I think shock cooling has to do with the rate of coolng and the starting temperature of the cylinders. It's more of an issue if the starting cht is high and the rate of cooling ( °/min ) is high. Lycoming recommends to not exceed 50° F /min. If the cht's are not allowed to get too high then the impact of cooling rate is not as high. If cht's are allowed to get high then the rate of cooling has a bigger impact. A cylinder starting at say 450°F and cooled to say 340° at > 50°/min is shocked cooled. If that cylinder starts at 400°F and is cooled to 340° the rate has a much lower impact because the temp delta is much lower. If that makes sense.

Here's a stupid question: I have always wondered how many cycles does it take to flush out and freshen up the oil inside the oil cavity in the prop? I think about this every time I cycle the prop on run up! I cycle the prop usually three times and staying within 300 RPM.

I don't feel he should be forced to roll back and wait indefinitely without compensation. Your BT example is still irrelevent. This fiasco is the result of a lack of compatibility and guidance on the part of Avidyne. The Avidyne equipment is not working just fine in his airplane. Again I'll refer you back to the three parties involved. Avidyne sold the equipment and got paid well. The shop installed it and is going through the hassle of troubleshooting. To the best of my knowledge they are paid by Avidyne. What Avidyne is doing is damage control and cutting their losses. It is better for them to pay the shop rather than refund the customer. The major looser here unfortunately is the trusting customer. He paid the big bucks and is sitting on the ground with his airplane. Not only should Avidyne pay him but if he chooses to return their equipment for a refund they should also pay the shop to install whatever he chooses to replace it. What happened to the Avidyne entegra? Thinning, hopefully you are able to come to terms with this fiasco and you're satisfied with your decision. It's very easy for others to have opinions when on the outside looking in.

1. Roll back to which software combinations? Avidyne doesn't know! 2. So the customer is the one who should wait around? This is exactly what it means to hold the customer hostage! You would have another customer with a grounded plane wait for Avidyne to hopefully get their act together! Would you be willing to do that? Your bt reference is irrelevent. Here's an idea: if the customer does agree to wait around how about Avidyne show some consideration and pay them to wait? Say 1K$ per day? After all they are a valued customer right? Or if they're not willing to pay take the units back refund the customer and life goes on. I would respect your opinion if, instead of saying that's the way it is and the customer has to just shut up and wait, you said that's the way it is when mixing in different manufacturers as in a high end G500 panel for example. It really is best to stay within one vendor if they offer an intergrated solution. At the present time it happens to be Garmin. In the future it may very well be Avidyne or someone else. But right now Avidyne should not bite more than it can chew and stick to being a GNS alternative in a simple panel. I'm not knocking Avidyne and I'm glad you're happy.

You have a tendency to talk out of both sides of your mouth. If, as you say, this is just the way it is and the price we pay for progress then why do you need to blame anyone? Why do you need to blame the shop? After all it's just the way it is right?! Reason is I suspect that's not the way it is! The way it is as I see it is you have three parties here: Avidyne who is the manufacturer of both the hardware and software, the install shop and the customer who pays them both. As in any arrangement there has to be a win for all parties involved. In this particular case it's a win, lose and double lose. Avidyne wins because they sold the customer a bill of goods that doesn't work but received top dollar for it. And according to you they did nothing wrong. Because that's the way it is! The shop loses having to go through the hassles of troubleshooting something that was doomed to fail before Avidyne even released it. The poor customer is the double loser because he paid the big bucks and has to ground his plane! Now of course according to you Avidyne had no responsibility because they walk on water and of course you can't blame the poor customer! How could you! So you crucify the shop! Even though that's the way it is you got to blame somebody! Only problem is you fail to see that Avidyne is holding both the customer and the shop hostage! Yes I know...that's the way it is!

It is incumbent on Avidyne to provide clear guidance. They failed miserably. It is Avidyne who didn't do their job. What the shops need to do is drop Avidyne like a hot potato! Refuse to install and recommend against their hardware unless Avidyne provides them with clear guidance and guarantees of compatibilities.

Oliver, he and others wants to crucify the shop who is working diligently to troubleshoot and help the customer! The shop who, without any guidance from Avidyne, is doing the troubleshooting that Avidyne was supposed to do! The same Avidyne who is holding on to your and othets' money while your plane is grounded! What the shops need to do is drop them. Refuse to install their hardware unless Avidyne provides guidance and guarantees of compatibilities.

And of course Avidyne makes false statements like "...we have customers out there with the G500/600 who have a later than 6.21 software and the Release 10.2 with no issues..." Which is incorrect as evidenced by yet another customer account... "...I have bought a Avidyne IFD440/540 combo and Garmin G500 in November 2017. Therefore my G500 have Vers. 7.12 at delivery!!! In the installation Manual at this Date is nothing written about the G500 Software Version!! For me it is frustrating cause I have spend a lot of money, and now I have a lot of problems with the IFD..." Do you still insist on giving them a free pass and continue to blame the shop??

Maybe Avidyne, aspiring to drive a G500 panel, would be checking and monitoring Garmin for any updates. They had no idea when the G500 update was released! ... it's "possible" it came out during that time... Simpson. So, yes, you're right, it seems they are sitting around looking at a crystal ball when they should be proactively monitoring Garmin! And of you're going to talk about the shop earning their keep, how about Avidyne earning their keep? They are holding on to about 20K$ per installation and the airplanes are grounded! Have you reconsidered blaming the shop?

There you go again!

I wish you wouldn't resort to personal attacks unless you can't help it. Try to focus and keep civil if you can. Why are you so fast in blaming the shop? Did Avidyne inform the shop about the lack of version compatibility testing?

Please get your facts straight because what you say is not correct. Simpson is confused and so are you. It's totally understandable to be confused but he represents the company and he should get his facts straight. Go back and read again. Avidyne dropped the ball by not warning customers that they hadn't tested for compatibility. What do they do instead when the issues surface? They play dumb! But on a broader note, this illustrates the real nature of this beast with mixing manufacturers. It's a major and chronic issue Avidyne customers will be facing. What happens going forward? Unless Avidyne develops an intergrated solution of their own to compete with G they will never go beyond just replacing the GNS. And who suffers? The good old customer!

You left out a few details perhaps because they are inconvenient to your argument: The G500 update was released way before the Avidyne update. Therefore they should have tested it. At the very least they should've warned their customers if it was not tested for compatibility. Not play dumb and say they didn't know of the G500 update release. That's just irresponsible and disrespectful to their customer. I agree with you there are good people working at both companies. They are just more competent at Garmin. And you can pick up the phone and speak to a field engineer at Garmin and they will help you. They will even thank you for calling! Imagine that! The best thing Avidyne can do right now to hopefully control the damage is refund the customers with grounded airplanes.

First he blamed Garmin and that didn't work. Now he blames the satellites?! In the mean time Avidyne is holding on to these poor folks' money while their plane is grounded! But they are working on it! Who are you going to blame next Simpson!? The Russians?!

No worries Oliver...take a number! Avidyne is working on their issues! All of them!

If we assume the mineral spirits help valves from sticking wouldn't Avblend be a better choice than MMO?

Look at it this way: you will spend quality hangar time and become intimate with your queen! There are "annuals" and there are annuals! But at this point that's irrelevant. You could have taken it to a msc. You decided to buy it saving some money.

I found my mistake. Garmin is showing transmit power while King gives power consumption. Apples and oranges!

Anthony, I'm comparing (I think!) power consumption. Amp draw which peaks while transmitting. Garmin shows 10W transmit which translates to 0.7 amps. King does not show watts but shows draw while transmitting to be 8.5 amps, which calculates to 119W! So the 165 draws 12 times as much?! http://www.bendixking.com/Products/Navigation-Communication/Navigation-Communication/KX-165 https://buy.garmin.com/en-US/US/p/67886#specs I thought it's a typographical error on King site. But their new nstall manual shows same thing!

I got the figures from the respective websites. I expected them to be similar. Certainly didn't expect the KX165 consumption to be 14 times that of the GTN! I just want to be sure I'm reading it correctly. https://buy.garmin.com/en-US/US/p/67886#specs http://www.bendixking.com/Products/Navigation-Communication/Navigation-Communication/KX-165

I was doing an electrical load analysis of my 14V system and came across something strange. My GTN750 puts out 10 Watts min transmit power. This calculates to 0.7 amp draw when transmitting. My KX165 otoh transmit specs list 8.5 amps which calculates to 119 Watts! 10W vs. 119W! Am I missing something?

Copyright notice is in the photo. Ethically oriented people will respect it. If they really want it they'll inquire.

Only if you behave from now until then!

Anyone can copy anything they want and do so everyday. But the overwhelming majority does care and take the time to extend the courtesy of asking. Since I had my airplane painted there have been several folks who have asked me if it'd be ok for them to utilize my scheme. Some even have asked me if I'd provide the files for the paint shop. This is the first time someone just arrogantly stole it. I'm actually flattered that it's so appealing and popular! Tough job to be a leader but somebody has got to do it!

Yes, there is a problem with that. That scheme concept is mine. I paid Scheme Designers to digitize it so the shop can accurately render it on my airplane. Being fully aware and proceeding to copy it anyway is grossly unethical. You made a mistake to not even attempt to ask for permission. You can tell a lot about someone's character by how they handle mistakes they make.
