Hi all,
@Viper : it is strange, IIRC there is a wedding cake in the TAD when you press TMS up long in the TGP in AA mode with an AC locked.
Having the problem mentioned above by Kingpinda (and no AIM9), I "solved" the problem by hooking the wedding cake in the TAD : there appears a "hook box" (with dotted lines) in the HUD, more or less on the position of the AC locked in the TGP.
Doesn't it mean that the AC is the SPI?
