Back in 1976-77, when working for the Plessey Company, we did a lot of
simulation and feasibility work for the British CAA (Civil Aviation
Authority) on a standard for a microwave landing system. The US (FAA,
Bendix and Hazeltine) had proposed a time-reference scanning beam
system (TRSB) whilst CAA took the side of a Doppler scanning system
(proposed by a British company STL); eventually ICAO adopted the US

Does anyone know of the status of MLS? Waiting for the fog to clear
>From London-Heathrow a few weeks ago, the ICAO term
'all-weather-operations', which sadly it wasn't, returned to me. Also,
anyone know of the fate of Hazeltine & Bendix -- I assume swallowed up
in mergers?

Best regards,
