Unless it says 1000, I believe it covers from the viper powered basic or 1a to 800xp. There are something like 30 plus varients in the HS line. Basic ac, get it started and it will get you home. The biggest drag is the takeoff charts where you will learn the value of "D". Spend the coin, buy an Ultranav program for your computations. Or, learn to spend time in chart performance madness. You will see. Good luck.
