MLS — A further development: This statement was made by British Airways in March 1978

At the 66th IATA Technical Committee meeting all members were agreed that there was no early requirement for the operational use of MLS. The majority of members felt that it would be ten years before commercial airlines would be using MLS on a significant scale. Nevertheless, the need for an early decision by ICAO in respect of the MLS Technique to be adopted was strongly supported solely on the basis that the current requirement for MLS at small airports was already leading to a proliferation of non standard systems. No evidence as to the scale of implementation or locations where this was occurring was offered nor was it explained how this would affect international aviation.
