Source measurement	During March 2012, Indian Rotorcraft broke ground on a 40,000m 2 new facility adjacent to Rajiv Gandhi International Airport , Hyderabad , India; The first helicopters to be manufactured by the joint venture is slated to be the AgustaWestland AW119 Ke; other types, such as the AgustaWestland AW101 , are likely to follow in the future.^[source]AgustaWestland AW119 Koala · Development; only the objects and conditions stated in this passage 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.^[source]AgustaWestland AW119 Koala · Design; only the objects and conditions stated in this passage The AW119 Koala has been used for various roles, including utility, emergency medical services (EMS), offshore, law enforcement , and executive transport. A key selling point of the type is its wide-body fuselage, which allows for up to seven passengers to be seated in a three-abreast configuration in the cabin; for the EMS mission, up to two stretchers along with medical attendants and full emergency medical equipment suite can be accommodated, whereas most similar-sized helicopters can only carry one. The unobstructed cabin area and separate baggage compartment can be rapidly reconfigured to suit a range of different missions and roles. Several different cabin interiors may be adopted to accommodate different missions and operations, such as executive/VIP, EMS, and utility options; the cockpit can also be isolated from the cabin. The AW119 has been promoted as possessing the largest cabin in its class; the reported cabin volume is approximately 30% greater than other rotorcraft in its class.^[source]AgustaWestland AW119 Koala · Design; only the objects and conditions stated in this passage A wide range of avionics have been integrated upon the AW119, which are typically housed within the rotorcraft's nose. 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).^[source]AgustaWestland AW119 Koala · Design; only the objects and conditions stated in this passage 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.^[source]AgustaWestland AW119 Koala · Design; only the objects and conditions stated in this passage The TH-119 was selected as the successor of the TH-57 in January 2020, receiving the US military designation TH-73A.
