5.12. VIEWING THE BEHIND-THE-SCENES FLIGHT MODEL 61<br />
Figure 5.6: Illustrating <strong>the</strong> forces acting on a Baron 58 [Full size →]<br />
by pressing Ctrl + M on <strong>the</strong> keyboard) and moving to an outside view (e.g., by pressing Shift +<br />
8 on <strong>the</strong> keyboard for <strong>the</strong> chase view), you can actually see all <strong>the</strong> forces calculated on each piece<br />
of <strong>the</strong> craft. With some wind and turbulence turned on in <strong>the</strong> Wea<strong>the</strong>r screen, you can even see<br />
<strong>the</strong> pseudo-random velocity vector flow field around <strong>the</strong> airplane. The velocity vectors seen are <strong>the</strong><br />
actual vectors interacting with <strong>the</strong> aircraft, and <strong>the</strong> force vectors (<strong>the</strong> green lines <strong>com</strong>ing off <strong>the</strong><br />
plane) are <strong>the</strong> actual forces acting on <strong>the</strong> plane—nothing is just for show here. This is <strong>the</strong> actual<br />
work that X-<strong>Plane</strong> is doing.<br />
The green bars extending from <strong>the</strong> control surfaces of <strong>the</strong> aircraft indicate how much lift each<br />
section of <strong>the</strong> surface is generating; longer bars represent greater force. The red bars, likewise,<br />
represent drag, and <strong>the</strong> yellow bars represent lift from vertical control surfaces.
