Select the Inputs to be changed

The Inputs Tab is used to designate which analysis inputs you want to vary prior to each analysis run.

In this case we want to vary:

The time the rocket turns on.
The time the rocket turns off.
The Quandrant Elevation you are firing at.

Click on the first blank row on the field column. This list box contains all of the inputs that are needed to drive the trajectory program. Find the three fields listed above.

After selecting the input fields, you now can modify the units displayed to make your input task easier.

Click on any of the unit fields and a dialog box (like below) will be displayed for you to make your choice.
