Inspired by this answer, and the comments that followed.
City politics aside, i.e. hypothetically, can KBOS rwy 14 be used for landing aircraft that don't comfortably need more than 5,000 feet of runway?
The issue arises from the building at the approach end of rwy 14.
The building is 174 ft. tall, lighted, 1364 ft. from runway, and 70 ft. left of center line.
The RPZ (protected zone for excursions) by FAA standards is 1000 ft., which the runway meets.
FAA also says the OFZ (Obstacle Free Zone, the 3D area covering the approach end) would only be 200 ft. since there is no Approach Lighting System installed.
In summary, imagine the building is a rocky outcrop somewhere in a desert, and someone built a 5000-foot runway the same distance from it as KBOS 14, can it be legally used?
Visually I don't see why not, but I'm not an FAA administrator. And for an instrument approach I also don't see a problem stepping down to a specified MDA, and even at an angle (LDA).
To raise the stakes a bit, I believe a DC-9 can comfortably land on a 5000-foot runway. Let's use a DC-9 or similar type in the example above.
To make the answer less stressful, if you know of a similar airport/obstacle scenario, or can find one, with a published approach, let us know.
