The Bach Air Yacht was a trimotor airliner produced in the United States in the 1920s.
 Typical of its day, it was a high-wing braced monoplane, with fixed tailwheel undercarriage.
 Unusual for airliners of the late 1920s, (due to legislation that forbade carrying passengers in wooden aircraft), the Air Yachts were constructed almost entirely of wood with steel fittings, undercarriage and struts.
 Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft and two smaller "helpers" under the wings in nacelles supported by struts.
 As with so many aircraft companies of the late 1920s the Bach Aircraft Company succumbed to the Great Depression, thus further development of the Air Yacht was abandoned after the 3-CT-9.
Yeti Airlines Domestic Pvt. Ltd. is an airline based in Kathmandu, Nepal.
 The airline was established in May 1998 and received its Air Operators Certificate on 17 August 1998.
 Yeti Airlines is the parent company of Tara Air.
 Together, the two airlines form the largest domestic flight operator in Nepal.
 Yeti Airlines operates a fleet of seven aircraft and offers domestic flights to ten destinations.
In aviation, icing conditions are those atmospheric conditions that can lead to the formation of water ice on the surfaces of an aircraft, or within the engine as carburetor icing.
 Inlet icing is another engine-related danger, often occurring in jet aircraft.
 These icing phenomena do not necessarily occur together.
 Many aircraft, especially general aviation aircraft, are not certified for flight into "known icing"—icing conditions certain or likely to exist, based on pilot reports, observations, and forecasts.
Himalaya Airlines (Nepali: हिमालय एअरलाइन्स् , "Himālaya earalāins ") is an airline operating fromTribhuvan International Airport in Kathmandu, Nepal.
 It is the second attempt of Yeti Airlines Group to launch an international airline based in Nepal, following the collapse of Fly Yeti in 2008.
 Himalaya Airlines was founded in 2014 as a joint venture between Yeti Airlines Group, the Himalaya Infrastructure Fund and Tibet Airlines.
 It launched operations in May 2016 with a single Airbus A320.
 The airline flies to five destinations as of March 2017.
France has used many military aircraft both in its air force, the Armée de l'Air, and other branches of its armed forces.
 Numerous aircraft were designed and built in France, but many aircraft from elsewhere, or part of joint ventures have been used as well.
 Lighter-than-air aircraft such as dirigibles and balloons found use starting in the 19th century used mainly for observation.
 The advent of World War I saw an explosion in the number France's aircraft, though development slowed after.
 While having many promising designs in development in the 1930s, government wrangling delayed development enough there was little available at the out break of World War II.
 The armistice in 1940 marked a low point, with Vichy France being allowed only reduced numbers and development halting.
 Many French aircraft were captured and used by the Third Reich and its allies.
 Some aircraft that did escape served with the Allies or Free French forces, who also used many other types of allied aircraft.
 The cold-war saw the continued use of many other Western aircraft, mainly from the U.S., during a period of rebuilding of the aviation industry and under threat of war with the Soviet Union.
 Many new types would come into service including the very successful Mirage series or the latest design, the Rafale.
The Lindbergh Boom (1927–1929) is a period of rapid interest in aviation following the awarding of the Orteig Prize to Charles Lindbergh for his 1927 non-stop solo transatlantic flight in the Spirit of St. Louis.
 The Lindbergh Boom occurred during the interwar period between World War I and World War II, where aviation development was fueled by commercial interests rather than wartime necessity.
 During this period, dozens of companies were formed to create airlines, and aircraft for a new age in aviation.
 Many of the fledgling companies funded by stock went under as quick as they started as the stock that capitalized them plummeted in value following the Wall Street Crash of 1929.
 The Great Depression dried up the market for new aircraft, causing many aircraft companies to go into bankruptcy or get consolidated by larger entities.
 Air racing, record attempts, and barnstorming remained popular, as aviators tried to recapture the prizes and publicity of Lindbergh's Transatlantic flight.
Many aircraft types have served in the British Royal Air Force since its formation in April 1918 from the merger of the Royal Flying Corps and Royal Naval Air Service.
 This is a list of RAF aircraft, including all currently active and retired types listed in alphabetic order by their RAF type name.
 For just those aircraft currently in service, see List of active United Kingdom military aircraft.
 Aircraft operated with the Fleet Air Arm from 1924 until 1939 were operated by the Royal Air Force on behalf of the Navy and are included but not those operated by the Royal Navy after it re-acquired control of the aircraft used to support its operations in 1939 are not, but all aircraft operated in conjunction with the Navy are listed at List of aircraft of the Fleet Air Arm.
 Army Air Corps aircraft are not included but can be found at List of aircraft of the Army Air Corps.
No. 6 Repair Depot (6 RD) was an aircraft modification and repair unit of the Royal Canadian Air Force's Air Materiel Command located at Trenton, Ontario.
 Duties of No. 6 RD included handling aircraft at other stations around southern Ontario and assisting with aircraft being serviced or modified at other locations such as Avro where aircraft were modified for postwar use.
 No. 6RD personnel ferried many aircraft types to and from Trenton, and flew aircraft to storage facilities after the Second World War.
 Aircraft salvage was another responsibility.
 Crashed aircraft or aircraft that had forced-landed were cleaned up or dismantled to be shipped back to Trenton.
Shenyang Aircraft Corporation or Shenyang Aerospace Corporation () is a Chinese civilian and military aircraft manufacturer located in Shenyang, and is a subsidiary of AVIC.
 Founded in 1953, it is one of the oldest aircraft manufacturers in the People's Republic of China.
 Many aircraft manufacturers in China such as Chengdu Aircraft Industry Group or Guizhou Aircraft Industry Co. were founded with help from Shenyang.
 The company mainly focuses on designing and manufacturing civilian and military aircraft, as well as their related components including jet engines.
 It is also involved in the development of UAVs and drones.
A Head-on engagement is one where a surface-to-air missile system or jet aircraft engages another aircraft while the target aircraft is flying towards the attacker.
 This makes engagement with infrared homing missiles more difficult because the hot engine exhaust nozzle(s) of the target are pointing away from the attacker.
 Typically only all-aspect infra-red homing missiles are able to perform head-on engagements.
 Radar-guided missiles are typically able, however head-on many aircraft have a much smaller radar cross-section so the radar may not be able to track/lock onto the target at maximum range in this type of engagement .
