had reply from CEO, yes its happening

feels we should all pay our way but doesnt think councils should charge fees?????

no deal with avdata just AAA, 340 members, website wont allow members identities to be seen for privacy

Says tight rules on what released data to be used for

re cta deal, 75% of 1400 members surveyed supported cta access

fees issue has been discussed at 20 meetings/events and supported

Id suggest this is a process, no info will be released until Sept next yr

-alter privacy policy

-Let is run for 12 months 

-Release information with full membership approval in writing - everyone agreed at renewal

I agree, all the talk of RAA medical arrangements and RAA maintenance for either CTA or higher MTOW is wishful thinking.

In which case why would you move to RAA with a VH reg aircraft? Cheaper to stay where they are.

Building RAA numbers via this path is wishful thinking by RAA. In which case don't trade off few advantages RAA has.

Contrary to AOPA thoughts, RAA has these different requirements because of less risk due to lower weight, lower stall and only 1 PAX

Mentioned before however the breakage of Jabiru flywheel bolts was maybe linked to larger starter. Methods to overcome cold start problems could exacerbate the issue

LiFe batteries likely have the ability to spin things faster  - a good thing - however it can increase loads on flywheel attachment

CAE for this reason changed the attachment design to overcome this. 

Its maybe why Jabiru and others wont back the use of these batteries...…...until they rebadge one for sale, then they will be OK

Heard today that this was apparently a forced landing after engine failure

Pilot and PAX were/are badly injured.

Well written but a couple of key changes may negate the argument put forward.

Has anyone indicated CTA access or heavier aircraft will be allowed into RAA with reduced maintenance and no medical for these endorsed pilots?

If this isn't the case why would large numbers of GA aircraft move to RAA? Would be cheaper and easier to stay where they are.

The same airport operators have last year increased hanger land rents by 100%, also renegotiated leases to allow this to continue annually if they see fit.

Justification is extending runways for RPL and emergency helo operations bases.

If councils don't charge fees currently, they soon will with RAA help

Ground there is pretty rough, but road (a bad one) close,

other accident, Foxbat?? wasn't that far away Id think

This time of year the machine likely working and a low orbit over equipment common. Also can be very dusty

Id guess all the low slow and steep traps exist

An AF gauge means little if the fuel distribution isnt even

your only looking at the average and could easily have one of more cylinders running very lean

Even fuel distribution

EGT are how you measure it - one per cylinder

I have flown  - some 100hrs and no difference

Been fighting this uneven EGT, as have others, through three different engines and 500+ hrs

things run more even with heated air on

Havent really tried but just using air from inside cowl might work

Im convinced its ram and swirl which changes as velocity changes through intake system - in which case every build will be quite possibly different

Changed from NACA to side duct and achieved nothing

No idea really but would make more sense than conspiracies.

Reckon RAA and others should stay concerned about their own businesses rather than what others do or don't have

He doesn't want reduced medical for RPL (or RPL at all Id guess) as its a threat to RAA as a whole - keeping RAA viable is his job. He probably shouldn't have been asked for opinion.

A fair portion of the AGM was members talking about PPL medical issues

Not sure what they were expecting RAA to do?

Likely RAA will be trying to get medical relaxation for CTA and or MTOW increase pilots, it looks like they will need Class 2 at present

The energy needed to move the water would require several power stations on the way - the resultant water, then too expensive 

Its a nice idea but not deliverable

Its a self reporting system, they will publish the account presented.

Might be delayed but better than it was

The Camit system with second case drain at the back and separator gets oil usage back to near nil.

I think you are right, trying to vent and drain back down a small dipstick tube is asking too much

Overfilling for sure sees excess oil spat out and leads to overheating too. Id think many Jabiru dont hold the listed oil volume either at the max sustainable level.

without backups yes and Ipads do fall over in hot conditions

A D180 or Ipad for non essential info will be less weight than a six pack

Mostly people set up minimum backups and a glass screen for the rest - be surprised if its a weight issue unless you look a t double screens, twin radios, etc etc

Theres been several catch can ideas, some just a bottle located along top of duct, Jabiru now have square thing on top of dipstick and yes CAE had a more thorough solution which drained back into extra case vent at top back of engine. It was developed to customer demand but I don't recall Ian wanting to do it.

Do they? Jetting should be altered to fix that. Good numbers on where EGT should be to avoid lean running

What if some cylinders running rich and others lean, single AFR isn't going to help.

Even out the egt, then AFR and mixture control would be helpful

Jabiru run a std Ryco panel filter. All air, heated or not, goes through it.

Bad weather isn't where they are often used Id guess but plenty of icing conditions.

A possible reason why Jabiru have return system is the very small oil volumes.

An engine could use up to 80+ ml/hr and only ~ 3000ml total.

Link this to some older worn engines which can use more and you could end up with problems.

There are ways to adjust mixture in flight, use carb heat or fit leaning device and then various carb options

The problem is the unevenness of the distribution. Some cylinders are on high EGT limits and some too low

Being able to control mixture doesn't help if spread is too big

When I first raised this was told "you have too much info, just confusing yourself" They sell this D180 as an option now

There are now several satellite networks like US owned GPS.

Now have GPS, GLONASS (Russian), Gallileo (EU) and BD3 (Chinese) working, US no longer has control over this tech. BUT not sure how many retail products can use these as much of the end products originated in US. Some phones do use first two.

Bottom line is US fiddling with the GPS network isn't likely to help them as much as it once did. As a result accuracies and inbuilt errors are being dialled back.

Can always fall over but if your device is watching several networks theres no problem. Pretty serious redundancy and reliability upgrade for end users.

Australia should have a error correction (WAAS style system) soon giving very accurate data in handheld devices, like cm accuracy.

Wonder when CASA and TSO devices will catch up?

Jab engines can be made to run cool, its been proven. Not easy though and as its presented in factory aircraft is pretty poor and variable.

Its EGT and fuel/air distribution that's the bear. It was ignored for many years and only fairly recently with multi channel monitoring been seen for how bad it is.
