Good Old Dive-n-Drive
With all the talk of continuous descent non-precision approach techniques and vertical descent angles, you might think there’s no place for dive-n-drive. You’d be wrong.
Everyone seems to be on the “constant descent final approach” (CDFA) bandwagon these days, telling us to avoid the trusted and long-used dive-n-drive technique on non-precision approaches. To be clear, I am not arguing against using a CDFA technique. Indeed, CDFA is a valuable tool. Add the availability of an advisory glideslope from modern navigators—although not required for a CDFA—and CDFA becomes as simple as an ILS. So, why use dive-n-drive at all? I’m glad you asked.
