Capt Wally,
Not many jets at your average ALA but there are a great deal of kingairs etc.
Its the gravel runways that get used by the training orgs for navexs that cause most of the concern. Not to many VFR guys seem to keep the transponder on past the edge of radar coverage and when they overfly they are taught that they are clear of their circuit.
On another point trying to keep a cat B turbo prop within the circling area and not decsending on down wind can be a challenge for a new pilot.
Seems some one wrote a rule from a very low knowledge base.
