Precision Preset Pressure Reference Unit
The heart of any air data computer is the pressure sensor itself. The accuracy of the entire system is based on the sensor. This little box seems to be a reference unit which uses the standard conversion that 100 Knots air speed is equivalent to a pressure of 16.36millibars.
This unit dates from the original Marconi Collection Ref: 2034
