Europa-List: Airspeed Calibration

[Ronald J. Parigoris <rparigor@suffolk.lib.ny.us>]

I was reading an article on airspeed today.

It talks about most likely having to calibrate your pitot static system, and
calibrate your airspeed indicator.

I understand, why you may need to do this.

What do you physical change/do to pitot static system and or airspeed
indicator?

Thx.
