Question 1

What are avionics?

pfleming33 · Accepted Answer

Aviation and electronics join to form the word avionics - basically it is equipment that is installed in aircraft or spacecraft to conduct hundreds of mission and flight management tasks, such as navigational systems, engine controls, flight control systems, communications, weather radar, lighting systems, threat detection, fuel systems, and performance monitors.

Various types of electronic systems are employed in modern aircraft, spacecraft, and artificial satellites in order to accomplish their purpose and mission. As a general rule, the more complex the craft or mission, the more complex the electronic systems employed.

Commercial airliners, helicopters, military fighter jets, unmanned aerial vehicles (UAVs), business jets, and spacecraft all rely on avionics to perform functions, complete missions, conduct research, monitor performance, and ensure safety requirements are met. As well as improved performance and maintenance, advanced avionics systems integrate multiple functions.

Question 2

What does fly-by-wire mean?

pfleming33 · Accepted Answer

FBW systems replace mechanical flight controls with an electronic interface to provide semi-automatic, computer-controlled flight control of aircraft.

In response to the pilot’s movements, the aircraft’s flight control computers (FCCs) interpret those signals and adjust actuators that move the flight control surfaces. Sensors throughout the aircraft are also monitored by computers so that automated adjustments can be made to ensure the best possible flight. Using sensor data from active control sticks, the FCC creates “tactile cueing”, which provides pilots with tactile feedback. They sense how the aircraft is moving and how its aerodynamic limits are affected by the FCC.

Pilots move levers, rods, cables, pulleys, and more in traditional mechanical and hydro-mechanical flight control systems to change control surfaces according to aerodynamic conditions. Pilots are able to direct, tactilely feel how the aircraft is handle aerodynamic forces while flying with their “hands on” design. Additionally, mechanical systems are bulky, heavy, and require frequent maintenance, are difficult to use, and require constant monitoring.

Fly-by-wire is also lighter and less bulky than mechanical controls, which can increase fuel efficiency and allow for more flexible aircraft designs, even in legacy aircraft. Additionally, most fly-by-wire systems come with triple or quadruple redundancy back-ups to prevent flight critical failures. Fly-by-wireless, fly-by-optics, power-by-wire, and other innovations are also in development for the system.

Question 3

What is a Primary Flight Display (PFD)

pfleming33 · Accepted Answer

The Primary Flight Display (PFD) is an instrument which integrates and depicts, on a single display, all of the information that was historically presented on a number of individual electromechanical instruments. The PFD has evolved from a basic attitude indicator/flight director combination, presented electronically on a CRT, to an Electronic Attitude Direction Indicator (EADI) which, variable by manufacturer, added additional information such as heading, altitude and airspeed.

The modern PFD displays virtually all of the information that the pilot requires to determine basic flight parameters (altitude, attitude, airspeed, rate of climb, heading, etc) plus autopilot and auto-throttle engagement status, flight director modes and approach status. Depending upon the phase of flight and pilot selections, the flight director will provide appropriate lateral guidance to maintain the selected track, heading or approach and missed approach track and vertical guidance for climb and descent, level off, approach and missed approach. This greatly reduces pilot workload while in manual flight and facilitates flight monitoring with the autopilot engaged as all required information is displayed on a single instrument. Skybrary

Question 4

What is ADS-B?

Peter Fleming · Accepted Answer

Automatic Dependent Surveillance–Broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system.

The system involves an aircraft with ADS-B determining its position using GPS. A suitable transmitter then broadcasts that position at rapid intervals, along with identity, altitude, velocity and other data. Dedicated ADS-B grounds stations receive the broadcasts and relay the information to air traffic control for precise tracking of the aircraft.

Automatic - Requires no pilot input or external interrogation.
Dependant - Depends on accurate position and velocity data from the aircraft's navigation system (eg. GPS).
Surveillance - Provides aircraft position, altitude, velocity, and other surveillance data to facilities that require the information.
Broadcast - Information is continually broadcast for monitoring by appropriately equipped ground stations or aircraft.

ADS-B data is broadcast every half-second on a 1090MHz, digital data link.

Broadcasts may include:

Flight Identification (flight number callsign or call sign)
ICAO 24-bit Aircraft Address (globally unique airframe code)
Position (latitude/longitude)
Position integrity/accuracy (GPS horizontal protection limit)
Barometric and Geometric Altitudes
Vertical Rate (rate of climb/descent)
Track Angle and Ground Speed (velocity)
Emergency indication (when emergency code selected)
Special position identification (when IDENT selected)

The ability of a ground station to receive a signal depends on altitude, distance from the site and obstructing terrain. The maximum range of each ground station can exceed 250 nautical miles. In airspace immediately surrounding each ground station, surveillance coverage extends to near the surface.

Question 5

What is an Electronic Flight Instrument System (EFIS)

pfleming33 · Accepted Answer

An Electronic Flight Instrument System (EFIS) is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical.

A typical EFIS system comprises a Primary Flight Display (PFD) (Electronic Attitude Direction Indicator (EADI)) and an Electronic Horizontal Situation Indicator (EHSI) (Navigation Display). In some designs the two displays are integrated into one. Skybrary

What is an Electronic Horizontal Situation Indicator (EHSI)

pfleming33 · Accepted Answer

The Electronic Horizontal Situation Indicator (EHSI), often referred to as the Navigation Display (ND), replaces a number of different instruments found on a conventional aircraft instrument panel, and may be used to depict some or all of the following information:
