Flight system for rating

[CN@ndo]

friends,

I wonder if you can, make a simple flight. example:

A pilot with an initial rating, can operate for 6 airports to complete your scale flight.

The pilot rating and an average amount of time is released routes to 12 airports to complete your scale flight.

When you get to the last rating will be released all domestic and international flights, is it possible?

the idea is good?

tks.
