this is a bit of a tricky one.
I was reading on the forum that upon approach you should need about -300 vs per nauticle mile.
Now I know this can differ depending on air port/glide slope but I was approaching a consist terrain airport so no need for a steep guide slope in a 737 (simulator obviously) and I noticed ILS was instructing me to be much higher than 11000ft.
I was 3.5 NM out so (300vs x 3.5 nm = 1050ft)
So why was it instructing me to be higher? What’s the actual ratio of VS to NM desired?
-Also I noticed there’s nothing to suggest what speeds percentiles should be activated.
737s usually land between 130 to 145 knots (GS)
With flaps full (40^)
So what speeds for 30^ etc?
Now I know these are tricky questions so no worries if I’m assumed to be pedantic.
Look forward to your response
