Well I'm definitely not going to get the audience excited... Now onto something different. I'm going to need a flight computer, if not to navigate certainly to pass the written test. I spotted the CX-3 and got excited but a friend told me 'No electronic aids during the test'. So back to the EB6. Are all brands equal? Is there good and bad or best?

I'm tired of chasing the meaning of acronyms in all this paper work the feed us. Yesterday I printed out 28 pages of acronyms and their meanings. Today I find one that's not on the list. PILOT CERTIFICATE FLIGHT TEST 9. Prior to a Student or Converting Pilot being recommended for the issue of a Pilot Certificate, they will be required to undertake a flight test with a CFI (or higher approval holder when assigned by the HFO). The Student or Converting Pilot will satisfactorily demonstrate to the CFI their competence to control the aircraft in accordance with the RAAus Syllabus of Flight Training. What is a HFO?

I'm envious. I didn't even have to build mine, only fix it and I'm still running behind. The adventure begins 🙃

I'm not training until I get my plane in the air. It'll save me at least $150 p/hr and I'm better off knowing my own plane. I was ready to go solo but I'll be a bit rusty by the time I get back.

It just shows you can't get away with doing the wrong thing up their. Out flight trainer can be sitting back at his desk keeping track. Whoever it is has had the circuit to themselves until now. Another plane has just turned onto the runway.

I just spotted one of out training aircraft doing circuits. Pretty tidy of his turns, definitely not me 😉

Today was another uncomfortably hot day. I just feel like sleeping it away but forced myself outside for a couple of hours working on the carport. I realised the other night, when I should have been sleeping, that I need to find some pipe. The proposed airstrip has a couple of natural gullies heading in from the north. If I just level out an airstrip it won't last beyond the first downpour. So when the day heated up I jumped into Tonka and cut a couple of trenches across the strip. I was going to use Zimba, the little CAT excavator but it would be slow work and I'd be in the open air, no AC. I can't get any deeper without a heavier machine or a jackhammer so I think there's going to be a lot a fill. I budgeted for my lessons and plane but it never stretched to building an airstrip so now I'm searching for abandoned pipes for drainage.

Karratha airport may have been closed due to the trajectory of Tropical Cyclone Sean.

That may be true but they might have all got the same weather report. https://youtu.be/u0QxS1GBlB4 From Karratha it headed west then south following the coast but out to sea.

The temperature is interesting. I don't know where it gets that info?

I didn't look into it at the time but my guess is that the majority were international flights perhaps diverted a little more east than usual due to weather conditions.

I doubt that. I was sitting at the computer watching them fly by.

Sure seems confusing however you approach it. One way the previous aircraft is so far beyond range it's hardly worth mentioning and the next you're setting yourself up for a nasty surprise if he chooses to taxi back up the runway. Anyway I enjoyed sitting watching as it flicked from one short informative to the next. I left it open because I want to watch more.

It looks like it's seeing aircraft over 120NM away. It could still be overlapping the range of another antenna but who'd be silly enough to install one out here?

Is it just my ignorance or do the acronyms used in aviation make reading any literature a chore. I think much of it is simply a case of laziness from the author. I found this list that printed out on twenty eight A4 pages. I don't think any normal person could memorise this list therefore it just creates delays and confusion for student and most likely experienced aviators as well.

I purchased a new Chrysler Galant 1500 in 1971. The oil filter undid itself on a couple of occasions. The most memorable was on the Mount Cotton hill climb where I spun out on my own oil. Another time was on Milton Road in Brisbane while racing some hoon who was obviously driving dangerously. it was not an uncommon occurrence on race vehicles in the 70’s and 80’s so clamping them became a habit.

The filter looks a bit grubby but that's because I gave everything a good coat of ACF50 to help with things like that hose clamp on the filter. It mightn't look good but everything has an oily film that will probably give it a bit of corrosion protection.

Recently purchased from Bert Flood. I'll take a look in the morning. Just took a look at the invoice. I got two x 825016. Perhaps it's just the extra clearance I've given it with the remodeled exhaust pipe on No.2. I shouldn't have to move the pipe next oil change.

I just heard an aircraft go overhead, a rare occasion here so Mrs M said go and see how many are up there. The antenna display says 24 aircraft. I know nothing about this thing but it must cover quite an area. We usually see 4-6 on the monitor.

Any magnetic plug will collect fine particles over time and I have no idea how long its been there. The paper from the oil filter was clean, not a fragment of metal or anything else I could see. Some of these engines had a faulty propeller shaft that would shed metal. This one is not amongst those serial numbers so I'm happy to wait for the next inspection after its done some work. I didn't fit a washer, nor did I over tighten it.

Ok I've looked at that. The reason they strip is that it's a lousy Torx with no grip. When you tap the Torx key in it deepens to grooves and gives you a bit better chance of loosening it. It's a bit furry but looks worse than it really is, nothing like 3mm which is the limit. There are no lumpy bits. It was just like a paste so I'm not concerned about that. We'll see next time 😉 And guys, I'd appreciate all those instructions before I fit the exhaust 🤣

I'll get to it shortly. 43° forecast today so I'm busy getting some welding done on the carport before I reach meltdown. I've been looking at the Rotax site and most seem to fit a coper washer even though it's not allowed. The plug is wired anyway so even if it was to loosen it would never come undone.

https://decalinchemicals.com/products/decalin-runup-fuel-additive/ Decalin RunUp is approved for use with the new 100VLL (Very Low Lead) fuel announced by the FAA on Special Airworthiness Bulletin NE-11-55.

Yes obviously a problem. http://www.rotax-owner.com/all-videos/expanded-video-instructions/295-magplug I'll sort it out tomorrow.
