EXECUTIVE SUMMARY

The Automated Surface Observing System (ASOS) is a weather collection and displaysystem that will be installed in airport traffic control towers (ATCT) and atlocations designated by the National Weather Service (NWS). The system is beingprocured, installed, operated, and maintained by the National Oceanic andAtmospheric Administration (NOAA) for the Federal Aviation Administration (FAA)under a Memorandum of Agreement (MOA). The NWS is a service operating under NOAA.Weather observer personnel who work for the NWS, will eventually be phased out oraugmented when ASOS is commissioned.

This report encompasses the results of the third evaluation of the ASOS and theresults of a followup ad hoc meeting after the evaluation was completed. The thirdevaluation of the ASOS was accomplished at Will Rogers World Airport, OK; WileyPost Airport, OK; Tulsa International Airport, OK; Lincoln Municipal Airport, NE;Johnson County Airport, KS; Rosecrans Memorial Airport, MO; and Grand IslandAirport, NE. Data was collected via questionnaires completed by air trafficcontrol specialists (ATCS) at the seven airport sites and analyzed by personnelassigned to the FAA Technical Center Weather and Primary Radar Division, ACW-200.

The evaluation responses indicated the ATCSs felt the ASOS, as it currently exists,does not help in performing weather observations and is not ready for operationaluse. The results of the evaluation led to agreed upon changes to the ASOSidentified at the ad hoc meeting which will be prioritized by the FAA WeatherSensors Program Office, ANW-400, and forwarded to NOAA and the prime contractor foraction.

INTRODUCTION

The Automated Surface Observing System (ASOS) is a computer-based system consistingof an array of sensors and communication ports. The ASOS is engineered to providecontinuous automatic airport weather observations to tower air traffic controllers,via alphanumeric displays, and to pilots, via radio or phone. It will generate1-minute observations, hourly Surface Aviation Observations (SAOs), and specialand local observations. The ASOS will report wind speed and direction; pressure;temperature and dew point; visibility to 10 miles; selected obstructions to vision;precipitation identification, intensity and amount; freezing rain; and skycondition to 12,000 feet.

fhe intent of the ASOS program is to implement automated weather observing systemswhich employ today's technology as a means of improving the weather servicesprovided to the National Airspace System (NAS). At towered airports, ASOS willimprove on the weather services already provided by relieving National WeatherService (NWS) staff of the manual collection of weather data, and by providingstandardized, and more objective observations while ultimately decreasing cost.At nontowered airports, ASOS will provide weather observation services that arecurrently not available.

The Federal Aviation Administration (FAA) has a planned requirement for at least537 ASOSs of two different operational levels; (1) a nontowered or small airportlevel where there is currently no federal weather observing program, and(2) towered or larger airport level whe-e there is an existing federal weatherobserving program.

PURPOSE.

This was the third evaluation of ASOS and was conducted at the request of AirTraffic Plans and Requirements Service (ATR), Washington Headquarters at thefollowing airports:

1. Will Rogers World Airport, OK;2. Wiley Post Airport, OK;3. Tulsa International Airport, OK;4. Lincoln Airport, NE;5. Johnson County Airport, KS;6. Rosecrans Memorial Airport, MO;7. Grand Island Airport, NE.

The selection of these particular airports was based upon:

1. location (NWS area of most diverse weather patterns);2. tower activity level;3. multiregion area (Southwest Region, ASW, and Central Region, ACE).

Of the seven sites selected, four were commissioned ASOS sites and were required touse the ASOS data for official weather for that airport. The remaining three siteswere either noncommissioned ASOS sites that continued to use NWS weather reportingor Limited Aviation Weather Reporting Station (LAWRS) sites that compiled theofficial weather themselves. Prepared scenarios were used by these three sites inorder to manipulate the ASOS during the evaluation.

EVALUATION

EVALUATION ISSUES.

Controllers at the 7 airports (totaling 82 personnel) were requested to evaluatethe ASOS in order to:

1. assess the ASOS in an operational environment;

2. prioritize eight* issues/requirements concerning the Operator InterfaceDevice (OID) and Controller Video Display (CVD) that were identified in thetwo previous ASOS evaluations and to reveal any new issues;

3. determine impact on controller workload;

4. assess display readability;

5. assess equipment fit in the operational environment; and

6. assess content and format of the CVD display data.

EVALUATION CONDUCT.

The controller evaluators at each of the seven sites were briefed about theevaluation and then given the questionnaires at the conclusion of the evaluation.The questionnaire was designed using positive statements reflecting theissues/requirements previously mentioned. The controllers were given up to 60 daysto evaluate the system. The evaluators had the choice of agreeing or disagreeingwith the questionnaire statements; depending upon their evaluation of the system.If the evaluators disagreed with the statement, they were requested to elaborate onwhy they disagreed.

The evaluation questionnaire consisted of four parts: (1) ASOS Questionnairefor the Control Tower Cab which was administered to all seven sites; (2) TRACONSupplemental Questionnaire which was administered to those sites having a TerminalRadar Approach Control (TRACON); (3) LAWRS Supplemental Questionnaire which wasadministered to the two LAWRS facilities; and (4) Summary Questionnaire which wasfree-form and entirely voluntary. These questionnaires are contained inappendix A.

The equipment evaluated was the Operator Interface Device (OID), the ControllerVideo Display (CVD), the OID Keyboard, and the Operator Notification Device (OND).

(*Note - There are nine issues identified in the Air Traffic Operational Evaluationof the ASOS Displays plan. The ninth issue concerns the use of a telephone as partof the ASOS hardware for transmitting and monitoring ASOS data). The issue was notevaluated since the ASOS data was not being broadcast at any of the seven sites.

RESULTS OF EVALUATION.

The numerical results of the evaluations were compiled and are contained inappendices B and C.

DISCUSSION

AD HOC MEETING.

Following the evaluation, an ad hoc meeting was held January 12 through 15, 1993,at the FAA Technical Center. The ad hoc meeting was established to discuss theevaluation results. Members who attended represented the seven air traffic fieldfacilities who took part in the ASOS evaluation, Air Traffic (AT) personnel fromWashington Headquarters Weather Sensors Program Office, NWS, National Oceanic andAtmospheric Administration (NOAA), FAA Technical Center's Weather/Primary RadarDivision, ACW-200, and support personnel. (See list of attendees in appendix D.)

The objectives of the ad hoc meeting were to:

1. discuss the results of the third ASOS evaluation;

2. Prioritize short- and long-term modifications to the ASOS that will be requiredin order to deploy the equipment to the remaining tower facilities;

3. develop a time schedule to incorporate the modifications.

AD HOC DISCUSSION.

The results of the evaluation responses were presented to the ad hoc group. Thegroup debated the relative merit of keyboard and display devices. The OlD and CVDwere compared with generic Information Display Systems (IDS) and previouslyinstalled systems such as System Atlanta Information Display System (SA-IDS).According to AT headquarters personnel, there are already approximately 150 SA-IDSdevices installed in various control towers and they would prefer having theweather data sent to an IDS type terminal rather than use the CVD.

There is a concern too many display monitors and keyboards exist in the controltower. Some towers have up to five different displays in the tower cab notincluding the ASOS OlD and keyboard. ATC tower personnel would prefer to reducethe number of tower displays by combining several ATC functions into one IDS.

Discussions by the committee also included the need for a source of "real-time"wind direction and velocity. Controller representatives stated that a pilot needsto receive real-time winds, not averaged 5-second delay winds. The NOAArepresentative responded that if the FAA wants ASOS to provide real-time winds,then the FAA must submit this requirement to the NWS.

The short- and long-term objectives list was updated throughout the remainder ofthe meeting. The following items surfaced for discussion or were added to the

requirements list:

3

1. Controller representatives asked that an alarm be generated when the weatherobservation is being transmitted. This was added to the requirements list.

2. Controller representatives expressed concern that too many special observationsare being generated. This results in increased responsibility as well as increasedworkload for the controller. AT is working on resolving this problem.

3. Controller representatives felt that they should have access to weatherobservations from other airports. The NOAA representative responded that ASOScould be modified to provide this information if a new requirement was generated.

4. Controller representatives stated they have little confidence in the ASOSweather data compared to reporting means which were used previously. They preferthat the observation be displayed in the standard one-line format. It was pointedout that the CVD has a display limit of 240 characters. This led to a lengthydiscussion on the relative merits of an IDS type display versus the CVD. Becauseof the limited space available on the CVD, the comments in the weather observationare not displayed at the controllers' positions in the TRACON (i.e., the CVD).Consequently, only the controllers in the tower see the weather observationcomments on the OlD.

5. Automatic Terminal Information Service (ATIS) will be interfaced with the ASOSas a part of the tower automation program.

6. The controllers have concern they will have to augment weather if the NWSweather observers are removed. This increases controller workload andresponsibility. This makes the controllers role more of a data distributor whichtakes away from their primary role of controlling aircraft. The NOAArepresentative responded that many of the special observations that requireaugmentation are as a result of less than ideal sighting locations. Therefore,controllers may be required to override incorrect ASOS data. AT representativesstated they are working on this issue.

7. Another problem is when a controller wants to review data, he must log off theOlD in order to get to the data review function. NOAA will take action to providecontrollers the Review Data function as a new requirement.

8. Data from the evaluation was inconclusive, concerning the controllers' reactionto having Hot Key functions, in that the sample was extremely small; however, thecontroller representatives at the meeting were strongly in favor of Hot Keys. TheFAA will take action to identify to NOAA which functions (thunderstorms, hail,tornaoes, verga, volcanic ash, etc.) they would like included as Hot Keys.

9. The ONDs were evaluated at two of the tower locations. They resemble arotating flashing beacon and are envisioned for use in areas that have a noisyenvironment where audible alarms would be of little use. Controllers were not infavor of the use of ONDs.

The ad hoc team made the following conclusions:

1. Short- and long-term recommendations for improving the ASOS for AT use weredeveloped during the ad hoc meeting. A short-term requirements schedule wasdeveloped and is contained in appendix E;

4

2. The FAA must determine if .hey want ASOS to provide real-time wind velocitydata in lieu of what is currently displayed;

3. NOAA will provide feedback to FAA field personnel concerning trouble reportsand corrective action taken;

4. ANW-400 will address the possibility of replacing the VT-320 OIDs with Intel486 compatible computers in order to reduce interface problems;

5. ANW-400 and NOAA will address removal of the requirement of the controller tosignoff in order to review data;

6. The FAA will address the issue of Hot Keys. ANW-400 will provide informationon the number of Hot Keys, type of information, and which functions need to beprovided to NOAA;

7. NWS to reemphasize the NWS requirement in Handbook No.7 that the weatherobserver make an observation that is representative of the airport conditionsand issue a special observation when appropriate.
