You Gimboid (post #100) -
The parameters you gave, 13 miles at 6000' and 250Kts, is an energy state higher than almost every approach we do in real life. Therefore, IMO, it's not quite realistic and is obviously a completely different scenario then the BA 38 incident.
Every airline I've 'dead sticked' in the sim makes it to the runway from 2000' on G/S at 250 kts. If you're FMC is working you can program that into the box or just do the math in your head (727, DC-9, etc).
The newer jets, being much 'slicker', arrive with more than enough airspeed while 727's just barely made it.
Based on my observations, without very strong winds aloft, I think, almost every jet tracking a glideslope @ 250 KTS has a fairly high chance of success. Next sim session I'll try it from 20 DME and 250kts and figure out how high I have to be to have enough energy to reach the field.
Modern airlines glide at about 18:1. In simple pilots talk that's your altitude in thousands x 3 IE, 30,000 becomes 30 x 3 = 90 n.m.
