    Collaboration?

    One of the professors I know (and asked to help before his department told him that he could not) commented that he was very surprised to learn about my disability. It's not something I exactly mention to most people. It has always been a sore spot for me ever since my second grade teacher...

    Is wearing a personal chute with a bail-out system acceptably safe compared to an airframe chute?

    Well aware. I was simply pointing out that the landing gear not the only attenuating mechanism and honestly, as someone (RiggerRob?) pointed out, they are effectively a secondary mechanism due to the normal nose low attitude associated with ground contact.

    Collaboration?

    The funny thing is my wife is an attorney and would have been the one handling the review of any waiver on my end....talk about a very defensible document in court should something happen. But whatever....it is what is it.

    Collaboration?

    I mentioned that idea to one of the local engineering departments and they declined as they perceived the potential liability (with or without the waivers I suggested) as being too great.

    Collaboration?

    Despite being an EAA member myself, I have had zero luck with getting hold of anyone at the local chapters for any reason. The FBO manager I talked to at one of the local airports said that the two he is aware of within driving distance are not "active" to use his description.

    Collaboration?

    I think I asked this once before but the project was shelved before it went anywhere due to other things coming up on my end that took precedence. I am getting to a point where I have more free time to get back to working on a design but the same issue creeps up. Those of you who have spoken...

    Is wearing a personal chute with a bail-out system acceptably safe compared to an airframe chute?

    The landing gear is only part of the way the Cirrus manages those impact forces. Admittedly, the Cirrus models have a lot of room for improvement but is still better at managing vertical impact loads than about 95% of GA aircraft. The seats have an energy absorbing module for example. It's...

    Shoulder Belts on a Baby Ace

    Noted. I was just thinking about reducing the tendency of the "point" to dig in rather than the transmission of the load into the rest of the frame. I looked at that and just thought of it as akin to the point on a Danforth anchor when it contacts mud or other soft soil.

    Is wearing a personal chute with a bail-out system acceptably safe compared to an airframe chute?

    Those of you who know me, know that I am an advocate of being prepared for any contingency but even I have to say: the odds of that are pretty minimal. I can count the number of fatal in-flight fires I am aware in general aviation aircraft of on both hands. Aside from the weight issue, there...

    Shoulder Belts on a Baby Ace

    As a side note, I would go with a "roll bar" type cross tube that is flatter on top rather than the 'A' shape in the drawing. Think of it as an inverted 'U'. That provides a bit more area for the forces to be spread out if/when the aircraft flips over. It's less likely to dig in and thus...

    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.

    Landing gear loads?

    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...
