I have found some games on the Eurocontrol website. Playing these games can help you preparing yourself (a bit) on phase 1 of the Feast test. They're also fun to play....
Taken from the Eurocontrol website:
"EUROCONTROL has created a number of open e-learning courses which are available to the public without registration.
This courses intend to inform quickly in detail a great or a world wide scattered audience on air traffic management subjects of public interest (such as safety, standards, environment etc)."
