I am FAA rated as a Private PIlot and found this very interesting. It's not to be used for anything and is "put away" due to the fragility of it. I also found it interesting that back in the day they called this a computer! This was "state of the art" back then and really a piece of history. I can't believe I have it!December 6, 2019Purchased

I have used it to find density altitude on many occasions; I would rather not use the iPad or iPhone E-6B calculators. This provides more accurate conversions since it is much larger than the density altitude ratios provided on the E-6B.October 4, 2019Purchased

I have very little of his items to remember him by. This is exactly like his calculator he owned. I hesitated to open it, because it had not been opened since it was made in 1942?
It was like a ceremonial process opening a historical item for the first time!
Thank you for preserving history!

- Question and Answer
Browse 1 question Browse 1 question and 2 answersIs there a book to explain how it works?BEST ANSWER: I bought this as a Christmas gift for my son who is a pilot. He had some idea of how this works but he was going to "google" to see if there was anything available that explains how to use it. But he was very excited to receive it - more than the other gifts I bought for him. We were visiting my father-in-law at the Veterans Home & my son brought this to show my father-in-law's friend who was a glider pilot during the war. So as a piece of history, especially for a pilot, it is definitely worth the price.
