polcat Posted November 14, 2009 Share Posted November 14, 2009 Last night prior to starting, my FE noticed that the #3 LSGI buttom had a light bulb in it and when jiggled, the button would light up. Anyone know why the LSGI buttons were lit? Nothing in the Dash 1 explains this. Quote Link to comment Share on other sites More sharing options...

Nothing in the Dash 1 explains this. the bulbs were taken out because all they did was burn ya and if you couldn't tell you were in LSGI w/o out a light you were in deep trouble Quote Link to comment Share on other sites More sharing options...
Plaprad Posted November 15, 2009 Share Posted November 15, 2009 In ten years I think I've seen two planes with the LSGI lights working. Was told early on about them, but the first time I saw them light up blew my mind. All my planes we used them for spare bulb holders since the assemblies never worked.

DC10FE Posted November 15, 2009 Share Posted November 15, 2009 I was told many, many moons ago that the lights were deactivated because they would melt the green buttons of they were illuminated for too long. Like Plaprad said -- they were convenient spare bulb holders. Don R. Quote Link to comment Share on other sites More sharing options...
Zaherk Posted November 16, 2009 Share Posted November 16, 2009 Controlled by switch in the valve housing which are set to open between 15°-17° blade angle. Lights must be illuminated when the throttles are between approximately 1 inch below flight idle and maximum reverse. The lights must be extinguished above flight idle. On our civilian birds we use them all the time. We always back it up with our torque gauges especially when coming over the gate after landing. Trust me, those green buttons haven't melt yet, at least not in the last 20 years that I've been around our Herc's. Quote Link to comment Share on other sites More sharing options...
SEFEGeorge Posted November 16, 2009 Share Posted November 16, 2009 Those use to be part of a trivia question: how many light bulbs on the flight desk aren't working, except for the spare bulb box. Or something along those lines. Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted November 16, 2009 Share Posted November 16, 2009 A couple of our MC-P's came off the initial SOFI mod line with working NVG compatible LSGI buttons. They were kinda cool until the pulled the bulbs. 217 had em and I think a couple of the next in line as well. Dan Quote Link to comment Share on other sites More sharing options...

Zaherk Posted November 17, 2009 Share Posted November 17, 2009 Ronc and Jake, True I'm was thinking of the Beta Lights. Never heard of LSGI lights, that's new to me. Thought that was what polcat ment, calling the Beta lights LSGI lights. Quote Link to comment Share on other sites More sharing options...
USMCFE Posted December 3, 2009 Share Posted December 3, 2009 Well, the same holds true, if you need a light to tell you you broke low pitch stop you're in the wrong line of work. Quote Link to comment Share on other sites More sharing options...
DC10FE Posted December 3, 2009 Share Posted December 3, 2009 I'm pretty sure BETA lights, along with the anti-ice and low oil pressure lights, were required by the FAA for commercial certification. Don R. Quote Link to comment Share on other sites More sharing options...

Yeah, except for those pilots that the "pause before bringing them over the gate" exists solely in their minds LOL I always used to think to myself when that happened "well we will find out soon enough"!
