Ben, the simulator maintained by most flight schools in the US are only
usable for part of the Instrument course, and NONE of the commercial time
building requirements. (ATC-xxx type or Frasca 142 and variants)

If approved by the local FSDO, even Level 1 Flight Training Devices (i.e.
Frasca 142 or AST 300) can be used both for partial time towards the
commercial rating and for either solo instrument currency or an instrument
proficiency check with a CFII. See this link:


I have flown "full motion" simulators in the military, but they did not
count (as far as the military were concerned) for qualification check

or to maintain currency, that still had to be completed in a "real world"

That may be true in the military but is not true of Level 1-6 Flight
Training Devices -- see the link above.

That sound interesting. What requirements does the sim have to be able to

type ratings on it?

Level D simulator which basically becomes so real even the weather depiction
landing in low IFR conditions is realistic --- this is a multi-million $

You don't have to go quite that far. Level C will do fine. Their
visuals are plenty good. They just don't do daylight visuals or have
quite the level of fidelity that Level D simulators have. A night ILS
to minimums in a Level C simulator looks very much like what I've seen
when doing it for real. The landing lights illuminating the pavement,
and the haze for that matter, look very real.

When I talk about fidelity, I'm talking essentially about realism. A
Level C simulator taxiing pretty much glides along as smooth as silk.
The Level D simulator simulates the bumps in the taxiway. In a Level D
simulator, the sounds you hear are very close to the real thing (e.g. my
previous example of dragging a wing on landing). In the Level C
simulator I fly every year, it's very difficult to distinguish between
the sounds caused by a bird strike, an engine failing catastrophically,
and many other things because they're all created by the instructor
smacking the wall of the simulator with his hand.

That is almost correct... in order to use a Level C sim for a type rating
instead of a Level D sim the pilot needs to meet certain prerequisite
experience requirements -- See Appendix 1 Task vs. Simulation Device Credit
at the end of the ATP/Type Rating Practical Test Standards in this link:


For those who are interested, the following link gives an extremely detailed
listing of the technical requirements for Level A through D simulators...
among other items a Level D can do which a Level C cannot do are accurate
representations of mach effect at altitude, weather radar correlated with
visuals, airframe icing scenarios, control bufetting in certain situations,
and flight near thunderstorms:
