Glossary

FSTDFlight Simulation Training Device

Generic term for simulation-based flight training devices: FFS, FTD, FNPT and BITD. Each FSTD is qualified by the competent authority at a given level.

FFSFull Flight Simulator

Full-size replica of a specific aircraft type or model flight deck, with an out-of-the-flight-deck visual system and a motion system. It is the highest-fidelity category.

Levels A to D (D = most demanding requirements).

FTDFlight Training Device

Replica of an aircraft type's instruments, equipment, panels and controls in an open or enclosed flight deck. A motion or visual system is not required at every level.

Levels defined by the applicable CS-FSTD (for example 1 and 2 for aeroplanes, 1 to 3 for helicopters).

FNPTFlight and Navigation Procedures Trainer

Device representative of an aircraft class or type, mainly used for flight and navigation procedures training, notably instrument flight.

Levels I, II and III, with an MCC variant for multi-crew cooperation.

BITDBasic Instrument Training Device

Basic instrument flight training device representative of a class of aeroplanes. It may use screens to depict instruments.

QualificationFSTD qualification

Assessment by the authority of an FSTD's compliance with CS-FSTD, based on a qualification test guide (QTG). It leads to a qualification certificate and recurrent evaluations.

MaintenanceMaintenance training devices

Simulation tools for technicians (CBT, VR/AR, procedure trainers, mock-ups) are not FSTDs. Their use is assessed within the Part-147 organisation's approved training programme.
