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…

True. And for some reason they always want to put the kitchen printer right under the heat lamps.

Not only are you mastering the art of flight training on a vintage plane, but you’re also moonlighting as a creative tech guru with your Nav log printer project.

Your kneeboard “cargo pants of the air” are legit, and turning the cockpit’s windshield pillar into prime real estate for receipt prints? Genius move.

Your journey from regex to JSON wizardry is like a flight plan through the tech skies.

Keep soaring, my friend!

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

I remember this being discussed on HN before. It felt a bit like "till receipts are killing us" which in the context of someone flying a 40 year old plane with noted defects might not be a primary concern.

I wanted to buy a thermal printer myself but couldn't find a definitive answer or evidence of the BPA part being a risk. I got one that uses BPS instead - other papers also raised concerns about this, but again I couldn't find direct evidence of health issues associated with the handling of till receipts.

I decided as the receipt printer will be used infrequently and I have been handling till receipts for the last 4 decades I wouldn't worry about it. BPA is also present in food cans and plastic bottles - the link you sent states the concentrations are higher in receipts - but at the same time I don't intend on eating the receipts or rubbing them into my skin.

Generally I'm quite cautious about chemicals in everyday life, I try and reduce the amount in our house using natural products for cleaning for example.

At the same time we're constantly surrounded by toxins so I often find myself having to do this sort of rationalisation to avoid worrying about seemingly everything all the time.

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,…

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).

How do you prepare? And what is the issue? Aerodynamics?

You still have to fill it up by touching and breathing in the fumes while pumping it into the tank, so not exactly, but you're right that it does affect others as well.

I realize this is an anecdote, not data, but after flying my own plane for 5 years and getting >500 hours of flight time, plus soldering off and on for 30 years with leaded solder, my lead levels were fine at my last physical. I don’t drink avgas or anything, but don’t take precautions other than attempting to avoid getting it on bare skin.

We got one of them fancy lads what drinks the jet A, boys. Thinks the 100LL ain’t good enough, no doubt!

It's hard to find NDB approaches at all anymore. Did you do IR in the US? The FAA from what I've read doesn't even encourage an instrument checkride in IMC. That's crazy you did it twice.

It can vary greatly across the country. My instructor loved to use LORAN which one of the planes was equipped with (and was shut down shortly afterwards).

damn -- if I went through the silly PDF that SkyVector provides -- why not! Lemme research a bit what the export format is!

Not sure about Europe, but I think Foreflight is the most popular EFB in the US for GA pilots. Would be sweet to have support for it!

SkyDemon is the equivalent in Europe. At least for VFR pilots.
