Negative altitude indication

[UnAnswerd]

Has anyone ever flown below sea level, and did you see a negative indication on the altimeter???

...if you turn the baro pressure adjustment far enough you'll see it wind below zero; same thing happens when below sea level!

I live slighly above sea level. I've gotten in planes that haven't flown for a couple days and the altimeter read below sea level because of the pressure changing.

Yup. KTRM, ele -114

You'll probably be able to add KMSY after today.

Yep. I was going to mention Thermal, CA as well.

Flew in there many times, many years ago. Great airport...loooong runway.

The FBO used to be LaQuinta Resort, or they were closely affiliated with the resort.

I'd fly customers in early in the morning, play 18 holes of golf and be home in time for dinner.

Re: the second part of the question....

Analog altimeters don't have any special indication for below sea level. The needle just keeps on going below zero feet and begins reading in reverse.
On glass cockpit aircraft, there's usually an indication that you're on the backside of the altitude scale. On my plane, a yellow "NEG" tag will appear at the bottom of the altitude tape.

I figure I've got a negative attitude when I quit wearing my hat and don't shine my sh...

What's that? Negative what? Oh.

Never mind... TC

I flew below sea level once but it was hard to see the altimeter with all the water in the cockpit!
