What would cause my airspeed indicator to be stuck at zero all the time? Last Updated: 12/17/2008
A common cause of this is a problem with the Pitot source. If the line from the Pitot tube has disconnected, then pressure will not be applied to the instrument.
If the Pitot tube is clogged, then pressure will not be applied to the instrument.
It is common for Leaf Bugs to build nests in Pitot tubes and effectively clog them.
