Browser/System Requirements

This course must be viewed using a DHTML-capable browser, such as Microsoft's Internet Explorer (IE) 5.0 or higher (Windows only) or Netscape's Navigator (NN) 4.7-4.8 or 6.2 or higher (Windows and Macintosh). (Note: Netscape 6.0 and 6.1 is incompatible.) Macromedia's Shockwave/Flash plug-in or ActiveX controls (already included in most browsers) are required to run the course. Your browser should inform you if the plug-in is needed. The plug-in can be downloaded from Macromedia's site at http://www.macromedia.com/shockwave/download. Additional requirements for normal viewing include sound capability and speakers but closed-captioned and text-only options are available.

Your browser should be configured to load images and play sounds and have JavaScript and style sheets enabled. You can check these settings in IE by choosing "Tools/Internet Options/Advanced," or in Netscape Navigator by selecting "Preferences" in the Edit menu and clicking the "Advanced" setting.

The additional readings and references linked to from within this course point to files in Adobe's Portable Document Format (pdf). The Adobe Acrobat Reader can be found at http://www.adobe.com/products/acrobat/readstep2.html.

What happened to the Aerospace Power Course?

The Air & Space Power Course is an updated version of the Aerospace Power Course that was previously available at this site. Terminology has been updated, more recent examples are used, some sections have been completely rewritten, and new material has been added.

Registered users of the Aerospace Power Course will have to re-register and complete the new Air & Space Power Course if they need a course completion certificate. We apologize for any inconvenience this may cause you, but hope the new course will make your effort worthwhile.

Optimal Viewing Tips

This course was designed to be viewed in an 800x600 pixel screen at true color. Little degradation should be seen at the 16-bit or thousands of colors setting. Eight-bit color or 256 color mode should be avoided. Extraneous browser buttons and controls should be minimized to ensure that the entire page fits on your screen without requiring downward scrolling. In NN for 800x600 modes we recommend display of only the navigation and location toolbars with text only preference set for the toolbars. In IE we recommend display of the standard button and address toolbars but none of the explorer bars. In both browsers we recommend display of the status bar as many contextual messages are displayed there.

How do I start the course?

Choose "Start the Course" from the navigation menu on the upper left-hand side of this page and choose the link "Introduction to the Air & Space Power Course" to begin.

[top]

What if I get a blank screen when trying to load the course?

Macromedia's free Flash Plug-in or ActiveX controls are required to view the course. If the plug-in is not installed (or is an older version), the course will not function properly and may result in a lack of sound or a blank screen. The plug-in can be downloaded from Macromedia's site at http://www.macromedia.com/shockwave/download.

You will need installation privileges for your machine to install the plug-in/ActiveX controls. Many Air Force computer users will need the assistance of a system administrator.

How do I navigate within the course?

Every page in the course, with few exceptions, contains the graphical user interface (GUI) element shown below.

The "NEXT" button will take you to the next page, in a serial fashion, throughout an entire lesson. The word "NEXT" will glow once a page's narration is complete to let you know it's OK to proceed. The "BACK" button, takes you through the lesson in reverse order to that of the NEXT button. It doesn't necessarily take you to the page you just came from, like the browser's BACK button does. For example, if you use the "LESSON MENU" feature, discussed below, to skip ahead in a lesson, the GUI's BACK button takes you to the page that is before the one you are on in lesson sequence, not the one you just came from. Clicking the "LESSON MENU" tab along the left-hand side of your screen, causes a pull-out image to appear such as this one for the "National Security Strategy" lesson:

The yellow triangle marker along the left side shows your current position in the lesson and you can quickly see the layout of the lesson's major points. By clicking an item, you will be taken there directly. For example, if you want to view the "Levels of War" section again, you could click that title to jump right to it. Not every page is directly accessible from the LESSON MENUbut may be grouped with other pages under a common heading. For instance, the "Quiz" section may contain several related pages; clicking on that title will only get you to the first page of the sequence.

The last two conventions worth noting are our links and rollovers. Links open a new window with a reference document, or an internet link site as its content. By opening a new window, you'll never become lost by following a link. Just close the linked document and you can carry-on from where you were. When you place your cursor over a link, you may get a pop-up box with explanatory information such as a page number to see in a reference. You may see something like: "See page 17 (23 of 115)." This means that the page numbered 17 in the document is actually the 23rd of 115 total pages in the .pdf file. Links are usually a pale blue color and underlined.

Rollovers indicate the presence of additional text that expands upon the basic course material. When the cursor is placed over a rollover, a pop-up box appears with the supplementary material. Rollovers are similar in appearance to a link, so when you see pale blue underlined text on a screen, check it out!

How do I control the playback of a screen?

The controls in the upper right corner of each page will allow you to pause or replay the narration and screen activity while viewing the lessons. When pressed, the PAUSE button will light up to indicate that the screen is paused. Press the PLAY button to resume. Press REPLAY to play the screen again.

You may drag the slider control, shown between the BACK and NEXT buttons, at any point during the progress of the page. This lets you reset your playback position on the current page without reloading or viewing the entire page. This is especially helpful when reviewing a page.

Is there a way to take the course without sound?

Closed captioning is available for the hearing impaired and can be used to take the course without sound. While viewing the course, click on the "CC" button in the upper left-hand corner of the screen to bring up the closed caption window. You may then disable or turn down the sound on your computer.

Is there a text only version available?

Yes. A text-only version designed primarily for use with assistive technologies is available. See the Section 508 Accessibility page for more information. Links to the text only versions of the lessons appear at the end of the lesson descriptions on the "Start the Course" page.

Known Issues:

Netscape Navigator 4.7-4.8 Window Resize: Resizing a NN window with one of the course's pages displayed will likely result in an off-center, scrambled display. Use your browser's "Reload" button to restart the lesson and then use the LESSON MENU to navigate back to the page you were last on. This is a known bug in NN.

Flash Movies: Flash movies require a relatively fast CPU to play smoothly. Users of low-end machines may experience some sound break-up or flickering during animated sequences. Try closing all programs other than your browser for better performance.
