What does ACARS mean in OCEAN SCIENCE

ACARS (ARINC Communications Addressing and Reporting System) is a digital communications system used to send short messages and data between aircraft and ground stations. It enables pilots to receive critical weather, equipment maintenance, and other information on their aircraft.

ACARS uses VHF radio transmissions to send data to and from an aircraft. The system essentially works like a satellite phone by connecting an aircraft to a global network that links it with the ground stations. This allows for the transmission of short messages and other data such as email messages, flight plans, weather display images, aircraft performance information, maintenance reports, navigation guidance, etc.

Through the ACARS system, operators are able to perform functions such as sending operational telexes (OTXs), giving meteorological updates (METs), requesting maintenance status information (MELs) or even transmitting crew-written reports (CWRs). Additionally, airline companies are able to use ACARS to monitor their operations from takeoff through landing.

There are two different frequencies that can be used for ACARS transmissions—VHF channels 31 & 32—which operate in the 118-136 MHz range. Both frequencies are reserved exclusively for aeronautical communications purposes by the Federal Communications Commission (FCC).

Private pilots may not have access to all of the capabilities of an aviation authority certified system but they can take advantage of some of the more basic features that enable them to stay connected with their base station while flying. The main purpose of these systems would be limited primarily to maintaining contact with air traffic control centers or providing general communication between two points on the same frequency without having access to flight logs or other advanced features.

Yes. As mentioned before only certain frequencies are allowed for use by ACRS systems so you will need specialized avionics onboard your aircraft — either certified or private — in order to include this functionality on your flight operations. The most common piece of equipment required is a transceiver which comes in both Low Frequency (LF) and Very High Frequency (VHF) models so it's important that you make sure you have the correct type installed before attempting any transmissions or receptions with your chosen airline provider.

Generally speaking most airlines do not charge additional fees for using an aircraft's onboard ACARs; however some carriers do reserve the right to charge nominal fees if certain services such as route updates or weather monitoring are used more frequently than normal usage patterns anticipate. Always check with your carrier regarding any extra costs associated with incorporating this technology into your plane's operations.

An onboard Acars system enables you retrieve a wide array of information including updated air traffic control restrictions/instructions, current weather radar/forecast data, up-to-date NOTAM notifications, along with fuel request authorization forms prompting you when refueling needs occur. You may also access critical hardware/software support files, specialized electronic charts showing terrain heights/airways designations, Embraer specific advisories allowing subscribers instant access whenever notifications appear requiring attention.
