This article presents the texts of several papers presented at a conference on the relative benefits of carrying navigational devices in an aircraft as against having them (particularly fog-dispersed devices) on the ground and the need to strike a cost-affective balance between the two. A transcript of the discussion following the presentation of the papers is included. "Airborne Equipment for All Weather Operations", by D.V. Warren, Discusses the varying criteria for Runway Visual Range (RVR), Decision Height, and ground guidance system and automatic landing system sophistication under Categories I, II and III conditions. "The Turboclair Process", by M. Bernard, describes a thermo-kinetic fog-dispersal process, in use at Orly and Charles de Gaulle airports, whereby the suspended water droplets are vaporized when hot gas from old turbojet engines buried in the ground raises the ambient temperature. "All Weather Operations by Fail-Operational Autoland", by I.L. McGrath, is a short summary of the history of the development of airborne equipment suitable for use in Category III environments.
