What happens when you land at a strip where there isn't any PAPI?
We always aim for about 300fpm descent..I guess at around 70kts given a headwind that will equate to about a 3deg descent but it isn't a point that is even mentioned until IFR training. Under VFR training it is a meaningless point.
Just a point though what happens when ATC tells you to do a quick and short approach to squeeze you in between traffic?
