So this thread has been helpful, maybe I can get another rule of thumb answered. The mighty Talon typically does a 5 degree descent profile which makes starting down calculations easy -- just double the altitude to lose + 5-10 nm slop to slow below 300 before we get <10k and we're good.

I've been studying a lot of techniques from interview gouge and it seems the most common descent gradient rule of thumb is multiply the altitude to lose by 3, which gives a 3.33 degree descent gradient. Is that a pretty standard airliner descent profile?

Thanks!
