particularly useful when troubleshooting a performance problem (see Section
11.1.2). They can also be recorded in one of the DAS channels (Section 7) for

Absolute, atmospheric pressure is 29.92 in-Hg-A at sea level. It decreases
about 1 in-Hg per 300 m gain in altitude. A variety of factors such as air
conditioning and passing storms can cause changes in the absolute
atmospheric pressure.
