These inaccuracies a key objective is to harmonise airspace so that affect every phase of a flight as it transitions planes can fly smoothly and seamlessly across from the tower, terminal, en-route, and oceanic the globe. The objective of this best practice environments. Service providers are not guide is to assist air navigation service providers able to deliver safe, orderly, and expeditious (ANSPs) to deliver seamless service across Flight services to operators if the service is based on Information Region (FIR) boundaries; optimising erroneous flight plan data. Service providers the seamless and efficient flow of long-haul and operators are also negatively impacted international air traffic across all regions. when more than one flight plan exists that contains varying elements. In its Guide to Seamless Airspace (2013), CANSO defined seamless airspace as “contiguous The second area addresses the airspace that is technically and procedurally inefficiencies and errors that often occur when interoperable, universally safe, and in which all an aircraft transitions from surveillance to non- categories of airspace users transition between surveillance airspace, particularly due to the Flight Information Regions, or other vertical change in required separation standard. or horizontal boundaries, without requiring a considered action to facilitate that transition The guidance will help ANSPs facilitate and without any noticeable change in the type the reduction or elimination of factors that or quality of service received; air navigation contribute to operational inefficiencies, communications performance standards; or unnecessary fuel burn, CO2 emissions, and loss standard practices to be followed.” of required separation standards as aircraft cross FIR boundaries. CANSO has identified that efficiency in crossing FIR boundaries is currently impacted by This publication is intended to disparities in: separation standards; procedures complement guidance material that is already in filing flight-plans; air traffic flow management provided by CANSO’s industry partners - the (ATFM) measures; pilot-to-controller and International Civil Aviation Organization (ICAO), controller-to-controller communication capabilities; the International Air Transport Association incompatibilities between adjacent automation (IATA), and Airports Council International (ACI). platforms; and inconsistent airspace structures.

Best Practice Guide to Crossing Flight Information Region Boundaries Executive Summary CANSO Member ANSPs identified are key areas that ANSPs should consider to discrepancies in technical, equipment, improve flight plan quality. Current and emerging operational, and procedural areas as hindering technologies provide ANSPs and operators the safe, efficient, and seamless transition of air with an opportunity to reduce errors associated traffic across FIR boundaries. These identified with filing flight plans and sending movement discrepancies, which can be found in Annex A, messages. We recommend that ANSPs should were prioritised as high, medium, or low in terms implement automated data transfer systems such of impact to safety and efficiency. This CANSO as automatic message handling system (AMHS) Best Practice Guide to Flight Information Region or aeronautical fixed telecommunication network (FIR) Boundaries recommends mitigation strategies (AFTN) wherever, and whenever, possible. and best practices for two of the high priority discrepancies: filing flight plans and associated Errors and inefficiencies often occur movement messages; and the transition of in the transit of aircraft from surveillance to aircraft between surveillance and non-surveillance non-surveillance airspace in the vicinity of FIR airspace.
