All IAP charts in their respective AIPs need to have the RA HEIGHT published at the 1000' HAT distance point. As an addition to the international standard, respected and observed by the NAA/ANSPs.
Very easy to do, unambiguous and proper solution to what is a narrow but very deep hole lurking there. No need for ADS-B-whatever or CPDLC/S. Pure, old, tested and reliable geometry.
