The Z-11 is a light utility helicopter designed for training and liaison missions. two batches of Z-11s are in service at the army Aviation training school. Developed by CHAIC and 602 Institute, Z-11 passed the certification in December 1996 and the first batch were delivered to the army Aviation in August 1998. Compared to Z-9, it weighs less (2,200kg) and is powered only by one WZ-8D turbo-shaft engine (rated @ 510kW) rather than two. Its most speed is 278km/h, service ceiling 5,240m, max range 598km, endurance 3.9hr.
It seems that Z-11 was truly based on French AS-350B Squirrel, 7 of that are in service with the army Aviation (S/N LH904XX). A scout version just like US Army OH-58D was developed and dubbed Z-11WA. This variant features a roof-mounted all-weather TV/IIR sight and an NVG compatible cockpit. It can be armed with 57mm unguided rockets, 12.7mm machine gun pod and up to 4 KD-8 ATGMs.
The first prototype of Z-11WA flew on December 27, 2004. but this version didn't attract any order from the army and instead a number of Z-9WZ were acquired. Recent pictures indicated that Z-11 has been carrying a military camouflage. the latest news (October 2011) suggested that China and Argentina signed an agreement to assemble CZ-11W scout helicopter in Argentina aiming at the entire South american market.
