Waterjet cutting is the preferred method where parts being cut are susceptible to heat related issues. I'd have thought they would have used this process rather than laser cutting. Laser cutting can't cut some materials (metals are no problem) but it can also engrave parts it cuts which is an advantage for example cutting machine parts. Each part can be engraved with all the relevant material, part, batch Nos etc.

The statistics since the industrial revolution are irrefutable and the climate and weather changes are what science is telling us is happening over time. Deniers love th cherry pick individual events to prove their point. Every one is debunked.

Nuclear power stations are also extremely environmentally unfriendly to build, take up to 10 years and while operating costs are low once running, take many years to recoup the initial capital cost which is in the $billions. Australia has more sun than anywhere else on earth and it is free. Making the most of it is blindingly obvious. We have the most and fastest uptake of rooftop solar on earth so even the general public are beginning to understand

It is only the last 20% where charging slows and it is not linear. 90-100% is only worth it if you are heading off on a long trip. 40% of our energy is now coming from renewables during the day and this is increasing all the time. Eventually it will be 100%. We are in a transition phase and that will continue for some years but eventually all the fossil fuelled electricity generation will disappear. The poor public EV charging infrastucture in Australia is amost entirely due to the previous LNP governments head in the sand attitude. It is improving though and new charging stations are planned for the outback with the installation of a large battery charged by stand alone solar. The cost to set up is tiny compared to a fossil fuel service station that requires a lot of energy to operate and needs to have the fuel delivered hundreds or thousands of kilometres by huge fuel hungry tankers. NSW has a EV destination policy and is providing grants for installation of chargers. In 2022 EV sales were only 1.8% of all new cars sold. By the end of September the figure had more than quadrupled to 9% and is increasing. More EVs were sold by the end of May than in the whole of 2022. EVs are expensive but the entry level is now close to the cost of the same size ICE vehicle. I am off to Noosa next week, a 550km drive. I'll leave with 100% charge & have the choice of a quite a few chargers on the Pacific highway. Apps tell me if they are busy or not & I'll take a 30 minute break while the battery tops up at a fast charger. I'll get to Noosa in about the same time it took in my ICE car. My old car that I bought new was 12 years old with 225k on the clock so it was time for a replacement. My choice to go for an EV was based on my lifestyle of travel and a desire to be part of the solution rather than continue the problem.

Aerodromes can be vey lonely places. Sometime I go up to my hangar on a perfect day for flying. Get some fuel, preflight and takeoff for a great local flight. I hear little on the radio, sometimes just the odd person at a far away CTAF with a 10 mile or joining call & if I'm monitoring centre just one or two RPT or IFR calls. I make a 10 mile and joing call, land and put the plane away. I have lunch and do something around the hangar, then drive home without having spoken to anyone all day. Then on another day there are aircraft and pilots all over the place. Visiting aircraft come and go and the airwaves are full of chatter. That's just the way it is.

Well that brought all the dinosaurs out. Plenty of opinions but no evidence.

It doesn't have zero emissions though. Diesels are the worst emitters.

There are many manufactures working to produce viable elctrically powered aircraft with plenty at the prototype stage and hundreds of battery technologies under development. I just bought an electric car. It is fantastic. Instant torque power, no noise, no vibration, & more high tech functions than I can count. It will be old tech within a few years due to the massive increase in battery and electric motor technology and everything that surrounds that. 7 year unlimited warranty with CATL estimating 1 milliom kM before battery degradation will require a replacement. 1000 kM range and more is already here. Sodium is replacing lithium at 1/3 of the cost with the energy density now rivalling lithium. Internal combustion is on the way out and fossil fuels will run out in 30 years or so. I predict that many of the current electric propotype aircraft will be in full production in 5 to 6 years. Ignore it if you like but it is coming, like it or not.

You cannot get more energy than you use unless there is some other energy source like gravity or kinetic energy from the mass of the vehicle already in motion. Hybrids generate power to charge their battery but use the energy of the petrol engine to do this. There are huge advances in battery technologies happening right now though most that have huge energy density have problems with longevity. There are many companies working on the issues now. Eventually some of these technologies will enter production. Already sodium batteries are being put in to EVs in China & the cost is about 1/3rd of lithium and an Australian Lithium Sulphur battery promises 500% more energy than existing Lithium ion batteries at half the cost. There are many more.

The Pipistrel Electro Aero Alpha made quite a splash when it was introduced in 2019 in WA. From memory it has about an hour endurance and the battery can be swapped out in under 15 minutes. Good for initial training and circuits etc. They will have made quite a few improvements by now I'd say

Ah the secret of perpetual motion. I had a discussion about this with a bloke at the aero club & he couldn't accept that my electric car would not charge as it is being driven. I tried to explain regenerative braking but he thought that it should continue to charge as it was being driven as well. Even after some time the penny failed to drop.

Polycarbonate is the same. Mr Sheen is a furniture polish & works OK but it isn't anti static and doesn't last long.

The best window cleaners IMO are just a few drops of dishwashing liquid in warm water, applied with a soft cloth or sponge and squeegeed off well. No streaks or smears. Vuplex is good for anti static and cleaning acrylic, lexan & other plastics.

I am constantly amazed at many of these oddball one offs etc as to why they were actully built. Many are just butt ugly and that never leads to production and sales. It is that old saying that they only flew because they were so ugly the earth repelled them.

That is a pretty beefy looking front mounting plate. What does that weigh?

In this case that is not relevant anyway as the engine has fuel injection

I think you said this before Nev. A cup of petrol with the right oxygen mix is enough to blow your house up.

That doesn't fill me with confidence to fly in a SR20. It is like saying "If you can't land this aircraft you can't fly with me".

Towering CUs (if there were any) are extremely dangerous. Vertical winds of over 200 mph have been recorded in them. If one was entered inadvertently and at the airspeed of a Cirrus it would be at the core very quickly & at that point there is nothing that can be done if it is a powerful system. The system has control and structural failure the likely outcome.

Veryt sad. Grandfather and 3 grandchildren. Condolences to the family and friends. ADSB data shows a steady climb out with fluctuating speed indicating some turbulence. Based on the photos of impact scene I think it will be very difficult to determine the cause.

A WORLD FIRST!! That's an indication that CASA has been asleep at the wheel. UK pilots have been able to self declare since April 2016 for any GA aircraft up to 5700kg. Once up to the age of 70 & then once every 3 years after that with no upper age limit. UK CAP 1397.

I had to look up what a tight end is as it sounds very uncomfortable.

The term ultralight is not a recognised name anymore. The restriction does not specify that RA registered aircraft are not allowed. I'd like to know what their definition of "ultralight" is. Many RA aircraft have transponders and ADSB in/out and better avionics than many old GA aircraft and almost every modern aircraft from powered parachues and up is far better than old Tiger Moths and Austers.

You couldn't hide an airtag on a small item like a SE2. At 32mm x 32mm & 8mm thick t's the first thing that would be discarded and left where the SE2 was stolen from.

The hexadecimal code provided by CASA is linked to the serial number of the SE2 so if the robber tries to use it it can be tracked. They cannot get another code for it and by deleting the code it will not work so it will be completely useless to the robber. You should report it stolen to CASA.
