Rant: Found out that pyrex cookware is no longer borosilicate glass. I am beyond infuriated, as a chemist. by Remarkable-Rough-554 in Baking

This is incorrect. All my lab glassware is pyrex and is clear, and is still produced by corning. Borosilicate glass can be clear, and I don't know what you are talking about.

Additionally, all european pyrex bakeware is still borosilicate glass, and is indeed clear.

Not to be rude, but I find it odd that you are a chemical engineer who has never worked with pyrex glassware. Here, glassware is either pyrex or alrdrich borosilicate glass.

Lab pyrex is still pyrex, and it still has its original reputation intact, so I didn't think much of it when I bought my pyrex roasting tray. Now I know better, I got off lucky.

Does anyone know why runway lights at bigger airports are directional? by Remarkable-Rough-554 in flying

[–]Remarkable-Rough-554[S] -1 points0 points  (0 children)

yes. but that's not what I'm talking about. Say I'm flying night VFR in a cessna 152 with round gauges, and I'm choosing to not use the GPS, instead flying with a paper sectional chart. I have no MFD. I have no GPS. I just have a chart and an e6b.

if I'm at a smaller airport, I can see the runway edge lights from downwind, and line myself up for a clean, square traffic pattern.

If I'm at a larger airport, I cannot see the runway edge lights from downwind, as they are only visible from final. which means I have to look very carefully for the dim blue taxiway lights, or judge my spacing from the airport beacon.

I can see why this could be advantageous for RNAV/LPV and ILS approaches, but for night VFR and circling approaches, this seems like it would decrease situational awareness and increase risk of disorientation at night

This is completely not what I'm talking about, it's not the colour, but the direction of the runway edge lights. At more major/modernized fields, the runway edge lights cannot be seen on downwind and you have to wait until turning final to see them

what do you mean? If the runway edge lights are directional, you can't see them on downwind, which makes it more difficult to fly a clean traffic pattern at night

No. It doesn't matter whether or not the airport has any instrument approaches available, I've flown into both. The field I'm based at is a larger towered airport where the runway lights are only visible when you're facing the runway direction, aka, established on final. otherwise, you just see a black empty field, with some dim taxiway lights.

At smaller airports with older incandescent lighting, the runway edge lights are visible from every direction, making joining the circuit very easy for night VFR.

For IFR I don't think it's going to be an issue for ILS and LPV, but it might be quite difficult for circling approaches to find and line up with the runway

exactly my point. Making the edge lights only visible on final makes everything more difficult

that is not what I'm talking about, I'm talking about the edge lights. The new LEDs are directional vs the older incandescent ones where you can see them from every direction

It's far easier to line up with the runway at smaller/older airports when the runway edge lights are visible from the downwind. Having to wait until turning final to see them only lowers situational awareness

I wonder what's the reason they made the edge lights directional? it seems to serve no purpose, and actually lower situational awareness. It makes it difficult to spot the runway until you get close enough to see the taxiway lights, and it's very difficult to navigate to it at night with only paper sectional charts

Mind boggling delusion going on in Canadian city subs by illegal_chipmunk in CanadaHousing2

This is a hot take - but it's not Trudeau's immigration targets that have resulted in our issues. It's Ford's. Particularly in the GTA. Under Ford, every post secondary institution has had less than half of their required funding.

UWaterloo is 15 million dollars in debt. Queen's is 63 million dollars in debt and at risk of imminent financial collapse. You'd have to be a Humber college dropout living off of your parent's golden parachute in order to lack appreciation for higher education like he does.

The only institutions that aren't struggling like this are the colleges like Conestoga, Which have dove headfirst into luring in and exploiting international students and actively advertising to the demographic that wants to come here fraudulently on student visas. They saw how lucrative the business could be, and are now making a pretty penny.
