Any Interest in ACARS Feed?
« on: September 25, 2005, 11:52:41 AM »
Hi all
First, CAR will be down until further notice. Grounding problems, plus I'm moving to a new place next week and have to figure out how to make a good HF antenna for the Icom.

Second, since I do have a laptop also that half the time does nothing, is anyone interested in an ACARS feed, whether HF or VHF?

Have a good weekend all

Sure, I'll listen to Missoula...why not? I don't know if you can feed an ACARS program from the sounds being transmitted over the net, but I guess it's worth the try.

Jason, no sweat. We got time.

Now the next question...ACARS; HF or VHF?

Here, I googled it for you.

It took me one mouse click and five keystrokes. Now I'll have to go take a nap--I'm exhausted!     :D

Look what I found with only five key strokes and two clicks!!! Amazing!  :lol:



What exactly is ACARS anyway? ACARS ([A]ircraft [C]ommunication [A]ddressing and [R]eporting ystem) is a digital data link system transmitted via VHF radio which allows airline flight operations departments to communicate with the various aircraft in their fleet.

This VHF digital transmission system, used by many civilian aircraft and business jets, can be likened to "email for airplanes," as the registration of each aircraft is it's unique address in the system developed by aeronautical radio giant ARINC (Aeronautical Radio, Inc.). Traffic is routed via ARINC computers to the proper company, relieving some of the necessity for routine voice communication with the company. With ACARS, such routine items as departure reports, arrival reports, passenger loads, fuel data, engine performance data, and much more,can be requested by the company and retrieved from the aircraft at automatic intervals. Before the advent of ACARS, flight crews had to use VHF to relay this data to their operations on the ground.

The ACARS system is comprised of the following elements:

1. The Airborne Subsystem, onboard the aircraft, which consists of the:

a.) Management Unit Receives ground-to-air messages via the VHF radio transceiver, and also controls the replies.

b.) Control Unit is the air crew interface with the ACARS system, consisting of a display screen and printer.

2. The ARINC Ground System, which consists of all the ARINC ACARS remote transmitting/receiving stations, and the ARINC computer and switching systems.

3. The Air Carrier C2 (Command and Control) and Management Subsystem, which is basically all the ground based airline operations such as operations control, maintenance, crew scheduling and the like, linked up with the ACARS system.

Messages can be categorized in two ways: "Downlinks" which are those ACARS transmissions which originate in the aircraft, and "uplinks" are those messages sent from the ground station to the aircraft.

A typical series of ACARS transmissions will look something like this example of United 767-300ERs departing from Washington Dulles International (IAD):

ACARS mode: 2 Aircraft reg: .N651UA
Message label: QF Block id: 1 Msg. no: M82A
Flight id: UA0978
