Watching the CS100 certification of the 5.5deg steep approach into London City, I wondered if there were any airports with steeper standard approaches. By standard I mean published.

I have seen very steep non-standard approaches, but this is not the point of this question.

    $\begingroup$ When I was living in Miami and had a relative typing flight plans for the FAA there, the airport at Tegucigalpa, Honduras, was notoriously the one where the passengers were most apt to be sharing an experience otherwise familiar only to dive bombers. $\endgroup$

I found the RNAV approach to Steamboat Springs at 7.75°

    $\begingroup$ You win for steepest approach. Note, though, it only allows cat A and B aircraft. $\endgroup$

    $\begingroup$ @TomMcW True enough, so far. The runway is 450ft shorter than London City but it's the weight limit that is the disqualifier. $\endgroup$

    $\begingroup$ Wow that is a steep approach! $\endgroup$ Sep 30, 2018 at 23:42

One of the steepest approaches within the CONUS is the LOC/DME approach to Aspen, CO, which has a final approach segment with a recommended approach glideslope of 6.59°.

I nominate Sion, Switzerland (LSGS).

The IGS for runway 25 is 6°. Here's the vertical profile of the approach plate:

Another, ehem, published approach is the Space Shuttle's MLS runway 33 approach at Kennedy Space Center. 20° when light:

    $\begingroup$ @IanF1: Also "missed approach n/a". :) $\endgroup$ Sep 29, 2018 at 11:05

    $\begingroup$ I think the 20° approach is only for gliders :) $\endgroup$

    $\begingroup$ Kudos for Kennedy originality, but not what I was thinking "standard" meant. I think the 3/95 publication date also slightly violates the FAA 56 day rule.) $\endgroup$

Just came back from a backpacking trip into Lake Placid KLKP, glide slope 7.92, and the relics of the olympic ski jumps looming a 1/2 mile to the S of the runway which are to be avoided on the missed approach....which we were.enter image description here

I'm a bit late to the conversation, but I think I have a winner so far, at 9.61° for the KASE VOR/DME-C approach.
