The prices for the aircraft vary not only because of the differing amounts of specialized expertise that went into creating each bank, but also because the size and scope of the banks varies as well. Some are fairly comprehensive systems reviews, while others are more quick limitations and key systems memorization aids. To make sure that you're happy, the best thing to do is to download the demo version of AirCards for the aircraft you are interested in and try it. Remember, each demo version has about 5% of the total number of questions enabled. Registering / Unlocking / Buying (they all mean the same thing) unlocks the remaining 95% of the questions.

When you purchase AirCards, unless otherwise authorized by us, you are purchasing a single-user, nontransferable license to the software. We offer free lifetime updates AND we let you install this on more than one machine (for example, your desktop and your laptop) as long as you promise that it is for your own PERSONAL study and use only. In exchange for these generous terms, we ask that you hold up your end of the bargain by directing your friends and colleagues to purchase their OWN copy of AirCards. We hope you can find this to be fair.
