Joki (OH6DJ)): > From: s32822l@kaira.hut.fi (Ari J. Joki (OH6DJ)) "IFF" is an old term. It's interchangeable with SIF (Selective Identification Feature). A more accurate term today would be "Identification of Some Friends". I don't believe any current "Foe" carry an IFF/SIF system - nor would they be 'squawking' any if they had. All commercial aircraft, I believe, do have an IFF/SIF system. Friendly Military Aircraft have their own - but may not want to 'squawk' during 'hostilities'. So, since 'bad guys' don't, and good guys won't, and commercial may or may not - hence it really becomes "Identification of Some Friends". mms
