I stand corrected but the Wikipedia page on the BDPC states:- "The requests by the Board to US manufacturers stimulated production and design including the development and production of what would become the North American Mustang, which was designed for the Commission." And from Fighterworld.com Mustang page "One of the finest American fighter aircraft of World War II, the North American Mustang owed its origin to a Royal Air Force (RAF) specification for a single-seat fighter to replace the P-40 kittyhawk. The first flight took to the air in October 1940, with production Aircraft in RAF service by the end of 1941. The original 1,150 hp Allison engine lacked performance and once it was replaced by the proven Rolls-Royce Merlin, the aircraft excelled."

The P51 was designed from a specification produced by the British Direct Purchasing Commission to replace the P40 Kittyhawk and went into service first with the RAF so it owes its origin to that original specification and excelled with the RR Merlin engine.

Good grief, you are dredging up stuff from 2014. The initial reliability and engine failure stats that were cause for the Jabiru engine restrictions were wildly inaccurate & included fuel starvation & shutdowns on the ground etc. The initial figure was 40 but when the analysis was done it ended up as 12 & there were no fatalities involved. A couple of disgruntled ex RAA flight school operators who failed to maintain the engines as required, now working for CASA poured fuel on the issue. After the Senate enquiry the restrictions were lifted & the ex RAA employees were quietly let go. I have all the reports & details & do not intend to publish them here.

The Mustang was a British design as well. Originally a RAF specification. It was only ever built in the US but only came in to its own when they put a Rolls Royce Merlin in to it & later Packard made thousands of Merlins under licence. The US had the raw materials and workforce plus the mass production facilities of their motor vehicle industry. There were no civilian cars made in the US between 1942 & 1945 as production was shifted totally to the war effort.

It appears that this crash and the unfortunate fatality did not have an engine failure as one of the possible causes. The debate over engine reliability is therefore irrelevant. All engines are man made and none are 100% reliable. Any engine can fail. Correct and timely maintenance will reduce the risk of failure. The 4 top causes of aero engine failure are 1 fuel starvation, 2 fuel contamination, 3 carburettor icing, 4 Fuel system problems.

Only about 9 million outside my budget.

I have been testing my Skyecho2 out locally using the free app "Enroute Flight Planning". Connects automatically to my tablet or phone. Displays a green box with callsign & altitude & track of an aircraft with Mode S Xponder or ADSB out but has a maximum limit of 20 NM horizontally & and 1500 metres (4,921 feet) vertically to reduce clutter. Most aircraft I have seen are near aerodomes & most have also made radio calls but in a couple of cases no calls at all even when they are within 10NM of an aerodrome. These are the ones to keep an eye on. Then of course there are those without ADSB out or Mode S who don't make radio calls.

If it takes a month to get to number 24 it will be 10 months before they get to mine (No 244)

I keep hearing people saying that RA-Aus is against the relaxing of medical standards for GA pilots but not one person has supplied any evidence that this is the case. It is only their opinion and that is fine but when that is not stated others get on the bandwagon on an issue that probably does not even exist. The UK CAA did it properly back in 2015. CAP 1284 utilised a pragmatic terms of reference and process for conducting a survey of pilots. The results and changes to self declared medicals for all UK GA & NPPL pilots requiring only a Group 1 (car) drivers licence was published in CAP 1397 in April 2016 less than a year from the original proposal. They used evidence of accidents & fatalities over 45 years as well as the survey results to resoundingly scrap the Class 2 requirement for over 32,000 pilots. But of course we have CASA & it is 8 years later.

No but I have this problem when mowing on our large Iseki SF300 mower which is very noisy and my Grade 5 earmuffs have quite a strong headband clamping force. I have never been sure why but now realise it is the arms of my glasses & Sunnie's.

Belief systems have caused more problems that almost any other on this planet. The problem is that beliefs are not based on real verifiable evidence. Most people who have a belief in something will always find something that backs up their belief so they continue on with a blinkered vision because what they have now found out from some dubious source which reinforces that belief so any other evidence to the contrary is very quickly sidelined. Here we have a belief that the Great barrier Reef is healthy despite overwhelming evidence that it is not. Pauline Hanson said everything is great so it must be.

The move to Electric vehicles continues to increase exponentially. Here are some stats. In 2021 worldwide sales doubled from 2020 to 6.6 million. There are more sold in a week than in the whole of 2012. China has 300 EV manufacturers producing 700 different models. China sold 3.3 million EVs last year, half of the worlds sales. Europe sales increased 65% last year to 2.3 million US sales increased by 100% to 630,000. There are now 16.5 million EVs on the road world wide, 300% more than in 2018. The move to curb emissions is gaining pace everywhere & not always by choice. This is only the very beginning. Our long term ability to survive depends on it

The hour meter on a VDO tacho only activates when the engine is running, not when power is attached only. Just having the power on will not increment the time.

I land downwind a fair bit on 08 at YSGR. Not when there is 15+ knots on my tail but up to about 10 knots max. Why? Well the runway is 1200 metres long & I like to land on the grass rather than the seal which is easier on tyres and slows me down faster. Also the taxiway is at the end I am landing towards. The approach is over flat land as well with no trees or houses. The circuit for 26 is over hills and houses with trees near the threshold which has been displaced 200 metres for this reason. Usually we get fairly strong westerlies at this time of the year so 26 is the only option & with 10-20 knots approach can be reasonably steep so as to miss the trees by plenty & land before the displaced threshold & run on to the seal. Never turned back under 500' & never going to. Also never had a real EFATO.

Pathetic. We applied for Flood grants some time ago & they took less than 2 weeks, though that was State not Federal.

Has anyone who has applied for the grant received their money yet. Just wondering how efficient or otherwise the system is. Mine has only been submitted for a bit over a week. It only took 3 days from ordering my SE2 to delivery and I obtained a Hex code from CASA the same day I requested it.

You can still farm animals and raise crops on both Wind and solar farms. Studies have shown that grasses still yield 90% of what they would without solar panels. Crops yield a bit less but spacing the panels with a metre gap results in almost no loss after crops of pepper, tomatoes, beans and coriander were grown. There is already a name for it, "Agrivoltaics". Animals benefit from solar panels as they provide shade. https://www.renewableenergymagazine.com/emily-folk/how-solar-energy-can-coincide-with-crop-20201119 We are a long way from the original topic now.

You have no idea. Coal wastes most of its energy as heat. The average Coal powered electricity generation plant is about 33% efficient. Look it up. Along with Oil & Gas it is the largest single source of greenhouse gas emissions on the planet.

Baseload power is a misnomer in todays world. What is required is fast generation to deal with peak demand. Coal simply cannot do this as it needs to run at close to full capacity all the time to gain its maximum efficiency which is poor anyway. Nuclear is similar. Gas can be turned on fairly quickly but not quickly enough when there is peak demand. Hydro is pretty quick as the turbine gates can be opened within a few minutes. Electric power batteries are almost instant. The Tesla battery in SA has proven this a number of times. It is not large and cannot supply power for long but has the ability to kick in instantly and give other generation methods time to ramp up. The only reason off peak power is cheap is that coal generators can't slow the ouput down so it has to go somewhere and there needs to be an incentive to take it. A study done some 10 years ago by Sydney university identified more than 10,000 potential pumped hydro plants in Eastern Australia. Not one has been developed to date. Snowy 2.0 is proving to be the monolithic disaster predicted by the experts but rubbished by the Turnbull/Morrison government. What we do lead the world in is rooftop solar. A week or so back more energy was produced for a short time from solar (rooftop & solar farms) than coal. This is only a start. One of the biggest problems of course is the grid which is old and not capable of dealing with a major failure somewhere due to transmission distances and the huge energy losses with long distance transmission. There are many parts to the solution and local battery storage is just one where excess rooftop solar from a group of houses is stored in local batteries either in the houses or a centralised location. This is easy electronically. You get paid for excess solar going in and pay for what you take. Batteries are getting cheaper with numerous new technologies not far from being available and the transmission losses are minimal.

I purchased a Bolly BOS 5 (Bolly Optima Series 5) 2 blade prop for my 3300A engine in 2018. It is the top of the line Bolly and came as a kit with all hardware and a manual with installation, pitch adjustment settings, maintenance etc and certification including balance data. My assumption is that the Jabiru Scimitar would be produced to the same level of detail. The Scimitar price is a quite a bit higher than mine but it is ready to fly. The Bolly website shows that the price for the BOS 5 has not increased since 2018. Inclusive of Spinner and freight to me I paid $1,709.00. There was some work to do as I had to assemble everything, do the cutouts for the blade in the spinner, install the nut plates to the back plate and drill the attachment holes in the spinner & of course set the pitch. It took me about 4 goes to get the pitch where I wanted it which was and still is 3300 rpm S&L at 2000 feet.

Nor looney unvaxed conspiracy theorists.

The Scimitar prop is made by Bolly for Jabiru and is preset to their recommended pitch. It is ground adjustable though so if the pitch doesn't suit your kind of flying it is easy to adjust.

I saw that Avweb alert this morning. Gami have had all sorts of delay thrown at them from the FAA since they made the first proposal back in 2009.

I certainly noticed the big increase in feeling turbulence when migrating from heavier GA aircraft to RA. It was different when hang gliding as it often indicated thermals and lift and my mindset didn't really consider that turbulence at all. The worst I have had in my current RA aircraft was when at around 8000 feet with a very strong tailwind of about 50 knots I had to slow to 70 knots to even feel partly safe. There was no point trying to fight it. I just went with the gusts and survived.
