Altimeter Question

[Pilot84]

Need help with this one. If you descend from Fl290 to 11,000 and do not reset your altimeter how far off will it be?

[Doug Taylor]

What's the altimeter setting?

That's easy, it's the difference between what it is and what it should be!!

If the altimeter setting is 29.92, then there is no error, otherwise, I have no idea.

200 feet!





Nah, roughly 9.3 feet per 0.01 inHg difference from the local altimeter.

Baro-Corrected Altitude = Pressure Altitude + 27672*( (Local Setting - 29.92)/ 29.92 )

Your tapeline (geometric) altitude will still vary with temperature, but that's the relationship for a barometric altitude.

That reminds me of something funny i heard:

ATC: "N123AB, say altitude."
3AB: "Altitude"

"3AB, confirm ready to copy telephone number"

"Roger, I have your request"

I'm going to have so much fun my last day as a professional pilot.
