jbs007 Posted December 16, 2015 Report Posted December 16, 2015 I am upgrading the panel on my '66 M20E and need to know about required instruments. I have looked up the M20 TCDS and CAR 3 regs and can't find info on if Vacuum, Volts, and Amps are required. I will have them displayed no matter what, but it will change how I have them displayed. Also, if anyone has done a EI CGR-30P and has a 3 blade Hartzell prop, how did you color your RPM indications? I get 2700 is redline, 2350-2700 is green, but does the 1950-2350 have to be a certain color? I'd like to make it yellow if I can. Thanks!
tony Posted December 16, 2015 Report Posted December 16, 2015 I installed an MVP-50 and have a three bladed prop as well. I believe I had them color it just as you described. Red over 2700, yellow for the 1950-2350, and green (I think I have white) for everything else. The numbers came off of the STC and flight manual supplement. Your old RPM indicator should have been modified somehow to show the limitation. As far as the minimum required instruments, that's a good question. The MVP-50 is considered primary and I removed all the old gages so if my MVP-50 malfunctions, I am just assuming its required because everything is on there now. I assume you are installing the CGR-30P with an STC, did you see if its noted in there?
rbridges Posted December 16, 2015 Report Posted December 16, 2015 In my '65, the vacuum only requires an annunciator for "low vacuum" IIRC.
jbs007 Posted December 17, 2015 Author Report Posted December 17, 2015 Thanks to both! Anyone know if volts and/or amps are required?
N601RX Posted December 17, 2015 Report Posted December 17, 2015 In addition to the Regs and type cert the other thing that can make it required equipment is that it has a listed limit in the limitations section for your manual.
Bob_Belville Posted December 17, 2015 Report Posted December 17, 2015 Have you something like this? Pages 3, 4. http://williams.best.vwh.net/m20e/mooneyafm.pdf
jbs007 Posted December 17, 2015 Author Report Posted December 17, 2015 Thanks Bob. That answers the vacuum question for sure. It doesn't mention volts or amps and I'd really like to get a definite yes or no on that if I can. Where did you get a digital version of that? Your N is pretty close to mine too (9357M).
tony Posted December 17, 2015 Report Posted December 17, 2015 In my opinion, a volt meter or ammeter are not listed in the required equipment section (page 4) of Bob's POH, so I would say the answer is its not required. Nor is the low vacuum indicator. Why would you think that is required? Unless I'm reading this wrong but the required instruments starts on page 4. What's on page 3 is not required equipment.

I agree about the voltmeter and ammeter. Out of curiosity, I glanced at the FAR/AIM and didn't see it listed, and it doesn't seem to be listed in the flight manual for the plane. The low vacuum annunciator is required b/c it's listed in the manual.

I went through this when I installed my JPI 900 and the discussion revolved around the ammeter. The ammeter is not listed in my POH as required equipment and my mechanic felt fine setting up the ammeter per the ranges on the non-required gauge. The key is what Bob provided below. It is what is in your particular POH that counts. The MEL was developed I believe much later than the 1960s. Sent from my iPad using Tapatalk

I Googled "M20E owners manual". Ms. Google knows everything. I assume you're referring to 9249M my first '66E. It is serial 1198 and is now based in KY. (I sold it in 1988.) My current '66E, N943RW, is serial 929 but the tail # has been changed a couple of times, the last time by Ron Westbrook whose wife was born in Sept. 1943. It began life as N2566W.
carusoam Posted December 17, 2015 Report Posted December 17, 2015 POH in modernish machines gives required equipment by day VFR , night VFR, day IFR, night IFR. Tomatoflames would be the basic FAA version of required equipment. Common sense and available cash fills out the rest of the list including airbags, seat belts and fire extinguishers. My tail number is only one digit different than JBS's. Let me know if I missed something, I did not look it up this time. Best regards, -a-
FloridaMan Posted January 2, 2016 Report Posted January 2, 2016 That is one reason I went with the EDM-900 instead of the EI 30P. The fuel gauges were certified in the EDM-900 and there was a $400-500 off special.
