Message-ID: <3393@alice.UUCP> Date: Fri, 15-Feb-85 11:07:34 EST Article-I.D.: alice.3393 Posted: Fri Feb 15 11:07:34 1985 Date-Received: Sat, 16-Feb-85 06:26:21 EST Organization: Bell Labs, Murray Hill Lines: 35 While I'm no expert, here's my two cents worth: I was taught to fly nice, squared-off approaches (i.e., downwind leg extended about 1/2 mi past the end of the runway, then a 90-degree turn to base, then a 90-degree turn to final) with partial flaps applied as soon as I reduce power (approx. opposite the end of the runway), and full flaps applied on base, with about 1500 rpm carried throughout (for a PA-28-140, PA-28-160, AA-5A, ...). This technique has the advantage of producing pretty-looking patterns in the sky, (not such a bad thing, since others can guess where I'm going) and a good amount of time to "stabilize" the approach -- nothing happens too quickly, the rate of descent isn't too great, and the technique carries over fairly well to instrument training: the descent angle is pretty much like an ILS approach, but with the two right angle turns thrown in. I fly like this with nervous passengers and FAA inspectors on board. I don't like it, though. I don't like being strung way out on final at about 500' AGL with all that flap hanging out, just waiting for the engine to cough or for someone flying a tighter pattern to cut me off without looking. I would feel real bad flying all the way from point A to point B, always (well, almost always) having a field in mind for a soft landing should the engine quit, and then having to land in the trees with my destination airport in sight. As long as there's no one in the pattern ahead of me (I don't want to cut anyone else off, either), I like to fly a power-off approach, which means about a 180-degree turn from downwind to final. Since I also like to land as slow as possible to save on tires, which means using full flaps, this means flying a pretty steep descent, which means having to flare rather assertively. It means having to use a different technique when I'm under the hood, or flying with my wife, but it also clears me out of the pattern fast and gives me a little more peace of mind. -- Jan Wolitzky, AT&T Bell Laboratories, Murray Hill, NJ; (201) 582-2998
