A couple of those have interesting tracks.

Yeh, the two humpty-dos In the upper right hand corner of the second photo would have left me queasy.

Cool photos.

I take it that the steep ones are landing paths. I had never realised just how steep they are until seeing those.

Those are very cool!

Now that I've got a good quality tripod, I'm still looking for a mount though, I can't wait to try doing some light trail shots.

That made me curious, because I've flown probably 70-80 times into San Francisco over the last ten years and have never experienced landings that felt that steep.

Perhaps one of our pilots will chime in. I looked up the FAA guidance and found that descents are at a glide path of between 2-10 degrees, with guidance between 3-6 degrees. http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC%20120-108.pdf

If so, there must be some foreshortening effect. Which makes for a cooler photograph anyway.

Standard approach is 3 degrees. This works out to @ 300' per mile descent. Most of the approaches look consistent. Couple landed off centerline by a wide margin.We always shoot for landing in the first 3000', or 1/3 of the runway whichever is less. The glide slope whether electronic or visual (VASI or PAPI) intersects the runway 1000' from the approach end typically.

Certainly hope not.
The steep ones will be the departure flight paths.

Next time you are at an airport watch how steep modern jet aircraft climb compared to the shallow approach.

I flew BWIA into Port of Spain, Trinidad once and I swear the pilot must have been ex-RAF or something. He dropped that 727 like a Spitfire diving for a Stuka, like the light trails in #1. I was thrilled to get off alive. Locals said the initials stood for But Will It Arrive.

Hong Kong looks fun. . .
