Kris Rockwell of US Airways wrote this SVG application, "Airbus A321 Exterior Lighting Systems Freeplay," as a simulation of aircraft cockpit lighting controls and as a proof of concept for using a Smart Graphic for pilot training applications. A Smart Graphic is a single graphic file designed to be reconfigurable during runtime so that it may replace scores of static images. SVG is ideal for creating Smart Graphics.
Adobe® Illustrator® was used to create two SVG graphics: the aircraft (right side, A321top.svg) and the switches in the control panel (upper left, A321Panel.svg). Note that the image of the panel (lower left) is a static GIF file and is not interactive.
The trainee clicks on the two-position and three-position switches in the control panel to turn the aircraft lights on and off. (Clicking the switches invokes JavaScript functions that set the display property for several SVG elements.) The aircraft illumination is actually the crafty use of gradients with ordinary path elements to provide the appearance of fading spotlights.
