What is the difference between fans and ATN?
The term FANS is typically linked to oceanic airspace and today includes both a Data Comm and surveillance component. On the other hand, the term CPDLC or ATN-B1 covers continental operations where, because of transponder and radar coverage, surveillance is not a requirement.
What does fans mean in aviation?
FANS (Future Air Navigation Systems) is a datalink system that lets pilots and ATC (Air Traffic Control) communicate directly, using digital text transmissions that appear on the CDU (Control Display Unit).
What is ADS C in aviation?
Automatic dependent surveillance – contract (ADS-C) uses the same systems on board the aircraft to automatically transmit similar information – aircraft position, altitude, speed, elements of navigational intent and meteorological data – only to one or more specific Air Traffic Services Unit (ATSU) or AOC  …
What does Cpdlc mean?

What does ADS-B mean in aviation?
Automatic Dependent Surveillance – Broadcast

What is difference between ADS-B and ADS-C?
ADS-B “broadcasts” reports to any station capable of receiving them. These broadcasts are automatic and continuous and are not in response to requests from ground stations (as opposed to ADS-C). ADS-C is a “contract” between the aircraft and a specific ground station.
What is VDL mode2?
VDL-M2 (Known as VDL2 or VDLM2) is a means of sending information between aircraft and ground stations. VDL Mode 2 is the only VDL mode being implemented operationally to support Controller Pilot Data Link Communications (CPDLC). An extension to the AVLC protocol permits ACARS over AVLC (AOA) transmissions.
Is CPDLC a VHF?
CPDLC can be used by itself, without ADS-C, and can be transmitted via VHF of SatCom with relatively low latency – basically the message gets where it need to go right away with practically un-noticeable delay. CPDLC text messages are entered on the flight crews CDU (control display unit) keypad.
What is a Roz?
