This fits in with flying through an instrument approach, which is being discussed on another thread. Nothing explicit to prevent you from doing it, but is it really a sensible thing to do? No.. .. .Out of interest, though, does anyone know how to tell how how a glider-launching cable goes? The 1/2-million charts indicate which fields use cables, but I can't see any way of finding out how high I have to be to avoid it - so I usually just try to keep well clear. So you have to detour by a couple of miles - not going to make all that much difference really, is it? . .. .FFF. .-------
