Geoff_H Posted January 9 Posted January 9 3 minutes ago, FlyingVizsla said: The CAO 95-10 Exemption (2024) does not specify engines, only MTOW and wing loading. This is reflected in the RAAus Technical Manual 4.3, December 2024, RAAus sets no design criteria. Builders are free to design as they wish and build using any materials they wish, but they add the words "low momentum". Multi engine, even jet engines can be 95-10, and they have been registered as such with RAAus. The challenge is keeping the weight below 300kg. There are now allowances for parachutes (20kg) and floats (55kg), taking the max for a water landing craft to 355kg. All other categories registrable under RAAus are single engine only. CASA have inserted "Note A microlight aeroplane is not a Part 103 aircraft." in CAO 95-10 Section 5.1 definitions. Then why can't a Cri Cri be an RAA listed aircraft?

FlyingVizsla Posted January 9 Posted January 9 3 minutes ago, Geoff_H said: Then why can't a Cri Cri be an RAA listed aircraft? It fits the 95-10 category for MTOW, but fails the wing loading. CAO 95-10 Section 5.1 (b) has a wing loading not exceeding 30 kilograms per square metre at its take‑off weight. The Columbian Cri-Cri specs say Wing loading 55kg. However, there was some discussion about extending and widening the wing to reduce the wing loading. Someone was trying that, I have not heard how he went.
Geoff_H Posted January 9 Posted January 9 I believe that is where the requirements are not as good as they could be. Maybe 30kg for an untested aircraft but use a landing speed as an override if below a certain amount. The problem is that a person unable to get a GA PPL cannot fly a Cri Cri but it is one of the lightest aircraft around.
Geoff_H Posted January 9 Posted January 9 I believe that a fibreglass wing tip could solve the wing loading issue. My back of a napkin (always the best calcs as per Rudd internet design), say that wingtip extensions could even make it a powered glider. I have been making a Composite Cri Cri similar aircraft but have abandoned it owing to the significant design and testing issues that have extended the design and build process to a time when I will run out of Medical. My DAME recons i have another 5 years before I will be too old to pass.
facthunter Posted January 9 Posted January 9 Where is there an AGE limit on being fit and healthy, stated.? Nev
Geoff_H Posted January 9 Posted January 9 Every year now its a stress and ultrasound on my heart then a full blood test. As we get older, in spite of fitness, our heart gets more dodgy, usually heart valve. In her opinion, she is my GP and DAME I will pass for another 5 years, I am 77 now.
facthunter Posted January 9 Posted January 9 Stress ECG,s are risky, More so when you get older. Her assessment is re you.. Get a second opinion on the risks of the Bruces protocol stress ECG.. Being around is important as well as keeping a licence. It gives NO assurance you won't have a Heart attack and can even promote one about 10 days later. Nev
Geoff_H Posted January 9 Posted January 9 Three times weekly i exercise and my heart rate gets to between 170 and 190. On the stress test I get to around 165 before I say quit, usually due to lack of breathing. I have been doing the exercise for just under 30 years. Don't expect it will kill me soon, I have been told of how to stop if I get certain issues.
Geoff_H Posted January 10 Posted January 10 The way I understand it is that a stress test that takes you to a higher level that your heart usually reaches is very dangerous. And often kills you. At my test I am doing less than usual. I.have had an angiography and it showed 3 not the usual 2 arteries going to my heart and little blockage. Probably why I am doing so well at present. However does not mean I won't drop dead tomorrow.
facthunter Posted January 10 Posted January 10 You only have to get to 150 but there is a duration 9 minutes? requirement as well.. This Test has been been contested for many years. as dangerous and ineffective at predicting heart attacks. I've been investigating it since the 70s' and Many Cardiologists agree. It's not just Me on a crusade.. nev 1
Geoff_H Posted January 10 Posted January 10 I agree. But CASA requires the actual data from the test, not just a cardiologist saying I am OK. If I don't do the test I don't have a Class 2. They sent me a very dirty email telling me that it must be sent to them on time. The cardiologist said I was OK, it was not until the actual numbers were sent that they approved my Class 2 for another year. It does not worry me as I get greater stress 3 times a week for 45 minutes, maybe I should worry, I am addicted to endorphins.

Geoff_H Posted January 10 Posted January 10 That is too "exciting " for me. It is one of those "rather be on the ground wishing I was in the air thing". Night VMC (years ago) is "IFR in the dark". That was "exciting", well heavy adrenalin.

What makes it more poignant is that they require that you sign a waiver, that now worries me. Another flying risk. Although I have been doing them annually for nearly 20 years.

Geoff_H Posted January 10 Posted January 10 I suppose that the question now is does a stress test, an ultrasound on the heart at maximum stress and blood test each year reduce the risk of me having a medical episode in the air?
facthunter Posted January 10 Posted January 10 The ultrasound anytime is OK No risk with that. Arrythmia will stop you suddenly. People who do these tests aren't going to be TOO critical of them. They get well Paid for doing them. Some make a living doing nothing else.' Good, and Timely medication is what keeps you alive, as well as surgery., where Indicated. Multiple bypass pilots have continued to fly since about 1988.. Tests are just tests with stress You went OK THAT time. They Don't FIX anything .It's like revving a car engine UP. Next time you do it a conrod may let Go, You may also suffer a stroke. 2 types. Blockage and haemorrhagic in the Brain. and blood clots in various parts of your body. Drink enough WATER. Live a healthy lifestyle IF you want to keep on flying . Don't carry excess fat in the wrong places . Keep your blood pressure under control.. (medication) Avoid stress if you can. Nev

You're looking at it back to front. Of course there is a tiny risk, of course people still die immediately after checks and always did. However the diagnostics pick up many in the community with major problems and take those people of the roads and out of the air. The self reported system is problematic with a few too may cases of a crash on the road or from the air and everyone saying "Nooooooooo" we never even knew he had a bad heart." You will have seen the reassurances of "virtually no pilots hjave died from heart attacks in the air". Digital, which records every vaccination you've ever had, every test, every medication you've been put on, will tell you with just a couple of clicks on the phone when you last had a tetanus injection. Authorities can see blood thinners etc too.
facthunter Posted January 10 Posted January 10 They don't HAVE to get put off the roads They SHOULD be treated. Many do and are living Normal lives. You have the wrong take on it. DID you read my post about 3 back where I covered this. OPEN heart surgery pilots have gotten back in the Air with 1 st ATPL level. We don't HAVE to live in the DARK ages Medically. Nev 1
