Hi everyone. I have a doubt regarding the privileges of a RPL over RPC. If one was to have a RPL with CASA, and decided not to keep his RAAus membership, would he be limited to flying ony GA registered aircraft, or would he be able to fly RAAus as well as a GA registered aircraft?

Thanks for your input :)

Hi, the cost of the Dynon Servos in Australia is under 1200 AUD each and the control panel is under 1000 AUD and it is compatible with the the Dynon Skyview Packages in the Jabiru. So why is Jabiru charging 8,500 AUD for Dynon 2 axis autopilot, when the cost of upgrading it yourself is likely to be under 3,500 AUD. I am sure I am missing something. Please could someone enlighten me. Thanks 🙂

... these airplanes are well behaved and subtle

This is exactly what I am expecting to hear, from those who have a real life experience with the J160. It is almost impossible to stall a plane, as long as you - don't pull on the stick! The single most important maneuver that causes the airplane to stall (IMO) is pulling back on the stick, no matter what the configuration. If unsure what to do, just release the back pressure on the stick, and most certified, "well behaved" planes will fly themselves out of the stall. I just wanted to confirm that the J160 will not bite, and behave as expected.

RFguy: Imagine you are established on finals / base to final turn at 65 KIAS, with approx 10 knots headwind. You forgot to put on the flaps because of turbulence / crosswind / distraction (pilot error / human factor) / stuck flaps due to mechanical fault. Suddenly the wind drops, or you encounter a wind shear and the IAS drops to 55 KIAS. The stall speed is 55 KCAS = 58 KIAS in J160. I am concerned it would be enough to stall the plane or drop a wing in a turn while you are too low to recover. It can also happen soon after take off. while you are 50 to 100 feet up in the air. Another possibility is being caught by turbulence / wind shear when making an emergency landing on top of trees in a forest in case of engine failure, and you forgot to put on the flaps for the fear of the inevitable!

Hi Skippy, nice to hear from someone at The Oaks! I did my flying lessons in a Jab LSA up there. In fact I was contemplating between going with the J170 up at The Oaks or the J160 at Albion Park, given the scary figures for stall speed for the J160. I was flying the Pipistrel Alpha Trainer at Albion Park, which is a fantastic little airplane.  Although the Jabs had got a bad rap, for their engine failures, statistically, the commonest cause of fatal accidents is pilot error. And given the really low number of fatalities in a Jab, I would not wish to be in anything other than a Jab, if my fan was going to stop! I agree that the numbers look scary though in a J160, hence the reason for this post, to get some real life figures for the J160 and what others think of the numbers.

Thanks guys. All your replies are so informative and helpful. It all makes sense. Just don't fly it below 70 knots, no steep turns below 80 knots, and limiting to 30' bank angle if flying between 70 to 80 knots, as in base to final or crosswind turn, I guess should be OK.

Hi everyone

I was just doing a desktop comparison between the Jabiru J160 and J170. One of the things that got my attention was the difference in stall speeds between the 2 aircrafts. The clean stall speed of J160 is 55KCAS (58KIAS), whereas that of the J170 is 45 KCAS. A difference of 10 knots!!

Just wondering if this raises any eyebrows or is it a cause for concern, as it appears to have a very low threshold or safety margin, before it can enter a stall or spin, especially if one happens to do a steep turn and if the speed was to bleed off rapidly and unintentionally. 

I would like to know of any real life experience or any thoughts on this high stall speed in a J160?

Thanks guys. It's no point then in trying for a RPL if all you you intend to do is fly an RA Aus registered aircraft, now that the RAMPC (RA Medical Practitioner Certificate) is being phased out, as per CASA.

Hi, I just  checked the CASA website and the fee for CASA RPL appears to be only $50, compared to $246 for RA-Aus. Am I missing something? If it's only $50, is it possible to fly an RA-Aus registered aircraft with just a current RPL? Thanks for your input. 

Hi everyone, I recently had an opportunity of flying a Jabiru J 160 at my local flying school. Having done most of my training in a Jabiru LSA, I found the flight controls on a J 160 way too heavy. Is this because of the larger control surfaces such as the rudder, elevator and ailerons in the J 160 compared to the LSA? Or is it due to the heavy wing loading on the J 160 as it is a much heavier aircraft with the same wings of an LSA? Has anyone else experienced the difference in the control pressures required while flying these 2 different models? Has anyone flown the Pipistrel Alpha Trainer, after flying the Jabiru LSA or J 160, and noted any similarities or differences in the control pressures between the J 160, LSA and the Pipistrel Alpha trainer? Thanks ?

No worries. Just shoot. I started off my training in UK with some 45 hours in a AX2000 cyclone microlight leading to my 1st solo. I started out roughly your age, but had to stop for 5 years, then went back into it with additional 10 hours or so in a Jabiru, at The Oaks, under the expert guidance of John (Snr FI) & Dave (CFI), before taking off to the skies on my own once again. In the meantime I did about half a dozen dual hrs in a Cessna 152 and was on my way to a PPL, but decided to go the recreational route as it was much more economical. You can always upgrade to a RPL - PPL - CPL - Airline Pilot, with all your hours being counted, if you decided to go all the way. There are a lot of experts here, and I am sure you will be rightly guided. Cheers :)

Ok. Got it , so to become the native of a particular country, one needs to kill and murder the inhabitants and plunder the land. And once they have conquered the land by deception or using power against someone who is weak and vulnerable, then they become the original inhabitants .

According to your logic - if countries like India & China, which have the largest armies, decide to conquer Australia in a World War 3, then everyone in India / China who moves to Australia will become natives of Australia, and will no more be immigrants! Lucky, the Indians and Chinese do not follow your logic .

Sorry its taken a bit to get back to this, been a bit busy.This is a short video of a recent approach where I had a large air speed variation in turbulence on final. An uneasy feeling when your airspeed suddenly drops but fortunately returns as quickly as it dropped off. I think it was just a result of the turbulence from the tree line as I could see no other real reason for it but have a look anyway there is slow motion at the end to see if there was anything unusual and also because my fat head was bobbing back and forth due to the rough air, but as noted I couldn't see anything.

Thanks for looking.

 

The aboriginals came from elsewhere too you know so that makes them immigrants too doesnt it....how far do you want to go back. Is it only good enough for 200 years or 20,000 years

If we don't fix it soon, EVERYBODY will suffer, that includes Gays, and every other minority group.Minority groups need to clearly understand that they get privileges and exceptions because we are a prosperous society, if that prosperity suffers so do they, we are all in this together.

 

Immigration will fix all of this. I read it in the paper.

Hi Romeo Juliet Whiskey, I had been watching your youtube videos over the last week and think they are really wonderful and very educational. They are in high quality HD with an excellent sound system. I love watching them in my free time and intend to watch the full series. I was pleasantly surprised and feel privileged having received your response. I just want a cheap set up, hence was looking into using my existing action camera from China along with a Chinese audio recorder, which is similar to the Sony one you have but very basic and generic. I was hoping to catch the cabin sound via the existing headset mic into which we speak, which feeds into the radio anyways. If I do not get the cabin sounds using the radio attachment as expected, then alternately I might just add a 3.5mm splitter to the mic input on the audio device and feed 1 socket of the splitter into the radio and the other socket into the stand alone mic, and see if I can capture both (radio + cabin) sounds onto the audio recorder simultaneously if required. It might save me from having 2 different audio files to synchronize, if this arrangement works! Besides, my action camera has no input for an external microphone.

I have not flown for 9 months as I was too busy with work, but will be flying soon once my RAA membership is reactivated. I usually fly out from The Oaks, using the school aircraft from John. It is Dave's flying school, and they have a sister school at Wollongong. Cheers :)

Hi Bruce, Just go into settings / menu and see that you have not set it to Auto Power-Off or Limit Video Recording duration. My Qpix has such a setting so quite possible that GoPro also has a similar setting. If yes, then disable Auto Power-Off or Video Recording duration. Hope this helps Cheers :)

I have decided to use a $25 dictaphone and tuck the mic into the headset earpiece if it fits, or alternately attach it to the radio using a 3.5mm to 6.35mm adapter and a 6.35mm splitter. Eventually I will dub it onto the video. I have a Qpix action camera, so no external mic facility.

I think you may be interested in having a look at some of the gadgets that I have mentioned below.

Hi guys. I am wondering what strategies do you folks follow for audio video recording in a Jabiru cockpt. I am thinking of putting an action camera to record the flight but it does not have an excellent audio recording facility. Hence I was planning to record the cockpit sound / voice separately through the headset and dub the video later on with the voice recording.

Please could you let me know if you have any other better ideas that are cheap to implement, or how to go about doing voice recording using the headset attachments and what kind of adapters I may need. It is a Jabiru LSA that I am intending to fly and record.

Thanks :)

May be use a dash cam

Yes. No wonder I don't see much of a drop in revs on doing the mag checks. When I switch the first one off, there is almost no difference and the needle stays put. On switching the second one off there is a very slight deflection of the needle to the left, but not what I can call significant. It has had me wondering if the mags are working fine or not. But the reassurance of the engine revving alright only on one magneto at a time during the checks is enough to satisfy me that the mag check is ok.

Why? Is it because the ailerons on a 55 are that good or the rudder is crap?

On a positive note, if the ailerons got jammed for any reason you know that it would not make a huge difference as long as the rudder was functional.

Gosh No! Would not want to risk it lest the mag fails and the otherwise smooth running engine shuts down last moment. And if the mag was to fail, it could fail on the finals anyways, hence what would be the benefit of that check? Once you are up there you will have to come down at some point. It is possible to avoid take-off but not possible to avoid landing with a failed mag.
