According to the requirements of Annex 15 para 1.2.1, we need to implement WSG84.
There might be a lack of my understanding regarding the proper actions on this issue.
CAA Bangladesh has published all aeronautical geographical coordinates (indicating latitude and longitude) in terms of the WGS-84 geodetic reference datum for all types of critical points including Waypoints, RWY THR, NAV AIDS, obstacles, etc. Which have been published in our AIP also, available in CAAB website.
But ICAO put the deficiency for WGS84 not implemented.
So would you please explain what actions we should take actually on this issue of WGS84.
