Is it normal to start descending on the G/S before you have captured the LOC?
Not sure anyone has really asked the question: "descend from (or through) what level?"
On a procedural ILS approach there is a minimum altitude at which the final approach segment begins. On a radar vectored ILS, there is a level to which ATC has instructed you to descend for the intercept. Obviously, one must not descend below those levels prior to LOC intercept.
But is there an issue with using the GS for guidance on the way down
to that level, facilitating a more or less continuous descent?
