I noticed some of the traffic being tracked on my receiver are flying underground. Intuitively, I knew this could not be. So I Googled and learned. I get why it is happening.
So, is there a chart, a rule of thumb, an algorithm, or some such that I could use to make the adjustment based on the pressure deviation from 29.92?
Blue Sky question. Is there a method where I could input the correction factor so that the data on my dump1090-fa/ page is more accurate?
Thanks for any input.
