Cruise Flight Levels
Good day,
We all know of general quadrantal rule of cruise flight levels (i.e. 180-359 even, 000-179 odd) applicable in most European states. However AIP section 3.2 (ATS routes) may prescribe direction of flight levels (odd or even) which is opposite to the mentioned rule. I.e portion of airway with magnetic track of say 270 is prescribed to be flown on odd flight level. It is clear that we should conform to section 3.2 of AIP when choosing FL's for flight planning purposes, but actually no document (even ICAO docs) say that there may be exception to general "table of cruise flight levels" and that you must refer to AIP for specific FLs on particular airways.
Could anyone point me at a specific doc which says that we must conform to AIP section 3.2 (ATS routes) for FL selection, rather then general table of cruise flight levels.
Thank you.
