I've been down to 22.142 gallonsHey if you can get the photo then by all means.
Next month we can have the max inclination, and keep going. My personal favorite and a throw down challenge to the staff at IA, how low can you go with the fuel tank and not run out. But that’s for the future
Home sweet home. DRGW. (Denver and Rio Grand Western historic narrow gauge railroad to the rest of the world) You're local so I won't insult you - but be ready to be stuck for days and nights just in case. I've camped in snow in Rico in Elk season.
Best laid plans...hahahaha I was in NM in May 2022 and everything was burning. At least you won't have to worry about that. Nice map and chart.
Yes it fun to take out of towner on Durango Silverton train, even just up to Cascade Canyon.
I gotta win the lowest altitude because my altimeter says I’m below sea level most of the time here in Florida. Dealer says the alternator works on barometric pressure so it doesn’t function correctly in Florida. This makes no sense to me, can this be true?
Just did the same trip
Alternator???? Damn spell check Altimeter,
Maybe use the tunnel that goes under Cheyenne Mountain?
yes. in general youre within the pressure deviation detected by a mild cold front. statistically, you're always at sea level.
Altimeters need to be calibrated to adjust for the local air pressure which fluctuates based on atmospheric conditions. I would imagine the altimeter in the IG is set to standard of 29.92In/HG (inches of mercury)- so unless the local air pressure happens to be 29.92 in/HG the moment your glance at the cars altimeter there will be an error. Higher pressure will cause the altimeter to read low (what you are describing with the below sea level indications), and lower local pressure will cause it to error high. In order to get an accurate reading on a barometric altimeter you would have to know the current local altimeter setting and calibrate it accordingly like what has to be done in an aircraft. This is why pilots must get the local altimeter setting from ATC or via ATIS prior to departing, arriving, and airfield, or transiting different sectors of air space. This setting is set in the altimeter via a small knob and displayed in the kollsman window as depicted below.
That’s a Seinfeld episode! Do it!!!Hey if you can get the photo then by all means.

Kollsman! Nice company. I worked for them. Right across from the Bud brewery.Altimeters need to be calibrated to adjust for the local air pressure which fluctuates based on atmospheric conditions.

1/10 of an inch of mercury accounts for about a +/- 100' error so on an extreme low or high pressure day (such as ahead of or after a storm passage) the error can be quite significant. Kind of silly to place a non adjustable barometric altimeter in a vehicle- should have maybe gone off a GPS signal to be more accurate.

In a breakfast cafe in Kansas a couple of guys were telling road stories about driving big rigs over passes in blizzards. I was only sort of impressed until I realized the guy didn't say "Donner" he said "Brenner" and it was in an army 6x6. Brenner isn't high altitude but is was funny.
