  • 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 ...
  • 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 ...

    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 ...
  • 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 ...

    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.
