Similar to a procedure turn?

Not only is it similar to a procedure turn, it IS a procedure turn.


This depends on how much you want to play with words.


My intent wasn't to play with words.


Sorry, I didn't say that right, I was just trying to get a handle on how to
address the ambiguity and conflicts in the FAA's terminology.

In real life, I'm just a software
geek. I'm thinking that the "hold in lieu of procedure turn" is a
subclass of "procedure turn", therefore it IS a procedure turn (or
written more conventionally in computer-science-geeky terms, is-a PT).


In one sense, a HIL is certainly a subset of PT, and I think that is true
relative to the P/CG and ICAO definitions of PT. However, if A is "in lieu
of" B, then A and B are different things, and not hierarchically related,
IMO. Otherwise, the FAA could call it a "racetrack-type PT" or "hold-type
PT". These are the terms I try to use in my common usage.

This could be clearer, terminology wise. It is not worth the interminable
confusion it causes.
