Austra, please don't get suckered into bad habits, if it's a visual approach you must be able to see the airport and landing runway, not getting the chance to "lock on" to the M6 or M42 is not an option. Now, I will admit that even when visual there can be environmental elements that can be misleading, and extending the c/l is making good use of the information available.. however,, as for the rest? yes we can all calculate a 3 degree glide based on elevation, but come on, dont cook up a home grown approach using the automatics, in fact, it's not legal. Next thing will be creating PBDs within Stars rather than sequencing and it all goes down hill from here. NSF, I am not saying your advice is technically incorrect, the a/c will happily do this, but what's the point if you want to fly a visual..
