The only difference between friend and foe is the wingspan on the airplane in the program. In all other respects the two aircraft are the same. To start with the diffrerence is quite obvious and in later rounds there is hardly any diff so good luck!
With respect to the radar vectors, one instruction is displayed at a time and stays on the screen until you click ok, then a new instruction will come up, the instructions are not spoken.
Suitcase man is alot more simple than the other tests you have sat. There is no sound, there is only one bloke, and all you need to do is select left or right depending on which hand the suitcase is in.
Hope this helps good luck
