T510

That is some scary footage. Props to the paraglider pilot for deploying her reserve so quickly, lucky the plane only hit her chute and not her.

There is a lot of things wrong with the current drone regulations in Australia, the above is one of them Hopefully there will be some significant changes in not too distant future to bring Australia's once world leading regulations up to date

My last parts inquiry with Floods took ~7 days for a response, was quietly surprised with the pricing too, ended up being the cheapest price I got on some 582 carb manifolds

Hope that stall speed is a typo or that's a very narrow flight envelope 😉

This is a good one Skip, you certainly have me scratching my head. Where does the return enter the header tank? if it is in the top it could be aerating the fuel, I had a fuel aeration issues on one of my race cars that was fixed by returning in to the bottom of the surge tank instead of the top. If it where my aircraft the next steps I would take is to confirm the fuel pressure and flow readings are accurate. I would be calibrating the fuel pressure gauge using a syringe with the required weights and using a graduated cylinder to calibrate the fuel flow sensors. I would also confirm the one way valve in the pump bypass is operating as intended.

Skip, I spent years in R&D, testing and manufacturing as a small engine specialist. I enjoy this type of challenge. If the one way valve on the bypass is not closing fully you could be getting reverse flow through the bypass circuit. Is your fuel pressure sensor inline or dead head style? Have you tried cracking the fitting on the fuel pressure sensor when it is pressurised (preferably without getting a face full of fuel) to see if there is air in the line? If there is, the air being compressible, could give you false fuel pressure readings. As the pressure sensor is the highest point in the fuel system if I understand your description correctly, any air bubbles could be expected to rise to the pressure sensor. How are the internal fuel tank pickups connected to the external fuel lines?

From your first post it sounds like the issues are not necessarily related. First issue being the low fuel pressure warning which triggers you switching the boost pump on which solves the low fuel pressure issue. The second issue is a decrease in indicated fuel flow rate when the boost pump is activated. Do you use the boost pump in any other flight modes, ie landing or take off, or do you only use the boost pump when you get the low fuel pressure warning? If you don't get the low fuel pressure warning and switch the boost pump on do you still get the reduced indicated fuel flow? Does the boost pump bypass have a one way valve? If it does could this be staying partially open allowing the pump to recirculate fuel?

Are you sure the fuel pressure sensor is accurate? I spent ages chasing a boost issue on an engine only to find out the boost pressure sensor was randomly giving an incorrect reading. 90% of the time it worked fine, the other 10% it was borked. Only managed to find it by data logging the sensor output

Just because you believe it to be the truth does not make it so. The useful information you provide is negated when you go off on your delusional political tangent talking about Trumps "Dealings and Putin Loving" You are the reason the conversation took this path, no one else mentioned American politics

It's not having a go at you, it's calling you out for your hypocritical response when you regularly make irrelevant political comments. It's pretty offensive that you disrespect the people involved in this horrible accident by using it to project your personal opinion of Trump then make excuses about it being an example as if that makes it alright. Have some respect for the people directly affected by this tragedy

It's pretty sad that a post about a tragic accident is twisted to an irrelevant political commentary. It detracts from the forum and is disrespectful to the pilots who died, their family and friends left behind and the people injured on the ground.

I tend to disagree with that quote, Airservices is already working on their version of a solution (right or wrong) to incorporate unmanned aircraft in to civilian airspace. From what I have seen they are leaning heavily towards the "positive separation" model as opposed to the "detect and avoid" Airservices have released all the abbreviations, FIMS (Flight Information Management System) is being developed at the moment to tie their UTM (UAS (Uncrewed Aerial System) Traffic Management)system into their "OneSky". Which to quote Airservices is "the most complex transformation of air traffic management in Australian aviation history. It’s a partnership between Airservices and the Department of Defence, replacing existing air traffic management systems with an advanced integrated system known as the Civil Military Air Traffic Management System (CMATS)" Surely all these changes will result in a smooth integration of uncrewed and crewed aircraft with no teething problems or confusion🙄

I don't know why they didn't just buy one of the conversion kits available to convert aircraft to unmanned

Didn't stop the 17yo with a shotgun at Avalon

Used to get the same when I lived near Moorabbin. I'd get some funny looks when I asked if they had noticed the airport was there before they moved in to the area
