RUNWAY-THRESHOLD SURVEY ???
Chapter 5 point 5.3.1.2 of ICAO Doc 9674 provides that the survey is to be made at the beginning of the PAVED SURFACE
Can whe conclude that UNPAVED RUNWAY are excluded from the in chapter 5 point 5.3.1.2 of ICAO Annexe 15 requirement.
So far I understand this is now the case for the GRASS RUNWAY
What is the ICAO Definition of a PAVVED SURFACE in Anexxe 14 or ICAO Doc 9137 part III ???
Somme REGULATORS are intending to have all the for VFR used GRASS AERODROMES AUTHORITIES to have such a costly THRs of GRASS RUNWAY to be surveyed, witch according me is a unneeded and costly aplication for the VFR operations
I ame intrested in YOUR ADVISE or COMMENTS on this proposal ASAP ??
