hello,

currently i'm working on a presentation for school together with NACO, a company that has designed more than 500 airports all over the world...even the famous one at St. Maarten.

i'm working on the Polderbaan, Schiphol's fifth runway. this is a CatIII runway.

now i'd like to know if anyone can explain what this means: CatIII? it has something to do with navigation stuff such as ILS but i'd like to know it exactly.

info that has anything to do with runway lights is also welcome.

thanks!!! Wink

Hiya Ken!
I found a few things of interest. Hope it helps out! Grin

The final stage in a three-year project to bring the best in all-weather landing equipment to Bristol International has been completed. On Friday 16 November ‘CATIII’ became operational, enabling suitably equipped aircraft to land safely in difficult weather conditions.

It is anticipated that 80% of passengers could benefit from the system, which will significantly reduce delays related to poor weather at the airport. Bristol International is the only airport in the South West and Wales to have such high-level landing equipment installed.

“CATIII provides the best facilities possible for aircraft using the airport,” explained commercial director Mike Luddy. “It confirms our commitment to offering the highest quality service and safety to our airline partners and their passengers.”

The new system underwent 8,000 hours of fault-free testing before going live. Consisting of a ‘localiser’ aerial, situated at the western end of the runway, a ‘glide path’ aerial, and distance measuring equipment, CATIII gives guidance information to aircraft, enabling pilots to land in poor visibility.

CAT Clear Air Turbulence or Category
CATI Category I Instrument Landing System (uses MALSR)
CATII Category II Instrument Landing System (uses ALSF-2)
CATIII Category III Instrument Landing System (uses ALSF-2)

CAT I- DH(decision height) 200 feet or greater

CAT II-DH 100 feet (using a "coupled"(autopilot assisted) approach to DH and then flying manually to the ground).

CAT III- no DH, the Autopilot takes it all the way to Terra Firma! Shocked

There are other equipment requirements and the crew must be trained for the approach but the above listed numbers are the most distinct differences. Look in a FAR/AIM or check out the FAA website if you need a black&white reference.

.....so I loaded up the plane and moved to Middle-EEEE..........OIL..that is......

Bristol airports biggest waste of money. Because of various reasons, the CatIII system has actually been very rarely used, and the airport has been closed down for fog on numerous occasions. Roll Eyes

Too bad - gotta get the boys from Down East International to teach 'em how to land in fog! Grin
