It was designed for fuel to be used on Jabiru but l never got used to it. I'm used to certified. 

Certified parts are fine for certified aircraft.

 

I am one of those owner/maintainers who like to find automotive replacement parts (mainly hoses, occasionally other stuff) that meets or exceeds the OM aircraft part specifications, for a fraction of the OM cost. 

 

It should be recognised that the standards required to meet certification (parts) labours under a huge weight of history, that does not always reflect changes in technology but you will pay dearly for it anyhow.

 

Being able to find & substitute such parts, is one of the benefits/plesures that comes with owning a home built aircraft.😈

One of the forums had Garmin reps on and people asked why the G3X Touch efis was not also a IFR navigator as it has an internal WAAS GPS and fast processor;

Did it have the same GPS and firmware as their IFR navigators - yes

Was the processor fast enough to handle approach/departures - yes

Was the hardware built to the same standards as their IFR navigators - yes

Was the hardware subjected to the same testing as their IFR navigators - yes

Had Garmin ever produced IFR software that would run on the G3X Touch - crickets

What would happen to the price if Garmin submitted the paperwork to the FAA to get it approved for IFR - the price would double

 

Garmin decided that their main market for the G3X Touch was VFR flyers so did not get it approved to keep the cost down.

 

Is this grossly excessive costly approval process part of all certified avionics ?

I believe the answer is yes.

 

So you want to replace an engine oil hose.

• You contact the engine/aircraft agent/dealership (OM) - that will be $k/cm thanks.
• Hose will come with certification document(s) which you are expected to diligently file away so that you can demonstrate, to any enquiring authority, that you followed the rule book to the letter. In effect transferring lability to he hose supplier. All of this cost $$$$$ - add to that the relative (to the automotive/industrial world) slow moving item and further $$$ added.
• You find the maker of the hose and they publish specifications for it.
• You use those specifications, to find a similar (automotive/industrial) hose, that meets or exceeds the OM standard. That hose will be $k/cm divided by 10.

 

Note: all figures for illustration purpose only.

G3X also has certified version currently

I've been an A&P for 50 yrs, I A for 35yrs, and an aeronautical engineer.  I can tell you that some of the components used in some light sport aircraft are are incredibly substandard and have failed at times. I don't like a lawnmower fuel filter for my Jabiru 230D and I don't like the filter "after" the fuel flow computer, it should be before it.

Let me clarify that I want want components that at least meet certified standards,  not necessarily being legally certified. Vinyl fuel hose does not meet that condition to me.

A mention of control FEEL  with Jabiru's "Bowden" push Pull cables is worth a Mention.  Overall I think the 230 is a Pretty good Plane. IF the engine gets Hot on a hot day Increase the climb speed keeping in Mind any ground obstacles..  Nev

When i began flying recreational aircraft after many years of GA singles, I couldn't land them well either. Bouncing was common so there were plenty of go-arounds.

 

My thoughts are that 

 

1. There is much less inertia with a Jabiru or any recreation aircraft than with a C172, PA28 etc so airspeed will bleed much quicker leading to rapid altitude loss even in ground effect.

 

2. Fly the aircraft all the way to the ground. This takes practice, Flare at only a few feet from the runway. With the high wing ground effect is less noticeable that in my low wing Sierra. Don't try to recover from a bounce until you are much more proficient. Always go around.

There's some Hairy  efforts  there.  The ONE with the AIrbus A 300. The throttles didn't  respond due to wrong manipulation of the Auto's With  An Aeroformation Pilot in France. Nev
