Not as high as it is here right now, 30.78 and is -38 degrees below zero, and a track elevation (Airport) of 48 feet above sea level........humidity is ZERO as all the moisture has frozen out of the air on to the ground! Wonder what kind of DA that calc's out to? Reckon my junk would hook on Hoosier's in these conditions :) in Deadhorse, Alaska!

24.3??? Where are you.....in the eye of a category 10 hurricane?:D I don't think a barometer of 24" Hg is possible.

LMAO,,, :D :D

Are them 30+ numbers corrected or station??
If corrected or what you see on TV they don't mean anything to your engine,,

The norm here is 28.1-28.6 station or uncorrected give or take & I am at 1700'

Here is a little excerpt from one of the links below, good reading on both ;)

"Q: What are all the all-time records for high and low barometric pressure in the USA? A: Using average sea level pressure of 29.92 inches of mercury as a point for comparison, the highest barometric pressure ever recorded in the USA was 31.85 inches in Northway, Alaska, in January 1989. The lowest barometric pressure ever recorded was associated with the landfall of the Labor Day hurricane in Key West, Florida in 1935, which registered a minimum pressure of 26.35 inches of mercury. Both are also records for North America.
It is likely that tornadoes have had lower barometric pressures, but they have not become part of the official record.

Learn more about atmospheric pressure on this USATODAY.com resource page.

Take that back about Alaska...looked at the wrong chart. At 4 am this morning Alaska time there was a corrected sea level pressure of 30.92"at a place on the NW coast.
Since AK69 is at sea level, it will be very close to uncorrected pressure. The other correction factors used to calculate corrected sea level pressure on weather maps include temp, relative humidity and gravity ( it varies very slightly from place to place)

18,000 * 14.94 100,000 0.329

Out of one of Mikes links, my 24.3 was uncorrected at 5300 ft and is what we really want to know....and BTW my corrected right now is 30.56. ;)

The confusion is that they always correct it

I have got to get out of here! My truck has been running 7/24 for the last two week, only shuts off to fuel.

Cool dense air makes power, it will also cause your ears to snap off! :)
