Why in the world wouldn't you just fly 135 knots at 2300?
Yeah, I don't know why more of the retract crowd doesn't do this.
Several reasons - And I'm saying this as someone who is intimately familiar with the procedure, having done it somewhere in the neighborhood of 40 times now, toured the tower and visited Fisk during the show and talked to a bunch of the controllers, etc...
First reason: Because that's what the NOTAM says. They watered down the language a bit this year so that it says "unable to maintain 90 knots comfortably" but it used to say "Unable" period, and even stronger language in the past. To me, that means twins with a Vyse of greater than 90 knots, and maybe a few other exceptions... But there are other reasons too:
Second reason: Well, this one is aimed at the Cirri, Bonanzas, etc that are going to GAP or GAC. You'll save a couple of minutes of flight time on the arrival, but generally if it's fairly busy, the 90-knot arrival will go to 9/27 and the high arrivals will go to 18/36 - And if that happens, you'll spend up to an extra half hour taxiing, which will WAY more than kill the couple of minutes you saved on the fast arrival. Plus, if you're in a Cirrus, you're greatly elevating your risk of shredding your wheel pants with that long grass taxi. So, want to get in fast? Do the low arrival.
Third reason: If there's a nice stream of 1/2-mile-in-trail traffic on the low arrival and you come flying up the high arrival... Guess who's getting sent back? I guarantee it's not one of the nice stream.
I've done it both ways in the Mooney, but for the above reasons, I greatly prefer the low arrival, and that's the one I'll do as long as everyone's maintaining 90 knots. I do it with the gear down (controllers get antsy if you don't have your gear down by Fisk) and a notch of flaps so that I can keep my nose lower and see preceding traffic better.
So how does one define safely? If I have to fly nose high to keep ninety knots and can't see over the nose, even though the plane isn't "mushy" does that mean it is no longer being flown safely?
If you just leave your attitude behind, you'll have a much lower angle of attack at 90 knots and it won't be a problem any more.
80mph is what I cross the numbers at and is well below safe if clean.
Nobody said you should fly the arrival clean. Like I said above, I fly it with the gear down and a notch of flaps to keep the controllers happy and the traffic visible.
