"There would be a possibility of conflict if traffic cruising above the transition altitude were on Regional QNH and aircraft only slightly above it were on the 1013 reference datum. For this reason there is a layer above the transition altitude at which cruising flight should not occur, to ensure satisfactory seperation of at least 500ft."
^^ an extract from the air pilots manual.
And what exactly is the "air pilots manual" please?
Ok I presume this refers to Trevor Thom?
Whilst I have every respect for Thom's work not everything you read in a book is correct! It is surely what is specified in legislation and/or the state AIP which is the definitive guide
Yes im referring to Trevor Thom, and what, are you not agreeing with what is being said? It makes sense to me and theres noting in the AIP or legislation about it, just like the quadrantle rule is optional for VFR, we still do it even though its not "legislation."-well some of us do anyway.
