    How did you develop engineering intuition and grow into a strong problem solver?

    I was exposed to airplanes in the USMC, my first carrier was as a licensed airplane mechanic (since maybe 1978), went back and got a BSEE in mid 90s, got pilot license and instrument rating in subsequent years, bought a small airplane. I do airline support work now, all our group does is handle...

    Air India 787 crashes on take off

    Given how recent the event and how modern and complicated the aircraft I can't imagine anyone even bothering to comment. Depending on how the operator has it set up there is no doubt a ton of data to review in addition to a long list of standard forensic verifications that need to be made on the...

    American Airlines plane diverted because it was too big for the airport

    I've personally gone to the local airport for a practice night flight only to find the runway closed because a little earlier someone landed their one month old million dollar TBM-900 with the gear up. In this case there was only one runway. A lot of airports have a mix of short and long...

    Design Phase Product Integration Management- A new GA Aircraft

    I'm not a structures person. Looking over the thread it strikes me that this is a question about the requirements phase of a project. The Navy used to train requirement verification and validation as an early step. Once you know the requirements and their relative priorities, you can develop...

    American Airlines plane diverted because it was too big for the airport

    If some event at the intended destination closed the one suitable runway they might handle it that way.

    Current Standards for Circuit Card Rework and Repair of Airline Avionics.

    WK, Cockpit light plate repair is not complex. Typically, there isn't enough profit to support a large repair base for minor parts used on small fleets of old aircraft. Regulations for approved parts on certificated airplanes still exist though. Support gets thinner when supporting a fleet of...

    Design Phase Product Integration Management- A new GA Aircraft

    You might start looking over the data from The General Aviation Manufacturers Association (GAMA). https://gama.aero/

    Current Standards for Circuit Card Rework and Repair of Airline Avionics.

    Twenty something years ago, the shops I was supporting at an airline wire using IPC 610 standards for circuit card repair and rework. I've been away from that level of repair since. Anyone know what current industry standards might be? I'm trying to develop approved line repairs that could...

    Avionics Workshop Training Manual

    I think the original question in this thread needs to be a bit more specific. What area of aviation are we talking about, for example, military, civilian, general aviation, transport category, aircraft wiring, back shop repair of components like flight management computers and engine...

    If improperly done....What are we including with this statement on the major-minor determination?

    When I was in A&P school, back in the late 70's, and we talked about airworthiness the instructors told us that the FAA had never defined it. The word airworthiness has always been used in the recommended log sign off for an annual though. Over the years I kept an eye out for a definition and...

    Avionic- GPS NAV solution

    I believe the flying club I'm in has 2 Cessna 172s equipped with single GNS650s and they are fully IFR capable. Why would you need 2 GPS sources? In any case, also try the Avionics forum in Pilots of America.com. No doubt somebody has already addressed what it is you are trying to do. My...

    William (Bill) Anders

    There are no age limits for the pilots license but you do need to be able to get a medical. There are Class 1 2 & 3 medicals depending on the type of operations you fly. Now there is also basic med option which I would guess is roughly equivalent to a Class 3. My posts reflect my personal...

    MIL Qualified Product Listings

    I've watched how a lot of the MIL specs I was familiar with become SAE specs. It's good someone is maintaining them. Has anything come along to serve the role of the Qualified Product Listings the military used to produce? My posts reflect my personal views and are not in any way endorsed or...

    AC43.13-1B Figure 10-17

    This material has been around for a very long time. For the typical 43-13 user it's already core knowledge. The FAA also has a downloadable 115 page Weight & Balance Handbook (FAA-H-8083-1.pdf)too. Every licensed aircraft mechanic is trained on this and probably tested in written, oral and...

    Seeing Through Hot Metal

    One of my coworkers told me that when he was a younger guy he was assigned to a work detail to build up a couple J58 engines for the SR 71 program. He said, he was told back then that you could see the turbine through the engine case when it ran in the test cell and that he was amazed when he...

    Looking for Paralleling Generator General Training and Tester Resources

    I work in an airline Engineering Support Group that supports the aircraft maintenance division. One of our chronic problems involves troubleshooting the electrical system on older 3 engine aircraft. When an aircraft has an odd number of engine driven generators or just a lot of them (as in...

    Major Alteration or STC ?

    I don't think it makes sense to take a one size fits all approach to aviation. Theres the physics, theres the operating environment technical and business wise. The processes are probably different because when you do something to one airplane operated for a specific purpose in a specific well...

    ATA chapter/subchapter partnumbering

    I don't have any recent first hand experience with this. In the 80's when I was an airline technical writer, we used to talk about ATA spec 100. I think today its going to be IAW with something like iSpec 2200. -> https://publications.airlines.org/CommerceProductDetail.aspx?Product=313 My...

    Blade Helix definition?

    I don't know how it's described in drafting terms but with airplane propellers a 36" pitch is how far the propeller would travel forward in one full revolution in an incompressible fluid. I believe this factors in the twist of the blade which I assume keeps the aerodynamic load on the blade...
