Irrelevant. Table 4-1-1 in 7110.65 is predicated on MSL altitudes, and
that is what ATC uses.



Yes, but you said ATC used service volumes, which are predicated on AGL
altitudes. Do you understand the difference between AGL and MSL? Do you
have any aviation experience at all?



Route procedure design (read AVN, not ATO) indeed uses service volumne
predicated on the elevation of a VOR or NDB where necessary. Controllers
do not. The context of the thread was ATC procedures for direct routing.



Yes, that's why your statement was wrong. I'm glad you managed to learn
something in this exchange.


Not so. You just can't read with any objectivity.
