  2. Pressure altimeter - Wikipedia

    en.wikipedia.org/wiki/Pressure_altimeter

    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]

  3. Attitude and heading reference system - Wikipedia

    en.wikipedia.org/wiki/Attitude_and_heading...

    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 ...

  4. Air data computer - Wikipedia

    en.wikipedia.org/wiki/Air_data_computer

    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.

  5. Air data inertial reference unit - Wikipedia

    en.wikipedia.org/wiki/Air_data_inertial...

    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 ...

    en.wikipedia.org/wiki/Yakovlev_Yak-52

    The Yakovlev Yak-52 (Russian: Яковлев Як-52) is a Soviet primary trainer aircraft which first flew in 1976. It was produced in Romania from 1977 to 1998 by Aerostar , as Iak-52 , which gained manufacturing rights under agreement within the former COMECON socialist trade organisation. [ 1 ]

    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.

    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.

    en.wikipedia.org/wiki/Yakovlev_Yak-11

    The first prototype of the new trainer, designated Yak-UTI or Yak-3UTI flew in late 1945. It was based on the radial-powered Yak-3U, but with the new Shvetsov ASh-21 seven-cylinder radial replacing the ASh-82 of the Yak-3U. [2] [nb 1] It used the same all-metal wings as the Yak-3U, with a fuselage of mixed metal and wood construction. The pilot ...
