I can recall standing at SFO and watching the transpacific flights barely make it over the hills northwest of the airport.
I was just thinking about the same thing. I'm pretty sure the one I saw 110nm out (near Point Arena California) had departed off 28 Left or Right and out through that slot. Not all departure procedures have to consider obstacles that far out.
The strange one however, is departing the opposite direction, on the 1-0s. Most runways at SFO
, being cool and at sea level, do not have much in the way of restrictions. In the rare event of a departure off runways 10 Left or Right there is something of an anomaly.
On 10R (I think I've got the L/R correct) there is no particular problem - weight limits are driven by structural up to maybe 70 degrees or so, then maybe by second-segment. Of the right, there is a pretty big hit. (on the analysis from some vendors) We've studied this at length and think it is based on Mount Lick. Basically, if you took off on that runway, lost an engine, climbed on runway heading with no wind drift, for 29 nautical miles and did not climb above 4200 feet you would hit a single protruding peak in the Diablo Range.
Well, in my opinion, if you took off, lost an engine, flew 29 miles in a straight line - in defiance of your departure clearance - and did not climb above 4200 feet you deserve to crash into a mountain.
A turn short of, say, 25 miles would save you. A turn of one degree right after flap retraction would save you. But there you are - a smoking hole right below the observatory!
Happiness is not seeing another trite Ste. Maarten photo all week long.
