Avionics systems include the electronic systems used on aircraft and spacecraft to manage communications, navigation, and all other onboard systems. The document discusses six key avionics systems: 1) Basic flight instruments like the altimeter, attitude indicator, magnetic compass, airspeed indicator, and vertical speed indicator provide pilots with critical aircraft data. 2) Cabin pressurization and 3) air conditioning systems are necessary for crew and passenger safety and comfort. 4) The aircraft fuel system manages fuel storage and delivery to engines. 5) Autopilot systems use gyroscopes, servos, and controllers to automatically guide and fly aircraft without constant pilot assistance. 6) Electrical power systems use batteries for starting aircraft and emergencies.

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

4. 1. Basic Flight Instruments
To display information about:
• Heading
• Altitude
• Airspeed
• Rate of turn
• Rate of climb (or descent)
• Attitude (relative to the horizon)

5. 1. Basic Flight Instruments
Altimeter
Indicates the aircraft’s height above a reference level
(usually mean sea level)

6. 1. Basic Flight Instruments
Attitude Indicator
Displays the aircraft’s attitude relative to the horizon

7. 1. Basic Flight Instruments
Magnetic Compass
Indicates the aircraft’s heading relative to magnetic
north

8. 1. Basic Flight Instruments
Airspeed Indicator
Displays the speed of the aircraft (in knots) relative to
the surrounding air

9. 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

11. 2. Cabin Pressurization
The crew and passengers can’t breath without the need
for extra oxygen

13. 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

15. 4. Aircraft Fuel System
Enables fuel to be loaded, stored, managed and delivered
to the propulsion system

18. 5. Autopilot System
An autopilot is a mechanical, electrical, or hydraulic system
used to guide an aircraft without assistance from the pilot

19. 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.

22. 6. Electrical Power System
Batteries are used for both
aircraft startup and as an
emergency source of
power
