What are these suffixes used after the call sign? I often play a flight simulator game Infinite Flight (http://www.infinite-flight.com) on my iPhone. The game lets you choose the following suffixes with your call sign.


Heavy
Super
Flight of 2
Flight of 4
Flight of 5
Flight of 6
Flight of 7
Flight of 8
Flight of 9
Flight of 10


I am aware what "Heavy" means but now aware about the rest. Can someone let me know?

Thanks
Heavy - all aircraft with maximum take-off weight greater than 300,000lbs (whether or not they're operating at that weight) It's to highlight to the controller that wake turbulence could be a problem for a following aircraft.

Super - Airbus A380: As for 'Heavy', but more so.

Flight of X - All the rest relate to groups or formations containing that number of aircraft.

These originate in the FAA regulations and are summarised on Wikipedia

There are a number of other unusual suffixes including 'Concorde' (used only by British Airways for the now retired Concorde), Lifeguard (for medical flights), and others
