    The SE2 ADSB transmits at 1090 Mhz. This is the same as all ADSB broadcasts from every aircraft. Airservices has had the capability of receiving and displaying this information for years. It transmits a squawk code of 1200 which is in a different downlink code to that coming from a transponder which ATC recognises as coming from an EC device and it cannot be interrogated. ATC had the ability to filter these out which probably was the case but the software has now been modified so EC devices are displayed on the screen differently. It would have been pretty stupid to filter EC broadcasts out as you can imagine what the investigators would put in their report if there was a fatal accident because they had filtered out the broadcast from a mid air collision where one aircraft had a transponder & the other had an EC device. The transmit power from the SE2 is 20 watts which is line of sight so they should see you at least 20NM away if you are high enough and where you position the unit is not shielded by any part of the aircraft. I am pretty sure ATC everywhere can see EC broadcasts. It must display the callsign as when ATC saw me he called me "Romeo 8664" to confirm visibility and should also display GPS location & altitude. I'll ask the Controller I know what detail they see next time I see him.

    No mention of any radio calls made from either aircraft.

    Yesterday was hot and I decided to go for an early morning flight. For me that means about 9am before I get going. I decided to head South from South Grafton around the back of Coffs close to CTR & check my visibility with the SE2 with the Tower. I set Coramba as a Waypoint which is 8 NM from the Tower & called 2 NM North at 2,500 feet. I was invisible on radar & ADSB as there are hills between me at that height & the tower. Once South of Coramba I could see the Airport & ATC called & said he had me on his display. I was within 500 metres of the zone boundary & climbed to 3500 feet to get over the ridge to my next waypoint of Bellingen. I called at 11NM from Bellingen & gave a position report. I got affirm & G'day. It's good to know you can be seen & identified. SE2 squawks 1200 but can't be interrogated. It also broadcasts your Rego so they don't need to interrogate you anyway by providing a code & then requesting an Ident which they then have to key into the system. So from a workload perspective ADSB reduces that load from ATC. Once it is in universal use they won't need to provide squawk codes or request idents at all but I suspect that is a fair way off yet. It was pretty hot by the time i got home. My maximum altitude was 5000 feet at about 10.15 am & the OAT was 29.5 deg.

    It took about 6 weeks at the beginning of the scheme so they have got the process sorted just before it ends. That probably means there are not many applications coming at present. The announcement of the finish date may see a flurry of new applications.

    Well, No. It has been proven in many studies that the addition of fluoride to the drinking water is beneficial to dental health. Dental carries has been on the decline since the 1960s. It has increased temporarily in different decades. It increased in the early 2000s but decreased again after 2010 to the level it was before 2000.

    Conspiracy theorists grew like topsy during the pandemic and most were adamant supporters of the biggest one of all, Trump. We have one on the airfield and he is an instructor. Even when confronted with verifiable facts these individuals are completely unmoved. Something in their brain has switched and a dogmatic unmovable attitude has set in. It is pretty sad really and often they alienate themselves from others they have known for a long time.

    Expulsion is the most severe punishment for any individual from an Association. In NSW incorporated associations must have the full process specified in their constitution. Most state the committee must act on any complaint about a member and may expel the member for a number of specified reasons. But the person expelled must be given the right to appeal the decision (within a defined period) which must be held at a General meeting of all members. The decision is only upheld if a simple majority of members present vote in favour by secret ballot. Of course if the person expelled does not appeal the decision, no meeting is required & the expulsion is final. If the expulsion was for something like misappropriation of funds and there is no dispute, it is unlikely the person expelled will publish his side of events.

    The last Datsuns were produced in 1986 when the name was dropped in favour of the brand owner, Nissan so anything available for a Datsun will be after market with unknown quality.

    10 years later and what has happened? Nothing. CASA directors come and go and the ingrained toxic culture remains to continue to serve its own ends and fail the pilots of Australia from the very top down. Politicians of all persuasions have gone in to bat for sectors within the Aviation community and numerous enquiries have achieved nothing. CASA's motto of "wer'e not happy till you're not happy" is as strong today as it always has been. The only way to sort it out in my opinion would be to sack the lot and start afresh with the only condition being if you were previously employed by CASA that would disqualify you from applying for any role in the new organisation. Utopia though only exists as a TV series.

    I don't think much thought was given to it at all. As far as discounts go it is the most pathetic I've seen. When it was first proposed inflation was very low but fees kept on increasing at a greater rate. In 2009 full membership was $160.00. Last year that had increased to $275.00. It was $250.00 from 2019 - 2021 so there was no hedging against inflation if you paid 3 years in advance. Now with inflation at around 8% a 3 year up front payment may net you 6-9% plus the 1.75% discount. It's a gamble though with odds probably about as good as pokies.

    Yep guaranteed to be a Trump disciple as well.

    Lilienthal is known as "The father of Modern Hang Gliding" . There were many other pioneers in the 19th century, Percy Pilcher is one I remember but Lilienthals design and detailed documentation of his 1500 odd flights was second to none. Why they did not get a hang glider expert pilot to provide some initial instruction I don't know. Some of the semi rigid hang gliders when I was flying them in the mid/late 70s had parallel bars and moving fore/aft provided pitch control plus weight shift to the side with legs for roll. Of course the Rogallo design (originally developed as a re-entry wing for space craft that didn't succeed) evolved into the modern hang gliders of today as well as Trikes with the pilot (or fuselage) in a harness attached to the CofG.

    I think the answer is "It depends". If you have a private ALA it is unregulated so there is no defined pattern unless you define it. The company should have defined approach and departure procedures for its pads. These are not controlled by anyone other than the owner and the airspace is uncontrolled.

    "The ATSB's review said both aircraft had collision avoidance systems installed but they were not fully integrated and did not provide visual information to the pilots". Was that TCAS or ADSB? An audible warning through the headset is going to be harder to ignore than any visual warning and what is actually meant by "Not fully integrated". The FR 24 data gives appropriate info but can be up to 5 minutes old before you see it on screen. The same goes for data through Ozrunways or Avplan as it has to transmit through the cellular phone system. Only ADSB in/out in the aircraft is in real time to the second. A real life example is a mate in the Outback Air Race noticed an aircraft on a converging path with his aircraft on his Avplan display and he called up centre about it. Their response was "It's OK he's already gone past".

    Terminate all the shields (earth) back to the radio earth at the radio and a single earth wire from there to the earth bus. The radio aerial is connected via a BNC connector at the radio which includes the earth shield. Do not earth the shields anywhere else on the aircraft or you will get earth loop hum or worse. If you use a tuned whip aerial the coax earth will be connected to the ground plane. In a metal aircraft that is the skin. Check wiring diagrams if you are using a dipole ground plane.

    I'm pretty sure that was what happened to the Motobatt that failed. It It had lasted 5 years though & started the engine fine when really cold. It was 20 AH with 320 CCA as I recall.

    I have not checked any of the issues you mention. All I wanted was a battery at the time and it was all they had. The $130.00 was cheaper than getting the instructor back. If it dies I will let this forum know. The alternator has a maximum output of 17Amps but I don't know what the rectifier/regulator allows to the battery but my guess is more than 6.6 amps after starting to replenish the capacity lost in starting. Most RA aircraft and motorbikes use AGM batteries & they seem to perform well in starting situations.

    A lot of them don't have to use Avgas. During the debate in the US there was a study done & they found over 80% of the US fleet of piston powered aircraft could run on unleaded fuel. Most don't because of ignorance or availability. Now with the Gami approval hopefully that will change. It needs to here as well

    I recently did my BFR. Got the aircraft out & the battery was dead & instructor waiting. I could not jump start it, wouldn't even turn over so I went to the local battery shop & asked for a replacement for what I brought in. I got a Ritar RT12220 22 AH general purpose battery designed for UPS/EPS high discharge and recharge use with a 6-8 year design life in float service for $130.00. Weighs 5.6KGs. Spins the 3300A over flat out. I have no idea how long it will last but it was better to part with $130.00 at the time than pay for a BFR twice. There is no quoted CCA value but it states the monthly self discharge rate is less than 3% at 25 deg C.

    My battery was nearly 5 years old by the time I got the aircraft flying. I just stuck it on trickle charge every couple of months. It wasn't regular as I'd forget but it still lasted about 4 years or more once flying.

    In that case if there is any space forward of the firewall, that is the best place for it. A simple fibreglass box attached to the firewall, foam padding on all sides with a top bungee strap to stop it moving. Best position for all heavy cables Solenoid, starter, engine earth, regulator, main fuse etc. Another good idea is to install an Anderson plug on the fuselage close to the battery so that you can easily jump start from any other vehicle if the battery is to flat to turn the engine over. This my battery installation on the firewall. The battery is 6KGs

    There are a number of reasons why the seatbelt anchor was torn out including previous stresses from earlier issues with the aircraft. Back in 2016 I was one of the first on the scene when a J230 went in under power in a cow paddock just short of Runway 08 at South Grafton. There was extensive damage and the entire front of the aircraft was torn off and partially went under the fuselage. The pilot and passenger were left in their seats looking out at a bunch of startled cattle. Injuries were a cut on the head of one and a sore knee from the other. Jabirus are tough and the passenger compartment is amazingly strong. Photo of this one below In a lot of other aircraft GA & RA the occupants would not be here to tell the tale.

    I couldn't give a rats if I can't be seen of FR24 or Flightaware. So long as I can see ADSB out aircraft in my vicinity when flying & any with ADSB In can see me that's all that matters.
