"Is Wilco's PIC 767 realistic?"
How realistic do you expect it to be for $50???
It does appear to be one of the best, if not
the best, add-ons for FS2000 (with the free patch for FS2002 due out early next year).
It can be (and has been) used by real 767 pilots to prepare for recurrent (big) sim checks, but... However, these guys would be aware of general limitations in this sort of simulation (and probably its specific shortcomings, too, if they had kept in tune with the 767 PIC forum at avsim.com ).
In the package, there are some excellent electronic manuals covering a variety of topics. Some of these are not unlike the manuals found on the real aircraft.
*The FMC and autopilot are undoubtedly the best features, with only small errors, omissions and simplifications here and there. *The pneumatics and electrics need some fine-tuning (but generally good).
*Hydraulics seem to be excellent, although I haven't probed these too deeply
*Instrumentation is generally good. Only a few minor errors/omissions here and there.
Due to FS2000 limitations, the following systems are not fully modelled/unrealistic
*Autobrakes
*ILS systems
*Tiller Steering
Also...
Instrument switching is limited and not so realistic.
Fuel burn is not accurate at lower altitudes.
No Pressurisation controls/displays (only warnings).
The Autoland system needs further development
Although there are several configuration options, these may not necessarily match those of your airline.
Ignore the aerodynamics (Despite Microsoft's claims, they are not "As Real As It Gets"), by any stretch of the imagination.
Be sure to factor into the price of the sim, a new computer. You will need all the bells and whistles to get the frame rate up on any aircraft in FS2000 and FS2002. Ignore the minimum requirements on the FS200x box for computer speed, video ram, etc, if you want to keep your eyesight 8-) Go for the fastest everything. You will find more expensive simulators on the market which may not require you to purchase the latest and greatest computer.
All in all, the sim well worth the money (especially so if you already have FS2000/FS2002 and a good computer)... and would be an excellent introduction to glass cockpits (Hope this doesn't sound like an advertisement).
Regards.
Q.
P.S. Be sure to get the 1.1 patch for PIC (it corrects a number of errors in the original version).
