The AW119 is a single-engine multirole helicopter. AgustaWestland promote the type as possessing excellent flight qualities with high levels of controllability, maneuverability and inherent safety. The design of the rotorcraft is derived from Agusta's earlier and highly successful
A109 helicopter, differing primarily by being equipped with a single engine (as the A109 was originally designed), The AW119 shares the same cockpit and cabin of the AW109, along with commonality with various other systems, while costing roughly half of the latter's price tag. The AW119 employs a four-bladed fully articulated main rotor; the composite
rotor blades are designed to produce maximum lift with minimum noise, and feature tip caps to reduce noise and elastomeric bearings with no lubrication requirements. Aluminium
honeycomb structural panels are used throughout the airframe, which absorb both noise and vibration, thus requiring no additional vibration absorption systems to be employed. The PT6B-37A powerplant of the AW119, located in the same area as the AW109's engines, is capable of providing high power margins along with generous speeds and endurance. According to AgustaWestland, the AW119 retains the system redundancy of dual engine helicopters, such as the
hydraulics and the dual independent stability augmentation systems. The
gearbox has a 30-minute dry run capability. Initial production models featured conventional flight instruments; the
Garmin G1000 glass cockpit is integrated on the newer AW119Kx variant, which is claimed to improve situational awareness, reduce pilot workload, and increase safety. Primary flight and other key information is displayed to the pilots upon two large 10.4 inch multi-function displays in the cockpit; an independently powered stand-by display is also present in case of system failure. Other avionics used include a 3-axis
aircraft flight control system (AFCS), Synthetic Vision System (SVS), Highway In The Sky (HITS) depiction,
moving map display,
radio altimeter,
VOR/
ILS/
GPS/
WAAS navigation, Aural Warning Generator, and embedded
Helicopter Terrain Avoidance Warning System (HTAWS). A variety of equipment can be equipped, dependent on operator choice and role; these include an external hoist, dual
cargo hook, dual
flight controls, baggage compartment extension, snow skis, windshield wipers, rotor brake, multi-band
radios, active noise reduction headsets,
soundproofing, oxygen systems,
loud speakers, search lights, retractable landing light, emergency floatation equipment, reinforced windshield,
wire strike protection system,
rappelling kit, fire fighting belly tank, and a
forward looking infrared (FLIR) camera. Three fuel tanks, located behind the rear seats in the cabin, are installed as standard; up to two additional optional tanks can be fitted for a total of five, providing a flight endurance of nearly six hours. ==Operational history==
