Dunno about exciting, but I just downloaded the latest operating system yesterday on the 296, ver 4.2, and then down loaded a fresh database... Upon restart the box cheerfully announced that it has NO terrain database to be found... hmmm, durned gremlins... Called Garmin, the tech allowed as how he had never heard of that one... We downloaded a fresh $150 terrain database on Garmin's nickle and all is well in Mudville tonight... Ya gotta be careful when you depend upon boxes that run on magic smoke... If the magic leaks out on a dark and stormy night you are in trouble... denny |

Or in IMC.... on our trip back from Michigan I needed to shoot the GPS 3
into STE, so I loaded it up in the KLN94 and thought I'd follow along on my FlightPrep system on my laptop. So I switched from the XM weather page to the approach plate but was still too far out for the little magic airplane to appear on the plate. Ok, switch back to the XM weather just to make sure we'd be on the north side of the approaching thunderstorms, yep, plenty of room to get around them... switch back to the approach plate..... You guessed it.... crash... darn Microsoft... so I had to put the toys away, get serious, and fly the approach "for real". So, until the plates come in an affordable panel mount system, there will always be paper in my airplane. Jim "Denny" wrote in message oups.com...

Though I'm not Windows fan, I believe that Avidyne and others use Windows as the foundation for their avionics systems. However, they strip out all of the junk that normally accumulates on a PC and are left with a fairly stable (and hardened) system. I suspect that you could approach that level of reliability if you did the same--stripped the system of everything but the FlightPrep, WxWorx, etc. But then, that would remove most of the non-aviation utility from the system.

It has been a poorly kept secret over the years that the Avidyne systems run a stripped-down version of Windows. I believe the same is true for the MX20, though I'm not sure how much for the MX20 Garmin retained in the new GMX200. JKG |

It had to be when they went from simply a situational awareness display to a PFD. No way is any certified PFD going to be running any form of windows - you simply can't meet DO-178B Level B or Level A objectives with windows. It's not proof, but look at avidyne's job openings. The sw jobs want RTOS and DO-178B experience/knowledge. Zip about windows. It has been a poorly kept secret over the years that the Avidyne systems run a stripped-down version of Windows. Hardly a secret. What is proprietary is how they got that first box with windows certified (Level C) in the first place. -- Bob Noel Looking for a sig the lawyers will hate |

The sw jobs want RTOS and DO-178B experience/knowledge. Zip about windows. You're right, it's not proof. The standards you reference are standards, not operating systems. I'm not an operating system expert, but I don't see why the Windows kernel couldn't be modified as required to meet whatever standards were necessary. Companies who have these type of requirements likely have extensive access to the source code and/or have access to the appropriate resources at Microsoft. So I don't think it's as impossible as you contend. It has been a poorly kept secret over the years that the Avidyne systems run a stripped-down version of Windows. Hardly a secret. What is proprietary is how they got that first box with windows certified (Level C) in the first place. I guess that's why I said "poorly kept secret." I don't remember Avidyne or Apollo advertising that their system used Windows, even though it was fairly obvious that was the case. JKG |

So I don't think it's as impossible as you contend. I'm not an OS expert either, but I considerable experience with the relevant certification requirements. Windows, like pretty much any COTS OS, would require so much modification that it would cease to be windows. And I doubt that microsoft would expose themselves to the potential liability.

I don't remember Avidyne or Apollo advertising that their system used Windows, even though it was fairly obvious that was the case. iirc, Avidyne did. In any case, the people at Avidyne that I've meet were open about it being windows-based. They wouldn't say how they achieved compliance with 178B Level C objectives however. -- Bob Noel Looking for a sig the lawyers will hate |
