The S-92A's avionics have considerably modernised the Irish Coast Guard’s SAR fleet.
Teamwork is essential when operating from fields and mountains or in confined areas.
The Panasonic Toughbook Ordnance Survey and Admiralty Chart-based moving map is linked to the radar and the FLIR.
The Mi-171 A2’s rotor hub and blades were derived from those fitted to the Mi-38.
The S-76A++s used by CHC Helicopters on the SAR contract are equipped with a rescue winch on the starboard side of the cabin, while some of the fleet (including this example) have a nose mounted FLIR turret.
S-76A VH-LRP (c/n 760122) was built in 1980 and delivered as N176CH, before being acquired by Lloyd Helicopters in 1988 prior to that company becoming part of CHC in 1999.
S-76A VH-LHN (c/n 760300) was registered to CHC Helicopters in May 2003.
The SBGS EC135T2s each have a FLIR Systems UltraFORCE 2 and a Nightsun searchlight mounted on the nose.
The forward-looking infrared sensors are used to detect criminals at night or in dense woodland.
Two EC120Bs were the first modern helicopters that arrived on the SBGS Aviation Unit more than a decade ago.
An attractive payload/range capability and a considerable increase in the cruise speed are promised for the Mi-171A2 due to the all-new rotor system and more powerful and fuel-efficient engines.
The Mi-171 A2’s rotor hub and blades were derived from those fitted to the Mi-38.
The current production-standard Mi-171A (this one is operated by UTair) is now regarded as an ageing design and Russian commercial operators have raised requirements for a more modern aircraft featuring a rapidly re-configurable cabin and a type certification in accordance to European and US airworthiness requirements.
The X-shaped tail rotor provides better efficiency and produces 20% less noise.
A forward-facing KOS-17 camera, mounted in the nose of the helicopter, covers a 120° arc in the horizontal plane for enhanced situational awareness.
Only minor cosmetic changes were made from the Mi-171's external layout to reduce development time and costs.
Pall intake filters are intended to provide reliable operation and save the engines from wear and tear in dusty and sandy conditions.

Compared to its predecessor, the Mi-171A2’s fuselage structure is almost the same with the only difference being a reinforced floor in order to allow installation of crash-resistant passenger seats.
Four 6x8 in LCD screens show flight/navigation and system information and a central 15 in display provides digital map information or video images derived from the enhanced visibility system.
