A-CDM Data Feed

What is it?

The A-CDM Data Feed service provides customers with active flight data for aircraft landing and taking off from Heathrow. Customers can build their own applications to support their operations at Heathrow.

With the implementation of the A-CDM Data Feed, Heathrow has enabled businesses at the airport to automate their processes, thus delivering a better quality of service to passengers.

What do we offer?

A customer subscribes to the service by establishing a connection to an end point provisioned as part of a network design. This connection is then configured to contain flight information about the airlines the customer requested at set up. Data is delivered as an XML stream that conforms to Heathrow’s Common Information Model. Customers will be provided with Java and .Net APIs for connections.

The service is provided by Heathrow via its Flight Publish service on the Enterprise Service Bus (ESB). Both are available today.

How much does it cost?

  • The customer is charged for testing and service connection, project management and customization. Once service connection testing is successfully completed, connection will be allowed against the production service, and then handed over to support.
  • Project services cost £12,000 including Network design and deployment.

Requesting the service

  • Access request is via the Heathrow Commercial Telecoms ordering portal www.heathrow.com/telecoms
  • Once the request is approved the customer will be provided with technical details on how to connect to the service.
  • Additional work is required by Heathrow and the customer’s IT team, who will need to provide a subscribing client application.
  • The subscribing customer must pass some basis tests in a test environment before they can be connected to the production environment. Heathrow will then be assured that the subscribing customer will not cause any issues on the Heathrow side of the connection. For example the customer can process the right volume of flight update messages in a timely fashion.
