Definition
A ground-based training device that replicates aircraft systems, instruments, and flight characteristics for pilot training, checking, and currency. A Flight Simulation Training Device (FSTD) is the FAA's umbrella category covering both Full Flight Simulators (FFS) and Flight Training Devices (FTD), each qualified to specific levels under FAA standards. Unlike a basic procedures trainer, an FSTD is formally evaluated and approved, allowing certain training events to count toward certificate, rating, or recurrent requirements.
Plain English
A ground-based machine that mimics flying a real aircraft well enough that the FAA accepts time spent in it as official training. It includes both full-motion simulators and fixed cockpit trainers, depending on how realistic and capable the device is.
Context Anchor
Seen in pilot training records, flight school scheduling, simulator approvals, and rules about what training time may be credited.
Derivation
“Simulation” comes from a Latin word meaning “to imitate” or “to make like.” That helps here because the device does not have to be the aircraft itself; it must imitate enough of the aircraft and flying situation to be useful and approved for training.
Why Pilots Care
Allows repeatable practice of normal and emergency procedures in a risk-free setting, helping pilots build skills and meet regulatory requirements.
Grounding Statement
A pilot can sit in the device, use aircraft-like controls, see aircraft-like responses, and practice procedures before doing them in the real aircraft.
Intuition Check
Do not read “simulation” as “just a video game.” In aviation, a Flight Simulation Training Device is a specific training device that must meet standards before its use can count for required training or checking.
Example Sentence 1
The airline's recurrent training was completed in a Level D Flight Simulation Training Device, which allowed the entire checkride to be conducted on the ground.
Example Sentence 2
Many hours logged in a Flight Simulation Training Device count toward the instrument rating requirements.
