This Service Interface encompasses the different operations performed by the ATCO and modifying the Flight Plan Data. These operations can be divided in two sets of operations: the tactical instructions and the system inputs performed to modify the planed route:
- ATC tactical Instructions: Cleared To,
- System inputs: exit FL (XFL), en-route CruiseFL (ECL).
Operations
Operation to process the input of an En-Route cruise level
Operation to process the modification of a route portion for a specified flight
Operation to process the input of the Exit Flight Level used for coordination between two logical positions.
Service Interface Binding
Information is exchanged in Protobuf format. Protocol buffers or Protobuf are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data similar to XML, but smaller, faster, and simpler.
