Any thoughts on the contents of a first aid kit in a plane. It might be good to look at what caused pilot incapacitation and see if the contents of a first aid kit would help. Should you have an epipen, as it's a broad spectrum treatment for a number of ailments though they're a bit difficult to get over the counter.

I'm not against medical assessments per se, as the person with the risk factors often doesn't perceive the risk well. However the reverse it also true where it's often difficult to discount a condition with a demonstrably low risk. There is often an issue of perceived risk vs actual risk and this appears to be significantly higher when dealing with medical issues. For example I have very mild asthma, which tends to only flare up when I am ill and leads to me feeling uncomfortable rather than suffering respiratory distress. During my initial medical assessment my DAME agreed that it was so mild as to not present an issue and not to require any special controls. CASA required further investigations which led me to spending many hundreds of dollars which demonstrated that my Spirometry results were normal. However the recommendation was that I am to carry an inhaler when I fly. While this is a fairly minor embuggerence, I did review the literature as published by ATSB and FAA relating to the incapacitation of pilots during flight which spans over 50 years, both in Australia and the US and could not find a single case of pilot incapacitation due to asthma. Heart attacks, stroke, multiple instances of food poisoning, aerobullosis (the bends), nausea, respiratory infection etc but not asthma. I did point this out to both CASA and the specialist however to no avail. So apparently statistics is no match for the vibe when considering risk so I duly pack an asthma puffer in my flight bag even though I don't have one in the house, or car or when I travel. pilot-incapacitation-atsb.pdf faa-in-flight-incapacitation.pdf

One thing that I was wondering about, the initial proposal for the Williamsdale strip was prior to the creation of solar farm. Has any of the infrastructure associated with the solar farm impacted the viability of the proposed airstrip. I noticed that the substation and the associated High voltage wires about 2k to the south. There also appears to be some new power lines between angle crossing and the site that weren't there previously. It does seem a bit odd reading through the history that the local Government suddenly cooled on the idea of the airstrip and then the solar farm pops into existence shortly after. Were they mutually exclusive?

All Good, I've done that more than once myself. So far I'm happy though I do get a bit envious of the STOL capabilities of something like the Foxbat. If only I could justify two planes 🙂

Thanks, how recent is this info and do you know if there is actually any space available. Not that it's within my budget. Where have you ended up housing your plane?

A Rutan Defiant, as with anything it's a compromise, hopefully they're compromises I can live with.

Yes apparently he needs more stables.

Noisy, inefficient and limited yes however remember that the wright flyer only went 36m. As a kit you might be able to squeeze this into an experimental category. Ducted fans/bigger props could probably significantly increase it's efficiency so it might be able to lift Clive Palmer or blow its range out to 50km. If I lived in Sydney or Melbourne I'd be more interested. For instance, working at Macquarie Bank HQ, I could live on the Northern beaches and get to work in 10 minutes. At least until the neighbours complained about the giant hornets or a storm hit. With ADSB and a single guidance computer with autopilot you could have a 1000 of these in the sky safely.

Back to the topic at hand, the point mentioned earlier related to the proposed 11nm CTR vs the recommended 8nm CTR. Does the smaller CTR free up addition flight paths which would provide safer routes through this airspace? Would anyone familiar with this airspace and associated terrain be able to comment? If there are benefits send an email to Airservices [email protected]

From the CASA website the following endorsements can be added to an RPL. They don't mention retractable gear, centreline thrust etc. If they can be added it might be good to get CASA to update their website. The following endorsements can be added to an RPL: controlled aerodrome endorsement (RPCT) controlled airspace endorsement (RPCA) flight radio endorsement (RPFR - requires an aviation English language proficiency assessment) recreational navigation endorsement (RPNA - requires minimum flight time of five hours solo cross-country.

It might make a difference you write a letter or email to the relevant minister? Passive protests generally don't work because people are unaware that you're protesting and just end up with people going postal. You're obviously literate so start smoking those public servants with your wit and whimsy. Why not even offer a few of them a ride in your plane so they can witness the issues first hand. Flying is a hell of a lot more exciting than sewage works. Laws are there to be changed, funding is there for common goods, some Government decisions are dumb however if you don't point them out dumb wins, good government requires you to point it out to your local member and government reps. It might be worthwhile to point out that Government security clearance to the Secret level is valid for around 10 years, a Top Secret for 5 but for some reason an ASIC card is only valid for 2 years. Why can't ASIC clearances be available for the same period as a NV2 or TS clearance? The process behind the first two is a far more involved. From the technology viewpoint the ASIC cards aren't good, they're just a bit of plastic with a hologram, even a phone card SIM is millions of times more secure, it reeks of security theatre. I don't think that phone apps are particularly secure however they're orders of magnitude better than an ASIC card. The 9/11 attacks demonstrated that you can weaponize public transport however there were many mitigations which would provide a more effective control than ASIC cards and fences and security guards around regional airports are an expensive folly.

So the multiple burner turbine gains efficiency by a second or third burner stage between the turbines to keep the peak temperatures down but the average temperature higher, improving efficiency? Out of curiosity, what are the physical dimensions of such a creature as it would no longer have the high bypass section just the core. Essentially if you needed a lightweight portable power source what sort a minimal footprint are you looking at if you're willing to sacrifice the secondary efficiency measures that you're normally concerned about with power generation.

I meant to say "Aviaiton Turbines" 😉 Stationary turbines and marine turbines have achieved greater efficiencies as shown in the embedded link. It is an interesting time for engines as most research dollars will be going into electric. An indication of how difficult it is to make turbines efficient is this article where a rotary engine is embedded in a turbofan type engine. As rotary car drivers know they're thirsty but it would appear that they can provide a better combustors than a can. Not that is was a successful concept.

Hi, Generally in the GA market turbines aren't popular because their efficiency doesn't match that of their piston driven brethren, especially during part load conditions. As Geoff pointed out this is limited by the compression ratio and the temperature in the burner, turbine inlet area. You can gain some additional efficiency using a recuperator but it's fundamental physics that limits turbine efficiency. Turbines can be efficient however this is at the cost of exotic techniques and materials and generally only happens in large engines. Piston engines for all their faults efficiently provide high compression and high combustion temperatures especially with diesel engines, however average temperatures are low as combustion is intermittent. Piston engines also tend to run more efficiently under part load scenarios whereas turbine engines tank under these scenarios. So really you need two engines for takeoff and cruise on a single engine. I would like to know more about this engine, especially what the pressure ratio is and what the combustion/turbine temperature thresholds are, and if there is a working prototype. Continuous combustion is a hard engineering nut to crack compared to intermittent processes. If as you suggested you're using commodity materials I'm struggling to see how this can be achieved, but I hope that you succeed. There's a nice article on BFSC on wikipedia where they've collected information on lots of engine. Notice how the smaller turbine engines efficiencies tend to suck. Another key feature is that WW2 piston aviation engine efficiencies still beat the best very best turbine engines. I occasionally wonder what they could do with modern injectors and turbocharger technology.

There was some prior flying and there are also US based schools which offer 21 day programs so its not out of reach. The key point is that due to the nature of the program the instructors are very aware of your weaknesses and can tailor the day's program to bolster those skills. Luckily they could offer to instruct 7 days a week. They were very clear up front that there were no guarantees. One other thing that I did was take a PC, flight sim, large monitor and the peripherals with me to practice during the off hours. This was mostly to effect consistency of the mechanics rather than polishing techniques. I don't find the experience in a flight simulator translates particularly well however aspects of it help. As has been pointed out there are weaknesses with the approach but on balance I did start out on the other pathway and it wasn't working for me. One other benefit is the completion rate. Even if you don't get through, you're 95% of the way there, it's much easier to finish. I'd really like to know how many people do a few lessons and then give up after life gets in the way, there could be twice the number of people flying if these completion rates were better.

I think that is a great idea. Also any information related into the decline of aerodromes when fees are introduced.

My main concern is that the recommendation on page 71 of the JOINT CASA AND RAAF AERONAUTICAL STUDY OF WILLIAMTOWN AIRSPACEOctober 2015 states that Finding 13 The Williamtown CTR could be reduced in size without compromise to operations. Recommendation 13 An ICAO based CTR should be adopted at Williamtown. Their recommendation was that an 8 NM CTR should be adopted. The proposal shows an 11nm design. This is basically 2x the area of the recommendation which would appear to be a bit of a scam. They didn't justify why such as large deviation from the recommendation was required.

About 3 weeks in total. I had some prior lessons however that just wasn't working for me and I did the theory by myself as I prefer learning from books and I'm good at maths/chem/physics. Of course the instructors did ask theory based questions however that was more applying theory in practice type instruction and briefings. Flying 2-3 times a day generally in 1-1.5 hour blocks depending upon the weather and no real weekends 7 days a week to trying to fit in the necessary hours. Stressful but a thoroughly enjoyable experience especially if your work is reasonably high stress as you can't think about work when you're trying to fit in checks, calls etc. Doing the Navigation work tended to clock up hours faster as the trips were longer and more complex with detours etc. Lots of work in different environments, airspaces etc. The other key was that my instructors agreed to be a bit flexible, early starts etc, and I was too working in and around their normal students. I think that in many cases its good to fly when you're not at your best. It highlights where you're weak and need to compensation. The first flight of the day you're always pretty good, by the third flight no so much. It made the navigation and final exams easier because I had become somewhat used to a demanding schedule over a longer timeframe. It could have been done in a slightly shorter period with better weather but the experience gained was good.

For a really GA aviation friendly airport look to Christmas Island. In their wisdom the Department of Infrastructure, Transport, Regional Development and Communications decided that $300 per movement was a reasonable fee for all planes under 20T When questioned about this they stated that these fees were equivalent with other airports such as Kalgoolie, Geraldton, Learmonth & Port Hedland. I pointed out that their charges were at lead 800% higher than their "Similar Airports" and suggested that they might consider it in their next review of fees and charges. While they are meant to conduct regular reviews they didn't actually. A 750kg single engine piston plane landing at Kalgoolie would be charge a landing fee of $0.00 A 1500kg twin engine piston plane landing at Kalgoolie would be charge a landing fee of $19.75 A 750kg single engine piston plane landing at Geraldton would be charge a landing fee of $0.00 A 1500kg twin engine piston plane landing at Geraldton would be charge a landing fee of $25.50 A 750kg single engine piston plane landing at Learmonth would be charge a landing fee of $7.50 A 1500kg twin engine piston plane landing at Learmonth would be charge a landing fee of $35.47 A 750kg single engine piston plane landing at Port Hedland would be charge a landing fee of $17.95 A 1500kg twin engine piston plane landing at Port Hedland would be charge a landing fee of $35.89 A 750kg single engine piston plane landing at Christmas Island would be charge a landing fee of $300.00 A 1500kg twin engine piston plane landing at Christmas Island would be charge a landing fee of $300.00 Landing at Australia's busiest Airport which is considered expensive is would incur the following costs. A 750kg single engine piston plane landing at Sydney's Kingford Smith Airport would be charge a landing fee of $60.00 A 1500kg twin engine piston plane landing at Sydney's Kingford Smith Airport would be charge a landing fee of $60.00

I can't comment on the average age of the GA training fleet in Australia with any degree of rigour, however the average age of the GA fleet in Australia is 40 years. Guys this is average age, so for every new plane there's an 80 year old one. A significant percentage of these planes are used for training purposes so I find it very unlikely that the GA training fleet is anywhere near the 5 years figure. You may be able to cherry pick an individual flying school which meets those figure but only by excluding complex training requirements like twin engines etc. Also the average aircraft age has been increasing for a number of years, so the situation is getting worse. The average age of the regional turboprop fleet is over 23 years. Yes the average age puts them into the previous century. From an engineering perspective the situation is even worse, the technologies which can make flying safer by relieving pilot workload are missing in action even on new planes. For example lets choose a situation which led to an accident 20 years ago. From the ATSB reports a mechanical failure due to leaded fuel cause detonation causing bearing failure and engine loss. The second engine was lost due to high power settings and detonation. Fast forwarding to today and the same failure modes are likely to occur for the following reasons. Leaded fuel is still in use leading to buildups and hot spots. The majority of engines in common use removed this fuel type > 40 years ago Poor engine design, fuel mixture control is still a manual process. The majority of engines in common use automated this > 20 years ago Poor engine design, Engine instrumentation is still poor due to lead in the fuel. The majority of engines in common use oxygen sensors etc. > 20 years ago Poor engine design, Detonation detection is not used. The majority of engines in common use detonation sensors etc. > 20 years ago All of the above should have been resolved 20 years ago, leaded fuel should have been phased out as it's a neurotoxin. Engine control should be automated, it not expensive as the components which do this cost less than a pack of cigarettes. For example some people will say that you can't use sensors to detect detonation in an airplane engine because they're too noisy being aircooled. However detonation can be detected electronically by running a current through the sparkplug post ignition, it's how Mazda, Saab, BMW etc detect preignition. It's an old technology and it's introduction would make the GA fleet safer. There is currently a debate about whether helicopter cylinder failures is being caused by low lead petrol in hot inland areas. This is not an issue with fuel it's an issue with defective products, poor instrumentation and controls allow the manufacturer to squirm out of the accountability issues. There are design solutions to all of these problems however there is no incentive to include them by default. Fuel injection replaced carburetors because of emissions targets, prior to this it was seen as a "premium" product which you would pay more for. Now you can't buy a carburetted car, cylinders all get an accurate amount of fuel. Compare this to the aircraft industry, you have to pay more to buy "matched injectors" if you're lucky enough to have injection in the first place.

The advantage of the training was that with the compressed training virtually all weather types were encountered with temporal continuity, because it was done in early spring and early summer. Training was done in two stints, in September and in November. A number of different weather types were encountered ranging from Southerlies blowing in, low cloud, hot and high conditions, unstable air masses with lots of energy, very dynamic weather conditions etc. A key advantage was that the continuity allowed you to participate in predictions a number of days ahead as you tried to schedule sessions across variable weather. For example starting at 6 or 7 am flying in OK weather, then having a briefing session and the weather deteriorating to an extent where I wasn't comfortable flying. Even during circuits over the period of an hour the conditions going from good to challenging and making a risk based decision to call it a day (I could still fly however it was the trajectory that concerned me and that was a good lesson as I was briefed on this possiblity). From a business model perspective spread out lessons can make it easier for the instructing business, however this shouldn't be conflated with what is best for the student which I suspect is often the case. What is the better model for students is debatable, I think based upon my experience is that the compressed training can be significantly better both in terms of cost and experience. As stated I flew in a season with extremely variable weather, this caused some delays and days lost however it was great experience and this cost was definitely worthwhile . Compressed training in Summer with day after day of clear skies may lead to a different outcome. Similarly with different instructors there are another set of pro's and cons, when teaching/instructing a set of students over a long timeframe a lack of continuity is very apparent. Each time you change instructors there is a loss, each time there a delay of a few weeks there's a loss as they struggle to grasp where you fit in their mental model of training. Compounding this is the fact that as you spend time away from the controls is that technique atrophies as well. It well known and accepted that changing a school teacher mid stream during a course has a negative impact on students, and that some teachers are better than others. This doesn't mean that schools randomly change instructors to make up for this variation on quality so I'd take the 'multiple instructors' piece with a grain of salt. This isn't saying that there isn't value in specialist training just as there's value in a science teacher teaching science and a maths teacher teaching maths however doing your basis pilots licence you're really in primary school with a generalist instructor. Of course there may be value in spending 100 hours of instruction with multiple different instructors to average out the lack of quality with some instructors, however most people contemplating getting their license don't have the luxury of time or budget so they need to compromise.

In general I think that GA needs to do more PR work, look at the bikies charity rides currying public goodwill. The whole Angel flights program should be advertised more widely and activities involving the locals should occur on a regular basis.

One thing that hasn't been mentioned is that the Grafton Airport which is maintained by the Council is about 12km out of town so Grafton has two aviation facilities, one for commercial and the other catering to the local flying community. The fact that it is much closer to town is a significant plus.

You can do a number of hours each day and yes your rate of learning may decline but it's not extinguished, from my perspective the decline is significantly lower than that associated with intermittent training over a longer period so from a value perspective it's significantly better. We expect school students to learn for longer periods than an hour so I don't think that there's a fundamental issue with the process. Staggering actual flying and briefings with higher and lower intensity tasks can work well. More study in the evenings, it actually helps if you're not at home. Another advantage is that when you fly you will encounter situations when you aren't at your best and have already done several hours of flight. It helps if you have been through a training situation when you are tired and someone is picking up on your faults and errors. Yes you're not at good when you're tired, what techniques help to counter this. In the military world this is a standard part of their training as they know operations can have a high tempo. Theory first is a good idea, which the practical reinforcing and broadening the theoretical base. It is a hard slog bringing back memories of some weird hybrid cramming for exams and pre-season training, but rewarding none the less as your progress is a tangible thing.

It seems strange that they could bill incorrectly for a flight into controlled airport with controlled airspace. Unless of course they farm the voice recordings to someone not familiar with the english language. I was interested in the solution that Caboolture were using. The issue with radio calls is that they're easy to fake or mistake. I'd like to see ADSB made mandatory for all flights and also have the Government provides an open source ADSB reference design and test compliance suite and program. This would drive the price down to a nominal cost so that the price reflects the components. However the ADSB standard is an incredibly dumb standard, signals are easily spoofed and have less security than a standard phone handset. It really does need to be fixed.
