WEATHER DISPLAY
 MADE iN WINDOW
 OF PAN AMERICAN

Pan American has a very interest ing window display of equipment used hy the Weather Bureaus all over the world. The teletypes shown in the display are of the more recent type being used in the Territory by the Weather Bureau and the Army.
 Every certified airline flight is planned and operated with safety as the primary consideration. To- ward this end the airline dispatchers. the airline meteorologists. the Wea- ther Bureau meteorologists and ob- servers, and the Civil Aeronautics Administration Aircraft Communi- cators all work as a team to insure maximum possible safety to each and every flight. Forecasts for each of the airline terminals and forecasts of icing, turbulence, and winds alott are made by both airline and Wea- ther Bureau meteorologists and cross checked by the pilots and dispatch CTS.
 Airway forecasts prepared by the Weather, Bureau meteorologists at Juneau are transmitted all over AL aska, Western Canada, and the Pa cific Northwest. The airway fore casts prepared by the Weather Bur- eau forecast centers at Seattle, An ohorage, and Fairbanks are giver similar dissemination so that all stations, offices and agencies con- cerned will have full forecast and advisory information at all times
 All of these forecast centers op- crate 24 hours a day every day ol the year. Each center is specifically responsible for certain areas plus certain terminals and also provides advisory information for other sec tors outside their own area.
 Every hour several hundred wea- ther stations take observations oi ceiling, visibility, weather (snow, rain, fog, etc). temperature, dew point, and winds. This information is partially coded and transmitted via teletype to Bureau offices, airline operations offices, and CAA Airway Communications stations.
 The other teletype machine yot see in this display is receiving re ports from all of Alaska, the Aleu- tian Chain, the Pacific Northwest Washington, Oregon and Idsho) and portions of Canada.
 Other teletype circuits bring 1T reports from the remainder of Can ada, the western portion of the Uni ted States, portions of Siberia anc Japan, and reports from ships anc weather reconnaissance planes out over the Pacific ocean and the Gull Of Alaska. Reports are also occas- ionally received from weather re connaissance planes operating be- tween Alaska and the North Pole
 Most of the weather reports com. ing in on the other teletype are pre-, oeded ty a or letter group iden- tifying the station which made tht observation.
