While it is arguably the most competitive part of the helicopter market, the light-single segment is not necessarily blessed with the most modern designs. The biggest seller is Airbus Helicopters' H125, which dates back to 1975 and the Aerospatiale era - reflected by its original AS350 designation. The design has been through numerous iterations since that time, however, with the latest tweaks unveiled by the manufacturer aimed specifically at the utility work segment. At the heart of the upgrade is a power increase for the H125's Safran Helicopter Engines Arriel 2D turboshaft, with maximum output rising to 952shp (710kW), from 847shp. This in turn boosts maximum external load to 1,140kg (2,15Olb): a 140kg increase from the current limit, while the type's hover ceiling rises by 1,490ft, to 12,640ft. However, if BLR Aerospace's FastFin modification is also fitted, these increases grow to 190kg and 2,300ft, respectively. Approval for the changes is still awaited.
