Level A
These have: A full enclosed flightdeck, with all
flight crew stations present, and all systems
simulated
• Flight control force vs position tests, with
tolerances.
• Basic motion and visuals, such as night/dusk, or
a limited field of view.
• Objective flight tests, some with no tolerance
other than "correct trend and magnitude".
• A transport delay of less than 300 milliseconds
Level B
With these, you can do all the training and
checking you need, except for takeoffs and
landings. They are constructed as for level A,
plus the objective tests all have tolerances
applied.
Level C
These are rated for zero flight time for pilots with
1500+ hours in a similar aircraft class. They are
constructed as for Level B, plus:
Level D
These are rated for zero flight time, that is, they
can be used for PPCs or OPCs, but not line
checks (not just because you can’t fit the passen-
gers in!), and are constructed as for Level C, plus:
• Weather Radar is simulated and
co-ordinated with the visuals, TCAS, etc.
• Objective sound and vibration test
