If you cross it at 1120, you're 945 feet AGL (referenced to the runway surface). So, to hit the numbers, you need to keep a 590 ft/nm descent gradient from CULVE to the runway. Looking at it another way, at 90 kts and no wind, you need an 885 ft/min descent rate. That's fast, but not outrageously so. It's about twice as steep as an ILS. Maybe easy in a 172 but not in my Mooney. With gear and flaps out and power at idle I don't think I can do 885 ft/min without a lot of slipping. Even if I could there is still the issue of going from 90 knots approach speed down to 70 knots threshold crossing speed. This is why I was 3/4 down the runway. I'm still wondering how the GulfStream did that. I've never flown a Mooney, so I can't speak for what it can or can't do. The charted procedure only promises that if you fly the specified course and altitudes, it'll keep you from hitting any terrain. There's nothing that promises that any particular aircraft has the required performance to land straight-in (or any other way, for that matter) out of any particular approach. Figuring that stuff out is all part of pre-flight planning. What is your point? That the GulfStream shouldn't have been able to touch down on the numbers or should have? You've lost me. -Robert My point is that people should do pre-flight planning and not wait until three quarters of the the runway is behind them to start thinking about whether they can land on what's left. |
