What are the interpretations out there of Annex 14 Volume II 3.1.63 "Location of a final approach and take off area in relation to a runway or taxiway"?
3.1.63 Where a FATO is located near a runway or taxiway, and where simultaneous operations are planned, the separation distance between the edge of a runway or taxiway and the edge of a FATO shall not be less than the appropriate dimension in Table 3-1.
3.1.64 Recommendation.— A FATO should not be located:
a) near taxiway intersections or holding points where jet engine efflux is likely to cause high turbulence; or
b) near areas where aeroplane vortex wake generation is likely to exist.
