vc10man - Notice the first post said I was flying to DTW, Detroit Metro.
BeachPilot - If I am below the glideslope I should intercept it as I approach the runway. Thus as I said, it works OK if I maintain a higher altitude. My question is not how to fly a glideslope, but what config files define it. Is it defined in the AFCAD file? And if so how can I tweak it?
