Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).

Part 13:
Training devices
1 Scope
This document defines terms used in the field of pilot training with the use of technical equipment,
called flight simulators, enhancing safety by allowing pilots to practice various scenarios in a controlled
environments, without the need of an actual aircraft.
This document establishes the terms and definitions of the basic concepts applied in science, engineering
and manufacturing in the field of flight simulation training devices (airplane and helicopter).
2 Normative references
There are no normative references in this document.
3 Terms and definitions

3.1 Categories
3.1.1
flight simulation training devices
FSTD
technical system designed to replicate the experience on flying an aircraft in various scenarios in a
controllable environment without the need for an actual aircraft
3.1.2
full flight simulator
FFS
FSTD (3.1.1), equipped with a full size replica of a specific type, model and series aircraft flight deck, including
the assemblage of all equipment and computer programs necessary to represent the aircraft in ground and
flight operations, normal, abnormal and emergency procedures throughout the full flight envelope
Note 1 to entry: FFS (3.1.2) includes all flight and basic aircraft systems, a visual system providing an out of the flight
deck view, acoustic system providing sound cues and a force cueing motion system.

3.1.3
navigation and weapon systems trainer
NWS
FSTD (3.1.1), equipped with a full size replica of aircraft instruments, panels, equipment and controls, in
an open cockpit area, including all equipment and computer programs necessary to represent the aircraft
in ground and flight conditions to the extent of the navigation and weapon systems (NWS) installed in the
device
Note 1 to entry: For NWS (3.1.3), no motion cueing system is required.
3.1.4
flight training device
FTD
FSTD (3.1.1), equipped with a full size replica of a specific aircraft type’s instruments, equipment, panels and
controls in an open flight deck area or an enclosed aircraft flight deck, including the assemblage of equipment
and computer software programs necessary to represent the aircraft in ground and flight conditions to the
extent of the systems installed in the device
Note 1 to entry: For FTD (3.1.4), no force cueing, motion cueing or visual system is required.
3.1.5
cockpit procedure trainer
CPT
FSTD (3.1.1), equipped with a full size replica of aircraft instruments, panels, equipment and controls, in an
open cockpit area, including all equipment and computer programs necessary to represent the aircraft in
ground and flight conditions to the extent of the systems installed in the device, including mission systems
Note 1 to entry: For CPT (3.1.5), no motion cueing or visual system is required.
3.1.6
flight and navigation procedures trainer
FNPT
FSTD (3.1.1), equipped with flight deck or cockpit environment including the assemblage of equipment and
computer programs necessary to represent an aircraft in flight operations to the extent that the systems
appear to function as in an aircraft
3.1.7
basic instrument training device
BITD
ground based FSTD (3.1.1), which represents the student pilot‘s station of a class of aeroplanes
Note 1 to entry: BITD (3.1.7) may be equipped with screen based instrument panels and spring-loaded flight controls,
providing a training platform for at least the procedural aspects of instrument flight.
3.1.8
computer based training
CBT
training software implemented on personal computer or workstation allowing self-training of aircraft
system knowledge, operation and use
Note 1 to entry: For CBT (3.1.8), no cockpit replica required, the interactive trainee-machine being via the screen, close
to real-time.
