SID PLATE,
Yes, I saw that xplanefactor was talking about solving an exam question. Your point about exams vs practice is certainly valid.
What we did on the rare occasion when a
rate of descent was needed for a non-precision approach (constant angle non-precision profile from FAF to MDA) was half the ground speed X10. And you could do this in your head. It gets you within +/-50fpm for a
three degree descent path.
There's a reason they're called "non-precision" approaches.
