Ads-C Agreement

Posted on

Automatic Dependent Surveillance – Contract (ADS-C): ways to exchange the terms of an ADS-C agreement on a data connection between the ground system and the aircraft, which defines the conditions under which ADS-C reports are initiated and the data contained in the reports. (ICAO) Note. – According to paragraph of ICAO Doc 4444, the WCE, LRDE and LDE are included at least in ADS-C agreements in the airspace where the separation of procedures is applied. An ADS contract is an agreement between you, the pilot, with the Air Traffic Service (ATS) to provide information. You can provide information on different types of contracts and do so with up to four different ATS providers. The data is automatically extracted from different electronic parts on your aircraft. In exchange, they give you access to the airspace you are in or coordinate with nearby airspace. ADS-C will replace reports on language positions in many parts of the world. You need special equipment and permission to use ADS-C.

In concrete terms, the report indicates that the FAA has decided to continue to improve ADS-C in the short term, as efficiency gains for airspace users have exceeded the cost of increasing location reports and upgrading the air traffic control system by 2 to 1. In contrast, the FAA found that the cost of using ADS-B in U.S. ocean airspace outweighs efficiency gains of 6 to 1. Note: Flight crew and officers/dispatchers should not use ARINC 424. ARINC 424 describes a 5-digit latitude/longitude format for aircraft navigation databases (z.B. 10N40 describes a 10N140W lat/long). The ATS unit may or may not process a top-down link message containing point names in ARINC 424 format. The U.S. government recently released a report outs setting out the Federal Aviation Administration`s (FAA) commitment to use enhanced dependency surveillance technology (ADS-C) in U.S. ocean airspace as part of its commitment to implement new international standards by 2022. In general, you should not provide position reports or revisions to CPDLC or Voice point of passage estimates, unless you see something that tells you that.

Adding B can be misleading. The issue is addressed only in the North Atlantic, where you are specifically told: „In the case of ADS-C flights, the flight crew should not submit position reports by vote to reduce congestion, unless required by the air radio.“ It makes sense, but don`t get you to think now that you have to do it in other regions because there is not the same sentence.
