  1. Cora seem extremely dedicated to making the "autonomous air taxi" a reality. IMO, they've still got a long way to go. Regulation and guidance are the fields that pose the most problems for them. It's interesting to see their aircraft design progression, from rather radical first designs, to essentially following some pretty basic light aircraft design. Their aircraft seems like a very viable and adequately reliable product. But I feel it will long be restricted to a "privileged group" of people, who will pay a lot more to go direct by air taxi, and who are happy to pay more, to avoid traffic congestion. https://cora.aero/blog/

    But .. but .. if the wind blows the card away, you no longer have any method of measuring the weather!!
  3. The ABC is reporting a double fatality (two males) in a gyrocopter crash into the sea, off Forrest Beach, North of Busselton, W.A., around 14.00hrs WST today. The crash site is closer to Capel than Busselton. My sympathy to the deceased mens families. No names have been released yet. Gyrocopter crashes into sea off Busselton, two killed
  4. If the folding rotor mast cheek plates are failing in service, it shows the regime and methods for the testing of the strength of the cheek plates, is deficient. More than one testing arrangement has proven to be inadequate to replicate the actual forces applied in normal use - and if the owners are carrying out manoeuvres that can be classed as being outside approved limits, then that's a whole new ball game. There's plenty of people out there operating things to past their design limits, just to, "see what it can do".

    Jabiru LSA vs 160

    Spare a thought for the poor buggers flying the Double Sunrise Qantas PBY Catalinas, Perth to Ceylon, during WW2. About 4 tons overweight on takeoff with monstrous additional fuel tanks fitted, they took off from Melville Water at Crawley, running 48 inches of MP and with the P&W R-1830's producing their intermittent maximum power of 1200HP each. They took up to 80 seconds to get clear of the Swan River, and with a climb rate that could be only be called "leisurely", they generally only just cleared the Fremantle railway/road bridges by around 100 feet, some 12 miles downstream. I have not seen any times quoted for the Catalinas to reach their 1500' initial Westbound cruise altitude, but I would not be surprised if it was around 20 minutes or more.

  7. I think the news of the A380's demise wasn't exactly unexpected. If it wasn't for PetroDollars, AB would have been struggling to sell many at all. The costs of altering hangars and servicing equipment to handle them must have been immense. I always pondered what would happen if one of them crashed as a total loss, with all aboard wiped out. I bet it gave a lot of emergency agency bosses, sleepless nights. How do you deal with up to 800 bodies in one air disaster, and a vast amount of destruction on the ground? Hospitals would be overwhelmed, they struggle to cope with modest disasters, now. My thoughts were, that if one crashed, it would be the final nail in the A380's coffin. But, it appears my thoughts were too negative, and the rule that the bigger the aircraft, the safer it is, is correct.

    ME 262 Sturmvogel - Was Hitler correct?

    Hitlers decisions were flawed on every front, in every month of every year of WW2. He demoted or destroyed those who had the necessary skills to improve the Luftwaffe. He ordered that all components produced, be turned into operational aircraft, leaving no spares for support. The reasoning behind this, was Hitler wanted to demonstrate superior numbers in available equipment to the Allies. The end result of his faulty reasoning and orders was that, when the Luftwaffe aircraft started to break down, there were no spares to repair them - so the Lutfwaffe were forced to turn to cannibalisation of working aircraft to keep others going. Hitler spent vast amounts of time and money carrying out genocide on a race of people he detested. That act alone took up substantial manpower and money to carry out. He utilised half-starved POW's and some Jews to carry out labour tasks in his industries. As with the Japanese with the Bridge over the River Kwai, the Aussie POW's forced to work on the railway and bridge deliberately slowed up progress, and damaged equipment. The POW's and others forced to work in German operations would also have deliberately sabotaged and slowed up operations. It would have taken a lot more Germans to watch over the forced labour to ensure they didn't sabotage operations. Time after time, Hitlers understanding of tactics and strategies was proved to be woeful. Starting a War on one front against one implacable enemy, then starting a War on another front, in the exact opposite direction, isn't exactly the way to win wars. Hitler engineered the death of many of his most capable leaders in his ranks of senior officers, and replaced them with incompetents who were picked because they were toadies. On the Eastern Front, Hitler refused to take the advice of his most senior Generals, to fall back in a strategic retreat, when the Russians were threatening to overwhelm the Germans. Hitler told them they must not retreat, and they had to fight to the last man. They did exactly that, and it cost Germany hundreds of thousands of experienced fighting men, as well as losing vast amounts of German equipment to the Russians. No decision of Hitlers regarding aircraft ever had any vestige of success, simply because all his thought processes were flawed, he lacked full understanding of strategies and tactics, and he was driven simply by rage against Jews. As WW2 progressed, his decision-making became more and more flawed, and even some of his most senior officers went against his orders, numerous times. Any decision of Hitlers involving aircraft, would have been made for all the wrong reasons.
  9. No, I didn't want to kick him because of tall poppy syndrome, arrogance, or general cantankerousness. I thought about kicking him off his bike to stop him, and to give him a lesson that cones and traffic lollipops, to divert traffic, are there for a reason, the road rules that apply to everyone else, apply to him, too - and that he was effectively riding through an exclusive pedestrian area (same as a footpath) - and he could have easily mown down a kid, a dog, or a senior - and come a cropper himself, as well as injuring someone. I agree, there's plenty of smart-arses amongst the truck drivers and car drivers - but young motorcyclists seem to have turned it into a fine art, with total disobeyance of road rules at every turn. By far their greatest weakness is failing to understand, that screwing the throttle on full, on takeoff from the lights, and hitting 100kmh within 80-100M, will soon ensure a short lifespan. We've got a roadside memorial just up the road for a 19 yr old motorcyclist who did just that. The problem was, as he crested the rise in the 4 lane road at 100kmh (in a 60kmh zone), there was a bloke turning right into the shopping centre. The motorcyclist slammed into him, he went over the bonnet and landed head-first on the bitumen, and he was history. But everyone wailed about what a fantastic bloke he was. AFAIC, I don't have any sympathy for him, it's the Darwin selection process at work. But I do have sympathy for the parents and family left behind, that he had little regard for. The problem is, I guess, he had little regard for his own life, let alone anyone elses.
  10. It's because there's a fascination with flight, and the ultimate fear is crashing to the ground with sudden death, and often what appears a terrible death, the result. It's even more fascinating because the people who fly are generally "high-flyers" in society. The media love it and play on it. But, as regards motorcyclists, very few people care about motorcyclists being killed, because they're seen as "smart-arses" who like to ignore road rules, slipping between vehicles up the centre of lanes, always doing 20kmh over the limit, and always wanting to be out front. I was at a street market last night, the traffic control people block off the kerbside lane and just leave one lane for traffic, while the kerbside lane is blocked off for the pedestrians to mill about on. But one smart-arse motorcyclist decided he could ignore cones and rode his bike up the kerbside lane inside the cones, just so he could beat all the line of banked up cars. I felt like kicking him off his bike as he roared past. He's a cert to wipe himself out within a year or two - and the reason why motorcyclists are largely hated. Not to mention the Harleys with 130dB exhausts, who just have to blow your eardrums, because they need to show off.

    BalanceMaster testing

    The only problem that I can see is, acquiring washers with the correct OD and ID to ensure they're a snug fit. Any gaps would allow movement to start. I'd machine up some solid bushings to ensure the fit is precise, as regards OD and ID.
  12. Aww, c'mon Nev - you've seen those montrous swing-down, full-body harnesses, that the space travellers use in the movies. We've got ways of designing equipment, to stop pax from wriggling around in flight.
  13. I'm advising you I'm taking offence at the "short" notice wording. As a sensitive, vertically-challenged person, I take offence easily at anything being called "short", with my impressions being, that the "short" was actually aimed at me. My feelings are hurt, I'll have to talk to my lawyer. You should have used some other, non-discriminatory word, to avoid hurt feelings.
  14. I guess they could have a sliding seating mechanism which could adjust the C of G automatically, via sensors. With no need for the pax to be in a certain position to operate flight controls, they can be moved around to meet the C of G requirements.
  15. Well, the solution is simple - same as the airlines, someone will have to oversee the people boarding, and refuse boarding to those who do not comply with the regulations. The greater problem will be in regulating the flights as regards traffic control in the air. Maybe the authorities will have to reserve a complete new flight level for these things, say 200 to 400 feet.

    Are you happy?

    Facthunter - The answer to your problem of your computer "eating up" the letters ahead of where you're typing, lies in the "insert" button. Sometimes, one accidentally hits the "insert" button when editing, this inserts the letter you type, but deletes the next letter. Hit the "insert" button again, and this toggles off the feature.
  17. It's certainly a very strange choice for a paint scheme, for a civvy arcraft. Make you wonder what the thought processes were behind it. I note the family were into Paintball, I guess they were really right into war gaming, shooting, and military stuff, and really wanted to carry their obsession to the extreme. The sad part of the whole disaster is that the son was an only child, so the widow has lost her whole family in one severe blow.

    I think the testimonial on the Liquid Containment website is particularly good. The odour-proof barrier is critical, as regards confined spaces. Liquid Containment 16/20 litre jerrycan
  19. The Channel 7 News video in the link below, gives good imaging of the damage to the top side of the Gyrocopter. I've pulled off a couple of screen shots from the video, that are pretty telling, as regards the failure point on the rotor mast. Tributes roll in for Gyrocopter crash victims
  20. Well, here's your chance to max out the CC's, and get yourself some pieces of Australian military history! Graysonline are holding an auction of 22 ex-military Bell Kiowa 206B-1's, 5 Pilatus PC-9/A's, and one Westland Scout helicopter. The Westland Scout is the most historically interesting machine. Seems like it's the sole survivor of 2 purchased by the RAN in 1963. The Scouts were used aboard the Hydrographic Survey ship, HMAS Moresby from 1963 to 1973, when they were replaced by Kiowas. The second RAN Scout ditched into Wewak Harbour upon takeoff - but despite being recovered, it was deemed a write-off. Note that none of the approximately 150 Scouts built, ever received a civilian CoA - they were all operated under military control and conditions. Note also the onerous T's & C's attached to the sale of all these aircraft - none have CoA's - no support whatsoever for them, will be forthcoming from the Commonwealth of Australia - and they are sold, AS-IS, WHERE-IS. Grays also make it clear that, "Potential purchasers should make themselves aware of any CASA regulations pertaining to Ex-Military or unregistered aircraft." Graysonline - Unreserved sale of ex-military aircraft and helicopters
  21. I was stunned to see the RAAF stating that the Kiowa's had accumulated a total of 480,000 flying hrs over their lifetime. With a total of 56 purchased (with the first 17 machines built in the U.S. and the rest built by CAC), that equates to approximately 8500 hrs per machine. I'm not sure what the design life hrs would be for these choppers in military use, but I would imagine 8500 hrs would be approaching their design life limit. I guess one thing in their favour is that most have rarely seen combat. The Vietnam War was practically over when they were taken on register, but I guess some may have been used in other, more recent wars and skirmishes.
  22. Ahem .... Downunder, there's a little snag in Plan A ... but I'm sure a man of your extensive capabilities will soon arrange a way around it. Shipping to NK via a remote South Pacific Ocean Atoll, perhaps?? "The export of vehicles with military origins is controlled by Australian legislation. Buyers will need to submit an application to export controlled goods to - http://www.defence.gov.au/deco/DECS.asp - or call the Defence Export Control Office (DECO) on 1800 661 066 to ascertain if Export Approval is required."
  23. The names of the deceased have been released - they were Father and Son, Robert and James Waughman, from the Perth suburb of Kallaroo. Busselton Gyrocopter crash victims named Perth Now - gyrocopter crash victims named Their gyrocopter has been positively identified as a Titanium Explorer model, G-565, S/N 036, camo green/brown/black - new, 09.2017.

  24. Examination of one of the Busselton crash Gyro recovery photos, appears to show that the lower portion of the rotor mast is all that is left of the mast assembly. Then, examination of the TAG website photos, showing the folding mast, gives one the impression that the cheek plates holding the folding section of the upper mast assembly, do indeed appear to have failed in the Busselton crash Gyro. None of my conjecture is designed to interfere with, or encroach on, any properly-instituted crash inquiry, or predispose any person as regards fault in design or operation of the Gyro, nor is it designed to reflect adversely on the TAG company, or its owners or executives. The recovery photo is courtesy of ABC (Australia) News. Titanium Autogyro - features
  25. I'm going out on a limb here - but from the little I can glean from the limited amount of photos, it appears that this machine is a Titanium Autogyro model. If I am correct in my ID - of some concern, is the report from a previous Titanium Autogyro crash on Oct 31, 2018, at Spring Hill, NSW - which crash also resulted in a double fatality. This gyrocopter crashed whilst doing training circuits, and touch and goes, at Orange regional airport, killing the instructor and the student pilot. Investigation of this serious crash is currently being carried out by the ATSB - and investigation centres on structural failure of some of the (folding) rotor mast components, which appears to be the major reason for this crash. Whether the failure is a design fault, or the components were overstressed in operation is something that the ATSB is no doubt pursuing. ATSB Investigation AE-2018-073 I note that all Titanium Autogyros fitted with the folding mast option, were grounded shortly after this crash, by ASRA, after the release of an ASRA Safety Directive. That Safety Directive reads; "A preliminary investigation into the circumstances surrounding the (Oct 31, 2018) accident has been completed by Officers from the Australian Sport Rotorcraft Association (ASRA). The investigation is continuing. ASRA Officers completed an inspection of the accident gyroplane and reported that the gyroplane was fitted with an optional two (2) piece folding mast. There was evidence to support that the cheek plates locking the folding mast in the flight position, had failed. This possibility represents a major risk to flight safety. DIRECTIVE: With immediate effect, all Titanium Autogyro (TAG) gyroplanes that are fitted with a folding mast option are grounded until further notice." I have no information as to whether the grounding has now been lifted on all affected Titanium machines, or if individual Titanium machines with the folding mast have been checked, and deemed safe to fly. It is going to be interesting to find if; 1. This Busselton crash Gyro, actually was a Titanium model; 2. If it was fitted with the folding mast option; 3. If the crash was directly caused by a similar component failure, as in the Spring Hill crash Gyro.
