  1. It is a wildly long shot of an idea, but what if people wrote to Sales at BP and explained that, although they were a small users of avgas on an annual basis, they still are customers. Does BP decline to provide small amounts of fuel at its service stations for the person who needs mower fuel? Do they require a minimum purchase of 20 to 30 litres. When a plane needs refuelling, it needs 50+ litres.
  2. Viva Energy has their own card: https://www.vivaenergy.com.au/business/aviation/aviation-fuel-card Looks like we lose another aviation-linked small business. In the case of Skyfuel, I would imagine that it is simply due to the owner reaching retirement age and converting his business to retirement funding. You can't blame him for that. I feel for his loyal employees who have enabled fuel to be available around the State, and have kept those firefighting aircraft fuelled up and ready for instant response. Will they have the yard gates locked behind them? I have it on pretty good authority that the Skyfuel depot at Bankstown is heading for shutdown due to the efforts of the airport leaseholder. There goes another of my Bankstown clients.
  3. Design decisions are made for considered reasons. Would "rubber" hoses be more or less likely to suffer damage from rubbing or vibration? Is there a fire risk that metal would provide some resistance to?
  4. I used to run the aircraft hardware sales business associated with Dent Aviation, now GB Aviation. I was there recently and there is still a good stock of hardware for sale, and probably at prices not seen for 10 years or more. If Rodney is out of stock, ask him to get things in from the wholesaler EDMO. Yes, a lot of sellers keep using the AN designations because old habits die hard. It's not wrong. The items are exactly the same, and made to the same specifications. Definitely be careful of the flaring tool as mentioned. The flare angles are different from automotive fittings. This is a diagram of Spec MS33584
  5. No openly, but did my twisted mind see some antagonism to promotion from within, coupled with years of associating with a type?
  6. I was going to go into the effect of the pressure the liquid exerts on the wall of the container due to the weight of the liquid itself, and how that pressure interacts with the atmospheric pressure from the outside. But then you'd have to take into account the resistance of the material of the container itself to deformation. Who started this journey down a rabbit hole?
  7. Skippy, AN is the old designation for what is now MS in the above material. Same dog, different collar. If you don't want Rodney to do it immediately, I'm sure he would get a round tuit for you.
  8. Ms Hudson might have been the Chief Financial Officer and hence tarred with the accountant's brush (or should that be pencil), but we don't know what battles she has fought against the leprechaun. Do we really know in whose mind the idea of slash and burn arose from? That she has been with the company for 15 years means that the Board has been standing behind her in some of these battles. Let's not condemn her before she has the chance to act. Remember that a CEO is not the owner of a company, but a conduit through which the workings of the company is poured onto the boardroom table.
  9. Skippy, Are the dimensions used in your plans metric or imperial. If they are imperial, then you will be using MS parts. Why not go down to GB Aviation at Camden ( used to be Dent Aviation) and ask Rodney to flare your tubing for you. Or got to Delta and ask Derek to do it.
  10. This is an extreme version Skippy, Onetrack is talking about vapour pressure the pressure of the vapor resulting from evaporation of a liquid (or solid) above a sample of the liquid. What KGWilson indicates is that the greater the space above the surface ofthe liquid, the more that can evaporate from the liquid and squeeze between the usual molecules making up fresh air. So, it you restrict that free-air volume, you will restrict the degree of vapour pressure heating will allow. This video is not quite an example of vapour pressure, but sort of explains it.
  11. It's probably trifling, but isn't it important to know how much fuel you actually put into a tank, especially if you are not going "full tanks". Four litres is only a tad under 3 kgs, by every gram counts. By the way, if you need to refuel at The Event, I will have a ladder, earthing straps, grounding rod and a Mister Funnel available. You supply the grunt to lift the fuel container.
  12. That was just to show where residences and hangars would go. Werriberri Creek has a very large catchment area upstream from the airfield, and the whole area is subject to intense summer thunderstorms from the southwest and Tasman Lows from the southeast.
  13. Werriberri Creek, whose valley floor The Oaks strip occupies, drains a vast area, making where the strip is located susceptible to flooding. I don't know how it faired in 2022 when the rest of the Nepean/Hawkesbury system was swamped, but there is great potential for flooding that would prohibit the erection of any buildings. I have had a quick chat to the bloke who said he was the developer. It seems that idea is to make it an airpark with dwellings built on the high ground on the western side of the strip and to have hangars built downhill, closer to the strip. That's is very similar to the development that has taken place along Sydney's waterways. This image shows the ridge line to the west of the strip.
  14. As much as I trade with Bunnings, I also accept that stuff at Bunnings is often not up to long life. The reviews of one that they sell all say the same thing - Don't buy it. Better to go to specialist 4WD retailers. Same price, better quality.
  15. The Oaks is a private airport.
  16. I had to post this here and not in the usual place because it is important; OFFICIAL: I have had it confirmed that a financial member of Recreational Aviation Australia, holding a current pilot's certificate issued by RAA, flying an aircraft registered with RAA DEFINITELY MEETS THE EVENT CONDITION THAT ARTHUR BUTLER AVIATION MUSEUM INCORPORATED REQUIRES ENTRANTS TO BE INSURED TO COVER ALL RISKS ASSOCIATED WITH PARTICIPATION IN THE EVENT. Signed: Mark Adams Display Organizer Arthur Butler Aviation Museum Inc. 1 May 2023 I believe that there is a lot of chatter about this matter on various FaceBook pages. I would ask those of you who access those pages to publish this information.

  17. I did speak to a bloke who said he was the "developer", not the owner. Maybe. Perhaps. A possibility.
  18. I hate websites that try to promote a development like this and use images of places elsewhere
  19. There is no argument that what you have quoted are the criteria and your own comments are valid. My source of annoyance is that CASA is ignoring this" I have never, even before the diagnosis, suffered from moderate to severe excessive daytime sleepiness. The reason I was sent to a specialist was simply because of my BMI being above the level set in the AusRoad criteria. According to this calculator https://www.betterhealth.vic.gov.au/tools/body-mass-index-calculator-for-adult , for my height - 178 cm - I should weigh 75 kg. I'd have to drink muddy water to cast a shadow. However, since 2017 when I started to need a specialist's report to pass my AusRoad medical, I have never been failed. Further, I have to pass a higher standard to hold a public passenger vehicle driver's authority, which I do. This is all on the basis of the specialist's report. Regarding the value of BMI as a diagnostic tool, The BMI was introduced in the early 19th century by a Belgian named Lambert Adolphe Jacques Quetelet. He was a mathematician, not a physician. He produced the formula to give a quick and easy way to measure the degree of obesity of the general population to assist the government in allocating resources. In other words, it is a 200-year-old hack. He said said explicitly that it could not and should not be used to indicate the level of fatness in an individual. There is no physiological reason to square a person's height (Quetelet had to square the height to get a formula that matched the overall data. If you can't fix the data, rig the formula!). Moreover, it ignores waist size, which is a clear indicator of obesity level. This article gives reasons to debunk BMI as a diagnostic tool. https://www.npr.org/templates/story/story.php?storyId=106268439#:~:text=The BMI was introduced in,the government in allocating resources. Here's an irony. This year, as I have said, my GP completed both my AusRoad medical report and Basic Class 2 report at the same time. In fact, since the Basic Class 2 report is more detailed, he completed that form and simply copied results onto the AusRoad report. Then I stuffed it up with the driver's licence mob and they said that I had not used the correct form. We agreed that I would send the Basic Class 2 report to them as it was not convenient for me to go to Sydney just to get the correct form completed. They quite happily have accepted that report and renewed my licence and authority. Now that I've got all wound up, I might take advantage of what KRviator has quoted and fire it back at CASA with a 'Pauline". In the end, if I have to pay a DAME for a review of my Basic Class 2 status, I might as well fork out the $250 and join RAA, although at the moment I have access to a VH- aircraft at a reasonable hourly rate.
  20. Most GPs don't "manage" chronic conditions themselves. They send you to a specialist. If you think about it, that is a sensible way to do things. Your LAME, L2 doesn't do the calibration certification for your altimeter. It's sent to an instrument maker who is a specialist. Same for your avionics. However, since 2017, when Transport for NSW began asking for reports on my sleep apnoea, the same Respiratory Specialist has been "managing" my condition. That management consists of an annual download of the data from my CPAP machine and a quick look at it. Last time I got chipped for not using the machine every night, but since I wasn't driving buses, I was let off. So what makes CASA think that a DAME, who doesn't know me, nor has never been involved in my diagnosis nor reviews is "managing" my condition?
  21. They did say to go to a DAME and get passed by that doctor. Then they provided a link so I could find a DAME locally. It was really good. I got a response of 404. I did finally get onto a list of DAMEs. Typical of the assistant CASA gives, the list is alphabetical by surname, with no ability to search by location. So one wastes more time scrolling through the names of doctors from Longford in Middlesex to deepest, darkest Africa. to find one within reasonable proximity. I bet when I make the appointment and hand over the Basic Class 2 medical and the Respiratory Specialist's report, I'll be out of the DAME's office before the door I came in by has had a chance to close. At least the GP who did the original examination combined it with my driver's medical and only charged me for one examination.
  22. If it stops, the hydrogen in the fuel tank will keep you up.
  23. Yes. I recall the discussion. But how does CASA justify denying a medical clearance that they claim is based on a medical standard that allows me to drive a fully loaded B-Double down Parramatta Road in peak hour, yet I am not allowed to fly a 1200 kg four-seater aeroplane (basic C-172) in Day VMC? Did I mention that the same NHVR medical report allows me to retain my Public Passenger Vehicle Driver Authority? Which means that I can drive a bendy bus full of primary school-aged children all over Sydney, and even from Sydney to Canberra so that they can visit the Seat of Government. I haven't looked at the way to appeal, but since the name of the highly qualified medico who knocked me back is Obaid Soomro, I don't think an appeal would have a snowflake's hope in Hell of succeeding. To quote from the email: you have a disqualifying condition prescribed in subregulation 67.263(2) of the Civil Aviation Safety Regulations 1998 (CASR). Or in other words:
  24. What a crock! CASA makes a big thing of making the medical standard for recreational pilots equal to those for drivers of heavy vehicles. Last month I had my medical for my vehicle driver's licence, and at the same time, examining the same decrepit body, the doctor completed the CASA medical report. For several years I have been using a CPAP machine for sleep apnoea. Each year I am assessed by a sleep disorder specialist as part of the driver's medical. Therefore the Transport mob is happy to allow me to drive a juggernaut through Sydney during peak hour. They will also let me drive a bus, fully loaded with school children all over Australia. But CASA won't let me fly a light aircraft over the Outback. Here's what they said: Specifically, you: · do not meet the RAMPC criteria due to sleep apnoea. The following outlines the reason why this condition/history is considered to have an impact on a pilot’s ability to fly safely and therefore precludes the issue of a RAMPC: · Respiratory physician has found you as meeting conditional licence for AMS commercial standards. Although the applicable standard for RAMPC is AMS private standards; for sleep apnoea the criteria to hold an unconditional private licence is the same as that of unconditional commercial medical standard. The condition on my driver's licence is that I have to control my sleep apnoea through the use of a CPAP machine. For your information, my Respiratory Physician told me that if you are over about 50 years of age, and snore, have a high BMI, you have sleep apnoea. It's just a natural aging of the throat muscles.
