A SURVEY of recent developments in the field of air brakes is presented here. For instance, improved versions of the compressor, brake valve, relay emergency valve, and the hose coupling are described. The rotochamber, which is an improved type of brake chamber is covered, as well as a new, combined quick-release and limiting valve, and also the protection valve, which seals off the straight air and emergency trailer connection on the tractor, should the trailer break away. The author also emphasizes the importance of maintenance in keeping the brake system operating at top efficiency, for he believes that most of the chronic braking troubles being experienced today on heavy-duty vehicles could be eliminated if the brakes were analyzed and then subjected to a well-planned and executed periodic maintenance program.

THE authors have found that of the many factors influencing ground and direct costs, these five have the greatest effect: 1. Payload. 2. Ratio of payload to number of passengers. 3. Number of ground stations. 4. Average length of passenger journey. 5. Administrative policy and efficiency. The effects of these factors on a sample airline are shown in a series of graphs.

A NUMBER of the cost aspects of management are discussed with a view toward improving overall airline efficiency. Utilization of airplanes alone does not greatly affect operating costs. Low costs are the result of high utilization of all equipment and personnel, the author stresses. Lengthening periods between inspection and overhaul-but always satisfying reliability requirements-can bring significant economies, a survey covering timing of various maintenance operations for one fleet shows. Five possible goals of cruise control are discussed, with emphasis on maximum payload miles per dollar. Analysis of the value of weight saving in aircraft results in a formula for finding the annual revenue value of the weight involved.
