  • Pilot heart rate during inflight simulated instrument approaches in a general aviation aircraft
    Pilot heart rate during in-flight simulated instrument approaches in a general aviation aircraft.
    Hasbrook, A. Howard ;
    Rasmussen, Paul G.
    1970-04-01 | PDF
    Eight instrument rated pilots with flying experience ranging from 600 to 12,271 hours each flew 10 simulated ILS instrument approaches in a single engine, general aviation aircraft equipped with a primary flight display arranged in conventional 'T' configuration. Continuous heart rate data were recorded during each approach. Approaches were flown c ...

    Blood alcohol concentrations as affected by combinations of alcoholic beverage dosages and altitudes.
    Higgins, E. Arnold ;
    Vaughan, John A.
    1970-04-01 | PDF
    This study established blood alcohol levels in man at 12,000 ft. with and without supplemental oxygen and at 20,000 ft. with supplemental oxygen. At 2.50ml. of 100 proof bourbon/kg. body weight, subjects exhibited a lower blood alcohol level at 12,000 ft. without supplemental oxygen than at 20,000 ft. with supplemental oxygen. A difference in blood ...
  • Effects of an organophosphorus pesticide on reproduction in the rat
    Effects of an organophosphorus pesticide on reproduction in the rat.
    Ryan, Leonard C. ;
    Endecott, Boyd R.
    1970-01-01 | PDF
    The toxic effects of organophosphorus insecticides are commonly ascribed to cholinesterase (CHE) inhibition. A search of the scientific literature revealed the well-established fact that a number of chlorinated pesticides adversely affect reproduction in mice and rats.However, little is known about the effects of organophosphorus pesticides on repr ...

    Studies on the storage stability of human blood cholinesterases : I.
    Crane, Charles R. ;
    Sanders, Donald C.
    1970-01-01 | PDF
    Whole blood, red cell, and plasma preparations were stored at room temperature, refrigerated, and frozen. Samples were assayed over a 50-day period using the technique of constant-pH titration (pH-Stat). At least 90% of the cholinesterase activity in the whole blood and plasma preparations was retained for 6 days at room temperature and over 6 week ...
  • Tolerances to thermal extremes in aerospace activities
    Tolerances to thermal extremes in aerospace activities.
    Iampietro, P.F.
    1970-01-01 | PDF
    Tolerance for all hot environments cannot be defined by a single criterion. At least three types of tolerance are discussed which might occur in aerospace activities. The tolerance categories have been designated (1) pain limited, (2) heat storage limited and (3) systems limited. Pain limited exposures are of short duration and require very high te ...
  • Quantitative evaluation of optically induced disorientation
    Quantitative evaluation of optically induced disorientation.
    Brecher, M. Herbert ;
    Brecher, Gerhard A.
    1970-01-01 | PDF
    The purpose of this study was to establish quantitatively and systematically the association between the speed of movement of an optical environment and the extent of disorientation experienced by an individual viewing this environment. The degree of disorientation was determined by measuring the angle by which an individual deviates from a straigh ...
  • Fidelity of simulation and transfer of training a review of the problem
    Fidelity of simulation and transfer of training : a review of the problem.
    Gerathewohl, Siegfried J.
    1969-12-01 | PDF
    The document is concerned with the several kinds of flight simulators available today which are valuable tools for research, training and proficiency determination. They range from simple trainer type devices, which are useful for the learning of specific tasks, to very sophisticated ground-based facilities and aircraft used for crew training under ...
  • Determination of centers of gravity of infants
    Determination of centers of gravity of infants.
    Swearingen, J.J. ;
    Badgley, J.M.
    1969-11-01 | PDF
    Recent efforts to provide effective restraint equipment for crash protection of infants in our transportation complex and to develop satisfactory flotation equipment for the little ones have revealed that there is a lack of data concerning the location of the c.g. (center of gravity) of this age group. This study was undertaken to fill this gap. Va ...
  • Motor effects from visually induced disorientation in man
    Motor effects from visually induced disorientation in man.
    Brecher, M. Herbert ;
    Brecher, Gerhard, A.
    1969-11-01 | PDF
    The problem of disorientation in a moving optical environment was examined. Egocentric disorientation can be experienced by a pilot if the entire visual environment moves relative to his body without a clue of the objective position of the airplane in respect to the ground. A simple method of measuring disorientation was devised. In this method cha ...
  • The safety significance of aircraft accident post mortem findings
    The safety significance of aircraft accident post mortem findings.
    Siegel, P.V. ;
    Mohler, S.R.
    1969-10-01 | PDF
    A review of post mortem examinations obtained in 1968 of pilot victims of general aviation aircraft accidents reveals that 51 percent of the pilot victims were studied by pathologists. The post mortem examination population above was taken from 687 pilot fatalities in general aviation accidents occurring within the United States in 1968. The percen ...
  • Adaptation to vestibular disorientation XI The influence of specific and nonspecific gravireceptors on nystagmic responses to angular acceleration
    Adaptation to vestibular disorientation. XI, The influence of specific and nonspecific gravi-receptors on nystagmic responses to angular acceleration.
    Collins, William E. ;
    Updegraff, Billy P.
    1969-10-01 | PDF
    Data from several recent experiments indicate that the otoliths (detectors of linear acceleration) may exert regulatory effects on responses of the semicircular canals (detectors of angular acceleration). This study was designed to explore further this notion.Horizontal ocular nystagmus from restrained birds was habituated in a directionally specif ...
  • A comparison of the behavioral effects of various levels of chronic disulfoton poisoning
    A comparison of the behavioral effects of various levels of chronic disulfoton poisoning.
    Pearson, David W. ;
    Clark, George
    1969-10-01 | PDF
    Exposure of general aviation pilots to toxic pesticides has been reported as a possible cause of impairment of flying performance; in some instances it may have produced fatal results. Of particular concern and interest are the organophophates that are known to be AChE (acetylcholinesterase) inhibitors. It has been generally assumed that inhibition ...
  • Recovery of motor performance following startle
    Recovery of motor performance following startle.
    Thackray, Richard I. ;
    Touchstone, R. Mark
    1969-10-01 | PDF
    Sudden, high-intensity sounds, such as those produced by sonic booms, can be quite startling. Although many studies have investigated physiological response to startle, much less is known concerning the effects of startle on performance. The present study was designed to provide further information concerning the extent to which startle disrupts pe ...

    The spiral aftereffect. II, Some influences of visual angle and retinal speed on the duration and intensity of illusory motion.
    Williams, Mary Jane ;
    Collins, William E.
    1969-08-01 | PDF
    Visual illusions have been a persistent problem in aviation research. The spiral aftereffect (SAE) is an example of one type of visual illusion--that which occurs following the cessation of real motion. Duration and intensity of the SAE was evaluated under five conditions. Results indicate that perceived (rather than physical) characteristics of th ...

    Hoffman, Marlene
    1969-07-01 | PDF
    Eleven male subjects were given flight training according to a conventional but rigidly standardized private pilot syllabus. On half of the dual flights chloridazepoxide was given; identical-appearing placebo capsules were given on the remaining dual flights. No treatment was given on solo flights. Differences could not be distinguished between tra ...
