I've flown into AirVenture many times now and was once told by an AirVenture controller that the 2300' 135kt Fisk arrival pattern is under utilized when traffic is heavy and if you are capable of 135 knots and the lower altitude arrival is saturated it is advantages to controllers to have some aircraft maintain the higher pattern because they are assigned a different runway. I noticed this year in particular there is much written on NOT using the higher pattern unless you are unable to fly 90kts. I have on a couple high volume times arrived over RIPON to find airplanes arriving from all directions at 1800' and having a heck of a time determining an order. Sometimes I find two or three airplanes proceeding down the railroad tracks side-by-side or even find pilots circling over RIPON trying to find a gap in which to re-enter the arrival flow. Seems like a bad place to circle to me. Meanwhile there isn't an airplane in sight on the higher arrival. Instead of adding to the chaos at 1800', I'm always tempted (although won't admit) to climbing to 2300' and enjoying a stress free arrival. Are we lucky enough to have an experienced Airventure controller reading the forums that can comment on the flow of the higher altitude traffic, how runways are assigned, and offer some guidance on whether under rare high volume circumstances it is helpful to have 135kt capable airplanes up at 2300' instead of arriving 5 at a time over fisk at 1800'? Thanks!
