My point was that the certification requirements for CTA in the old manual were adequate, safe and approved - no need to impose greater costs for no justified reason or because someone 'thinks it is a good idea'. I have been legally operating my LSA in Class C D & E for the last 8 years without any problems, as have others. (Transponder certification was always there)
The proposal for CTA for pilot certificates has nothing to do with increased certification requirements of the aircraft instruments - the instruments always needed calibration testing (12 monthly for CTA) just not by a GA licenced business operator.
The risk of conflict in "flying along at 3,500 feet in class G" is far greater with many/some not using area QNH then it is in controlled airspace, but again that is a pilot issue - nothing to do with instrument calibration.
Anyway no point in carrying on here, I just wanted to make my point clear that this is further costs imposed on an area that was working fine already - my frustration at trying to have V4 addressed "before" being submitted to CASA compelled me comment, fully aware that it will achieve nothing constructive.
