Stormscope System
1. General
This Section tells you about the stormscope system that can be installed in the DA 42 NG. Refer to
the manufacturer’´s manual for more data about the equipment.
The stormscope system consists of the following items:
)
Stormscope processor.
)
Stormscope antenna.
2. Description and Operation
The WX-500 is a passive sensor that listens for electromagnetic signals with a receiving antenna. The
antenna detects intra-cloud, inter-cloud, or cloud-to-ground electrical discharges within a 200 nm
radius of the airplane and sends the resulting 'discharge signals' to the processor. The processor
digitizes, analyzes, and converts the discharge signals into range and bearing data. This information
is stored in the storm buffer.
A. Stormscope Processor
The stormscope processor is tray mounted and is located under the passengers’ seat.
The AVIONICS BUS power to the stormscope system. The ELECT. MASTER switch and the
AV. MASTER switch must be set to ON to supply power through the WX-500 circuit breaker to the
stormscope system.
The processor houses the lightning data acquisition circuitry as well as the circuitry necessary to
process heading information and communicate with the G1000 system. All WX-500 functions are
controlled through the MFD of the G1000 system.
B. Stormscope Antenna
The NY-163 stormscope antenna is located on the horizontal stabilizer. The antenna is a combined
cross-loop and sense antenna. The antenna is sealed against environmental extremes and is non-
repairable.
