    Weight loss when upgrading Avionics. Hard Data.

    No, the GTN-750 has internal cooling fans and the other equipment doesn't need forced cooling.

    A take on a recent thread - landed at 15 airports without refueling

    You're based out of Pine Mountain Lake? I've always wanted to go check out the lake, but I can't figure out the last mile from the airport. Is there any way to have a $100 burger or get to the lake out of there for someone not based? Also, congrats on the feat! I must try it someday. This area...

    Inop Oil Temp Gauge question

    The FSDO can offer an exception in the form of a ferry permit. If you need to move the plane to get it fixed, that's the option. Other than that, no, I don't believe so.

    Has anyone installed the Garmin GPS 175 yet?

    Wouldn't there need to be budget for a NAV/GPS switch, too? I don't see anywhere on that panel to put a third indicator. I guess the other option would be to just lose the second NAV.

    Engineer's take on the 737 MAX design

    I understand the concern. The earliest info is often just plain wrong. The stuff that follows is more accurate, but generally incomplete. Only with careful investigation and consideration does the most complete story come out. We each have different ways of getting there. For me, this iteration...

    Engineer's take on the 737 MAX design

    I almost certainly have confirmation bias on this one. I noted it in a previous post, #31: "Confirmation bias is definitely possible." Beating back confirmation bias is generally done by debating the points. Attacking the author only gets folks circling the wagons in two camps. If you're in the...

    Engineer's take on the 737 MAX design

    So, yeah, the open shirt and sunglasses shot is a bit douchey. And he's been management for as long as he's willing to list in his experience section. Wonder if I look douchey on my profile. Let me know. I can't string him up for the lack of a degree. At the time, they were still rare in com...

    Engineer's take on the 737 MAX design

    Prone to failure or otherwise, it's a single point of failure in a life-critical system. What MTBF would you find acceptable in such a device? It's the same argument I have with the word "safe". Safe just means inside a risk tolerance. Prone to failure means too failure prone for this...

    Engineer's take on the 737 MAX design

    It think it's this guy: https://www.linkedin.com/in/gregorytravis/ Not certain though...you know enough to verify that? EDIT: Nevermind! Verified it myself. https://www.linkedin.com/feed/update/urn:li:activity:6524764870888480768

    Engineer's take on the 737 MAX design

    If you're an engineer, why the doubt? The arguments made around the software seem especially sound.

    Do you have a link to his LinkedIn profile, by chance?

    Engineer's take on the 737 MAX design

    Just re-read your post and it didn't imply it as strongly as my first impression took it to be. I should cross-referenced my impression against what you actually wrote before I responded. Apologies. So, I'll be more specific in my inquiry: Which sweeping generalization or leap did you find in...

    Engineer's take on the 737 MAX design

    Agree. But the response was from someone claiming to be savvier than the author, which I suppose I should have been more explicit about. The author is absolutely qualified on the subject of software systems. As am I, with 27 years of experience, including 13 years of experience on...

    Ad hominem. Not really a valid argument.

    Engineer's take on the 737 MAX design

    I tend to agree with you there, but I believe there was a nuance in the criticism of the software in aircraft. Granted I'm guessing at the author's intent, but I believe he was mostly criticizing the certification of the software, not the actual use of software. Note that he doesn't denigrate...

    Engineer's take on the 737 MAX design

    I agree, this is surprisingly well written, especially to a lay audience. To your comment, I'll note Airbus aircraft have behaved without physical feedback for decades. Whether your prefer Boeing or Airbus, the stats say they're both very safe designs philosophies when done right. The thing...

    NOAA's Flight Path Tool

    Unlikely that there's an issue with this particular app. Perhaps I should explain better what JNLP is. Java Network Launch Protocol is a format that allows an application written in the Java language to be started right from a web page. That's what's in the file above. First it says where the...

    NOAA's Flight Path Tool

    Heh...I got it running! Wasn't that challenging. Download and install the Java Runtime. http://java.com and follow the instructions. Grab all the right files. https://bcaws.aviationweather.gov/java/fpt and grab each .jar file and stick them in a directory. Open a command prompt window and...
