By ICAO Annex 6, all airliners must have a certain number and kind of lighting installed and operating at night. These are your basic position lights, nav lights/strobes, and wingtip lights. Some airlines put additional lighting on their aircraft for other reasons, but not all. For example, the logo lights the article refers to are options on most aircraft, and some airlines do not have them installed - AA for example. Logo light operation, by the way, is often controlled by marketing preference rather than by regulation. Thus, while the Chronicle says there is not a standard for lighting, there is in fact a standard, and all airlines follow it. However, the standards for lighting may not be sufficient to specifically identify aircraft type and identity, as the article points out. I have no opinion on whether the airlines or other operators should be compelled by regulation to install additional lighting beyond the standard. I'm sure the ATC people know what they would like to see. ed >>>> Ed Hahn | firstname.lastname@example.org | (703) 883-5988 <<<< The above statement is the opinion of the author.
