This book was released on 1984 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceiling and visibility measurements are included in an Automatic Weather Observing System (AWOS) which is intended to satisfy the needs of aviation. The performance of one ceilometer and two visibility sensors was examined to determine whether they can meet the requirements of AWOS systems. The visibility sensors employed two different principles of operation: a transmissometer and a forward-scatter meter. The sensors were field tested at Arcata CA, Sterling VA, and Otis Air National Guard Base MA. During the last portion of the field testing the sensors were interfaced to a commercially available AWOS system to verify the sensor interfaces. The results of the evaluation indicate that the laser ceilometer and the transmissometer were generally satisfactory, but that the forward-scatter meter required additional development and testing because of electronic defects in the units tested. A major goal of the study was to develop and evaluate acceptance test procedures for AWOS ceilometers and visibility sensors. Accuracy and maintenance requirements, standard reference, sensors, and test methods were examined. (Author).

Download or read book Automated Low cost Weather Observation System ALWOS written by and published by . This book was released on 1982 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary objectives of this program was to design a developmental model ALWOS for the lowest possible cost. Reliability and maintenance costs over the life of the system were considered in addition to the initial purchase and installation costs. To this end, field proven, off the shelf components were used wherever possible throughout the system. Another primary objective was modularity of design. The hardware and software were constructed to allow flexibility in interfacing a variety of sensors or adding additional sensors to measure new parameters. The ALWOS as configured at Dulles Airport is a low-cost and flexible system which can provide an automatic weather observation from the data acquisition, processing and display point of view, with the potential for good long-term system reliability. After a period of familiarization with the equipment and dealing with an assortment of system and sensor problems, the functioning of the system became relatively trouble-free. Evaluation of the ALWOS supports the generally accepted concept that automated, low-cost weather observation systems can indeed perform such a function given suitable sensing devices. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A new visibility instrument, the forward scatter visibility meter, has been developed. This report describes the development of the instrument, including the various field tests. Some thirty instruments have been operationally deployed in a network of automatic weather stations near L.G. Hanscom Field in Bedford, Mass. Comparisons between field instruments and transmissometers yield differences of about plus or minus 19 percent. Comparisons with visual observations show differences of plus or minus 34 percent and greater. Analyses of individual cases uncovered difficulties with the response time of observers and with ability to diagnose spatially varying visibility. The accuracy of visibility measurements is assessed and the report concludes by looking at the future of visibility instruments. (Author).

Download or read book The Operational Suitability of the Automated Weather Observing System AWOS at Heliports written by Rene A. Matos and published by . This book was released on 1987 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1985, a series of flight tests were made at the Federal Aviation Administration (FAA) Technical Center to develop siting standards for the installation of Automated Weather Observing Systems (AWOS) at helicopters. The results of this evaluation were documented in the report 'The Siting, Installation, and Operational Suitability of the Automated Weather Observing System (AWOS) at Helicopters'. A questionnaire (OME approved) was distributed through the helicopter operators/managers to the users of the New Orleans Downtown Heliport, Indianapolis Downtown Heliport, and Technical Center Heliport. This report presents the analysis of the questionnaires used to determine the operational suitability of AWOS at helicopters. The results of the analysis of the questionnaires indicate that the AWOS equipment is suited for heliport use. A distinction should be made between the prevailing winds at the landing area and winds in the heliport vicinity. This situation can be resolved with the use of a wind sock in conjunction with the anemometer. The wind sock should be placed near the landing pad to provide surface wind information and the anemometer should be placed as close to the nominal landing decision point height as possible in order to provide prevailing wind information above the height of obstacles surrounding the heliport.

Available in PDF, EPUB and Kindle. Book excerpt: From the bestselling author of The Girl from Munich, a sweeping, dramatic tale of love and identity, inspired by a true story. After enduring the horror of Nazi Germany and the chaos of postwar occupation, Lotte Drescher and her family arrive in Australia in 1956 full of hope for a new life. It’s a land of opportunity, where Lotte and her husband Erich dream of giving their children the future they have always wanted. After years of struggling to find their feet as New Australians, Erich turns his skill as a wood carver into a successful business and Lotte makes a career out of her lifelong passion, photography. The sacrifices they have made finally seem worth it until Erich’s role in the trade union movement threatens to have him branded a communist and endanger their family. Then darker shadows of the past reach out to them from Germany, a world and a lifetime away. As the Vietnam War looms, an unexpected visitor forces Lotte to a turning point. Her decision will change her life forever . . . and will finally show her the true meaning of home.
