HA! That happened to me last month! An ANT got into the pitot tube and blocked the air flow. You have something keeping the air inside the tube. This is common with ice buildup on the tube. An AN=NT was a new one for me!
Airspeed, altimeter, and vertical speed indicator
An airspeed indicator is an aviation instrument which displays an aircraft's current airspeed.
The airspeed indicator or airspeed gauge is an instrument used in an aircraft to display the airspeed in knots
It's an airspeed indicator that compensates for outside temperature and barometric pressure at altitude.
the airspeed indicator works by measuring the increase in air pressure caused by the moving aircraft
