Vspeeds, IAS, and TAS

And there I was thinking EAS was Estimated Air Speed, you know the one when your pitot is blocked:doh:

You should be able to do a safe circuit without airspeed indication. Nev

There you go. Now we are all better informed.

 

But it could be that your estimated air speed was equivalent to the equivalent airspeed and in that case your estimation would be esteemed to be unequivocal.

I have found EAS. It is CAS corrected for compressability error. I hadn't realised how fast your modern ultralights are going.No doubt if you want TAS while you go transonic you will need EAS.

I said what it stood for in post 14

I saw that Dazza, I just thought it was irrelevant to ultralights.

Well we hit 188 kts today! Admittedly that was speed over ground. Isn't it amazing what a 40 kt tailwind does to your speed?

Ultralights?? Where does it say that this forum or this thread is just about ultralights?
