IAS EAS CAS MACH | Airspeeds For Aviators | Aviation Explained

There are a lot of airspeed acronyms in the world of aviation and each one has a purpose. There are also a lot of people that try to explain them out on the Internet. And none of them really did it for me. It took a lot of research on my part before I finally got to a point where it made sense. There are others out there on the same journey and I thought I would help them out by sharing what I've learned and hopefully explain it right on the first try.

    Another excellent vid, Solly. I didn't realize just how big of a difference GS can be between the IAS at altitude like that. Very helpful.

    Same here and it's why I wanted to share what I found out. Glad it was helpful.

    EAS is the one that gave me the hardest time. All the others were pretty easy to understand once the definitions are parsed into layman's terms.

    To everyones info Ground Speed is the one we would use if we wanted to calculate how long it takes to get somewhere.

    Small tip, the F-16 can show calibrated, true, or ground speed in the hud. The switch is found on the HUD panel just to right of the stick. Though in DCS ground speed seems to be broken.

    Yeah, I know that switch and I agree. The last time I tried it there seemed to be some problems with it. Thankfully, the speed displayed on the DED seems to be accurate.

    Super informative thanks for the video! You do a great job explaining this stuff. Btw how do my ancient virtual MiG15 and F86 calculate Mach number without all those fancy calculators?

    That's a great question. The engineers at the time understood the Mach number quite well. It's fluid flow velocity over the speed of sound in the local medium. An easier way to think of that is Indicated Airspeed divided by the speed of sound at a given altitude. Both of those numbers were available to the instruments of the time. So a mechanical connection between those instruments could be used to display a Mach number. Today, we can be more accurate by using TAS for the speed component and air temperature to gauge the air's actual density. This is thanks to the better electronics we enjoy. That will give us a more accurate Mach number. But what was available in the '50s would give pilots a number that was close enough.

    Funny, when people talk about the E6B nowadays, they are usually refering to the digital incarnation. My 40 year old "whiz wheel" E6B still works great though and it has a permanent spot on my flying desk :)

    It's easy to get spoiled on the new stuff, but I think people that can use a E6B understand what's going on a little better.
