Avionics and Electronics Basics

This set of flashcards covers key terms and definitions related to avionics and electronic systems in aviation.

High-Frequency Radar

Radar systems utilizing high-frequency radio waves developed for communication and navigation.

NextGen

A program aimed at overhauling the National Airspace System using the latest technologies for efficient air traffic management.

Analog Electronics

The branch of electronics that deals with processing continuous signals. These systems are used to represent and manipulate real-world phenomena such as sound, light, temperature, and motion through variable electrical signals, rather than discrete values like those used in digital electronics.

Digital Electronics

Circuit systems that use discrete values, often represented as binary code, to convey information.

Noise

Unwanted alterations in the signals representing real-world phenomena, often affecting analog systems more than digital.

Vacuum Tubes

Early components used in analog circuits to control electron flow, later replaced by transistors.

Transistors

Solid-state electronic devices that act as control valves for currents, crucial in modern digital electronics.

Shock Strut

A component in landing gear systems that absorbs landing impacts and smooths out bumps during taxi.

VOR Navigation System

A very high frequency omni-directional range system for aircraft navigation using radio signals.

GPS

System using satellites to determine location, crucial for modern navigation.

ACARS

System allowing two-way communication between aircraft and ground facilities.

ELT

Type of transmitter vital for signaling a crash location in aviation.

ADF

A system used to receive signals from non-directional beacons for navigation.

TCAS

Systems installed in aircraft to alert pilots of potential traffic conflict.

WAAS

System intended to enhance GPS accuracy for aviation.

LORAN

A navigation system using radio wave pulses from a network of towers to calculate aircraft position.

Shimmy Damper

Device used in nose gear systems to control oscillation and vibration during ground operation.

Landing Gear Position Indicators

Indicators in the aircraft cockpit that show the status of landing gear positions (up, down, or in transition).

DME

Equipment used in conjunction with VOR stations to determine the distance to the station.

Digital Data Displays

Advanced displays used in aircraft to show navigational and flight data in a digital format.

Static Discharge Wicks

Devices attached to aircraft to dissipate static electricity and reduce radio interference.

Shock Absorber

Mechanism in landing gear that absorbs and dampens shock loads during landing impact.

Antenna

Device used to transmit and receive radio frequency signals in avionics systems.

Circuit Components

Various electronic parts like resistors and capacitors used in both analog and digital electronics.
