Trying to liven up the group (is that a word?)
We've all seen it..."procedure not authorized for arrivals via V123 southwestbound", for example on some rnav(gps) approaches. I think this is because terps does not normally allow a turn greater than 120 degrees when a feeder route leads to an IAF. Guru's please correct me.
However, is there anything that restricts a pilot from requesting, or an atc from clearing, a flight to an iaf where the turn at the iaf requires more than 120 degrees of turn?
If yes, then why? Especially cat A that can fly so slow to allow this turn easily I'd think, and remain withing 4 miles of the centreline even with wind considerations.
If no, why does terps have this restriction, but still allow atc to permit, or pilots to perform, the maneouvre?
