I'm a dinosaur and I'm always amazed at the technology that pilot's have available to them these days. While complex to learn, having huge glass navigation systems sitting in front of you in a single engine plane seems so foreign to me. I did my instrument ride in a C-172 and my commercial in a PA-44. During both of those checkrides, I ended up having to shoot ILS approaches to minimums, in turbulent IFR conditions,…

Honestly - as someone who did their primary and instrument using steam gauges, and now mostly flies a Cirrus Perspective+ system (G1000 with some extra's), you'll get up to speed in less than a few hours of digging through the manual and playing in the SIM.

After about 10 or so hours, you'll start finding so many small things that make life infinitely easier for single-pilot ops that it's ridiculous we can do x or y with so little effort.

Running lean of peak, having a TOD, programming in our steps, hitting the approach button and just letting the plane fly is black magic at times. There's no going back for me at this rate, especially when I just want to go places. I've got a single-seat Yak for when I truly want to "fly"!

I actually just bought one from the business next door but on eBay I've seen them at $20 (tho if you get the Super Pro XL Mega 4K one it's more hehe)

>I've seen them at $20 Have another look, its more like 50 nowadays, thanks to the new ones having proprietary paper with chip.

damn you may be right (maybe something between 20 and 50 at least)

does second hand count? gumtree m/craigslist/facebook marketplace/ etc etc

I've worked in a bunch of restaurants and now work with restaurant software (we're hiring some cool positions if you are interested [1]) The one thing I'd be a bit wary about here is heat making that paper unreadable. I've seen a bunch of kitchens intend to run thermal printers in kitchens, but had to switch to impact printers because how quickly the paper would turn dark in the ambient heat in the kitchen, plus the…

Also, most thermal paper is high in BPA/BPS. https://www.pca.state.mn.us/business-with-us/bpa-and-bps-in-...

General Aviation still uses lead in their gas, despite it being shown several times in enormous nationwide studies consistently to not be necessary, and often simply requires more cost in maintenance (lead builds up on spark plugs causing a lot of issues).

So environmental impact isn't high on their list already, and this BPA issue is very likely going to be completely ignored by anyone in that field.

G1000s are great, but it's disappointing that just about everything else has remained basically unchanged on GA aircraft for the last 30+ years. I hope that we will see some actual innovation in GA engines, airframes, and fuels soon. Fuels might be the most promising for the near-term.

The innovation/future exists, but is not evenly distributed. For example Diamond planes [1] have: - The same G1000 (NXi) - A composite body - Jet-fuel burning engines adapted from recent Mercedes diesels - Computer control of that engine through one knob instead of managing the throttle/mixture/prop separately like cavemen - Crash testing, like impact absorbing seat structure and separately enclosed fuel tank modules…

Half a year ago I asked around about the price of a DA62 I’m Brazil and it would be in the range of 1.6M USD (8M BRL).

Did the price you quote (600k USD) was for the single engine model? If so, how much would a DA62 cost you in the US?

Yes, but the avgas lead situation is primarily a problem for the people behind/under the aircraft, not inside the aircraft.

Worth reading this Brother study on thermal paper degradation: https://www.anixter.com/content/dam/Suppliers/Brother/White%...

Worth looking at Figure 3 showing how different samples of thermal paper have vastly difference reactions to high temperatures.

Once had a set of Aliexpress plastic water carriers take 6 months to arrive to me during COVID and it when it arrived, it seemed like the plasticizers from the carriers (or the factory?) severely degraded the thermal shipping label.

You should look into a roll chart. It’s a small device typically mounted to a handlebar of a motorcycle that contains directions. As you reach each waypoint, you turn a knob and roll the next waypoint into the window. It should work just great with your receipt printer and your not limited to the length of the A pillar in your plane.

I've ridden a motorbike for 15 years and this is the first I've heard of roll charts! Prior to phones, I would just scrawl my notes onto a sheet of A5 and tape it to the top of the tank. It didn't work well when it was raining.

It's most common in the dual sport community. I ride dual sport rides here on the west coast that still provide roll charts as their primary routing.

Same! My checkride was in 2001 in a 1979 Cessna 150. My check pilot was a 5'2" WWII vet that needed a booster seat and was notorious for opening his damn door on final approach (which he did to me, luckily I was prepared).

> notorious for opening his damn door on final approach

Isn't that a good strategy for when someone thinks they'll be in a crash so it doesn't jam closed? Congrats on passing despite that!
