This has to be the best add-on I have bought. It was worth it for the panel alone. 95% of the aircrafts systems have been replicated and certified by real Concorde flight crew including the flight dynamics. The flight dynamics are that real, that the aircraft even produces the yaw on application of full power as engine No 4 holds at 60% N1 for a few seconds.
Concorde didn't have an FMC. It navigated by using INS. The package out of the box dosn't contain any INS but does make provisions for the brilliant CIVA INS gauge which is identical to the INS system used on Concorde. It even has to be programmed the same way.
There is a very comprehensive manual to accompany it along with real flight plans, checklist's charts and performance charts.
It is a very hard aircraft to learn to fly but worth it in the end. The support of their website is second to none aswell.
