  2. Gillham code - Wikipedia

    en.wikipedia.org/wiki/Gillham_Code

    A typical altitude encoder, the ACK Technologies A-30. Note the 15-way D-type connector to send the Gillham code to the transponder and the port on the top of the case that connects to the aircraft's static pressure system. An altitude encoder takes the form of a small metal box containing a pressure sensor and signal conditioning electronics.

  3. Yakovlev Yak-25 - Wikipedia

    en.wikipedia.org/wiki/Yakovlev_Yak-25

    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.

  4. Yakovlev Yak-25 (1947) - Wikipedia

    en.wikipedia.org/wiki/Yakovlev_Yak-25_(1947)

    The Yak-25-I was given the callsign "yellow 15", and had a number "2" painted on the airbrake rudder. It was flown in factory testing by Anokhin between 31 October 1947 and 3 July 1948. [1] Flight tests followed quickly, and showed that the Yak-25 was easy to fly, and had exceptional performance and maneuverability for a straight-wing aircraft.

  5. 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]

  6. 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 ...

  7. 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.

  8. 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 ...

  9. Spacecraft attitude determination and control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_attitude...

    A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
