As the AV-30-E ages or is exposed to unusual conditions, the pressure
sensors may age and require field adjustment to maintain accuracy. If
the Indicated Airspeed (IAS) appears to be inaccurate, the Pitot and
Static pressure sensors may have aged unevenly and yielding
inaccurate readings. This may be remedied by executing the PITOT
