摘要

The Slant Visual Range/Approach Light Contact Height (SVR/ALCH) System reports the slant visual range that can be seen when the pilot is at 100 feet above ground level and the approach light contact height, which is the altitude at which a pilot will see five light bars, as a landing is conducted under Category II conditions. To provide SVR/ALCH information, the system utilizes a 100-foot tower equipped with forward scatter and luminance meters, an illuminance meter, a touchdown transmissometer, and a minicomputer to process the data. The system was installed at the National Aviation Facilities Experimental Center (NAFEC) and data collected during the period from the fall of 1974 through January 1976. The main objective of this program phase (Phase III) was to evaluate the SVR/ALCH system in terms of accuracy of the SVR and ALCH algorithms compared to what a pilot actually sees during an approach. From the limited data obtained to date, there is evidence that the algorithms predict SVR and ALCH values which agree reasonably well with what the pilot sees. (Author)

7. Endothermy of dynastine scarab beetles (Cyclocephala colasi) associated with pollination biology of a thermogenic arum lily (Philodendron solimoesense) : Cyclocephala colasi beetles are facultative endotherms that spend most of their adult lives inside the inflorescences of Philodendron solimoesense, where ambient temperature (Ta) averages about 28°C due to floral thermogenesis. Measurements of respiration within a range of Ta showed that active beetles became spontaneously endothermic at Ta below 28°C but were rarely endothermic above it. There was no evidence of endothermy within the inflorescences, indicating that activities in the floral chamber can occur without the high energy expense of endothermy. Bouts of endothermy occurred at lower Ta in respirometer chambers mainly in the evening, when the insects normally fly from one inflorescence to another, and during the night, when they normally eat and mate within the inflorescence. Patterns of endothermy in individual episodes were studied in non-flying beetles with respirometry and infrared thermal imaging. Heat was generated in the thorax by oscillatory waves of respiration that were coupled with thoracic temperature (Tth) increases. Stationary beetles could regulate Tth at about 33°C independently of Ta between 16 and 29°C. At Ta20°C, this represents a 116-fold increase in metabolic rate over resting, ectothermic values. Endothermy was clearly a requirement for flight, and beetles departing inflorescences warmed to about 30°C before take-off. During flight, Tth was dependent on Ta, decreasing from 37 to 28°C at Ta of 37 to 20°C, respectively. The lowest Ta at which flight could occur was about 20°C. Thermal conductance of stationary, endothermic beetles increased at higher metabolic rates, probably because of increased ventilatory heat loss. [O] . Seymour, R.S., White, C.R., Gibernau, Marc 2009
