Is Satcom required for CPDLC?

Systems limited to U.S. domestic CPDLC DCL and en route do not require SATCOM capability. En route operations do require push-to-load capabilities. FANS 1/A+ data link operations in remote oceanic airspace are transmitted via SATCOM or VDL Mode 2 if within range of a VHF remote ground station.

What does CPDLC mean?

Controller Pilot Data Link Communications
Definition. Controller Pilot Data Link Communications (CPDLC) is a means of communication between controller and pilot, using data link for ATC communications. (

What is the difference between Acars and CPDLC?

CPDLC, as the name suggests, is for communication between pilots and Air Traffic Control, whereas ACARS is used for communication between pilots (and their aircraft) and their airline operations center, and also for general pilot operations (e.g. receiving weather reports).

What is a data link system?

In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is used to send information between aircraft and air traffic controllers for example when an aircraft is too far from the ATC to make voice radio communication and radar observations possible.

How many HF radios are required?

The second question is: “How many HF’s do I need?” The answer for a U.S. airplane used to be, very simply,”one.” But now the answer is “at least one.” The real answer is this: if you fly beyond line-of-sight radio communications, you need at least two qualified long range communications systems, of which at least one …

How do you use data link?

When using it, first toggle into the Turret UI view, aim the turret at the data point/target and then initiate the scan. Alternatively, the scan may be initiated from the cockpit without entering turret mode, but it must be linked to a Fire Group in the right panel of the SRV HUD.
