This is an accident waiting to happen! The problem is MYEF - GGT Exuma International Airport AFIS 118.0; UNICOM 122.8 frequencies are listed on practically every chart there is; however more or less ALL airlines as well as the [Law Enforcement] Helicopter and practically ALL Jet Operators call Exuma on 122.8 - UNICOM; but everyone else uses (correctly) 118.0. I had a near miss with a Corporate jet; flying out on Runway 30 while they were talking on 122.8; straight in to Runway 12. Listening on 122.8 (ground based scanner); I corrected at least 15 aircraft all day long. Having spoken to some [Airline] Pilots; the answer was that 118.0 is NOT on the Jeppesen Chart. I pointed out that it was (3rd column- 'AFIS') but they said that they don't know what AFIS is. Apparently this is the case with the Briefing/Dispatch services used by the corporate jet operators as well as the Airline dispatchers.I need not point out the looming danger of medium size Jets flying into a relatively busy airport on the wrong frequency while half of the other airplanes are on another frequency. It is a disaster waiting to happen. I consider it life threatening as I had a pretty close encounter with the jet head-on (worst case of course due to minimum visible area). If I could; I would issue an emergency NOTAM for Exuma outlining the frequency for the 'advisory control tower' which is 118.0 and that this is the frequency everybody needs to be on.
Reporter stated that commercial aircraft; particularly air carriers; are using the wrong frequency every day. Reported said that in talking with an airline pilot; the pilot stated; 'We fly on IFR flight plans. We don't know what AFIS is.' Reporter stated that his encounter with a corporate jet on the wrong frequency at MYEF was not a NMAC; but it was very disturbing and something worse will happen if this problem isn't addressed soon.
GA pilot reported that most commercial operators flying to MYEF use the wrong frequency for traffic advisories on UNICOM versus the correct AFIS frequency.
