Hi Hector,
That's something that was not possible to implement on the time we developed ProPilot

The divert procedures.
The ProPilot, right now, doesn't have a chance to know if you didn't landed on the correct airport.
The new version, (not the one that will be released until December, but the one for the next year) will have that possibility.
Basically the 2009 Version will check if you landed on a 20nm radius on the center of the destination airport. If not it will ask you if you diverted to other airport. And if so, the airplane will be become inactive for 2 days until it get's back to the final original destination.
Don't worry. Continue flying
