Rotary Wing Test and Evaluation Squadron

Typical work

Any new aircraft, new equipment or modification for use in British military aircraft needs to be safe to be flown in the intended role and effective at prosecuting that role. RWTES personnel are responsible for planning, executing and reporting flight test trials for the Royal Navy, British Army and Royal Air Force. Typical trials include assessment of performance, flying qualities, airworthiness, systems and safety modifications. Recent examples are:

• Bringing new aircraft into service;
• Mid-life upgrades to in-service aircraft;
• Improved night vision devices;
• Improvements to aircraft performance;
• Updated Defensive Aids Suites;
• New radios and other communication devices.

Trials involving new aircraft major modifications to in-service aircraft are conducted in Combined Test Teams with representatives from the manufacturer (e.g. AgustaWestland), RWTES, QinetiQ, and the Operational Evaluation Unit (OEU) of the Arm or Service (e.g. the Royal Navy's Lynx OEU).

Aircraft

RWTES have use of a number of aircraft, permanently based at Boscombe Down, including 2 Sea King, and 4 Gazelles.^[2] The longest serving of which is Gazelle HT3 XZ936, commissioned in May 1978 and living its entire life at Boscombe Down. Two of the Gazelles are painted in the classic A&AEE colours of red, white and blue; they are used for continuation training and trials work as well for instruction use by ETPS. One Sea King is an "instrumented" HC4 Junglie and the other is an uninstrumented HU5. Flight test instrumentation (FTI) is fitted to some aircraft to accurately measure parameters including performance, sideslip, 'G' and control activity.

Additional military aircraft are allotted to Boscombe Down for specific trials; including the

Training

In 1914 the Experimental Flight was established at Upavon to assess the new aeroplanes and their equipment for this revolutionary new means of warfare. The Experimental Flight expanded in the inter-war years and in 1943 a dedicated school was set up by Air Marshal Sir Ralph Sorley, the controller of Research and Development, as he was concerned by the rising number of fatalities in test flying and a lack of standardisation of flying techniques. The Test Pilots' Training Flight at Boscombe Down was formed, now called the Empire Test Pilots School, one of a succession of schools with the Empire prefix.^[3] It served the Air Forces of the British Empire and has been attended by experienced pilots from around the world.

Working alongside QinetiQ

The MOD conducts its flight test and military evaluation activities in a public-private partnering arrangement with QinetiQ. The Armed Forces provide specialist personnel to work in partnership with QinetiQ. For regulatory purposes the QinetiQ-MOD partnering arrangement that is approved to conduct flight testing is referred to as the Air Test and Evaluation Centre (ATEC).
