Yes, great idea.


I thought so.


Take an altimeter and set it on a table. Don't move it!

Turn the knob that adjusts the pressure scale to one extreme. Record
the
indication on the face of the altimeter. Now turn the knob to the other
extreme of travel. Record the indication on the face of the instrument.
Now the big question: which value recorded is the altitude at the level
of
the instrument?


One step at a time. Let's see where you are in your understanding of
altimetry before we move on. Answer the questions I posed to Neil Gould.

Yes, one step at a time. Tell me how an instrument that indicates its own
altitude can indicate two vastly different values without changing its
altitude? It is a very simple question.

Which altitude changed? Indicated altitude? Pressure altitude? Density
altitude? True altitude? (Does one presumes WGS84 when speaking of true
altitude?)

Let's answer the questions in the order they were asked.

Ok, I understand that you don't have an answer.

Then you understand incorrectly. If I'm to help you achieve a proper
understanding of altimetry you'll have to let me run the class.

Your opinon of this is not shared by at least a few here, including me.


It's not a matter of opinion.



Considering the definitive answer to the original question provided by
Kev, and the fact that the presented information agrees with my
understanding and usage of the terms, I think it puts the question to
rest.


I'm glad you're content.

We don't let students teach classes here.

I used them correctly.

Perhaps your understanding of them is
incorrect.

Good. Now, answer the questions and we can get back on track with your
education.

That seems reasonable.

But what if the instrument itself is 100 ft tall?


Then it wouldn't fit in the airplane.

It could fit in a balloon.
