Possibly oscar. But the numbers provide an easy "bullet' for them to fire dont they?

Crood picture I just made for you. But you can try and imagine the relative airflow in a descending turn. In this instance coming from below and left in a left turn. The right wing shows clearly, a lower angle of attack. Sorry its a dodgy pic, but hopefully it makes sense.

The lower wing in a turn has a higher angle of attack. Add to that the aileron increasing the angle of attack at the TIP of the wing as you deflect it DOWNWARDS to pick up the wing. Forget about turn radius etc. 1. In a level turn, lift MUSt be increased to remain level. 2. In a descending turn, lift MUSt be increased to keep descent rate constant 3. Lift is increased by increasing angle of attack in both 1 and 2. 4. Angle of attack is increased by increasing back pressure 5. A wing with dihedral will have a higher angle of attack on the DOWN GOING or inside wing. Thats how it works. Thats why theres a tendency for the aeroplane to right itself. Its a basic principle of stability.

Not at all Gandy. Nev made a statement that if true has lots of merit in the conversation. if there is indeed a "worse" engine out there, then I for one want to know what it is. Secondly, CASA need to explain why these "worse" engines arent being legislated 'against'. I dont want p1ssing contest either, but I would like statements like " there are worse" engines to be explained. We have a hole in our school now, that needs filling. If there is another suspect engine out there, I want to make sure we dont end up with that bugga online too:)

Nev, which engines are "worse"?

So, what is the worst of them out there? CASA quote 45 'failures in 2014..Show me ONE engine that had 46?

But surely numbers count for something. You can't say they must go after the rare engines that aren't in any numbers .

Perhaps it's the numbers? At your average bankstown or moorabin, would the " worse" engines be represented in any real " threatening numbers? ( genuine question)

I think they did, thats why it wasn't worse IMHO. One failure a week is not something they are willing to tolerate. It could work out in the ned, if it forces a fix.

I dont know how much "worse" it could get? NoteParagraph (a), together with the definition of populous area, has the effect of prohibiting Jabiru-powered aircraft from departing from or landing at various places, including but not limited to Archerfield, Bankstown and Moorabbin Airports. So No jabs ourt of several airfields. AND.... This is the 'waiver' we are expected to get students and pax to sign.. ‘I, [insert name] , PROPOSE TO TAKE A FLIGHT IN THE AIRCRAFT IDENTIFIED AS [insert registration information] (THE AIRCRAFT). I AM AWARE THAT THE CIVIL AVIATION SAFETY AUTHORITY (CASA) HAS DATA INDICATING THAT THE TYPE OF ENGINE USED IN THE AIRCRAFT HAS SUFFERED A HIGH NUMBER OF FAILURES AND RELIABILITY PROBLEMS. ‘I ACKNOWLEDGE THAT CASA HAS IMPOSED LIMITATIONS ON THE AIRCRAFT TO PROTECT PERSONS ON THE GROUND NOT ASSOCIATED WITH THE OPERATON OF THE AIRCRAFT, UNINFORMED PASSENGERS AND TRAINEE PILOTS. THOSE LIMITATIONS ALSO HELP PASSENGERS AND TRAINEE PILOTS TO MAKE AN INFORMED DECISION ABOUT WHETHER TO ACCEPT THE RISK OF FLIGHTS IN THE AIRCRAFT. ‘I NOTE CASA’S ADVICE THAT, ALTHOUGH MOST JABIRU ENGINES OPERATE NORMALLY, THERE IS AN ABNORMAL RISK THE ENGINE IN THE AIRCRAFT WILL MALFUNCTION. ‘I ACCEPT THE RISK OF BEING INJURED OR KILLED IN THE EVENT OF AN ENGINE MALFUNCTION DURING FLIGHT, NOTING THAT: ‘(A) THE AIRCRAFT MUST BE FLOWN AWAY FROM PEOPLE ON THE GROUND (AND BUILDINGS), EVEN IF THAT MEANS AN EMERGENCY LANDING AT A LOCATION THAT IS LESS SAFE FOR THAT PURPOSE; AND ‘(B) THE SAFETY OF AN EMERGENCY LANDING CANNOT BE GUARANTEED EVEN IF THERE IS A SUITABLE LANDING LOCATION. ‘I NOTE CASA’S ADVICE THAT I SHOULD NOT FLY IN THE AIRCRAFT IF I AM NOT PREPARED TO ACCEPT THE HEIGHTENED RISK INVOLVED. ‘I ACCEPT THE RISK NOTING THAT THE ENGINE MANUFACTURER IS WORKING TO IDENTIFY AND FIX THE ENGINE ISSUES AS SOON AS POSSIBLE. ‘I AM AWARE THAT CASA REQUIRES MY SIGNATURE ON THIS STATEMENT BEFORE THE FLIGHT MAY COMMENCE. ‘SIGNED: DATE: ’ I dont know about you guys, or know about "gettin that into me" but anybody who flops this in front of a student and thinks they will be still sitting in front of them in 30 seconds time, lining up for a solo flight, have rocks in the head!!!

So we are going to need to get students and pax to sign a statement saying jabs are more likely to fail, and we have to accept the extra risk? yea nah. Im cool, I wont be sending any students solo under a waiver.

That is a shame. I have senced trouble a foot out there at golbourn. You only need to read the notams regarding use Of the airfield by recreational aircraft to smell a rat. Shame, last thing we need at the moment.

Incipent spins are a required competency under the RAAus syllabus.

Settle down mate. I "heard" a school was closed down, and was asking if anybody else had heard anything. From that school are we?

One of the raa schools.

Which school at yblb got shut down recently?

Im sure he still would:)

Shouldnt that be something in the POH? If its required to keep the engine alive? Why did it take you adding extra equipment and applying your knowledge to the situation. Are you a test pilot? Are Jab paying you to 'develop methods" to ensure longer lasting engines? Feelin me?

Captain. If I hear the argument " Plenty of owners dont have trouble" again i swear im gunna jump off a bridge. So THEY BLOODY WELL SHOULD. This is a certified aeroplane engine installed in factory built aircraft. Unfortunately, plenty DONT. If that wasnt the case, we wouldn't be having this discussion, and CASA would be sharpening the knives in the back room. My comments related to an occurrence I HAD. A 3300 certainly did 'grenade" and had 6 channel monitoring while it happened, so I could see the pot go thermal nuclear. After being one for the cooler pots for the life of the engine , so yes, the monitoring did probably save a REAL engine failure as we didnt depart with the alarm bells ringing.. I apologise for the 'digs' but they are based on actual experience, not just hearsay etc.

Due to Casa?

Least he can take a pax:)

Yea. Engines fitted with 6 channel monitoring don't fAil aNd spit head bolts ... Oh ... Wait.... Yes they do.. But at least you get to watch your engine grenade is awesome 6 channel resolution...

Is that a flying school? Havnt heard of it. Ive heard of the "harden the #$@% up School" but not the saucer of milk.

I think that comment was a miss aligned back pedal that went horribly wrong for him...lol

Lol. Whoops aldo. All those years of flying . And a ga pilot to boot. I was waitin for you to add something about your years of experience. You seldom post without it;) My flying school is inside a military restricted zone, so I'm familiar with the jargon. Have been known to fly the occasional ga aircraft too.. Think I've got a cpl tossed in my flight bad somewhere too. May not compare with your years of experience, but i would be happy to teach you how to identify airspace. :)
