Signing a waiver before carrying out an activity considered to include risk of injury or death does not prevent the estate or relatives suing. The law should be amended to stop this so long as the waiver is not signed under duress. The Kiwis can't sue when an accident causes injury or death. This was enshrined in law nearly 50 years ago when they set up their Accident Compensation Commission. Of course lawyers & the insurance industry hates it as it derives them of easy income. The commission is funded by employer levies & motor vehicle CTP but covers all accidents. There was so much money in the coffers that they reduced the CTP on car registration dramatically that it cost only $80.00 a year to register a car inclusive of the ACC levy. A similar system needs to be set up here. Australia is the second most litigious country on earth after the USA.

You don't need any aerofoil to fly. A flat board will provide the lift when the angle of attack and thrust provides enough downward force to overcome the gravity of the mass of the machine. It will just be hopelessly inefficient.

The flying Bum (Airlander 10) has been around for a few years as a prototype & now they have a production version which is currently undergoing certification. It has a 10 ton payload 4000nm range, can remain airborne for 5 days at up to 20,000 feet. The current version is turbine powered but they plan to electrify it fully by 2030. Their next model has a 50 tonne payload & can carry 6 ISO 20 foot containers plus 40 passengers or 200 passengers.

How about the flying BUM. https://www.hybridairvehicles.com/news-and-media/overview/news/new-aircraft-shape-revealed/

Drones can do anything a manned aircraft can do and more these days. But even in 1965 the Hawker Siddeley Trident was the first commercial aircraft that could land itself. Originally designed by de Havilland it was capable of landing in complete whiteout conditions & it was only due to the fear of failure from Aviation Authorities and the public that it was eventually not allowed to do so. It was the most advanced and first trijet built, originally designed in 1957.

Nope, Bluetooth is complex but entirely explainable with zeros and ones, algorithms using packet data and spread spectrum technology over very short range in the 2.4ghz spectrum & so I imagine drones use similar technology but over a different radio spectrum and have physical interfaces via electric motors controlled by the software.

So long as the aircraft is factory built, with a current maintenance release and has dual controls an authorised Instructor GA or RA can train you in it. If you have built your own aircraft you can be trained in it as well.

All the aerodynamic theories of Bernoulli, mathematicians, physicists, scientists, aeronautical engineers etc is BS. I know what it is, IT IS MAGIC. Proof below.

The difference between turning back and not turning back for most pilots and aircraft is you are more likely to have a controlled crash or even a lucky out landing escape by not turning back.

Upwind, downwind, crosswind doesn't matter. You fly at the same speed relative to the air. The speed and direction across the ground, well, that is a different matter.

New battery technologies will probably render current Lithium ion batteries obsolete within 10 years. LiFePO4 batteries have already been able to get rid of cobalt but at the expense of energy density. Another new cobalt free battery technology using nickel, aluminium & manganese for the cathode in Li-ion batteries claims higher energy density giving up to 800km of range. Some of the new technologies will have a flow on effect for Aviation. Some of the major technologies are specified in the Green Cars publication at https://www.greencars.com/guides/the-future-of-ev-batteries

The BYD blade battery is not a good shape to power aircraft. It is 905mm long x 118 wide & 13.5 high (thick), 3.2 volts with a capacity of 202 Ah. The Tesla type of battery of multiple cells in 18650 (18mm x 650mm), 21700 & 46800 sizes can easily be configured in to shapes that fit a given volume. 18650 Li-ion batteries have been around for a fair while now but the improved LiFeP04 type it is safer as it won't explode or catch fire like standard Li-ion, it is cobalt free, can be discharged fully without degradation & recharged 3-5000 times. but has lower energy density that Li-ion. In any aircraft application weight is the main problem.

2030 is the year that the sale of new ICE cars will be banned in the UK. Existing ICE cars will continue till they disappear naturally. As petrol is getting very expensive that may be sooner than we think. Some car manufacturers have already announced they will cease producing ICE cars by 2030. BYD, Ford, GM, Jaguar Landrover, Mercedes Benz, VW, BMW, Volvo, Jeep, Peugeot, Fiat, Citroen & Opel have pledged to cease ICE production by 2040. Toyota plans to only produce only 10% pure ICE vehicles by 2025, the rest being Hybrid or pure EV. BYD has already ceased production of pure ICE vehicles. Battery technology has been improving at an astonishing rate in the last couple of years and will continue to improve dramatically over the next 8-10 years. Energy density of batteries continues to improve as well. New high end EVs have already cracked the 1000 km range barrier. BYDs blade battery is so safe you can hammer a nail through it & it won't explode or catch fire. There are 170 manufacturers of Electric vehicles in China producing more than 300 different models from Mopeds to super luxury limousines. The cheapest BYD EA1 or Dolphin is a small hatch EV the size of a Corolla that sells for $AUD20,200.00 in China. These go on sale in Australia later this year. This is the future like it or not. Hang on to that ICE car for as long as you can if you don't like electric. The price of petrol though will eventually have all the dyed in the wool ICE forever people rethink their commitment.

It was in the NTSB interim report.

You obviously missed Octaves post with information from the US ATSB. EV car fires 25.1 per 100,000. ICE car fires 1530 per 100,000. No contest, ICE cars are 61 times more likely to catch fire than EVs.

The design patents would have expired years ago. This is not a modern engine design by any means.

Conclusion. Don't turn back. These were all highly skilled and trained pilots. A good comparison would have been to find 3 pilots with normal flying skills who have never tried or practiced turnbacks & checked the results. The risk though would have been a stall/turn & crash. If not I doubt that any except the cub would have made it & they were all from 1000 feet. The cub was from 300 feet twice & 500 feet once & the stall warning was going off most of the time. He made it due to his expertise but the stall warning should have invalidated the test IMO.

EFATO and stall at under 300 feet. Guaranteed crash, usually fatal as it was in this case. Shame they took out someone on the ground as well.

Dan Gryder has called this one out. The passenger was a friend of the Pilot and had flown with him probably in the right hand seat on many occasions, possibly in the hundreds of hours. The guy just wanted publicity so didn't say anything about this & is possibly a religious nut case by saying it was God who got him down safely so he knew he wasn't going to die. As Dan says maybe a nice guy but he is a liar.

Some of them didn't cope well but they learned quickly or died.. As well as getting shot down the accident rate was very high. A lot of the dog fights started at very high altitude (up to 20,000 feet) so if a stall or spin occurred at that altitude there was plenty of recovery room.

All appears to be back to normal now.

The only thing that will prevent food poisoning is to not eat the food that poisoned you. Easier said than done as you don't know about it until some time after eating & no-one (other than somebody suicidal) would deliberately eat some food knowing it would poison them. No prior medical is going to help at all.

In the recent flood at South Grafton aerodrome we had a metre of water through most hangars. All my power tools, 2 lawnmowers, 2 x electric pedestal fans, cables etc were submerged for 4 days. When I canoed to the hangar & went in to check on things I accidentally knocked my portable radio off the table & it sank to the bottom. I retrieved the radio took home and pulled it apart. Then I sprayed it in every nook & cranny with clean water to get rid of the dirt reside from the flood water. I left it to dry naturally for about 4 days. I put the same batteries back in, turned it on & it worked perfectly & still is. I just hosed all the power tools, wiped the exterior clean and the fans to get rid of flood water residue & left them to dry also. All work as if nothing had ever happened. The lawnmowers were full of water so I replaced the oil & fuel dried out the air filters, removed the plug & spat all the water out, got the water out of the priming bulb & float bowl, reassembled it all & left it a week to make sure the magneto was dry & both started after a couple of pulls. Electronics don't like getting wet but if the boards have been properly lacquered a good clean & then left to dry without any artificial assistance & they will more than likely suffer no ill effects.

How many manufactured electronics etc do you buy that are not made in China or have Chinese made components? The answer is very few. The big names like Apple, LG & Samsung all have Chinese components but the quality control of these is managed to a very high standard. The Chinese are leading the world in new battery technology production with CATL & BYD. BYD will be selling sub 45k BEVs in Australia from July. I'd like to see how the quality of these pans out.

When you log in, it will be in reminders on the Welcome page. If rego is not due nothing will be there. Same with your membership. You can check all your details by clicking "Manage my membership" at the top right of the screen next to "log out". There you can check your aircraft and membership details & when renewal is due etc. This is from a PC. If you use a phone or tablet it might be different. If so just ring RAA & they will tell you..
