ACARS = Aircraft Communication And Reporting System

The system provides real time communication to/from aircrafts, i.e. wx-reports from ground to air or
engine readings from air to ground.

SITA / ARINC and other provide the link to/from aircrafts
via VHF

These are the basics - detailed informations would take hours to write

Hi A/C train, Buzz here. HLF-MD11 has it about right. At UAL the pilots love ACARS, they get and send all sorts of information that relates to that flight. It's a data-link that uses a VHF radio freq. to send a "beep" of data. Most of our airplanes use VHF #3.
They'll get a print of the METARS weather where they're going, transmit the passenger load, send maint. gripes, we can send a "Hey-yu" to summon a particular flight if we think the flight crew should know something, flight crews can get the gate information (where passengers connect to the next flight), and our newer airplanes automatically read/ transmit engine performance numbers for evaluation- the flight engineer used to have to write it down and we'd have to type it in.
It's just another way of sending company data, with a touch screen.
It's a VHF radio data link, no voice.... just a beeping modem sound. It's handy.
g'day

Buzz,

You should add that ACARS can also use HF and SATCOM, its not confined to VHF.

What are those "Howgozit" messages I see at work quite often?

UAL Bugsmasher...the howgosits are probably sent in error, the position report page in the FMS-CDU has two prompts, one to send the report to ATC via datalink, the other to the company. It is very easy to press the wrong one!
Just a thought  Smile/happy/getting dizzy

It's a pain in the ass when we get asked to supply football/rugby/Motor Racing etc results.

On the other hand, when an aircraft reports a problem we can download a fault report and have all the possible spares in place before the a/c arrives at its destination.

Hi UALbagsmasher, Buzz here. I don't often see the HOWGOZIT at PDX. They used to be printed up so the pilots have a paper to compare the position, time, and fuel remaining.
I didn't know that other companies use HF, or SATCOM for their Acars. We're pretty much locked into VHF.
g'day
