flysolow Posted January 22, 2023 Report Share Posted January 22, 2023 Good morning Mooney Space! I've seen a few other topics that had died out without concreate answers on the removal of the annunciator panel found in Mooney instrument panels. My question is, can the factory annunciator panel be removed when installing modern avionics such as a Garmin G500 TXi with EIS? Does this deviate from how the aircraft was originally certified? Current annunciations: Gear Down, Gear Unsafe, Left Fuel, Right Fuel, Speed Brake, Alt Air, Prop Deice, Pitot Heat, HI/LO Vav, Alt Volts, Start Power, STBY Vac, Trim Fail, Emerg Bus, Boost Pump. The Garmin G500 TXi with EIS and the GFC 500 autopilot will replace most of these. I am pretty sure of the answer, I just figured I would ask to ask! Lastly, without clouding the original question, has anyone replaced the annunciator bulbs with LED bulbs (annunciator, not post lights)? If so, how do they dim and do they affect any other systems?

LANCECASPER Posted January 22, 2023 Report Share Posted January 22, 2023 Or you can just move it over to the left panel above the TXi and make it more noticeable to the pilot. 1 Quote Link to comment Share on other sites More sharing options...

Thanks Lance, that is the plan. We’ve heard different things so we figured we’d get some input. Quote Link to comment Share on other sites More sharing options...
toto Posted January 22, 2023 Report Share Posted January 22, 2023 I was kind of excited about this for a while, but it appears to have been discontinued. http://www.approachaviation.com/html_pages/flexalert.html It’s disappointing to have a fully modern panel with a primary annunciator that’s frozen in time.

hais Posted January 22, 2023 Report Share Posted January 22, 2023 For those lights you need to keep, you might be able to swap out the annunciator with a 1 row version. It is however currently out of stock - check with LASAR. Quote Link to comment Share on other sites More sharing options...
flysolow Posted January 22, 2023 Author Report Share Posted January 22, 2023 Thank you all! Keep them coming. It is a shame a company has not made replacement annunciator panels for all aircraft. I’ve worked with this company, but it has been a pain to get things approved. https://aerosafetysystems.com Quote Link to comment Share on other sites More sharing options...
ArtVandelay Posted January 22, 2023 Report Share Posted January 22, 2023 Sure:I removed the vacuum system.JPI replaces fuel and voltage annunciations.Gear annunciations replaced by simple lights.Ram air was removed, so no ram air annunciation.So nothing left for the annunciator to do.Edit: your version has extra annunciations, they might be replaced by simple lights, with possible exception of “trim failed”. If you replace autopilot with GFC500, it will have it’s own annunciation on G5/GFX. Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted January 22, 2023 Report Share Posted January 22, 2023 Look in the TCDS. If the annunciator panel is not mentioned, you should be OK. It still amazes me that we are not allowed to modify our planes in any way without STC approval, except for our panels. 1 Quote Link to comment Share on other sites More sharing options...

One question: Did your glare shield have the bump and, if yes, how was it removed, and who did it. I guess that's three questions. Quote Link to comment Share on other sites More sharing options...

201Mooniac Posted January 23, 2023 Report Share Posted January 23, 2023 On my last upgrade the only annunciator left was the gear so I removed the annunciator panel and replaced the gear annunciators with an Eaton style annunciator with a push to test. I checked the TCDS and there was no mention of the annunciator panel that I could find so the shop agreed it was legal to remove. Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 24, 2023 Report Share Posted January 24, 2023 Check the MEL in the POH… limitations section. IFR,VFR,DAY,NIGHT…. I don’t see an annunciator panel… but, many of the lights are called out individually…. PP thoughts only, not a mechanic… Best regards, -a- Quote Link to comment Share on other sites More sharing options...
