Tri-annual Performance Verification and Maintenance Checks will consist of:
1. Viewing the system data outputs on a HHDU and at the DATU display screen to check
for missing data and/or error status reports and listening to the phone and Unicom voice
outputs to verify the system data outputs are as expected for the specific Belfort AWOS
configuration options installed at the site.
2. Cleaning the DATU computer and verifying that the computer power supply, processor
fans and Atomic clock and PC clock are functioning properly.
3. Download and install any Windows OS Updates.
4. Cleaning and calibrating the visibility and ambient light sensors, if installed.
5. Visually inspecting the Tower assembly for obvious damage and inspecting the
obstruction lighting to determine it is functioning properly.
6. Adjusting, correcting or replacing any defective LRU components identified during these
tri-annual checks.
Annual Performance Maintenance Checks will consist of:
1. Completion of all Tri-annual Performance Verification and Maintenance Checks.
2. A confidence verification of the Temperature/Humidity sensor, and Wind Speed sensor
outputs by comparing these outputs to the reported outputs of a calibrated Kestrel 3000
weather instrument.
3. A confidence verification of the Wind Direction sensor by verifying that True North is
reported when the vane is aligned in a True Northerly direction.
4. Verifying the accuracy of the Dual Barometer pressure sensors by comparing the reported
Belfort AWOS output to the output of a NIST traceable, calibrated pressure standard.
Recalibrate the sensor if needed.
