Understanding Aircraft's Communication System | ACARS | Voice & Data | Antennas on an Aircraft!

How the communication system sends and receives voice and other data? on a CA first let's take a look at what is meant by a communication system in an aircraft on an aircraft the communication system is responsible for the transmission and reception of information this information may be in the form of voice in the form of data from the aircraft the system should be able to manage communication outside a graph which is from a graph to the ground station aur with another Iqra in flight it should also manage communication with the diagram which is why are the Android phone for communicating with other group members to make announcements in the cabin now let's look at the parts that are required for audio communication in a diagram communication system is centrally managed by an audio control unit this unit is responsible for receiving information from different antenna microphones and sensors it is then responsible for processing this information and transmitting them to specific locations such as headsets or speakers in the cockpit or in the cabin in the cockpit the group can manage the audio control unit with help of an audio control panel that will have different switches and knobs to transmit or receive information.

The audio control unit information from different sources such as the intercom that is used for internal communication it will also receive audio information from the communication for navigation radio from the ground stations it may also be linked to some critical systems in their grant in order to Trigger onboard alerts in case of failures after processing the received data the What data is sent to speaker or had them for the group members this unit will also send all the audio data the cockpit voice recorder continuously records all this information the audio control unit allows the flight to select and control the received audio from this panel that group mein select me or adjust channel for communicating with the ground station as required they can also select group intercom for communicating with other crew members what select the system to address the passengers the audio control panel also has switches that can be used to turn the system on or off auto adjust the volume in the headset for the speakers and for transmission of audio over the selected channel now let's look at how data communication takes place from the anchor in most modern and car is installed distance for a graph communication addressing and reporting system this is responsible for receiving and transmitting data from the aircraft

the acres prevents the digital data link for the aircraft this is used to send specific information to different stations on the ground the data that is sent is taken from different graph sensors or systems and is transmitted via HF or VHF depending on their graphs position the recording sense or refuse data from the ATC for particular airspace it could also send information to the airline operations control for efficient management of the airline fleet and personal for the smooth operation of all the aircraft the acres sales data such as the aircraft position the aircraft system status for any failures that occurred weather later information and diversion information if required

10+ Incredible Facts About The HAL TEJAS Fighter Jet

in the corporate that group can manage and monitor the data that is sent on the 1 hours with the help of the control and display unit or CDU the CDU is the only unit which provides an interface to the group for sending information or receiving data so the seed you provide access to information transmission information automatically or manually if required and also has a provision for sending text messages to the ground control for the communication system to send Odyssey voice data signals shuttle Antennas are installed on the aircraft  will have VHF communication 1 which is normally used for voice communication and we nature communication to which is kept on standby and used for monitoring purposes only the aircraft may have his communication three which is used along with header for data transmission for a cause the aircraft will also have a transponder for 80c and voice recorder for CVR installed at the tail so section pause that light communication that come may be installed on some aircraft
