TS= No fly!


“TS IMPLY SEV OR GTR TURB SEV ICE LLWS AND IFR CONDS”

What is TS?  Thunderstorms!  And when I see TS on my DUATS report, that’s an easy decision to not fly.

CSC DUATS (Computer Sciences Corporation Direct User Access Terminal Service) is an online aviation weather service available to all licensed pilots and student pilots provided by the FAA.  DUATS is my first source of weather and NOTAMS,  (notice to airmen) providing me with all the pertinent information for my route of flight. In the precautionary statements for every weather report, you will see the above statement.

Translated: ” Thunderstorms imply severe or greater turbulence, low level wind shear and instrument conditions.”

So when you see TS in your weather report, you can expect all of the hazardous conditions stated above.  And flying in these conditions, especially in small aircraft, is not fun!  AOPA has a great webcast on this subject and it is very informative. You can also earn a credit for the WINGS program through the FAA.
