Avionics Systems Instruments

  1. 1. Avionics Systems Instruments By Michael Bseliss
  2. 2. AVIONICS The electronic systems used on aircraft, artificial satellites, and spacecraft Avionic systems include communications, navigation, the display and management of all systems that are fitted to aircraft to perform individual functions
  3. 3. 1. Basic Flight Instruments To display information about: • Heading • Altitude • Airspeed • Rate of turn • Rate of climb (or descent) • Attitude (relative to the horizon)
  4. 4. 1. Basic Flight Instruments Altimeter Indicates the aircraft’s height above a reference level (usually mean sea level)
  5. 5. 1. Basic Flight Instruments Attitude Indicator Displays the aircraft’s attitude relative to the horizon
  6. 6. 1. Basic Flight Instruments Magnetic Compass Indicates the aircraft’s heading relative to magnetic north
  7. 7. 1. Basic Flight Instruments Airspeed Indicator Displays the speed of the aircraft (in knots) relative to the surrounding air
  8. 8. 1. Basic Flight Instruments Vertical Speed Indicator Indicates rate of climb or descent (in feet per minute or meters per second) by sensing changes in air pressure
  9. 9. 2. Cabin Pressurization The crew and passengers can’t breath without the need for extra oxygen
  10. 10. 3. Air Conditioning System Human body is unable to withstand the effects of a lowpressure atmosphere, that’s why the AC and pressurization system is a vital component of modern flight
  11. 11. 4. Aircraft Fuel System Enables fuel to be loaded, stored, managed and delivered to the propulsion system
  12. 12. 5. Autopilot System An autopilot is a mechanical, electrical, or hydraulic system used to guide an aircraft without assistance from the pilot
  13. 13. 5. Autopilot System All autopilot systems contain the same basic components: 1. Gyro: To sense what the aircraft is doing. 2. Servo: To move the Flight Control Surfaces. 3. An amplifier: To increase the strength of gyro signals enough to operate the servos. 4. A controller: To allow manual control of the aircraft through the autopilot system.
  14. 14. 5. Autopilot System
  15. 15. 6. Electrical Power System Batteries are used for both aircraft startup and as an emergency source of power
