Key findings, recommendations for next steps and future work

Annex 1 Definitions used in the Focus Group Deliverables

1.1 adiabatic quantum computer (based on quantum annealing) (Deliverable 1): Computation decomposed
into a slow continuous transformation of an initial Hamiltonian into a final Hamiltonian, whose ground states
contains the solution.

1.2 aeronautical mobile-satellite (route) service (AMS(R)S) (Deliverable 4): An aeronautical mobile-satellite
service reserved for communications relating to safety and regularity of flights, primarily along national or
international civil air routes.

1.3 aircraft communications addressing and reporting system (ACARS) (Deliverable 2&3 and 4): A digital
data link system for transmission of short messages between aircraft and ground stations via air band radio
or satellite. The protocol was designed by Aeronautical Radio, Inc. (ARINC) and deployed in 1978, using the
Telex format.

1.4 aircraft condition monitoring system (ACMS) (Deliverable 2&3 and 4): ACMS collects performance data of
various systems in the aircraft. Most reports are related to the engines, with reports such as take-off report,
engine stable report or sink rate report. The reports are typically transmitted via the aircraft communications
addressing and reporting system (ACARS).

1.5 aircraft control domain (ACD) (Deliverable 4): ACD consists of systems and networks that support the
safe operation of the aircraft, based on digital data networks. The justification for most of these systems
is traceable to the safety of the flight. It may also provide services and connectivity between independent
aircraft domains such as the aircraft information services domain (AISD), and the passenger information and
entertainment services domain (PIESD), cabin distribution network and any connected off-board networks.
In general, systems within ACD should always protect themselves. A complicating factor for ACD is that, while
all air transport aircraft may be assumed to have ACD, there is a tremendous variety of systems and network
architectures used in avionics. This means that characteristics internal to the domain can only be described
in general terms.

1.6 aircraft information services domain (AISD) (Deliverable 4): AISD may provide services and connectivity
between independent aircraft domains such as avionics, in-flight entertainment, cabin distribution and any
connected off-board networks. It provides general purpose routing, computing, data storage and a security
perimeter between AISD and less critical domains and any connected wireless networks. It may be comprised
of one or more computing platforms for third-party applications and content and may be used to support
applications and content for either cabin or flight crew use.

1.7 aircraft interface device (AID) (Deliverable 4): Discrete devices or avionics interface functions hosted in
other avionics systems that are designed to safely provide flight data and connectivity services to other less
critical or non-certified systems such as installed or portable electronic flight bags (EFBs).

1.8 aircraft surveillance (Deliverable 4): Provides the aircraft position and other related information to air
traffic management and/or airborne users for the purpose of aircraft separation.
1.9 aircraft tracking (Deliverable 4): A ground-based process that maintains and updates, at standardized
intervals, a record of the four dimensional position of individual aircraft in flight. Aircraft tracking may be
used for progress monitoring of the flight, to provide immediate notification when an aircraft experiences an
abnormal event, and in case of an accident, to enhance the ability to rescue survivors.

1.10 airline administrative communications (AAC) (Deliverable 4): AAC includes information regarding
administrative aspects of the airline business such as crew scheduling and cabin provisioning. Examples are
passenger lists, catering requirements and baggage handling. Non-safety related communications include AAC
and airline passenger correspondence (APC).
1.11 airline operational communication (AOC) (Deliverable 2&3 and 4): The AOC communications encompass
all aircraft flight operations, maintenance and engineering. It involves the information exchange between the
aircraft and the airline operational centre or operational staff at the airport associated with the safety and
