WADDS
PEPL Wind/Altimeter Digital Display System
The PEPL WADDS PEP8901 system provides real-time distribution of current Altimeter Setting Indicators (ASI) and wind information. The system consists of a wind sensor, Sensor Transmitter Unit (STU) and Console Display Unit (CDU). The STU processes wind sensor information, measures atmospheric pressure and converts measurements into ASI values for display via the CDU.
- for aviation (runway and aerodrome) weather reporting applications
- real-time distribution of current Altimeter Setting Indicators (ASI) and wind information
- wind sensor comprised of an anemometer and remote processor
- STU - Sensor Transmitter Unit
- CDU - Console Display Unit
The wind sensor transmits wind information to the remote processor which averages the vector components over pre-set intervals and sends this to the STU. The STU processes the wind information, measures atmospheric pressure and converts measurements into ASI values. The STU transmits the ASI information to the CDU for display.
