    Oh the horror!

    I am sort of happy to hear that it isn't just me...

    And the award for “Most in need of new N number” goes to…

    I have reserved N144SX for a planned RV14 build; my wife claims that she will not set foot in a plane with that N number (and we are both very stubborn).

    Autonomous Car Problems

    My thoughts had always turned to the fun I could have messing with the autonomous cars: chaff canisters on the motorcycle/handfuls of glitter in a car tossed out the window should stop the cars behind police like hand signals should stop oncoming traffic if you happen to want to cross the...

    What's the point of the G5 GPS?

    This is the extended Kalman filter's role - every time I try and understand it, I feel like I understand it less... but it works. Also, if you have a multi-receiver GPS you can (more or less) directly measure attitude (3 receivers required, with 3 separate antennas). What has always kind of...

    $10,000 to get off Delta flight

    If it is a XXX flight, they will probably get plenty of volunteers without having to pay big $! Some people might even pay to be on that one...

    Any recommendations for Michigan or Ohio?

    There is always Traverse City, though we kind of liked Frankfort when we were there last week as well.

    This Showed Up on Hagerty Drivers Club

    The remainder of the hangars were replaced with new buildings a couple of years ago (new buildings are much nicer, but I miss the history of the hangars), and there were still parts of the runways up until the last re-configuration of the tracks (~2006). My office happens to be within the...

    Taxiway closed by notam due to snow/ice

    There are a few things wrong with this article:1) ABS absolutely works on ice (at least modern/recent ABS software) 2)ABS on snow might or might not be better than a skilled driver - it will depend on the surface condition, tire, driver, and the ABS software/calibration. About the only time...

    Taxiway closed by notam due to snow/ice

    The theoretical reason that they lock and unlock: if they don't occasionally unlock brakes your reference velocity drifts away from the actual speed over the ground (relying on integrating longitudinal acceleration while the vehicle may be changing it's pitch attitude), and if the reference...

    Time for a NASA ASRS report to cover your a$$?

    Taxiway closed by notam due to snow/ice

    I got to spend ~4 years between IMSA DP, IMSA GTLM, and WEC GTE Pro - those guys are good (and a couple are ex F1) and the teams would have used ABS had it been legal hands down, no questions asked. All it takes is one little flat spot from a momentary lockup and it can ruin an entire race...

    Taxiway closed by notam due to snow/ice

    I might have some experience here: my day job is tuning ESC, ABS, TCS, and rollover stability control. We use metrics like ABS efficiency (think mean deviation from optimal slip %) as pass/fail criteria on snow, ice, and dry pavement - and do instrumented tests of stopping distance with vs...

    Where to retire?

    My wife is a teacher, I am a fan of keeping property values high, and also think that investing (more) in public education is the right thing to do for the next generation - so I always vote for more school funding when it come up on a ballot. Other than my post above, this is done without...

    Where to retire?

    Admittedly taken out of context, but it always rubs me the wrong way when a parent complains about paying for both public school (via taxes) and private school for their children. Those of us who have chosen to not have children are still subsidizing your rugrats public education whether you...

    Fraudulant insurance claims denied would I still have to report?

    Excuse to send the FAA a photo of your nether region?!?!

    [NA]Anti-seize on lugnuts?

    Having dealt with this a lot at work, it seems like it is usually brought on by someone using either a worn out/oversized socket and/or only getting the socket partially onto the lugnut before pulling the trigger on the impact gun. Usually, I find the best way to deal with them is to hammer the...

    Is truck inventory going to get any better?

    You can always order the spec you want as long as you are willing to wait for it. ( we are almost 7 months into the wait for the Bronco that we ordered) Of course, that make me think of the 'world's oldest profession' scene in Idiocracy:
