Your experience sounds to me more like a hardware problem than software. For example, the continuous rebooting may be caused by an intermittent ground connection to the G1000, causing its power to switch on and off. Given that the panel was "hacked" by the same outfit that made the poorly kludged aux tank system (a system that clearly does have a major design flaw) and gave you the bogus operating instructions, I am far more suspicious of them than Garmin. The G1000 was only the most obvious indicator of a major problem somewhere in the aircraft. Most reboots are caused by software. If the power were being switched on and off, it would not be synchronized with the boot process. If it were me, I wouldn't do such an interview, as there is no conclusion about the real cause of the problems you experienced. To point the finger on the basis of pure speculation would leave you vulnerable. As can be seen from the discussion that this has generated, inuendo can go a long way toward creating a lasting negative impression that has no basis in fact -- yet. On the other hand, it's hard to be too cautious, and publicity has a way of giving the corporate world more of a conscience. -- Transpose mxsmanic and gmail to reach me by e-mail. |

And it's reasonable that a small metal shaving produced during the Garmin installation may have been dancing on a circuit board someplace. This is rather grasping at straws. The most obvious and common cause of multiple reboots is bad software design. -- Transpose mxsmanic and gmail to reach me by e-mail. |

Unless, of course, it was the power wiring. I suspect a momentary power interruption could reboot a G1000. It would not do so in synchronization with the software. -- Transpose mxsmanic and gmail to reach me by e-mail. |

If the power were being switched on and off, it would not be synchronized with the boot process. The avionics in the aircraft that I fly reboot when they are powered off then on. No synchronization required. Of course, in the sims that you "fly", software is the *only* thing that can cause a reboot, so it's understandable that you would arrive at that such an opinion. Neil |

What gives you the impression that there was some "synchronization with the software"? Nothing NW_Pilot reported would suggest it, and the frequency and number of reboots implies something completely different. Neil |

After this Issue I think that there should be manual back up gauges and instruments for the required equipment under FAR 91.205! If I were flying the kind of flying you are doing I'd invest in a 496. It would give you at lease some level of backup for almost everything in the plane except radio and engine instruments. I have a portable GPS that worked great! XM weather is almost useless out side the U.S. I was thinking more about the nav and GPS derived panel not the XM weather. |

John Theune writes: and as had been pointed out by a number of people, there is no solid evidence that make it clear that the reboots where caused by the out of range sensor. It doesn't matter what caused the reboots, because only defective software reboots in the first place. No a hardware problem could have also been the cause. An electrical short caused by the "hacked" wiring sounds like an excellent place to start looking. |

The computer in cockpit is not foolproof. I can tell that there is at
least one Citation X where the computer simply shut down one engine and left no trail of diagnostic data behnind, just empty memory. Obviously you don't normally expect that sort of behavior from a corporate jet... They landed with one engine (no pilot overide) and the Cessna engineers came out and did a lot of head scratching. I do not know what the final diagnosis was on that one. |

![]() If indeed you are knowledgeable about Garmin software internals, I appreciate your courage and your input on this topic. On 5 Oct 2006 17:57:21 -0700, "g1000_eng" wrote in . com: I won't delve into the actual debate issues of whether to go glass, realtime reliability vs. features demanded, benefits vs. risk of various situational awareness methods, or anything like that. Of course, the real issue is whether it's rational to rely on an electronic system with a failure mode that is capable of leaving the pilot with little else than three steam gages (AI, AS, Alt) and magnetic compass, and taking out all communications, navigation, engine instrumentation, and autopilot when it goes. Perhaps you can confirm the loss of autopilot functionality when the Garmin system goes off-line. If so, perhaps you can explain why the autopilot is incapable of switching to being driven by the steam-gage AI, and functioning as a wing leveler in that event. After all, if the pilot is able to use the autopilot to keep the aircraft right side up in the event of the Garmin system failure, he will be able to focus much more of his attention on diagnosing the cause of the failure. |

Go ahead and post. I can vouch for the credentials of at least 2 of the wingmen.. I'm tryin to figure out who #4 was... I was actually #4 in the Bonanza. We put the slowest plane first :-) Keiran Smart was in the Tiger. I'm not sure who was in the 170 though! I'd forgotten about Kieran.. and I MISS that tiger.. Just so nobody gets their underwear ruffled.. these guys regularly flew together in dissimilar types and were based out of the same field.. I've sat in on their briefings in the past. The other two.. we do know who they are.. but they both fly for a living and dont need the press... Anyways.. enough of hijacked threads Dave |
