8 RADOME RAdar DOME is an aerodynamic faring that houses the weather radar and ILS localizer and glide- slope antennas. Unlike the rest of the fuselage it is made of fiberglass to allow the RF signals through.

9 Audio Control Panel

10 Antennae

11 Avionics Systems Nav Radio: Used to tune VORs, ILS, & GLS.
Marker Beacons: Pre-tuned to given frequency and illuminate when overflown. SELCAL: Can alert the crew that a ground radio station needs to communicate with the aircraft. Cockpit Voice Recorder Service Interphone: For calls with maintenance

12 Avionics Systems Transponder: Transmitter-responder, responds when receiving a radio-frequency interrogation. Used for aircraft identification by ATC radar. Emergency Locator Transmitter (ELT)

18 What is avionics ? Avionics are the aviation electronics systems
that provide the functions and capabilities required for safe operation of aircraft throughout the world. Avionics encompass the ground, aircraft, and space assets required for control of flight of the aircraft, and its operation and movement while on the ground. Training systems incorporate avionics used in the aircraft.

19 Aircraft Avionics The air traffic control system is a global network of national air traffic control systems that seamlessly pass the control of international flights as they travel between countries and continents. Air traffic control globally coordinates the use of airspace. Airspace capacity is influenced by weather conditions and bad weather at landing or takeoff airports creates backups, delays, and cancelled flights.

20 Aircraft Avionics The avionics onboard an aircraft provides the crew the capability to manually or automatically control the flight of the aircraft in response to flight plans and air traffic control clearances. Avionics also provide passenger entertainment in airline operations. Avionics systems integrate the hardware and software that implement control of flight functions, navigation, guidance, control, communications, and systems operations and monitoring.

21 Aircraft Avionics Technology advances rapidly and many avionics developments such as the Global Positioning System (GPS) have contributed to the economy by creating an industry that provides products with applications from the original navigation to surveying, construction, transportation, logistics, and recreational usage.

22 Advanced Avionics Pilots now have an unprecedented amount of information available at their fingertips. Electronic flight instruments use innovative techniques to determine aircraft attitude, speed, and altitude, presenting a wealth of information in one or more integrated presentations. A suite of cockpit information systems provides pilots with data about aircraft position, planned route, engine health and performance, as well as surrounding weather, traffic, and terrain.

23 Advanced Avionics Advanced avionics systems can automatically perform many tasks that pilots and navigators previously did by hand. For example, an area navigation (RNAV) or flight management system (FMS) unit accepts a list of points that define a flight route, and automatically performs most of the course, distance, time, and fuel calculations. Once en route, the FMS or RNAV unit can continually track the position of the aircraft with respect to the flight route, and display the course, time, and distance remaining to each point along the planned route. An autopilot is capable of automatically steering the aircraft along the route that has been entered in the FMS or RNAV system.

24 Advanced Avionics Advanced avionics perform many functions and replace the navigator and pilot in most procedures. However, with the possibility of failure in any given system, the pilot must be able to perform the necessary functions in the event of an equipment failure. Pilot ability to perform in the event of equipment failure(s) means remaining current and proficient in accomplishing the manual tasks, maintaining control of the aircraft manually (referring only to standby or backup instrumentation), and adhering to the air traffic control (ATC) clearance received or requested.

25 Advanced Avionics Pilots of modern advanced avionics aircraft must learn and practice backup procedures to maintain their skills and knowledge. Risk management principles require the flight crew to always have a backup or alternative plan, and/or escape route. Advanced avionics aircraft relieve pilots of much of the minute-to-minute tedium of everyday flights, but demand much more initial and recurrent training to retain the skills and knowledge necessary to respond adequately to failures and emergencies.

26 Advanced Avionics The FMS or RNAV unit and autopilot offer the pilot a variety of methods of aircraft operation. Pilots can perform the navigational tasks themselves and manually control the aircraft, or choose to automate both of these tasks and assume a managerial role as the systems perform their duties. Similarly, information systems now available in the cockpit provide many options for obtaining data relevant to the flight.
