    Got plenty of 46L, but nothing in a regular.

    Not sure where that came from, but always zoom-bag or flight suit.

    Blended wing ACs are coming !

    Sorry... I know I should focus on the very narrow issue of airframe, avionics, and powerplant, but after 25 years of engineering systems/big-picture stuff for the NAS, it's habit to focus on the things that actually determine economic viability. Virtue signaling? I think not. More the case...

    Blended wing ACs are coming !

    The vast majority of regional jet traffic occurs between high and mid density air carrier airports and a limited number of smaller air carrier airports. Air carrier traffic into smaller local fields is often not economically viable for a number of reasons beyond lack of ‘green’ or more...

    Blended wing ACs are coming !

    Don't forget the Spanloader, etc. At least 70 years of failed concepts. Net Zero is the latest rationale for accepting the limitations and infrastructure overhaul necessary... and absent getting those 2.8B people in India and China signed up for the plan, likely to be just as successful. After...

    fuselage welding

    I have to think there is some sort of society of welding gas bottle collectors that know all about the proof test stamps and history/interesting anecdotes of the inspectors. "Ah... yes. That one is a '17 by H. Hildegard... very rare... highly collectable. Apparently young Hildegard lasted...

    fuselage welding

    Amazing how bad welds can be and still be strong enough to work for a long time. Sounds like elevator somehow went full deflection and aircraft above maneuvering stressed things a bit too much.

    fuselage welding

    Fascinating stuff re: choices on welding with other than TIG and OA, as well as leaving stuff out the designer wanted left in... From the 2022 Bearhawk LSA accident... freshly released NTSB report. The pilot built the airplane from plans, and its primary fuselage structure was made of tubular...

    Report: Boeing 'Put Wall Street First, Safety Second', Creating 'Yearslong Decline of Safety Standards'

    At some point, Boeing and Airbus moved into the 'Bet Your Company!' bonus rounds on new platforms, resulting in a choice between risky innovation and lower risk stability. Once that seemingly guaranteed, low-risk stream of income (stability) grabs hold, and certainly aided by the deep trough...

    Anti-ice for experimental.

    We got almost nothing out of Mercury/Gemini/Apollo directly, outside of a few rocks... ROI was so bad we decided to shelve things for 50 years hoping that we could figure out a non-military business case for the Moon/space beyond Earth. The spinoff tech, though, was something else... likely no...

    Anti-ice for experimental.

    Time and continued capital availability for AAMs may produce a solution which is not $20K just for the hardware and 10 years of someone's life for integration, test, etc. While I am not hopeful we see the heavens darkened by eVTOLs any time soon, all that capital burned up by both legitimate...

    Anti-ice for experimental.

    Most of us older, grayer heads with copious experience hauling frozen water around handle flight into known icing as follows: prep the crew for flight with anti-icing fluid from an alcohol-based system (no weeping allowed... we ARE guys after all), then observe the usual bottle to throttle rule...

    remote controlled circuit breakers: ?what options exist

    Keep in mind that relays are often used to control higher power devices or circuits, so the switch controls - but does not actually make or break - that circuit under load. If the relay fails closed, e-juice is still flowing, and we end up using the CB as a switch. DAMHIKT. Also note there...

    remote controlled circuit breakers: ?what options exist

    Just wrapping up an initial implementation of a GPS jamming and spoofing CONOPS at a CORE 30 airport. We have a slide in the deck with a very pithy quote which summarizes both our problem statement for the effort and much of what the FAA, airframers, avionics folks, and operators have been/will...

    remote controlled circuit breakers: ?what options exist

    I suspect that Bill's constraints are not intended to keep us from having a meaningful discussion on the topic, or ignoring thousands of hours of flight experience in aircraft which all have the same sort of basic failure modes (no engine noises, no sparky stuff, no go-juice delivered, etc)...

    remote controlled circuit breakers: ?what options exist

    Your task, Mr. Zeitlin, if you decide to accept it, is to redesign the electrical systems of every active aircraft in the NAS/worldwide flyable fleet/known universe (extra points for the SETI thing). Until then, I suspect we'll be stuck with the somewhat flawed systems that have generated the...

    remote controlled circuit breakers: ?what options exist

    Maybe we start with trying to keep the doors on the aircraft and work up from there? ;)

    remote controlled circuit breakers: ?what options exist

    Big fun… besides a nose box chip, sparky stuff was an attention-getter. Was nice to have an FE on the ramp panel… especially with max’d out tanks in the cabin. Prob a bigger issue with the old non-crashworthy system. Once again, I’m struck by the level of misunderstanding re: working an EP...

    remote controlled circuit breakers: ?what options exist

    About 7K hours in a fair number of different fixed/rotary wing aircraft. Switch failures? A few - only one serious... one governor control switch in a UH-1H that got my undivided attention and the need for the seat extractor tool and a flight surgeon/proctologist after landing. Given we...
