I have a canpass for my private aircraft. They want to know where you
land now, or may land, but it doesn't have to be a complete list.
They're more interested in a complete list of possible aircraft, as
they do an owner check on them as well. If you're flying up in a
non-usual plane, your canpass will still work, but you have a higher
chance of a "random check" since the plane hasn't been pre-cleared.

This is what I got when they called me when they got my application (I
left a number off the credit card portion of the app.. ooops..)
