SLC Associates are a Company with a comprehensive range of aviation related skills dedicated to aviation support. Our specialists can be called upon to help solve matters from aerodrome development and licensing through to airspace design and instrument approach procedures.

Formed in 1987 to provide a high quality Land and Building Surveying service to the design sectors of the construction industry, SLC Associates now offer a full range of surveying and mapping services. In 1995, the then GPS department completed the first successful British WGS-84 Implementation and Aerodrome Facilities Survey at Jersey Airport.

Since then they have utilised their skills in geodetic surveying to assist more than 95 UK licensed airports comply with ICAO directives on the use of WGS-84 as common datum for air navigation.

Internationally, SLC Associates assists IATA and ICAO with their GNSS Implementation Schemes which, combined with other overseas work, has resulted in successful WGS-84 Airfield Surveys at a further 92 airports overseas including the airports in Anguilla, Bahrain, British Virgin Islands, Cape Verde, Kenya, Kosovo, Mauritius, Montserrat, Nigeria, Oman, Qatar, Seychelles, Turks and Caicos Islands, the UAE and Venezuela.

For the last three years, the specialists at SLC Associates have been working closely with industry partners to devise a method that could be rolled out as an industry wide solution for eTOD (ICAO Annex 15, Chapter 10). The final solution needed to, and does, meet the following criteria:

Does not interfere with the operations of the ATC

Can be utilised anywhere in the world regardless of local hazards or dangers

Combines both the terrain and obstacle survey in one single operation

Capable of meeting the higher accuracy requirements of other ICAO documents (Annex 14, Annex 4, Doc 9674, etc)

Economically acceptable
