The Sukhoi Su-26 is a single-seater aerobatic aircraft from the former Soviet Union , powered by a single radial reciprocating engine . The Su-26 has mid-mounted straight wings and fixed landing gear, the main gear mounted on a solid titanium arc.
8-522: The Su-26 made its first flight in June 1984, the original four having a two-bladed propeller. The production switched to the Su-26M, with refined tail surfaces and a German-made MTV-9 3-blade composite propeller. Further refinements were made, and the model won both the men's and women's team prizes at the 1986 World Aerobatics Championships. The modified Su-26M3 with the new M9F 320 kW (430 hp) engine dominated
16-478: Is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry , which is related to the term bathymetry , the measurement of depth under water. In 1931, the US Army Air Corps and General Electric tested a sonic altimeter for aircraft, which was considered more reliable and accurate than one that relied on air pressure when heavy fog or rain
24-467: Is used to help navigate the helicopter Ingenuity on its record-setting flights over the terrain of Mars by means of a downward-facing Lidar altimeter. Global Positioning System (GPS) receivers can also determine altitude by trilateration with four or more satellites . In aircraft, altitude determined using autonomous GPS is not reliable enough to supersede the pressure altimeter without using some method of augmentation . In hiking and climbing, it
32-448: The 2003 and 2005 Aerobatic World Championships as well as the 2004 European Championships. The Su-26 has fully metric instruments, except for the altimeter .

Nevertheless, when
40-417: The frequency shift the further the distance travelled. This method can achieve much better accuracy than the pulsed radar for the same outlay and radar altimeters that use frequency modulation are industry standard. The radar altimeter is used to measure height above ground level during landing in commercial and military aircraft. Radar altimeters are also a component of terrain avoidance warning systems, warning
48-591: The game was still under development, the Sukhoi Su-26 had been promised as a bonus flyable aircraft for all players, but was not included in the game upon release in March 2011. It was finally included as downloadable content with the adjunction of the Steam patch 1.11.20362 on 19 October 2012.

56-446: The pilot if the aircraft is flying too low, or if there is rising terrain ahead. Radar altimeter technology is also used in terrain-following radar allowing combat aircraft to fly at very low height above the terrain. After extensive research and experimentation, it has been shown that "phase radio-altimeters" are most suitable for ground effect vehicles , as compared to laser, isotropic or ultrasonic altimeters. Lidar technology
64-478: Was present. The new altimeter used a series of high-pitched sounds like those made by a bat to measure the distance from the aircraft to the surface, which on return to the aircraft was converted to feet shown on a gauge inside the aircraft cockpit. A radar altimeter measures altitude more directly, using the time taken for a radio signal to reflect from the surface back to the aircraft. Alternatively, Frequency Modulated Continuous-wave radar can be used. The greater
