Watching this closely!! Keep us up to date on the progress. Thanks
Thanks for watching and I’ll have another one out soon.
Very interesting project!
Thanks for watching and yes is another interesting piece of information. I rather doubt that it will make my landings any better however at the moment it is a novelty.
Very cool project, yes it would be cool to know the air gap under those wheels as a flare does not always present well in ground effect and dumping the flaps inches from the ground would be a smoother landing with less float in a long wing lightning. By the way supper nice Lance!
thanks for the feedback on the video, landing heith and the Lancair.
Very cool!!
Thanks for watching
Thanks for posting
No problem!
@@gaFlights can you check your email. I had a question for you.
I just sent you an email response. sorry for the delay
Any plans to implement on the IV-P? Aware of Stadia; has interesting aural output. Good luck
I might put in the IV-P after I get it refined a bit more. For me the IV-P is easier to flare and land smoothly than the Lancair 360. I've considered headset announcements of key above runway heights.
Nice. since it's a photon time of flight device it should have pretty hefty update rate. Garmin spec says 200Hz or better over I2C so that should be plenty for human use. 10Hz might be good enough but I suspect that more like 50Hz will make the measurement seem very live and reliable. Lag free.
Are you pondering making an autoland feature?
Dan - you are always impressive on your research. And yes not a true auto land but a "call the ball" type of landing assist. If we had indicated air speed (not ground speed), and several other measures I should be able to display a "ball" within a "ball" for "best" landing flare to a smooth landing would need to include something for throttle movement as well. This could be step 1 of an auto land system - however I'm not really wanting to take it that far. I'd be happy with a "landing flare assist" HUD. Garmin has an Autoland system available for planes with auto throttles. In emergencies it handles radio communications and other complex things as well. Like, finding best airport, runway and some compensation for crosswinds. I just trying for some experimentation.
@@gaFlights Thank you :)
For a proper smooth landing we might need the wheels to spool up as well to match runway speed. Air might also be too unstable for a rigid plane to set down perfectly every time. It might need actuated landing gear to match vertical speed perfectly. We might be bobbing like open sea. Maybe very fast flaps could do it as well.
The wheels spinning are interesting. Potentially some form of cups on the sides of the tires or rims that could scoop the air creating rotation. Flaps have potential. Some jet allow their flaps to deploy to 90 degrees rapidly for airbrakes.
Just found this project and I loved it. Are you planning on selling/open source the project? I would love to try it on my experimental aircraft. Congrats!
Thanks for watching the video and I don't have plans on selling it. It is easy to build and I could send you a copy of the parts list and source code if you want to try it. I used it a lot at first then the novelty wore off. Anytime I have someone flying with me it is a big hit for a discussion.
@@gaFlights Not sure if you got my first reply. If possible, send me the parts list and source code. I am not a "hardware" guy but I will do my best to follow.
@@alxsouza send me your email address and I'll send you the parts list.
@@gaFlights I have sent you an email message. Thank you!
I replied to your email with the source code and parts list. Good luck and keep me posted.
