Air Transport Assn.—Sam Saint, director of ATA’s Air Navigation and Traffic Control div., told the American Society of Mechanical Engineers that airline safety would be improved by use of: Lighted distance markers, consisting of signs with numbers large enough to read placed every 500 ft. along runways; better altimeters—designed to read like odometers, inherently self-checking, and equipped with a limit warning-switch that could be set by a pilot to attract attention if the flight path goes below a safe altitude for the area involved; angle of attack indicators with a signal to call attention to stalling danger on landing approaches.
