    Will taxiing help engine in airplane sitting idle

    Lycoming has a service letter on that subject: https://www.lycoming.com/sites/default/files/attachments/Engine%2520Preservation%2520for%2520Active%2520and%2520Stored%2520Aircraft.pdf They say: "Engine temperature and length of operating time are very important in controlling rust and corrosion...

    PA25-235 Pawnee - San Pedro, Sinaloa, Mexico - 2 Sep 23

    Possibly a structural problem? The left wing appeared to be folding up and back well before the angle of attack got unreasonably steep. Once the wing started twisting back it appeared to force plane to pitch up steeply. I've seen those ag planes at work and they seem to fly similar climbs at...

    Inop flap indicator

    Appreciate the clarifications re MEL. I think my original question was answered with the considered opinion "So per the 213(d) guidance I would determine it does not constitute a hazard and placard it INOP with a corresponding log entry. And given it requires no maintenance a pilot could...

    Inop flap indicator

    The Cessna 150 was type certificated under CAR rules so a minimum equipment list would not likely exist (and I have searched.)

    Inop flap indicator

    Their argument rests on flaps being secondary control surfaces rather than "instruments and equipment". And that seems reasonable since the article dealt only with the actual flaps. But in this scenario the flaps work, only the flap position indicator is inop. The flap position indicator itself...

    Inop flap indicator

    The flap indicator on our C-150 is inop, though the flaps themselves work fine. What little secondary info I could find suggests that an inop indicator makes the plane un-airworthy, while ironically if the flaps themselves were inop a simple placarding would maintain the plane's airworthiness...

    Dan Gryder has $1M judgement against him.

    Never watched his videos, but from what I heard second-hand he often invented things. Yet he had some sort of non-trivial following on Youtube.

    The rate of near misses and the effective cost of a collision.

    Looks like about 36% of airplane owners wont shell out a few thousand: From: What a difference ADS-B In makes—or does it? That article links to FAA current ADS-B equipage stats: Current Equipage Levels As of July 1, 2023 One local data point: The local flight school has two airplanes, only one...

    The rate of near misses and the effective cost of a collision.

    There are vastly more birds than drones - but that argument was first made years ago and didn't affect the FAA's thinking at all. I haven't read a Nall Report in years, but I recall in many years that midair collisions were so few in number that they were lumped in with miscellaneous causes...

    Wikipedia science articles

    That reminds me of a 9 year old Weird Al Yankovic video I only just discovered this last month. Guess I'm falling behind on contemporary culture.

    Wikipedia science articles

    This guy captures my own observations of some of the science and technical articles in Wikipedia. It hasn't become unusable, yet, but caveat lector is essential.

    More passenger mis-behavior

    Probably for the same reason they did nothing to help the mother and daughter - either didn't care or piss poor decision making. The guy who eventually exchanged seats with the daughter reminds me of a flight I took several years ago. I was flying alone for work in an aisle seat on the left...

    Why requiring medical certificates may not improve aviation safety

    Since the EAA and AOPA have been backing it and the FAA has applied several years of effort into it, I'm guessing some variation of it has a better than even chance of being approved. Allegedly it is a consequence of the "FAA Reauthorization Act of 2018". Possibly under "Subtitle B--Aircraft...

    Why requiring medical certificates may not improve aviation safety

    It looks like that the proposed regulation changes in MOSAIC would pretty much eliminate the need for medicals for most of the flying done by pilots. A sport licensed pilot, having only a driver's license and self-certifying with respect to medical fitness, would be able to fly most common...

    Oppenheimer

    Three weeks ago my wife and I visited northern New Mexico. We visited Taos, Santa Fe, and Los Alamos. In the latter we visited several Manhattan Project sites and related museums. There I learned that a Hollywood movie called Oppenheimer would be coming out soon. Didn't pay much attention...

    MOSAIC (Modernization of Special Airworthiness Certificates) NPRM Released

    After reviewing the NPRM and giving it some thought, I don't think these changes will accomplish anything useful beyond letting sport pilots fly legacy airplanes like Cessna 172s and its competitors. The proposed rules don't seem to have any impact on the cost of new aircraft either. That's...

    MOSAIC (Modernization of Special Airworthiness Certificates) NPRM Released

    Story here: https://bydanjohnson.com/mosaic-news-faa-running-ahead-of-schedule-unbelievable-proof-here-now/ It's a big deal! Edit to add that according to the copy of the NPRM on Dan Johnson's web site the actual NPRM will be published by the FAA on July 24 - during Oshkosh. The FAA will no...

    Why requiring medical certificates may not improve aviation safety

    I believe this PDF is the entirety of the 1926 regs: https://ia800904.us.archive.org/12/items/1926USDeptOfCommerceAirCommerceRegulations/1926%20-%20US%20Dept%20of%20Commerce%20-%20Air%20Commerce%20Regulations%20.pdf

    Why requiring medical certificates may not improve aviation safety

    Medical requirements appear in the 1927 regs (see pages 29 and on): Air Commerce Regulations Effective December 31, 1926 But those regs appear to have been developed from the Air Commerce Act of 1926. As far as I can tell, prior to that act civil aeronautics was self-regulated. Edit to add that...

    Flaming Gorge and mountains south of Jackson Wyoming

    Nice photos! However, even without struts the wings get into the pictures. I think you need a plane that doesn't have those things. ;)
