MaxSez: Flyin is not for mental midgets it takes technical knowledge and skill. Put this data too use in your Flight Planning and fly like a pro;
If you’re flying a 90-knot approach speed on a -3 degree glideslope, you’ll need to descend at roughly 450FPM (-VS) to maintain the glide-slope!
How did we come up with that?
There’s 2 pretty easy rule-of-thumb’s to figure that approximate descent rate out;
(1) Divide your ground speed by 2, then add a 0 to the end. So if you take 90 knots / 2, you get 45. Add a zero to the end, and you get 450 FPM (-VS) approximate descent rate for a -3 degree Glide-Slope.
(2) Another way to approximate this; Multiply your ground speed,90 Knots X 5 =450 FPM (-VS) you’ll get an approximate descent rate for a -3 degree Glide-Slope with this one to.
