    Cessna Citation - Montebello, VA - 4 Jun 23

    Well, that turned political pretty quickly:

    Oshkosh 2023

    One factor is the travel time to my brother's house in Arden Hills by car. Anoka is 9 minutes while Crystal is 17 minutes. Downtown St. Paul airport is 15 minutes.

    Oshkosh 2023

    It is the same amount of time as my last visit. I'll meet up with two brothers and a college buddy of my oldest brother in Arden hills, MN and we drive to Oshkosh starting early on Tuesday (get in shortly before noon) and drive back on Thursday morning. We stay at Ripon College. Previously I...

    I Must Have Bad Taste in Pictures

    You have different tastes, not bad tastes.

    I Wonder if Quinn the Eskimo Ever Got There

    The wikipedia page doesn't say (https://en.wikipedia.org/wiki/Quinn_the_Eskimo_(Mighty_Quinn)) but I see now it has been covered by a lot of musicians. Haven't heard it in years.

    But the power requirements go up as the cube of the speed

    That is pretty much it. When just plowing through a fluid (no lift) and you want to double the speed you can either use 8 times more power or cut the drag in half. It is typically better to know ways to reduce drag than ways to increase power density, so years ago I spent $75 on a copy of...

    The Latitude Nut

    My guess is that it would be set to some intermediate latitude like 45° or perhaps a bit south of that to minimize the drift for most areas of the U.S. At about 14 minutes into this video the latitude nut is discussed. The whole video is informative about other interesting details on the...

    The Latitude Nut

    Went up to do some pattern work and to check the drift or precession of the club plane's Heading Indicator (HI). After engine start I set the HI to the magnetic compass value, It was about ten minutes later that I was at the end of the runway ready to take off. The HI differed from the compass...

    Walt Disney 1944 presentation on 100 Octane aviation fuel

    "Octane numbers are a scale for rating the power gasoline will deliver." That's a Mickey Mouse explanation.

    No 12V start cart at KFFZ any longer

    The clock in the club Aerobat is inop. While figuring how to get the plane legal for IFR I looked into replacements and found this: http://www.fdatasystems.com/gt-50/ Typical price is about $174: https://www.aircraftspruce.com/catalog/inpages/flightdatafc50.php According to their FAQ: Will the...

    Tapping on the altimeter

    Or stick a wad of gum on the outside edge of a prop? Just kidding too! I'm pretty sure I've seen hesitant altimeters before, mostly during climbs after takeoff when I'm looking at it more frequently to see when I've reached a specific altitude such as 300 ft below pattern altitude. Just did a...

    Tapping on the altimeter

    I started my flight training in gliders and one thing I picked up was it helped to tap on the altimeter. Otherwise the needle may sometimes move in jumps as friction seems to make movement a bit sticky. Never did that in a powered airplane because the engine adds sufficient vibration to keep...

    Is This Greeting Card in Bad Taste?

    I'd be good with that. Actually I would have been Ok with the original wording. I'm not humble but when I took my check ride I already had in mind a possible outcome of "Well at least I still get to fly." Because under most scenarios the student still gets to fly, even solo, after a failed check...

    Mosul Orb, and other unidentified aerial phenomenon

    A shadow does quickly diffuse because the sun isn't a point source. So a small object at altitude can have effectively no visible shadow. So that is a possible reason it wasn't visible, so I only described my observation and did not draw any conclusion. The orb's light/dark reflection not...

    Mosul Orb, and other unidentified aerial phenomenon

    In the overhead shots where it is clearly sunny because things on the ground are casting shadows, where is the shadow of the orb? I ran them at quarter speed and would have at least expected to see a hint of a shadow of the orb in the 11 to 13 second period of the first video. At about the 17...

    Starship Flight Test Poll

    Hmmm. Looks like it was a ground control ordered rapid disassembly when stage separation didn't happen as planned. Even with five engines out their ground control chatter continued to report nominal operation on the remaining engines. Speculating: perhaps because a loss of some engines means...
