  • Physiological studies on air tanker pilots flying forest fire retardant missions
    Physiological studies on air tanker pilots flying forest fire retardant missions.
    Melton, C.E. ;
    Wicks, Marlene
    1968-10-01 | PDF
    Pre-flight and post-flight studies were carried out on five air tanker pilots; in-flight studies were carried out on four of these five pilots. Pre- and post-flight studies consisted of a questionnaire and determinations of blood pressure, psychomotor performance and urine chemistry for stress metabolites. In-flight studies consisted of ECG, rectal ...
  • Cockpit noise intensity eleven twinengine light aircraft
    Cockpit noise intensity : eleven twin-engine light aircraft.
    Tobias, Jerry V.
    1968-10-01 | PDF
    Eleven of the most popular twin-engine general-aviation light aircraft were tested for the noise intensity present during normal cruising operations at 2000, 6000, and 10000 feet MSL (mean sea level). Although generally quieter than single-engine planes, these aircraft, in comparison with currently accepted DRC (Damage-risk criterion) curves, have ...
  • Assessment of the brocasulzer phenomenon via inter and intramodality matching procedures studies of signallight brightness
    Assessment of the broca-sulzer phenomenon via inter- and intra-modality matching procedures : studies of signal-light brightness.
    Lewis, Mark F. ;
    Mertens, Henry W.
    1968-10-01 | PDF
    Signal lights are presented to an observer as flashes with finite duration; thus, the effect of flash duration on the apparent brightness of the signal is important. The relation of effective signal brightness to flash duration and luminance finds expression in the Broca-Sulzer phenomenon. This study was concerned with the effect of method of measu ...
  • Adaptation to vestibular disorientation X Modification of vestibular nystagmus and vertigo by means of visual stimulation
    Adaptation to vestibular disorientation. X, Modification of vestibular nystagmus and "vertigo" by means of visual stimulation.
    Collins, William E.
    1968-10-01 | PDF
    A conflict among sensory signals frequently underlies problems of disorientation, vertigo, and motion sickness. In this study, visual information in conflict with vestibular signals was presented to groups of subjects by illuminating the test room for brief periods during angular deceleration, or immediately after termination of deceleration. Trial ...
  • A table for converting pH to hydrogen ion concentration H over the range 59
    A table for converting pH to hydrogen ion concentration [H+] over the range 5-9.
    Fiorica, Vincent
    1968-10-01 | PDF
    The wider use, in the future, of hydrogen ion concentration (H+) rather than pH to describe and evaluate acid-base status will require interconversion of the two notations until a final standard is adopted. The relationship between pH and (H+) is given by the general expression pH = - log (H+). Tables relating pH and (H+) have been constructed acco ...
  • Fatal injuries resulting from extreme water impact
    Fatal injuries resulting from extreme water impact.
    Snyder, Richard G. ;
    Snow, Clyde C.
    1968-09-01 | PDF
    Increased overwater flight has resulted in an increase in both military ejections and civil crash landings in water, 78 general aviation water accidents occurring in 1965. The objective of the study was to determine mechanisms of gross trauma in non-penetrating fatal water impact.The method involved analysis of necropsy data on 169 fatal (52 female ...
  • A comparative study of air traffic trainee aptitudetest measures involving Navy Marine Corps and FAA controllers
    A comparative study of air traffic trainee aptitude-test measures involving Navy, Marine Corps and FAA controllers.
    Cobb, Bart B.
    1968-09-01 | PDF
    The study concerns the experimental use of several commercially-published aptitude tests and a determination of their validity as predictors of training-performance grades for more than 300 Marines and over 600 Naval students who entered a basic air-traffic-controller (ATC) training course. The results indicated that a composite score involving onl ...
  • Twoflash thresholds as a function of flash luminance and area
    Two-flash thresholds as a function of flash luminance and area.
    Lewis, Mark F.
    1968-09-01 | PDF
    The recent use of strobe lights in aviation suggests the possibility of using temporal patterns of short duration flashes as information-carrying signals. Under night flight conditions, two-flash thresholds were obtained using a two-interval, temporal forced-choice technique with foveally fixated circular targets varying in luminance and area. For ...
  • Drug and toxic hazards in general aviation
    Drug and toxic hazards in general aviation.
    Dille, J. Robert ;
    Mohler, Stanley R.
    1968-09-01 | PDF
    Drugs and alcohol are frequently cited as major causes of automobile accidents. Druges are rarely reported as a cause of aircraft accidents. This is due to the relatively infrequent search for their presence and to unprecise definition of levels at which most of them begin to impair pilot performance.
  • A comparison of effects of peripheral vision cues on pilot performance during instrument flight in dissimilar aircraft simulators
    A comparison of effects of peripheral vision cues on pilot performance during instrument flight in dissimilar aircraft simulators.
    Hasbrook, A. Howard
    1968-09-01 | PDF
    Pilot response to peripheral vision cues relating to aircraft bank angle was studied during instrument flight in two simulators representing (1) a conventional, medium weight, piston engine airliner, and (2) a heavy, jet engine, sweptwing transport. There was no statistically significant difference found between pilot performance in the dissimilar ...
  • Cockpit noise intensity fifteen singleengine light aircraft
    Cockpit noise intensity : fifteen single-engine light aircraft.
    Tobias, Jerry V.
    1968-09-01 | PDF
    Fifteen of the most popular single-engine general-aviation light aircraft were tested for the noise intensity present during normal cruising operations at 2000, and 10,000 feet MSL (mean sea level). In comparison with currently accepted DRC (damage-risk criterion) curves, the noise levels found even in the quietest plane tested could be damaging. H ...
  • The effects of alcohol at three simulated aircraft cabin conditions
    The effects of alcohol at three simulated aircraft cabin conditions.
    Higgins, E. Arnold ;
    Davis, Audie W.
    1968-09-01 | PDF
    In a study of 54 human subjects using three alcohol consumption levels and three simulated cabin conditions it was found that alcohol caused an increase in heart rate and an increase in skin temperature. Internal body temperature was lower with alcohol but did increase as blood alcohol levels decreased. The performance tests used apparently were no ...
  • The effects of cognitive appraisal of stress on heart rate and task performance
    The effects of cognitive appraisal of stress on heart rate and task performance.
    Thackray, Richard I. ;
    Pearson, David W.
    1968-09-01 | PDF
    In aviation occupations, performance impairment under stress conditions is particularly undesirable. However, individuals may show differing amounts of impairment under stress, and the reasons for these differences are not clear. The present study explored the extent to which individual differences in previously expressed fear of a specific stress ...
  • Effects of two antihistaminecontaining compunds upon performance at three altitudes
    Effects of two antihistamine-containing compunds upon performance at three altitudes.
    Higgins, E. Arnold ;
    Davis, Audie W.
    1968-06-01 | PDF
    In a study of 45 human subjects it was determined that a compound drug containing the antihistamine phenindamine did not statistically impair performance on a modified Mashburn coordinator. Another compound containing the antihistamine chlorpheniramine did impair performance. Performance was also impaired by increasing altitudes. The combined effec ...

    Thirty-six young men were exposed for 2 hours to environmental temperatures of 10, 26.7, or 46C. Measurements of rectal and skin temperature, heart rate and respiratory rate were made, and average skin and average body temperatures were calculated. Manual performance consisted of standardized peg tests for hand and finger dexterity, and a written m ...

    Schroeder, David J.
    1968-05-01 | PDF
    The study examined some effects of stimulus size and distance on the persistence of one type of illusory motion, viz., the spiral aftereffect (SAE). Duration of SAE was investigated with stimuli of 2, 4, 8, 12, and 16 inches in diameter. The distance between the observers and the rotating spirals was varied to produce visual angles between 1 deg. 1 ...
