Its an E6B flight computer and plotter that you can use to figure the gallons of fuel you need for a certain distance, you can compute how long your flight will be with winds aloft, density altitude, ground speed indicated air speed etc. They were called the whiz wheel and plotting slide rule

Exactly!!! If Star Trek is any indication, the E6B could be around well into the 23rd century. In the Star Trek episode "The Naked Time," Mr. Spock uses an E-6B to calculate the time of impact between the Enterprise and a planet. In the episodes "Mudd's Women" and "Who Mourns for Adonais?" he is again seen holding an E6B. Warmest Regards, Sandy :)

Aviation Circular Slide Rule, E6B Flight Computer. Carried one in my leg pocket of my zoom bag for years. Sucker does everything! Time/distance. Wind drift, DA/PA, True Speed, CG, Holding times and Mach.

Wow, that’s cool! I guess even Spock wanted to know his fuel burn rate on the Enterprise! Lol, does the view screen qualify them for VFR?
CPO Glenn Moss
Yep.

It's a slide rule. Slide rules come in many forms for a variety of uses. For example, nomographs are really nothing more than slide rules printed on paper, in which you use a straight edge to do things like temperature correct electrical resistance readings or calculate chemical additions.

There are more types of slide rules than you can shake a pointed stick at.

This one I recognize as a flight computer, only because I just recently discussed this very thing with a brother of mine just last month (he used to fly F-4 Phantoms for the Marines). It's an E6B, specifically.

Nitrox bottom time calculator ? lol
Capt Seid Waddell
I'd have thought that Spock would have gone digital by then.

. Back before calculators and computers the military had all kind of devices that were swept away. I know I used them
PFC Johnson is using a Graphic Firing Table to determine the firing data for artillery

Actually - this is a WWII generation E6B flight computer. Warmest Regards, Sandy :)
