EMB-314 Super Tucano / ALX Trainer / Light Attack Aircraft, Brazil

The EMB-314 Super Tucano is an enhanced version, with faster speed and higher altitude, of the EMB-312 Tucano trainer aircraft which is operational in the Air Forces of 17 countries. The prototype of the Super Tucano first flew in 1992. Both Tucano and Super Tucano have been developed and built by Embraer of Brazil.

In 1995, Embraer was awarded a contract to develop a variant of the Super Tucano, known as the ALX or light attack aircraft, for the Brazilian Air Force (FAB), optimised for the environmental conditions of the Brazilian Amazon. The ALX is capable of operating day and night missions from remote bases and unpaved runways with minimal ground support. The first production aircraft was completed in 1999.

In August 2001, the Brazilian Air Force awarded Embraer a contract for 76 Super Tucano / ALX aircraft with options for a further 23. 51 of these aircraft are two seater versions, designated AT-29, which are stationed at the Natal Air Force Base and replace the AT-26 Xavante advanced jet trainers which are approaching the end of their operational lives. The remaining 25 aircraft are the single seat A-29 ALX version.

One of the main missions of the aircraft is border patrol under the Sistema de Vigilancia da Amazonia (SIVAM) programme. The first aircraft was delivered in December 2003. By September 2007, 50 aircraft had entered service. Final delivery of the aircraft is scheduled for 2008.

The main missions of the aircraft, in addition to basic and advanced pilot training, are border patrol and counter-insurgency operations.

The flight envelope of the aircraft is +7G and -3.5G. The aircraft's small size, small visual and radar signatures, together with high speed and agility give the aircraft high survivability. Additional survivability features include armour protection and critical systems redundancy.

In August 2001, the Dominican Republic signed a contract for the supply of ten Super Tucano aircraft, to be used for pilot training, internal security, border patrol and counter-narcotics trafficking missions.

In February 2005, Venezuela selected the EMB-314 Super Tucano. 12 aircraft were to be ordered, with a further 12 planned. The sale fell through because it was thought the USA would block the transfer of US-built components.

In December 2005, the Columbian Air Force placed a contract for 25 Super Tucano aircraft. The aircraft will be used for border patrol and internal security. The first five were delivered in December 2006. Elbit Systems has been contracted to supply the avionics suite.

In April 2008, the Chilean Air Force selected the EMB-314 Super Tucano, with a requirement for 12 aircraft.

Cockpit

The all-glass cockpit is fully night vision goggle compatible. Brazilian AF ALX aircraft are equipped with avionics systems from Elbit Systems Ltd of Haifa, Israel, including a Head-Up Display (HUD), advanced mission computer, navigation system and two 6in x 8in colour liquid crystal multi-function displays.

The head-up display with 24° field of view and the advanced weapon delivery system are integrated through a MIL-STD-1553B data bus. The pilot is provided with a Hands On Throttle And Stick (HOTAS) control.

The pilot is protected with Kevlar armour and provided with a zero/zero ejection seat. The clamshell canopy, hinged at the front and rear and electrically activated, is fitted with a de-icing system and features a windshield capable of withstanding, at 300kt, the impact of a 4lb bird. A Northrop Grumman On-Board Oxygen Generation System (OBOGS) is installed.

Weapons

The aircraft is fitted with two central mission computers. The integrated weapon system includes software for weapon aiming, weapon management, mission planning and mission rehearsal. On-board recording is used for post mission analysis.

The aircraft has five hardpoints for carrying weapons, and is capable of carrying a maximum external load of 1,500kg. The aircraft is armed with two wing-mounted 12.7mm machine guns with a rate of fire of 1,100 rounds a minute and is capable of carrying general-purpose bombs and guided air-to-air and air-to-ground missiles. Brazilian AF aircraft will be armed with the MAA-1 Piranha short-range infrared guided air-to-air missile from Orbita.

The two seat AT-29 is fitted with a forward-looking infrared AN/AAQ-22 SAFIRE turret on the underside of the fuselage. The SAFIRE thermal imaging system supplied by FLIR Systems is for targeting, navigation and target tracking. The system allows the aircraft to carry out night surveillance and attack missions.

Navigation

The aircraft is equipped with an advanced laser inertial navigation and attack system, a Global Positioning System (GPS) and a Traffic alerting and Collision Avoidance System (TCAS).

Engine

The EMB-314 Super Tucano is powered by a PT6A-68A turboprop engine, developing 969kW. The power plant is fitted with automatic engine monitoring and control. The ALX aircraft has a more powerful engine than the EMB-314. The ALX's Pratt and Whitney Canada PT6A-68/3 turboprop engine, rated at 1,600shp, drives a Hartzell five-bladed constant speed fully feathering reversible pitch propeller.

The fuel capacity is 695l, which gives a range of over 1,500km and endurance of 6hrs 30mins. The aircraft has a cruising speed up to 530km/h with a maximum speed of 560km/h.
