ACARS

ACARS - Aircraft Communications Addressing, and Reporting System
 
ACARS is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite. 
The protocol was designed by ARINC and deployed in 1978, using the Telex format. More ACARS radio stations were added subsequently by SITA.
 
ACARS messages will be send as soon as the Aircraft detect an antenna. If no antenna is detected the message will be halted and send later.

 
COM:
The airline pay ARINC/SITA per message send, to minimize the cost it is possible to bounce the acars message from the ARINC OPSCENTER or the SITA Gateway to an email account

Flight activity info
 
The data from the ACARS message will update the Flight activity window.
 
 
All received Messages are in the message section
 
 
 
Times are in the Times section
Notes:
ACARS doesn't have Delay reasons in the message. Those come from the MVT message or entered manually
The last message wins. Meaning that if MVT is received after the Acars, then the mvt times are taken.
If the Arrival messages come before the Departure message, there is a risk that the Dep message will be rejected.
 
Fuel is in the Fuel section
 
 
Down link
