Thales Avionics is to supply the TopOwl Helmet Mounted Sight and Display (HMD), also fitted on the Tiger, NH90 and Rooivalk helicopters. The flight controls include conventional cyclic, collective and directional pedals.Įach crew station has two 8in×8in active matrix liquid crystal colour multifunction displays and a 4.2in×4.2in dual function display and data entry keyboard on the central console. The two crew stations are nearly identical with pilot or copilot functions at either station. The new fully integrated glass cockpit is night vision goggle compatible. The gantries can be stowed in two positions so the cabin can be configured for ten crashworthy seats or six litters. Two fast rope gantries, deployable from within the cabin, are permanently installed. The system is capable of folding and unfolding in horizontal winds up to 45kt from any direction. “UH-1Y missions include airborne command and control, and search and rescue.”īlade folding is by a combination of automatic and manual procedures. The first production UH-1Y was delivered in January 2007. The third LRIP contract for seven UH-1Ys was placed in July 2006. One UH-1Y was delivered to the USMC in October 2005.ĭevelopmental testing was completed in February 2006 and a six-month operational evaluation (OPEVAL) began in May 2006. An LRIP order for six UH-1Y was placed in December 2003 and a second batch of four LRIP aircraft was ordered in April 2005. The first flight of the UH-1Y took place in December 2001 and first flight of the fully configured aircraft was in October 2003. The helicopters have a common four-bladed, composite, hingeless, bearingless main rotor system and tail rotor, engine, avionics, software, controls and displays. The UH-1Y and AH-1Z have a very high level of commonality which reduces the manufacturing and procurement costs. This strategy was preferred because of the increase in operational deployment following Operation Iraqi Freedom, the marginal cost difference and the adverse impact of having helicopters out of commission during the upgrade process. “The UH-1Y helicopter is fully marinised and capable of shipboard operations worldwide.”
