The Lasta 95 is a light military trainer aircraft produced by UTVA. It is a tandem two-seater low-wing trainer with a metal airframe. The aircraft is capable of basic training functions including aerobatics, instrument and tactical flying. The first prototype flew on 2 September 1985. Lasta in Serbian is the swallow.
Design and development
The Lasta was originally developed to be a replacement of the Utva 75, which had been the most commonly used trainer aircraft of the Yugoslav Air Force up until 1991. The first prototype Lasta 1 was completed by the spring of 1985. And, following completion of the initial testing phase, the first flight was achieved on September 2, 1985. In January 1989, was issued a modified version – Lasta 2, a lighter, with shorter fuselage and a new electronics system including fire control Ferranti ISIS D-282. By early 1990s Utva, and her partner, have produced enough parts for the completion of 10 pre-production airframes. During the 1999 NATO bombing of Yugoslavia, all 5 existing prototypes were destroyed during the bombing of UTVA (a sixth prototype survived with damage and was donated to the Aviation Museum at Belgrade Nikola Tesla Airport).
In 2006 development of the Lasta was restarted. The new version was known as the Lasta 95. In 2009 it was announced that Iraq will purchase 20 of these trainer aircraft.
With its specifications and updated avionics, the aircraft will ensure full pilot training for all elements of airplane application including:
- basic flying,
- figure flying,
- navigation flying,
- basic elements of night flying,
- category II instrumental flight,
- basic elements of gunning, rocketing and bombing (GRB)
- Light close air support of counterinsurgency operations and area patrol / light attack missions
Future improvements and developments
It is possible to install ejection seats but with higher cost of the plane. It is also possible that new containers with armaments and sensors would be developed for Lasta 95.
There is a 3 factory version of Lasta 95.
This light piston-propeller training aircraft is primarily intended for initial and basic training of military pilots. With in-line tandem seating, the trainer was developed in accordance with the FAR (JAR) 23 regulations for acrobatic category of airplanes and it provides an easy transition to Kobac and then to jet at higher training levels. The LASTA is equipped with a six-cylinder 224 kW (300 HP) engine of the opposed-cylinder type, and a double metal propeller Hartzell HC-C2YR-4CF/FC 8475-6, which provide maximum flight velocity (at an altitude of 3000m and a take off weight of 1085 kg) of 345 km/h. The empty weight is 888 kg, and the maximum take off weight is 1210 kg. The total aircraft length is 7.97m. The trapezoidal wings have a wingspan of 9.7 m and a surface of 12.9 m². The altitude barrier of flight is 6000 m. This propeller-driven low-wing aircraft has a tricycle retractable landing gear. Onboard GPS and Instrument Landing System (ILS) support the operations during CAT-II weather conditions. The aircraft is equipped with Mode S transponder for flight identification.Besides for training purposes, it can be used for combat fire training, rocket firing and bombing. The armed version of the LASTA 95 can be equipped with 7.62 mm or 12.7 mm machine guns, 57 mm rocket launchers or bombs weighing up to 100 kg.
Lasta 95V-54 designation is for Serbian Air Force and Air Defence. Differences between Lasta 95N and Lats 95V-54 are in following:
- Engine Lycoming AEIO-580-B1A, with 315 hp (332 kW, under H = 0 and 2700 rpm)
- Double metal propeller HARTZELL HC-C2YR-4CF/FC 8475-8
- New propeller cap
- Modified primary flight commands
- Modified engine commands with less frictions
- New command for propeller steeping and engine mix in both cabins
- New instruments for measuring temperatures and oil pressure and temperatures of cylinder block and exhaust gases in both cabins
- New radio stations Bendix/King for UHF with antennas
- New gun sight AKN-09 Teleoptik Zemun who supports containers with Machine gun, bombs and unguided rocket launcher
- Two under-wing carrier for weapons max allowed 120 kg
- New glass cockpit with Garmin G500 avionics suites, which include primary flight display (PFD) and a multi-function display (MFD). The aircraft also integrates an instrumental flying simulation system.
- Introduction of new composites materials in some parts of plane
It is a same version like Lasta 95V-54 designated for export customers with possibility of slight differences at customer request.
- Iraqi Air Force - 20 delivered Lasta 95N (another 16 optional).
- Serbian Air Force - 2 prototypes and 15 serial aircraft Lasta 95V-54 ordered, 10 delivered.
