altimeter reading

[flint007]

hello all!

can someone help please? Thank You. if i leave an airport with an msl of 5280, and with an altimeter setting of 29.96, what would my altimeter reading be in height, if the altimeter reading is 28.74 once i got to my final destination? Thanks to whoever and all.

4060 feet, assuming you never reset it. I think. But I have the flu, so don't quote me.

Other way around I believe, 6500...high to low look out below. But I am not very intelligent so don't quote me either

I'm going with god. The pressure is getting lower, so the alt is gonna give a higher reading.

BUT I am wasted so don't quote me

That's some wicked low pressure. I'd turn around and go where it's sunny.

Altimeter should read 1220' higher.
29.96-28.74=1.22inches
1"of hg = 1000ft

Come on man. I married a Bostonian....Can't I get away from the WICKED. JUST FOR ONE DAY...

Ah just look at my post count and where I'm from. I just want attention.

I'll go with 6500, as long as you land at the same airport or one with the same elevation.

That high to low stuff did nothing but confuse me. The way I remember is that when you adjust your pressure in the window, the altimeter will go in the same direction as the pressure change (both values will decrease or both will increase). So if you have not changed the altimeter by the time you land, and decide to correct it, you will have to rotate the barometric pressure DOWN which will cause the altimeter to decrease, thus it was reading high before you made the adjustment.

Thank You All for Your replies. i'm in the area of my ground study which requires me to know this stuff as i know i'll be using it when i get my wings. but it is confusing! one area of the study had to do with elevation. at the beginning airport there was the 5280' msl with an altimeter reading of 29.96, and at the destination airport the msl was 890', where the altimeter setting was 28.74. any further comments are definitely appreciated. again, Thank You All for Your responses. and i look forward to be joining You All in the skies when hands on training begins. Thanks All again.

Thank You All for Your responses. and i do hope to be joining You in the skies sometime in the near future when i get my hands on training. very confusing stuff this altimeter re-setting thing. what throws me off is that at my beginning elevation of 5280' msl the altimeter setting is 29.96. when i get to my destination, the elevation is 890' msl and the altimeter re-set is 28.74. i don't know what my altimeter reading in height, should be at that 28.74 setting. i Thank You All for Your responses and i appreciate any and all further comments in for me, this very confusing area. Thanks All again.

AHA! The missing piece of the puzzle was the destination airport elevation. In your example, if you flew from the 5280ft airport to the 890ft airport without resetting your altimeter, it would read 2110ft on the ground at the 890ft airport.

That is why the high to low phenomenon is the most dangerous. If you didn't reset the altimeter and were descending in the clouds, you would have flown into the ground when your altimeter read (and you thought you were at) 2110ft.

What's the temperature? Is it real cold? Think about that.

However, don't quote me since Jack Daniels is sitting next to me.

ok, i think i'm beginning to understand. pressure changes would've caused me to actually crash or come too close to crashing if i hadn't changed the altimeter setting before arriving at the 890' elevation. soooooooo, i should've gotten the correct msl reading from either the airport tower or from some agency, way before i even attempted to chart my flight! well i do Thank You All again for Your responses. and i apologize for not supplying the unknown factor to everyone before submitting my query. just goes to show me that i must have all my facts together--and definitely before plotting any navigations! Thanks again SingleCoil, and to All!
