A great help and site is simple to navigate. Has virtually no fixed wing topics to distract you. There are a couple revisions that need to be made to keep this up to date, but other than that it is easy and simple to use. This is my 3rd time using the King Schools FIRC for helicopters. You also get a discount if you are a member of VAI (formerly HAI)!
