    Iridium plugs

    jetjr replied to jetjr's topic in Jabiru

    A key problem overriding all this is the uneven distribution of fuel or spread of egt and cht At best a user has to limit and fuel for the hottest egt cylinder, often meaning others way below limits and on danger side for rich running Without this sorted or at least monitored well, tuning is simply picking a best compromise

    Often consultants are used for outside review and provide skills or experience thw business cannot afford to keep on staff OR they cannot maintain in place The more staff cost, the more attractive consultants are. You can also stop using them quickly unlike permanent staff

    Iridium plugs

    Iridiums were supplied as std on CAE engines. Some low grade coils Jabiru supply have problems with them I have run for several hundred hours and have had good results

    Yep, and now he probably doesn't have to handle all the daily stuff like accidents and questions/arguments with members.

    they are pretty good for wind rating ......until you add doors or end walls Current makers give 5 yr warranty of covering and theres some good stuff but also rubbish. I do have an application for one if theres one for sale.

    Key staff member wants to move on, he does, new plan doesnt stack up and he remains on as consultant. Pretty standard across many industries. Gives the organisation time to fill the role and develop proper replacement. Possibly a good outcome for members, if the new job at CASA had worked out we would be way worse off. No way CASA would allow him to assist RAA. Remember the whole MARAP process relies on someone like Darrin being CASA delegate (or some terminology) doesn't it? Without that person there are plenty who cant modify AT ALL. For most its only major mods where this is required.

    Reckon theres more secrets and code here than in RAA.... HR issues, until they are resolved shouldn't be made public although these events do appear odd.

    All councils have changes however currently they are keen on developing aviation and the loss (and return) of air shows in last decade has been a wake up I don't think the aerodrome has ever flooded - kind of why its built where it is. Cant vouch for the Skypark though and we see councils building freeboard on top of freeboard based on Brisbane and other experiences. Insurance drives everything

    Narromine is in the middle of heated debate about a flood levee. Id say that's why the sensitivity. Skypark is the councils own subdivision so extra butt protection needed. The entire town is considered flood prone to a 1 in 100 yr event, last seen in 1955. That is before Burrendong dam constructed. In recent years they have forced to build new houses above this level, most of the town is not. These heights are ~ 1.0m above maximum flood height with some margin OVER the 1:100 level, I think so the chances of the aerodrome flooding are small. It is located in one of the highest areas locally. If a levee is supported, it currently is not by many of the community, the skypark will be protected by it, however it seems likely the raised floor height will remain as insurers indicated "levees can fail" Its a great place and aerodrome and currently local flyers becoming active which is good to see.

    The collection of landing fees etc is a net COST on small council airfield operators. Further building belief that aerodromes are loosing money. It costs more to administer than they recover. RAA not sharing members data is simply the law, CASA violate this law with complete disregard You can always register voluntarily with AVDATA?

    What about FRP dust and such from building or odd modification Sanding and grinding would be the worst

    Id reckon good quality dry break connectors would cost more than the rest of the transfer system outlined here. Also many aircraft fuel lines and tank ports are tiny therefore slow to transfer 20L. Im still a bit windy about using electric pumps and clip on leads etc etc around petrol. Also keep an eye on current drawn.

    Some of NSW has had well below average rainfall for seven years, its not just a dry spell. Andrews work whilst interesting wasn't admired by all and unlikely to be transferable to drier areas where these problems predominate. As for Kidmans book somehow you are saying all farmers should emulate him?? how?
  14. jetjr
    Drought sourced stock tend to be near worthless - Ill bet those prices you claim aren't for hungry garden variety cattle. Farming for sure is a gamble, I don't think any business is financially prepared for a 1:100yr event. If these landowners have to leave, it will have big impacts on the economy as a whole, Like it or not much of our countries wealth is predominantly from miners and farmers.

    I would be interested to know a big picture of current rural equity now vs 40-50 yrs ago Suggest lenders have a much tighter grip on farms and infrastructure now than then. When things are tight is when these costs really become apparent.

    97% of nsw is drought declared, this takes a serious lack of rain not just a little dry spell The scale of the problem prevents all the simplistic solutions offered from working People have sold moved and shot stock already, whats left are those which might bring income for the next few years. If they die and theres no income for several years, these people and the thousands of businesses they support could end up welfare of some sort Livestock are the visual focus but winter cropping in some areas has missed a start on the back of a few tough years too. A very small few farmers are wealthy enough to operate as indicated here, id suggest those with no debt or a farm gifted might. See a whole lot more of under used million dollar assetts around cities.

    Where do you agist sheep when most of the state is in similar situation? Do you reckon theres paddocks just sitting there waiting or would their owners be using them or perhaps grazed out by millions of starving wildlife. How do you pay to get them there and presumably back? At what point do you do it? Ship livestock around much and you will be broke in even a moderate year. Six months ago some areas were sitting with low but close to median rainfall and usually get an autumn break. Didn't happen. Something very wrong with your simplification on breeding and management looking at grass height and breeding or not. It isn't an annual exercise and if your not looking longer term you had better stick to something else. Diligent bank shareholders should be excited with all the equity their companies are developing in rural Australia right now.

    RAA I don't think has any distinction between builder and owner, not true for Experimental GA though. Certainly know plenty who trained in 19 they bought. Theres plenty of factory assist builds which are 19 and are free of manufacturer LSA limitations too

    Have to say I was surprised it contained mercury - very dangerous and expensive stuff Most dynamic balancing media Ive seen is ceramic beads but that's in different applications

    Jabiru stock and sell pieces of firesleeve

    Tyre slime and balance beads work pretty well to balance BUT in aircraft tyres they go from stopped to full speed too fast for it to work as its …….slimey Mercury should move fast and the balancing action does work in constantly rotating things

    Uncertainty, either real or percieved is a killer of confidence With a regulator in place who could make a widely impacting decision. One that could jeaparidise a personal five or even six figure investment, takes either high level of optimisim or stupidity.

    I have a bracket made to bolt onto oil pump housing on Jab, sensor fits centre, other unit with light pickup sits on flat side behind. It "sees" past it to base of prop. Havent drilled hols in cowl for it but not a big deal - All in concept at this point :) Guy from Smart aviation was worried about heat and it would get quite hot there especially upon landing

    without too much effort the PB3 can be mounted to work in flight.

    or could it be that more qualified people work in less controlled environments? Statistics s can be painted many ways. Only way your assumption could be at all relevant is if the different IQ people were doing the SAME task, then outcomes compared
