C295W Search and Rescue Aircraft, Canada
The Government of Canada is procuring a new fleet of 16 C295W twin turboprop fixed-wing aircraft configured for search-and-rescue (SAR) missions from Airbus Defence and Space for the Royal Canadian Air Force.
The new C295W search-and-rescue aircraft will be used to perform critical SAR duties in the North Atlantic and Arctic region and mountains.
Scheduled to be delivered between 2019 and 2022, the C295W SAR aircraft are intended to replace the Royal Canadian Air Force's existing search and rescue fleet comprising six CC-115 Buffalo and ten CC-130H Hercules aircraft.
C295W Fixed-Wing Search and Rescue Programme
Airbus Defence and Space received a prime contract award worth $2.4bn from the Government of Canada in December 2016 for the delivery of 16 C295W aircraft in a search-and-rescue configuration for the Fixed-Wing Search and Rescue (FWSAR) aircraft replacement programme.
Airbus will provide engineering, training, maintenance and in-service support services for the aircraft under the contract, which has a base period of 11 years. In addition, the company will build a new simulator-equipped training complex in Comox, British Columbia, Canada, to provide training for the C295W pilots.
Canadian-based simulation and training services provider CAE is responsible for the supply of full flight simulators.
Airbus Defence and Space, in collaboration with Provincial Aerospace, formed a joint venture designated AirPro SAR Services (AirPro) for providing repairs, upgrades and deport level maintenance for the FWSAR programme for a period of 20 years.
L-3 Wescam, a manufacturer of electro-optical sensors and targeting systems headquartered in Ontario, Canada, and Lockheed Martin Canada were selected to provide mission systems components for 16 C295W helicopters.
C295W search and rescue aircraft design and features
The Royal Canadian Air Force's C295W search-and-rescue aircraft will have a 41ft pressurised cabin with a large floor area. It is manned by two pilots, two SAR technical personnel, one flight engineer and one air combat systems officer.
The aircraft features fixed-wing design with a wing span of 25.81m and a wing area of 59m². Blended winglets are attached to the wings to improve the aircraft's operational efficiency.
The aircraft's retractable tricycle landing gear enables the flight crew to perform take-off and landing operations safely in difficult terrain conditions.
A long ramp door will be fitted in the rear of the aircraft to provide easy access for survivors, search and rescue equipment and personnel.
C295W cockpit and avionics
The C295W SAR aircraft will incorporate night vision imaging system (NVIS)-compatible cockpit and advanced avionics suite.
Featuring head-up displays (HUD) and enhanced video systems (EVS), the cockpit will provide improved situational awareness, allowing the Royal Canadian Air Force to perform search-and-rescue missions more effectively in all weather conditions.
The onboard digital avionics will provide flight safety and enhanced mission effectiveness, while reducing the pilot workload.
The aircraft will also be fitted with a FITS (Fully-Integrated Tactical System) mission system, which integrates the tactical information and mission sensors.
Sensors aboard C295W SAR aircraft
Canada's C295W SAR aircraft will be equipped with a MX-15 multi-sensor imaging system beneath its nose to localise, track, identify and detect targets in day / night and difficult weather conditions.
Developed by L-3 Wescam, the payload system can house up to six high-definition imaging and laser sensors such as laser rangefinder, laser illuminator, and electro-optical / infrared (EO / IR) cameras.
Multi-mode search radar will be fitted under the fuselage to provide an unobstructed 360° field of view. It can detect, recognise, classify and track both land and water-based objects such as fishing vessels, merchant ships, inflatable boats and small craft up to a distance of 200nm.
The SAR aircraft will also feature an automatic identification system (AIS) that is capable of transmitting and receiving text messages. The AIS is used to identify and locate aircraft, ships, land-based installations, and navigational aids with AIS transponders.
C295W propulsion details
The Canadian C295W SAR aircraft will be powered by two PWC 127G turboprop engines, rated at 2,750shp each. Manufactured by Pratt and Whitney Canada, the engines incorporate off-set reduction gearbox, reverse flow combustor, two-stage power turbine, and electronic engine control.
Mounted on the wings, each engine drives a six-blade propeller, providing high manoeuvrability and an enhanced operation in hot and high conditions.
Performance of C295W SAR aircraft
The maximum cruising speed of the C295W search and rescue aircraft is 260kt and the cruising altitude is 25,000ft. The aircraft is designed to withstand extreme variations in temperature.
