With sensor fusion, drift from the gyroscopes integration is compensated for by reference vectors, namely gravity, and the Earth's magnetic field. [3] This results in a drift-free orientation, making an AHRS a more cost effective solution than conventional high-grade IMUs that only integrate gyroscopes and rely on a high bias stability of the ...
An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
An air data computer (ADC) or central air data computer (CADC) computes altitude, vertical speed, air speed, and Mach number from pressure and temperature inputs. [1] It is an essential avionics component found in modern aircraft.
Diagram showing the face of the "three-pointer" sensitive aircraft altimeter displaying an altitude of 10,180 ft (3,100 m). Reference pressure of about 29.92 inHg (1013 hPa) is showing in the Kollsman window. An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.

Altitude awareness is crucial at all times during the jump, and determines the appropriate response to maintain safety. Since altitude awareness is so important in skydiving, there is a wide variety of altimeter designs made specifically for use in the sport, and a non-student skydiver will typically use two or more altimeters in a single jump: [6]
Fourteen Il-28s were ordered from the USSR in 1965-1966. At least twelve of them were donated to Egypt following the Six-Day War. [49] Bulgaria. Bulgarian Air Force; 14 Il-28Rs and one Il-28U received in 1955 and retired in 1974. China This is a Russian Ilyushin Il-28 'Beagle' bomber licence built in China as the Harbin (where the factory is) H-5.
A high-altitude interceptor version, the Yak-27V, was converted from the Yak-121 prototype by fitting a 1,300 kg•f (2,866 lb•f) Dushkin S-155 rocket booster in the rear fuselage, and Tumansky RD-9AKYe afterburning turbojets. Although performance was very good, reaching the height of 23,000 m (75,400 ft) during trials, development was halted ...
The Yak-120 exceeded the Air Force specific operational requirements in all aspects except for speed and range. Its 3-hour and 45 minute endurance without a drop tank (4 hours and 15 minutes with tank) and 2,800 km range on internal fuel at 12,000 m altitude allowed it to fly long-range patrols.
