Thanks to the efforts of engineers such as Ryland S. Barlow, Thomas H. Watson and others at the US Army Aviation Applied Technology Directorate, Ft. Eustis, Virginia, a MS Office Excel Workbook has been developed that emulates the obsolete BASIC code of the Trajectory Analysis Program utilized in the 1990 report "AIRCRAFT DEBRIS TRAJECTORY ANALYSIS" published on this website.
This Excel Workbook rapidly computes the down range potential of of specified debris and present this information in a graphical and text format.
|Debris Trajectory Analysis|
|based on Hugh Oldham's BASIC TAPS program, v. 1.10, 8/20/90|
|Trajectory analysis for aircraft debris.(http://proairshow.com/aircraft_debris.htm)|
|Modified for MS. EXCEL calculations and display, 10/21/02|
|By T Watson, Aviation Applied Technology Directorate, USAAMC, Ft. Eustis, VA|
|Excel edited 10/23/02 by Hugh Oldham to expand down range capability.|
|WARNING: Numbers do not take into account small objects splintering off of aircraft Debris.|
|Directions: Fill in requested information in the highlighted cells below.|
|Trajectory Paths are displayed below, and in the worksheet titled "Trajectory Chart."|
|Calculations are in the worksheets titled by their respective angles.|
