Question #1: How would a transponder/static check
screw up my airspeed? Was this just coincidence?
Connections were likely loosened during the check, and weren't tightened
correctly. Perhaps a bug or some dirt were lodged in the system and were
loosened during the check. Have it rechecked before flying again.
Question #2: How do
you check accuracy of an airspeed indicator?
Here is where familiarity with your aircraft is essential. If you know it
always gets a certain airspeed at a certain power setting and weight, you
can get a good idea. You can't check exactly, though, and that's why you
need to have a shop you trust check it annually.
Question #3: How long
should you go before replacing an airspeed indicator?
Have a shop check your system. They can tell you if the indicator is bad,
but that's rare. More often it's the pitot-static system piping.
