ASRS Directline  Issue Number 10 : December 1998

ASRS Services on the INTERNETThe ASRS Web Site, started in late 1995, has become increasingly popular with the aviation community. To the end of September 1998, there have been 435,763 "Hits"1 in 154,904 "User Sessions."2 The most popular pages, other than the ASRS Home Page are CALLBACK (ASRS's award winning Monthly Safety Bulletin), ASRS Reporting Forms, ASRS Database Information, and ASRS Directline. Since April, 1997, 14,888 NASA Incident Reporting Forms (in PDF)3 have been downloaded by pilots, controllers, maintenance personnel, and cabin crew. There were 25,114 ASRS Database Report Sets downloaded from February 15 through the end of September, 1998.

New Features in 1998

Ongoing: We will continue to add CALLBACK and ASRS Directline issues in HTML4 and PDF format as they are published.

January 15: Selected ASRS Database "Report Sets" were added to the ASRS Web Site. We have provided twenty individual sets of reports on various issues of topical interest. Report Sets are available in Rich Text Format5 (RTF). The file size for each Report Set will be small, averaging less than 200K, thus download time for users will be minimal.

Each Report Set consists of fifty ASRS Database records, preceeded by a note of introduction, caveats on use of ASRS data, and standard abbreviations and definitions used in ASRS Database records. All Report Sets have been pre-screened to assure their relevance to the selected topic. The Report Sets will be updated quarterly. New topics will be added -- and outdated topics removed -- in response to input from the ASRS user community, and analysis of Web site usage.

Your comments on the usefulness of the "ASRS Database Report Sets" feature would be appreciated, and may be directed to ASRS's Web Site Administrator at webadmin@olias.arc.nasa.gov

 

Upcoming Features in 1999

Research Products: ASRS Research Papers will be provided in HTML and PDF.

Web Pages: The general appearance and functionality of all ASRS pages will be upgraded, and navigation will be made simpler and more intuitive.

Electronic Report Submission: We are planning to introduce a new method for electronic dissemination, and ultimately submission, of ASRS aviation safety incident reports.

Definitions

1 Hit: An action on a web server, such as when a user views a page or downloads a file.

2 User Session: A session of activity (all hits) for one user of a web site. A unique user is determined by the IP address or domain name. By default, a user session is (considered) terminated when a user falls inactive for more than 30 minutes.

3 PDF: Adobe's Portable Document Format, quickly becoming a standard where there is need to transfer exact image documents between various computer platforms.

4 HTML: Hyper Text Markup Language -- the common cross-platform language for web browsers.

5 RTF: Microsoft's Rich Text Format, a format which can preserve formatting between various applications, most notably word processing packages. RTF can be read by almost all word processors, and by many spreadsheet and database programs.
