A Precision Measurement Equipment Laboratory (PMEL) is a United States Air Force (USAF) facility in which the calibration and repair of test equipment takes place. This practice is also known as metrology: the science of measurement. Metrology is defined as the science of weights & measures, while a PMEL is the place where technicians perform ...
AFMETCAL (Air Force METrology and CALibration Program Office), located in Heath, Ohio is the primary manager of metrology services for the U.S. Air Force.It retains engineering authority for all calibrations performed in the PMEL labs throughout the Air Force, and oversees the contractor managed and operated Air Force Primary Standards Lab (AFPSL).
At 40,000 ft (12,192 m), the ambient air pressure falls to about 0.2 bar, at which maintaining a minimum partial pressure of oxygen of 0.2 bar requires breathing 100% oxygen using an oxygen mask. Emergency oxygen supply masks in the passenger compartment of airliners do not need to be pressure-demand masks because most flights stay below 40,000 ...
A central air data computer avoided duplication of sensing equipment and could be more sophisticated and accurate. [8] The first air data computer was built by Kollsman Instruments for the B-52 bomber. [9] Bendix started producing a central air data computer in 1956 for use on US Air Force jet fighters. [10]
In flight, the air pressure varies slightly at different positions around the aircraft's exterior, so designers must select the static ports' locations carefully. Wherever they are located, the air pressure that the ports observe will generally be affected by the aircraft's instantaneous angle of attack. [12]
Data from the detection grid is fed into ALDARS, which in turn sends messages to each automated airport station informing it of the proximity of any lightning strikes. Lightning strikes within 5 miles (8.0 km) of the station result in a report of a thunderstorm at the station (TS). Lightning strikes more than 5 miles (8.0 km) but less than 10 ...
