    Through the years the art of aircraft control has progressed from the use of fundamental human observations that restricted operations to contact conditions, to modern flight instrumentation that permits the precise control of modern high speed, high performance aircraft under very restricted ceiling and visibility weather conditions. The story of improved flight instrumentation in this paper includes the evolutionary trend toward more stringent control requirements which has pointed up the limitations of pure human response and resulted in a philosophy that a system capable of greater accuracy must, in addition to providing a fine degree of instrumentation, take human characteristics into consideration. Through a discussion of the symbolic and pictorial approaches to providing the ideal flight instrumentation, the present trend toward combining the two approaches is explained and the features of a production system incorporating these modern concepts is described.

    It has long been realized that manual voice-radio and wire telephone communication facilities cannot meet the future requirements of aviation for air traffic control communication services. The operational requirements for an Air Traffic Control Signaling System (ATCSS) are discussed; the relative applicability of a number of existing and proposed communication systems are shown using an arbitrary but consistent rating method. Block diagrams are presented which cover the laboratory experimental equipment of the Melpar Visual Communication System (VCS). A typical sequence of events and their durations for ATCSS service is given. The main conclusion is that a direct viewed bright storage tube display method should be employed in the ATCSS airborne unit, rather than an electromechanical (or ``roller-wheel'') type of indicator system.

    The major advantages and disadvantages of adding the ninth harmonic to the fundamental bearing signal of the TACAN system are presented. The effects of this addition are discussed in terms of the improved system accuracy, particularly under conditions of adverse siting. TACAN azimuth error data that were collected in ready-to-use form by recently developed methods are presented. These data, which allow separation of the site error from the total system error, indicate the azimuth accuracy of the TACAN equipment. View full abstract»

  • Pencil and Paper Calculation of Noise Level in Superheterodyne Radar Receivers

    One method1 for determination of noise level in radar receivers involves the use of a calibrated signal generator for input voltage and use of a quadratic detector instead of the second detector of the radar receiver. By a related method, which is described in this paper, the rms noise level may be determined from the second detector output as a function of receiver input for any common type of second detector even though its response is not exactly quadratic. This method is justified mathematically, and in a practical application the noise level of a 600-mc receiver is determined as 11.2 microvolts (referred to input). View full abstract»

  • Automatic Testing Is Good Business

    Automatic testing can be economically applied in the military electronic equipment business even though it is characterized by small production quantities, complexity of product, and rapid evolution of design changes. It has been the experience of the Light Military Electronic Equipment Department (LMEED) of General Electric that it is possible to determine an automatic test program of long range significance and still see immediate benefits, if the program is tailored to a sound understanding of the needs of the particular business involved. This article discusses the approach to automatic testing at LMEED, some of the equipment concepts involved, and the plans to further the program toward the goal of full automation of the test operation.
