Altimeter question

[Lawson Laslo]

Hello I have a WW2 army Kollsmam altimeter in the ‘coupe
I notice there’s a small bug like pointer that goes around the gauge but not sure what it does? Any ideas?
It moves as I set the baro

Tens of thousands of feet?

Tens of thousands of feet?

I don’t think it is because If you look in the center you will see the third smallest arm which reads 10000’

I see it now.

does it freely move without sync to the other hands? If so maybe a reminder bug for altitude clearances

How much does it move as you twist the Kollsman knob?

100,000s of thousands of feet?

Just never know when you may take an Ercoupe into extra orbital flight!

wish i would have known that my altimeter would read above 99,000' for my space flights! Ive been having to use foreflight to get my altitude after passing 100,000 feet msl

not sure, will have to pay attention next time

It's indicating the altitude difference between ISA pressure at sea level and what is set in the Kollsman window.

Here's a link to an old PoA thread that drifted (imagine that ) to discussing this topic.

They did have a rocket powered Ercoupe once.

Just make sure you don't run into this guy and his orbital Tesla out there.

Im wondering about mine also.

Starman!

On Feb 25, 2021 Starman will complete his second orbit of the sun since launch on Feb 6, 2018. Last October it passed within 5 million miles of Mars. ...

Just make sure you don't run into this guy and his orbital Tesla out there.

He's now over 32,000,000 miles from Earth but getting closer.

Who sez a Tesla is range limited.
