DESCRIPTION |
| This is a no reserve, SEVEN-DAY AUCTION for a very nice NASA EMBROIDERED PATCH NASA KENNEDY SPACE CENTER RUNWAY LIGHTING CREW PATCH: 10 cm (H) X 10 cm (W). New, still sealed in its poly bag.
An array of visual aids as well as sophisticated guidance equipment at the Shuttle Landing Facility help to guide the orbiter to a safe landing.
The initial landing approach at a glide slope of 19 degrees is more than six times steeper than the 3-degree slope of a typical commercial jet airliner as it approaches landing. The Precision Approach Path Indicator (PAPI) lights are an electronic visual system that shows pilots if they are on the correct outer glide slope. PAPI lights are used at airports all over the world, but these have been modified for the unique configuration of the orbiter. A set of PAPI lights are at 7,500 feet and at 6,500 feet to delineate an outer glide slope of between 17 and 19 degrees. White lights are seen by the crew if the vehicle is above the glide slope; red lights show if they are below the glide slope. If they are "on" the correct glide slope, both red and white lights can be seen.
The "Ball-Bar" light system is a visual reference to provide inner glide slope information. The bar lights are 24 red lamps in horizontal sets of four each. They are about 2,200 feet from the runway threshold, and 300 feet from the first nominal touchdown point. Five-hundred feet closer to the runway threshold are three white lights - the ball - at a higher elevation.
For night landings, the SLF has 16 powerful xenon lights, each of which produces up to one billion candlepower. Flatbed trailers hold eight lights, in two groups of four, at each end of the runway. To avoid blinding the crew, only the xenon lights at the end of the runway which will be behind the orbiter at landing are turned on.
