What is an AWOS? Automated Weather Observation System Computerized system that automatically measures weather parameters Prepares a weather observation (METAR) and broadcasts the information to pilots Observations are real-time; broadcast to pilots is updated once per minute Broadcasts performed over discrete VHF frequency, or other NAVAIDs such as voice-capable VOR or NDB

AWOS & ASOS Automated Weather Observation System Owned and maintained by the airport / municipality Usually installed at General Aviation airports Ongoing purchases and installations Automated Surface Observation System Owned and maintained by FAA/NWS/DOD Usually installed at commercial service and reliever airports Manufacture and installation completed in 2004

AWOS Certification FAA Certified as official flight weather for an airport Advisory Circular 150/5220-16 (AWOS for non-federal applications FAA – Mike Monroney Aeronautical Center Oklahoma City, OK ) Description Certification Standards Installation Operating Instructions Training Programs Annual System Revalidation AWOS Siting Order 6560.20

AWOS Levels and Capabilities AWOS A Altimeter Setting Only AWOS I AWOS A plus temperature / dew point wind speed and direction, density altitude AWOS II AWOS I plus visibility AWOS III AWOS II plus cloud height and sky condition New Requirement – Tipping Bucket – AC Rev D AWOS III P AWOS III with present weather capability AWOS III PT AWOS III P with thunderstorm detection AWOS IIIPTR AWOS IIIPT with runway surface condition sensor AWOS IV All previous levels plus freezing rain sensor

Common Siting Criteria Non-Precision Approach Airports (primary surface of 500’) From 1000’ – 3000’ from the threshold of the primary runway. From 500’ – 1000’ from the centerline of the runway. Precision Approach Airports (primary surface of 1000’) From 750’ – 1000’ from the centerline of the runway. For the wind sensors there is a 500’ radius clear zone around the AWOS. The wind sensors must be 15’ above anything within the 500’ that blocks more than a 10 degree angle. The wind sensors are normally mounted at 32’ AGL which means nothing over 17’ high within 500’.

AWOS Project Timeline Process for new AWOS requires approximately 9 months to 1 year FAA Siting Approval (2 months) VHF Frequency License (2 months) UHF Frequency License (3 months)(If required) Equipment Manufacturing (2-3 months) Installation and Commissioning (1 week)

AWOS Installation Visibility/Present Weather Wind Sensors Rain Gauge Temp/Humidity Ceilometer Barometer VHF Radio UPS

Stand-Alone vs. Split Configuration ACU – Stand Alone Only local display is indoors Fewer components Phone line at AWOS site location VHF Radio transmitting to pilots at AWOS site location Split Phone line at FBO / terminal building Higher cost (for DBT system) / more components (processor inside) VHF radio located at FBO / terminal building

Stand Alone – ACU All data acquisition, data processing and voice processing is performed at the AWOS sensor site.

Split Configuration This configuration splits the function of the Internal Processor between a data collection package (DCP) located at the AWOS site and a voice data processor (VDP) typically located indoors.

How to obtain an AWOS? AIP funding –embed within a larger project BCA – Benefit/Cost analysis Bidding process – how to get what you want via the engineering / consulting process Private Money – purchase what you want Ask Vic nicely…..

AWOS Maintenance DBT offers full Service 3 Tri-Annual inspections – one annual with the FAA Maintenance is Required to keep AWOS on the air Trained and Certified Technicians FCC-licensed Manufacturer trained FAA certified DBT offers full Service Proactive Maintenance Software program – RM3 – to automatically monitor all AWOS observations remotely Initial response time of no more than 24 hours during normal business hours

NADIN What is NADIN? Single communications link to distribute your weather data to every possible outlet = FAA WMSCR AWOS data available through: Flight Services DUATS Air Traffic Control Avionics – Ground-to-Air Weather Pilot briefing systems Internet sources – weather.com, ADDS, etc. The Weather Channel Foreflight App Local observation available for National Weather Service forecasting Remote monitor and trouble-shoot
