advanced trainer.
- A four, as opposed to three, bladed propeller.
- Ventral airbrake and restyled wingtips.
- The fitting of Martin-Baker MB 8LC ejection seats for both crew.
The Tucano was selected in 1985 in preference to the Pilatus PC-9, the British Hunting Firecracker and the Australian Aircraft Consortium Wamira. The first Garrett engined Tucano flew in Brazil on 14 February [1986]], with the first Shorts built production aircraft flying on 30 December 1986 [1] . The decision to replace the engine used in the standard EMBRAER model with the Garrett engine caused a number of problems which delayed the introduction of the aircraft, so that it was 1989 by the time it came into service.
[edit] Operational history
In service the Tucano has proven to be 70% cheaper to operate than its predecessor. It has a greater range and endurance than the Jet Provost which allows it to fly two consecutive sorties before being refuelled.
