There are two aspects to being "on the glide slope". First, are you on _any_ path that ends up at the beginning of the runway? Second, are you on the _intended_ glide slope?
For the first, I was taught to look at the intended landing spot and, being aware of the windscreen, see whether that spot is stationary relative to the windscreen. If so, you are on track toward that spot. Try to see and feel this before worrying about _which_ glide slope you're on. It seems to work quite well. (Or perhaps you've already got this part OK; I wasn't sure from you're description.) For the second aspect, as David (I think) said, I was taught to recognise the "on-screen geometry" of the runway, mainly the angle of its edges. That works well in getting used to your home airfield, and after gaining experience there, you will be comfortable enough to adjust for unknown runways by picking up more than one cue at a time. (I remember thinking "runway looking good ... looking good ... oh, airspeed! quick! ... that's better ... that's better ... oh, where's the runway gone?". Maybe not literally, but that's what it felt like. I stopped flying after getting a PPL, and never really reached the comfortable stage. So please don't trust my tips and advice too much.) - Julian > from: Andy Ross <[EMAIL PROTECTED]> > > David Megginson wrote: > > Andy Ross wrote: > > > Judging glide slope is still difficult, and will remain so until we > > > get some kind of approach slope lighting (VASI/PAPI/FLOLS, whatever) > > > implementation working. > > > > Speaking as someone who has just learned this stuff, I'll assert > > that estimating a glide path and extended centerline is not that > > tricky in good VFR conditions when the runway is level (sloping > > runways cause all kinds of misery). > > Heh, I hear what you're saying, but can't quite *do* it.
