When I was programming my new transponder late last year, I spoke to the Airservices ADS-B guru regarding the R8519 vs 198519 and his advice was to use the full registration - exactly as would appear on your flight notification. Thats what I have now and have not had an issue so far.

From the RAAus Ops Manual section 2.07:

To use your Holden analogy, I am not a mechanic. But if I buy a Commodore and it needs work, I then take it to a bloke who has been trained by Holden in their vehicles. IF he makes a mistake that disables the brakes under certain conditions and kills my missus & kids, why should he not be liable for it? IT isn't that old mate misused the seat, but even if he had to use it in anger, it would have been rendered useless, as shown in the following paragraph...MB knew there was a risk of the pilot's parachute failing to deploy if a particular nut & bolt combination were too tight, and they knew this 20 years ago, but apparently failed to warn the RAF, so not only did the seat malfunction (with the safety pin being described as "effectively useless" by the Coroner), but, having been inadvertently ejected, a survivable accident was rendered a fatal one by the failure of a piece of equipment that MB knew could be defective.

Just to clarify the above, the GPS position source must* be TSO'd to C145/146 standards. Most all TSO C129 GPS' such as the non-WAAS G430/G530, KLN89/90/94 series and others are not good enough for ADS-B out down here. So we need at least a G430W if you want a screen, or a FreeFlight1201 if you want a blind ADS-B position source. *'Some' C129 GPS' are apparently OK but I havent been able to find exactly which ones they are.

ASA have come out and say the Dynon transponder is fine for ADS-B/Mode-S so I wouldn't worry too much about that. I have one in my RV and don't have th slightest concern about some overzealous CAsA muppet making an issue of it during a ramp check.

Why go down this path? Because Dynon have a $700 solution to getting true 1090 ADS-B in a lot of aircraft, using a GPS that has been tested and proven (by the British CAA, IIRC) to provide better performance than an uber-expensive Garmin that is TSO'd. Because the U.S. FAA have decreed that so long as the GPS position source meets the performance standards of the relevant TSO, than it is acceptable to use it for ADS-B out in experimental aircraft. And this from the country that invented the bloody TSO's! Yet CAsA, as always, are 20 years behind. If they were really serious about us wanting ADS-B, they would permit the Dynon GPS-2020 and Garmin GPS-20A in experimental aircraft - under the VFR initially, for testing if necessary - but nooooo, they mandate we have to spend the better part of $5,000 for a FreeFlight 1201 or $10K+ if we want a TSO-145/6 position source with a screen on it! Look at the ADS-B vs the SSR coverage maps and then consider how much further you have the safety net of flight following, or directed safety alerts because you are transmitting your call sign and position to ATC. EDIT: HERE is a link to th UK official testing of Dynon/Garmin non-certified GPS's with the comment essentially being "they should be permitted and installation encourages forthwith".

I was up there Monday and someone did the same thing - with no one else in the circuit! By comparison, my calls were 10NM East inbound, Joining crosswind behind a Mooney on downwind, and turning base behind the Mooney. I don't get these "Every leg, every time" calls, or the teaching behind them...

I reckon it could be done in a -9. Seems to be a bit of room in mine, especually if you remove one of the seat backs.

I carry an escape hammer in my RV-9A for exactly this reason. You can't always rely on a friendly cow cocky passing by to get you out of the wreckage of your pride and joy. The loss of 1lb payload, I can bear!

There's a catch with most RV's out there whereby your outboard seatbelt can be tangled around the rudder cable causing restricted travel. An again with the rudder cable, if you're not careful during installation and install the flap pushrods bolt backwards with the nut on the outboard end, it can snag The cable so when you drop the flaps, you get full rudder too!

Primary radar is what people usually think of when you mention 'radar'. The antenna sends out a radio wave and the metal structure of the aircraft reflects some of this energy back to the antenna that is then available for display on the scope of the controller. No altitude info, not very useful. Following on fromthis, we have "SSR" or Secondary Surveillance Radar, that sends out a pulse that is recieved by your teansponder that then replies with a radio message containing your code and altitude, and if you've pressed it, the Ident beacon. This SSR has much longer range and as it has your code and altitude is what controllers predominantly use.

Still down for me a moment ago...I can't recall ever having this problem with AvTrader or the RAAus or SAAA classifieds. And I'm actually shopping too...

And, for those that haven't seen it yet, what happens when you get it wrong trying to take off again!

So far as I am aware (always happy to be proven wrong, of course) there is no separation standard on the ground, other than what is written in CAR 166: "(a) the pilot must maintain a lookout for other aircraft that are being operated on the manoeuvring area of, or in the vicinity of, the aerodrome to avoid collision; (b) the pilot must ensure that the aircraft does not cause a danger to other aircraft that are being operated on the manoeuvring area of, or in the vicinity of, the aerodrome" and CAR 168 (8): An aircraft that is about to take-off shall not attempt to do so until there is no apparent risk of collision with other aircraft.

A brand new ECI OX-340S with: 7.2:1 Pistons Dynafocal 1 mount 14mm plug bosses & automotive plugs all round Dual P-Mags Low-pressure, engine-driven fuel pump 2 hours break-in on their test cell But without a carb (Used a Rotec TBI instead) cost me $25,604 USD, a few years ago, including crating but excluding shipping when the $$ was at parity, or close enough. Shipping was another $1,000-1500, IIRC, airfreight. Then another $3,000 GST and freight forwarder charges on top of that, for close enough to $30,000 AUD. Given you're considering both a -320 and -360, don't overlook the -340 too. The weight of an O-320, but if you go standard (or high) compression pistons, throw in EI as well, you'll have the more power than your average O-360. I have 20 hours on mine now in an RV-9 and can't fault it.

In regards to Flight Following, what is the best, or preferred time, to cancel it on descent to your destination, or intermediate airport? Can we hang on to it right up to the circuit area if surveillance coverage is available?

Yes, in a 582-powered Drifter during a low-power descent that caused an engine failure and landing in a paddock. When I went back to look at the charts, I couldn't have been any more in the middle of the "Severe Icing - Any Power" regime, but until then had been told "It's a two-stroke, it can't ice"....yeeeaahhhh, right...

Because I have nothing better to do (and get bored easily), I plugged the remaining VOR coordinates into GPSVisualizer's calculator, with the range set to give the theoretical range of the BNN VOR's at 5,000 and 10,000'. Here's the result... Red are your typical ASA-owned VOR's, Oakey is green as it is DoD downed, and Avalon, Hamilton Is and Christmas Is are blue, privately-owned VOR's. Oh, and I take no responsibility if you get yourself lost using these. They're worth what you paid for it! The country-wide coverage at 5,000. And at 10,000. Victorian coverage at 5,000. And 10,000. NSW Coverage at 5,000. And at 10,000. Qld/NT Coverage at 5,000. And at 10,000.

Under the VFR (Except NVFR) GNSS can only be used to supplement other Nav techniques. Under the NVFR, you can use VFR as primary navigation for Area Navigation. CAsA instruction 80/14 chapter 5 refers. Although I have just noticed this particular instrument - though it is listed as "in force", actually expired at the end of March 2016... So you have your flight plan and nav log, with times and headings which would correspond to DR techniques and must use your ultra-precise GNSS box to supplement these techniques. You also have to positively fix your position every 30 mins when nagvigating visually. But then, AIP ENR 19.2.1 says you can use radio navigation systems (ie, TSO C129-GNSS units that meet RNAV performance requirements) or VORs, except when below 2000, when you must navigate visually, and when using radio nav aids, the position fixing times extend to 2 hours... Clear as mud?

If an instructor ever turned off the ignition (note, NOT magnetos) during a BFR in my RV he would be sporting a bloody and probably broken nose once we landed. Not every engine has magnetos, not every engine will restart when you advance the mixture - and that is assuming the student completes the activity correctly to actually get to that point without having fluffed something along the way. The PMags I installed in the -9 have an internal alternator that doesn't require ships power above approximately 900RPM, however below that speed they require an external electrical source. The Sensenich prop likewise will probably stop somewhere around best glide speed, especially with a high-compression engine (one day I'll actually test it overhead somewhere suitable). The Rotec TBI manual contains a caution that if you lean-cut the engine, it won't restart by simply readvancing the mixture. Put that together and if you fall short, or overshoot and you have an issue with the starter, or its contactor (happens often enough that it would form part of a risk assessment for the activity) and you will be having a very bad day, very quickly. There is no excuse for shutting down a perfectly good engine in the name of "training". Not at our level, anyway. Far too many pilots have died during training as compared to the real thing.

That'll teach me for posting in a hurry... My payload is actually 340 lbs, not 360. Can't seem to edit the original.

There are two RV-9A's on the register, of which one is mine - which is registered as a two seater. HOWEVER, I do not have a two adult seater. I can take (almost) full tanks solo, or one of my young blokes for a two hour local junket, but for my requirements at present, this is a perfectly acceptable compromise at present. To get the weight down, I did nothing special, other than choose a tip up canopy, lightweight Sensenich prop (lightens the bank balance too, it does!) and lithium battery, and I have a basic interior that I sewed myself. I polished the majority of the plane and used vinyl stickers on the fuselage rather than painting. I have an O-340 engine but that was chosen for the performance aspect, irrespective of the weight. My BEW is 981 Lbs, so I have 360Lbs of payload. Retired Racer is the owner of the other RV-9 and I think he has an O-233/235 donk in his, so has a substantial weight advantage over mine.

CAO95.55 permits a 650Kg MTOW for aircraft "equipped to land on water".I wonder if I could use that for the RV to gain another 50Kgs?? After all, it doesn't say you have to takeoff again after that landing.......

This is perhaps the most common comment I hear about having only the second RAAus RV-9, but for my requirements, it is still perfectly adequate. If CAsA want to ramp me, I'll even offer to provide the scales...My BEW is 445Kg, so I have 155Kg payload. Fuel fuel weighs 100Kg, so if I can lose a few more pounds myself, I can (nearly) fill the tanks. My young bloke weighs 20kg in his carseat + my approx. 75-80kg and I have 55Kg fuel, or 70Lts, still enough to go to Brisbane or Melbourne with reserves, or a 2 hour local junket. No, I'll have around $100K in it now, but I've only just installed ADS-B and bought the autopilot servos...QB fuse & wings, brand new engine, polished with vinyl stripes and an interior I sewed myself. 150% of my cost of 100K = $150K for the Pipestral. You can easily put an RV in the air for under $60K if you are willing to compromise on what you fit and accept the standard kit build times. I certainly wouldn't be burning an additional 4GPH on top of the published figures for the Rotax, I'd be lucky do be 1.5GPH over those figures, but even so, that's a cost I was willing to bear. As Vans say in their advertising, $50,000 difference in purchase price buys a lot of fuel! $6,000 for a 10" dynon screen, 1900 for the ADAHRS module, 900 for the engine module, $750 for the GPS, and $3,000 for the transponder, it is easy to run up the costs. I don't need an EFIS or Autopilot or Mode-S in the RV, but it is lighter, and provides a lot more capability. If you are going to use the speed of an aircraft, short of going to Reno, then you're going somewhere, and an autopilot and EFIS makes a lot of sense, even taking into account the costs.

True, but have you priced some of those LSA's lately? The QB kit for the Virus is well north of 100K AUD, and that's before you add $20,000 worth of avionics, shipping and GST, realistically, you would probably be approaching $150K as a completed cost, more than 50% higher than what I have in the RV, for what I see as less performance. The Virus SW also achieves its performance with an extremely high aspect ratio wing, so you need a bigger hangar for it. It's published cruise speed (100HP version) is only 147Kts at 75% power, and it can only lift 400Lbs payload (for the 1042Lb TOW version) or 650Lbs for the 1322Lb version. You can get 3 or 4 RV's into a hangar that you could probably only fit one or maaaaybe two Virus's (Virii?!?) in, and those RV's will go faster than a Virus, climb (much) better, carry 250-300lbs more than a Virus and do it while only burning 1GPH more. That being said, the Virus will lift that 600-odd Lbs while remaining within the constraints of CAO95.55. I only have 370Lbs of payload before I run into the 1320Lb limit, so a definite plus there! I have electronic ignition on mine, and I will be running mogas when I finish Phase I. I have automotive plugs in the O-340, so other than possibly oil changes (if you subscribe to a 50hour oil change in the 912) and a $6/hour fuel difference, the costs are pretty similar. I suspect insurance would also be a lot less for the RV series than a Pipestral, but that is my suspicion only, I have nothing to base that on, other than "they look pretty expensive to fix if you break it"! Notwithstanding the above - and that I have an RV so am naturally biased - the Virus SW is both an attractive looking airplane and functional, if you can afford it. But outright speed is not what I was after when I built the -9, and I definitely couldn't afford something from Pipestral, much as I tried to make the numbers work. If you are building an airplane to go far and fast, I've always felt a 914-powered LongEz or VariEz would be the perfect combination. But I can't afford one of them now either..... :-p
