    Preparing to build a TBD

    Into and out of Class C? This isn't Old Mudsuck International in the 1950s. Let's not discourage people from basic safety equipment that allows one to see and, more importantly, be seen by other traffic.

    Preparing to build a TBD

    Glad I am not the only one disappointed to learn that he isn't.

    Landing gear loads?

    If anyone needs anything more out of the Pazmany landing gear book, let me know, I have the forum's reference copy. Sorry for the delay in replying...we have been swamped at work the past few months.

    If anyone needs something specific out of it, let me know. I have a copy.

    Tube construction: Alternatives to conventional welding

    Two things: 1) That's my point in asking "show me a practical example". 2) There's a reason why they aren't. Either you end up with a heavier structure to account for the downsides of the material in question (or the limits of the designer's knowledge) or you have to have so much volume (or...

    Not quite so structural foams?

    We got some that way (more than we ever needed or asked for) by telling a company that we could use the “scratch and dent” stuff to teach CAP cadets about composites. I will ask our aerospace education officer who we got it from. Technically, I am the one who got it donated (the joke is that I...

    Tube construction: Alternatives to conventional welding

    For something designed and built by a layperson, they should be considered the best option. They are the F1/IndyCar of homebuilt cockpit structural integrity. Why do you think I not using aluminum on composite in my design’s cockpit frame? In theory or with the use of advanced alloys by...

    Text Messaging Approach & Departure Procedures

    It’s funny because the only GA“radio guy” I know of who was responsible for a midair is the crusty idiot who was using a frequency list that was at least several years old. We know that was when the CTAF changed at the accident airport and he was heard making calls on the wrong frequency and...

    Text Messaging Approach & Departure Procedures

    One of the few reasons I miss living in Indianapolis is hearing the guy who would visit the airport I lived by at least a couple of times a week: “Battle Creek traffic, November....” Usually someone would politely remind him it’s EAGLE Creek. Once, having come through earlier in the day and...

    Text Messaging Approach & Departure Procedures

    Joining the 1980s would be a more accurate description since the readily available form of the tech has been around since at least that time. Then again, these are usually the same folks who will proudly describe multiple instances of partial or complete loss of power due to carb icing...

    Tube construction: Alternatives to conventional welding

    The point he was making though is not that there are alternatives but whether a need actually exists for one. Back in the 1920s and 1930s when what is today called aerospace welding was still being developed (read as: quality control issues and/or issues with design of safety critical welded...

    Text Messaging Approach & Departure Procedures

    It probably will eventually become a thing for GA at busier airports (although at 99.9% of airports, simply making people use the VHF radio already in their plane would be more than sufficient) but then again, our chunk of aviation still has a conniption fit every time anyone suggests that it...

    Don't Do Anything Dumb

    I used to teach EMS providers and other medical providers that the general rule in trauma and critical care was “Air goes in and out, blood goes round and round, the chest goes up and down. Any variation on one or more of these is a bad thing.”

    Lithium Iron Batteries

    No piece of an aircraft should be taken for granted.

    Lithium Iron Batteries

    No clue wet or dry. I talked to a guy who was two years behind me in high school and is an electrical engineer who specializes in aerospace systems. He pointed me to a manufacturer who has a system that handles all of the cycling etc you describe. I'm not just trying to cobble the battery...

    Lithium Iron Batteries

    True, but I plan to operate in cold weather because of the need to travel to Michigan frequently due to one of my volunteer engagements. Plus the LiFePO4 ones I saw (that did not have bad reviews regarding service life) would work out to be FAR heavier (especially once you factor in wiring...

    Lithium Iron Batteries

    I decided to go with NiCad since it ended was the lightest way I found to meet the Ah requirements (6.9 lbs for 81 amp hrs 24v; 4.53" L x 2.13" W x 8.82" H) and not have to worry about the in-flight fire risks associated with lithium batteries. They aren’t cheap (in fact, they probably cost more...

    Building more crash-worthy composite planes and cockpits

    Just wear the HANS during takeoffs and landings. That’s what I plan to do. Of course, I am designing my aircraft to have a place to stash my helmet and HANS. It might be less of an option if you have a really cramped cockpit. I’ve worn the newer ones and I didn’t think it limited my ability to...

    Sealant between aluminum

    It's still a valid comparison that you're not dealing with a "watertight" seal as you want to believe. How about you just accept that and we can move on?
