ARMv8.1?

Tell me about it: we've had much the same since EASA was let loose on us. Where formerly the annual inspection report was a single sheet checklist that got signed and stapled into the aircraft log book, now its a multi- page documentation package complete with a signed and sealed authorisation, issued by the owner, to carry out the inspection. In the 9 years since EASA take-on I've almost filled a box file with non-expiring documentation and, as a consequence, I now fully understand the old American joke about the documentation weight and new aircraft types.

and those with the engine-powered generators to run them ....

Good point. I'd guess bar in more recent types because metrication and because aircraft tyre pressures are often in bar, but I've never knowingly sat in the cockpit of anything with constant speed props.

The most complex cockpit I've ridden in was on one of those six seat Piper PA-32 Navaho variants. There were seven of us needing to ride and I got offered the right-hand seat. Fun. It had an auto-pilot but I don't remember anything about the engine management. Would it be usual to find constant speed props on a PA-31?

It seems likely that gliders will get some sort of exemption, along with older powered aircraft that don't have electrical systems. There's a lot of talk on r.a.s about what will count as the TABS-qualified position source. Current the best bet looks like being a Trig TT-21 or TT-22 transponder with the new TN-72 position source.

Same as NZ - ASI's read in knots and have zero at the bottom just like the UK and Europe.

Unsurprising: a nautical mile is 15% larger than a statute mile.

All sorted out for me when I discovered, in a US recipe, that a US cup of rice weighs 95g. If you have one of these new-fangled digital kitchen scales thats useful to know.

That certainly makes a sensible serving per person, but one of my UK teacups is only a little more than half full with that weight of rice in it.

I've never driven a car that showed litres per km: my oldish Focus lets me select MPG or litres/100 km but that's it. L/100km is probably the more useful way of showing fuel consumption if you're used to it, but the car's guestimate of miles or km left in the tank can be even more useful.

No but I'll bet it's BS - or at least in one.

It is.

I use large releasable cable ties, so the available cable length is just right and the rest (mostly) doesn't get in the way, or tangled.

Hatstand.

WRONG WRONG WRONG a pint is 20 floz (a US pint is 16 floz & a us floz is slightly larger than an imperial floz). I hate getting served a short measure every time I order a pint of beer in the USA!

The "Cup" for measurement was introduced by US cook Fanny Farmer, the actual capacity of the cup was never defined but the ratio between cups, jugs etc.. was. This enabled for easy scaling of recipes (simply use a bigger cup!). For purely convenience reasons the USA had defined the US Customary Cup but there is also the US Legal Cup (Christ they cant even keep to just one!) the Metric Cup & the Imperial Cup.

non of these can be called standards.

I do not know any without constant-speed propellers, and I have flown quite some.

There are 3 pairs of levers for the engines: throttles, propeller speed controls and mixture controls.

In more modern constructions (e.g. DA42NG), there are just power levers and the engine management handles the gory details.

Also the benefit for education.

there was no need to explain number bases to children as they progressed to higher mathematics as they were already familiar with the concept through their pocket money. 12 penny's to the shilling, 20 schillings to the pound & any 5 5 year old could happily work with it (even if they were lucky to get more than tuppence ha'penny for pocket money :-) ) (that said I don't want to go back to pre decimal coinage)

And the standard that wins out is not necessarily the technologically better standard. Betamax was better, technologically speaking, than VHS.

Sadly? You sure about that?

That's what the IEC C13/C14 plug and socket are for. Which UPSes use.

No, the holes are too small for a British Standard child finger to enter.

The shutters are to protect against the insertion of foreign items that may conduct & operate automatically. Blanking plugs are considered by many to be unnecessary & possibly dangerous this is why no Socket Covers have BS approval for use in BS

The above claim that the BS1363 skt. is the safest in the world is not just a mater of opinion it is a widely accepted fact.

Screwdrivers may not fit but there are any number of conductive items that will, it has also not been unheard of for users to remove the earth pin rendering the connected equipment potentially dangerous, it is impossible to insert any item into a uk socket without inserting an earth pin first.

In fact child saftey was one of the primary design considerations when the BS1363 Plug was developed.

The NZ plug was developed in 1937, the BS1363 plug in 1947.

There are regulations to cover when that is permitted. amongst other requirements the device must be "Double Insulated" meaning that even if a fault develops it is impossible for any part of the casing to become live).

I loved it, it was so quaint and esoteric. And then i looked forward to my first visit to England at the age of twelve -- and they had had the gall to go decimal shortly before. Oh, the disappointment. I still have and treasure some paperbacks that give the price in shillings and pence on their covers.

Yep - looking at my Dutch extension leads (Schuko) the sockets have shutters under circular holes that are way too small to poke a finger in anyway. I can't get the shutters to move out of the way unless they're both pushed in together - which is very hard to do except when pushing a plug in. The socket is a deep recess so that by the time the pins are in the holes they cannot be touched. Also a dropped plug tends to land on its side not pins up. All in all a fair match for the safety features of the UK plug.

More importantly the UK plug has one hideously dangerous design flaw! The top (which is the bit you hold onto to pull it out) is attached to the base by a single screw into a plastic thread, if this fails it will most likely do so as you are pulling the plug out leaving all the exposed wires and that live fuse sticking up just waiting to catch a finger as you hit the switch next to it. I've had this happen twice (and avoided touching anything live) the first time I froze in horror for several seconds. Schuko plugs have two sides rather than a top and bottom which means you are not trying to pull them apart every time you unplug them.
