GB, the 45 degree cone Doug was referring to encompassed both sides of the
extended centerline. Imagine a large X and Y axis superimposed on any airport (with the X-axis aligned with the runway centerline). There are thus four quadrants. If at any time I am moving in respect to the airport in one of those quadrants, I will either be in a "downwind" general direction, a "base" direction, a "final/upwind" direction, and a "crosswind" direction. The "Final/Upwind" direction represents the domain of what consitutes a "final" in my way of thinking (which appears to be shared by at least three ATC controllers). If you approach an airport at 30 degrees off the extended centerline (something that I'm sure most of you have done thousands of times--as I have), what leg are you flying?

Clearly, there is NO OBLIGATION to intercept the centerline at any PARTICULAR point (although it must be intercepted at SOME point to land the plane; which I clearly did in this case--at ~1/2 mile from the numbers). Well if you were approaching with a 30 degrees angle you were in a 60 degrees cone, outside Doug's definition. GB |

Oops, meant to say "the X-axis aligned at a 45 deg angle to the runway
centerline). "Jim Cummiskey" wrote in message news:3xqTc.37453$ih.9766@fed1read07... GB, the 45 degree cone Doug was referring to encompassed both sides of the extended centerline.

Regards, Jim Ok, now you are saying 45 degrees each side of the extended centerline. So if then I call downwind the controller would say something like: " You are number 2, number one is a c172, between 10 and 2 oclock, 7 miles, do you have him in sight?" Well a pretty big slice of sky to look for you. Yes, you said there was no other traffic, but this is not the point. GB |

A 45 degree cone encompassing both sides of the extended centerline would be offset 22.5 degrees from the centerline on each side. Your 30 degree offset put you outside of that. |
