thunderstorms and displays the activity on the Multi-Function Display.
The system consists of an antenna located on top of the fuselage just
forward of the rear window and a processor unit mounted under the aft
baggage floor. The antenna detects the electrical and magnetic fields
generated by intra-cloud, inter-cloud, or cloud to ground electrical
discharges occurring within 200 nm of the airplane and sends the
"discharge" data to the processor. The processor digitizes, analyzes,
and converts the "discharge" signals into range and bearing data and
communicates the data to the MFD every two seconds. The
Stormscope processor is powered 28 VDC through the 3-amp
STORMSCOPE circuit breaker on the Avionics Non-essential Bus.
