Okay, it's been awhile since I've been in the 73 and I don't have the oil skins, but.... the block of annunciators on the glare shield panel (think there are 6 of them), the general ones that say hydraulics (or whatever) correspond to the light gray panels. At least that is my understanding in the -200. But I've been wrong before. Or was it that the light gray panels have immediate action items associated with them... ummm well you got me thinking now.... wonder which it is.
