From: last time I looked I was still here.
Most airliner ground speeds on 3 degrees at F5 = 800 - 900 fpm with a 10kts head wind. Thus if you can achieve >1000fpm you can capture from above. If started early enough it is very possible before 1000' agl. F15 & gear
(B737) or F5 & speed brake will give 1200-1500fpm. No drama and the G/S can be captured before 4nm if you begin the process soon enough. The secret is to realise what is happening, either caused by misjudgement or ATC vectors, and act promptly before the hairs on back of neck get prickly.
