    I read a very good statement, by a guy writing about his SF260, one of the sexiest single engine aircraft out there. He said the nose wheel is there for one reason, to attach a tow bar to! What he meant was, often pilots will raise the nose off only on rotation, at times almost wheelbarrowing and on landing, will dump the nose down almost immediately after touch down. Nose gears are sometimes not that strong and are already having to carry the engine weight.
    Personally, I like to treat my nose wheel gently. On take off, as soon as the speed is alive, I come back on the stick, and you need a lot of rearward stick, because elevator not very effective at this stage. I select and hold, the climb attitude. This allows for a very smooth lift off and the aircraft also lifts off when it’s ready to fly. Can be tricky because you need to co-ordinate reducing back stick, as the speed increase, to hold the climb attitude constant. You don’t want to over-rotate.

    On landing, same thing, After touch down, I hold the nose wheel off as long as elevator authority make it possible. Yes, don’t let it slam down. This allows good aerodynamic braking and reduces stress on the nose gear. Of course, this is NOT done in a X-wind landing, get that nose gear down ASAP in a X-wind. Anyhow, this works well in my Gazelle and let’s the stronger main gear do most of the heavy lift work. 

     

    I do a similar thing after being taught and shown what can happen if you relax that back pressure on landing.  The machine can easily want to fly again and a "bounce" can start.

    Keeping that nose up also means you are basically keeping the aircraft in a stall - so assisting in preventing it from wanting to fly again - keeping its wheels on the ground.  

    It's also really handy on gravel runways to try and prevent your prop from throwing crap up.

  2. Agreed Skip. 
     

    The only thing I’m very cautious of is handing over too much power to government and relinquishing our freedoms. 
     

    Remember, we we still a democratic country, and yes I want leadership, but with checks and balances.  
     

    And just to restate. I’m not anti nor pro vax. I’m just a normal dude.

    I settled on Johns Hopkins University of Medicine because it is collecting and distributing accurate data very day of every month until the end of this epidemic.

    That gives a steady stream of results - what has actually happened day by day.

    A lot of people are posting information used to make a case one way or the other, sometimes honestly, sometimes not, but most of it is contaminated by what is collected, or the standard of medical treatment provided which varies from outstanding treatment of the patient resulting in a survival not expected in any data to offloading the body from the hospital ER for burning.

    The Victorian DHHS has been adding to their daily bulletins total people hospitalised, those in ICU, those on Ventilators and those who died. From the hospitalised total they are quoting the number of people who are double vaccinated, and single vaccinated. Those numbers have been hovering around zero for a few days, but I haven't followed them becaise we know the problem area with big numbers - thousands - at risk are the unvaccinated, and they are a finite number of Victoria's population, and reducing every day as they get vaccinated.


    Yep. There a few sources I trust, that’s for sure.  A bunch i don’t as it becomes very clear of the agenda.  
     

    It’s amazing how polarising it is.  It’s the new religion and I’ve seen friendships end over it because one person has a different view.  
     

    We just need to all respect the next persons right to believe in what is best for them.  We don’t tell people which mythical creatures that apparently lives in the sky, they should believe in. 
     

    we respect their faith and smile and say, good on you. 
     

    If we don’t hang on to that mutual respect we are doomed, and sadly the fear mongering from the main media is appalling. But it sells I guess.

    Actually I have come to understand something from your passing-on of those ... little anecdotes.

    But it ain't to do with epidemiology of any kind.

      

    Good luck with your flying.  Seeya.


    And what might that be mate?  I’m not allowed to think for myself.  You dont think I deserve that respect. I’ve probably lost more people I know from Covid now than most of you.

     

    SEEYA!!

  5. Just to be clear - I don't have a view either way. I am certainly no expert.  Just looking at the data and trying to understand it.

     

    But understand this.....

     

    2 weeks ago, my friend (double vaccinated) caught covid.  Gave it to his mother (double vaccinated) She died. (over 70)


    Today, one of my flying buddies tells me his wife (Double Vaxed) is now in hospital fighting for her life. (over 70)

     

    Like i said... Just trying to make sense of the data without influence from so called Drs and Scientists who are paid for the pleasure.

    The actual point is to reduce the COVID-19 virus to one where it is not termed a "pandemic". Perhaps you need to check up on the definition of "pandemic", which is exactly what this virus is, and what it has been declared in every country in the world.

    I get that. But that was not my question. 
     

    Let’s look at a scenario….

     

    they don’t want to let unvaccinated in a pub. Ok Goodo. Let’s roll with that. 
     

    99 vaccinated people in there, and the next guy walks in also vaccinated but has Covid. 
     

    what was the point of keeping the unvaccinated out?  Was there any benefit to that?  
     

    Now I can already hear people say “it reduces the chance.”  Ok. Reduce but not eliminate so we can pretty much guarantee one of the vaxed will have it (it’s delta after all) so the actual level of chance is unimportant. 
     

    So again. What was the benefit of keeping the unvaxed out if the vaxed can still spread it?  Simple question.  

    • Agree 1
  7. I guess the first question is. If I’m in my 40s. What is more of a risk?  My flying me aircraft or dying of Covid?

     

    Of course the government does not want me getting it and passing it on to someone who is 70.  Sure. But the vaccine does not prevent that, so what is the actual point then?

  8. I’m not saying we do nothing. Don’t get me wrong.  Of course Covid is a problem but I think the response needs to match the threats. 
     

    These images attached are again from the governments own site and data.  Make of it what you will. But let’s discuss. I would like to hear what we all think of these graphs.

    That's not a PITA,  this is a PITA:

    "I've seen full-grown men I work with just break down crying. That's a daily occurrence. We're already at the brink and I just don't know how 'opening up' is going to go. I'm so nervous about it. When will it end? It's just relentless". Belinda*, Sydney-based COVID ward nurse

    "They say we’re coping now, but you only have to speak to the staff day to day, week to week, they’re suffering in silence. Just ask the ambos, ask the people in ICU, they will tell you we’re on the brink" - Greg*, 40-year veteran nurse, Victoria

    "I've been called a 'COVID bitch' on my way home from work, people say to me: 'How do you sleep at night with your dirty COVID money?'. It's exhausting to hide part of yourself so that you can feel safe, even though you are helping keep people safe" Denise*, COVID vaccine nurse

    Denmark's Covid -19 cum. death rate is 44.85 per 100,000 population - 13 times the rate of Australia

    Australia's cum.is 4.2 per 100,000 population

    Source: Johns Hopkins University of Medicine 9/9/21

     

    If the Denmark performance was applied to Australia's population we would have 11,450 dead instead of 1066.

    And Denmark is opening up now with Covid-12's exponential spread. vs Australia opening up maybe late October on our rate per 100,000 at that time.

    Someone experienced at exponential equations might be able to predict the comparison by Christmas.

     

     

     

     

    Let’s get some perspective lads. This straight from the ABS.  link below for you.  
     

    IN AUSTRALIA 

    • There were 5,043 deaths from respiratory diseases between January and May 2021. NOT INCLUDING COVID.  

    There were 766 deaths due to influenza and pneumonia recorded between January and May 2021. NOT INCLUDING COVID. 

     

    • 20,143 deaths from cancer occurred between January and May 2021.

    Why are Covid deaths more important?

  11. Again... just thinking out loud, and like a good aviation student, thinking about the what ifs.....


    So here is the scene....  

    100 people allowed in the pub.  Stats say... Less likely to get it and pass it on.  So what... 1 in 100 chance?  Cool... so now we have one person in the room with the other 99 that is infected with Covid.  Then what?  The other 99 now also have the possibility of getting it, and now taking it elsewhere!

    Do we know if this is a REAL possibility - Israel will say it is.  Just doesn't make sense to me.  But maybe I overthink things too much!

    Vaccinated people are less likely to be infected, less likely to pass it on, less likely to end up in hospital, less likely to die.

     

    Same logic: What is the point of changing my oil, if engines can still fail? In fact, statistics show that most engines that fail had had their oil changed.

     

    Less likely is very different to can't!

    If you are sitting at the pub across the table from someone with it for 3 hours, I am pretty sure we know the outcome!

    About half way down.

     

    “All of these individuals had underlying health conditions, three were fully vaccinated,” deputy chief health officer Marianne Gale said.

     

    “Three had (received) one dose of a Covid vaccine, and three were unvaccinated.

    So today, I went out to the hangar (read, I walked out my laundry door and past my clothes line to get there....🙃) to do a bit of troubleshooting to see if I could work out what happened yesterday.

     

    I drained 55L of fuel from the right tank, had a look at the vent line (clear) and also a look at the CAV-110 fuel drain that showed it had a few small bits of accumulated debris in its' ports which led me to break out the borescope to try to verify the fuel pickup was unobstructed. 

    I couldn't get a good view of the pickup, simply due to the angle and the borescope not being able to bend sufficiently - though I did get it stuck on the fuel sender for several minutes while I contemplated both how long it would take me to remove the tank + borescope from the wing to unjam it and how long Vans would take to get a new tank access plate gasket to me in the post....

    After getting it sorted, I added 5L of the removed fuel and pulled her out to do some ground runs, and she started and idled smoothly on the right tank as she has for the last few years, ran up to full power and held it beautifully, but lo and behold, after getting everything up to temperature, she's stumbling and pig-rootin just like she did yesterday, however, using the diaphragm override on the Rotec, I could recover the RPM each time it faltered. Not well enough to hold a specific RPM, but enough to keep me airborne if needed. On shutdown to add some more fuel, I left the Dynon's powered and fuel pressure climbed from the normal 5PSI to well over 20PSI in around 4 minutes - the highest I can ever recall seeing it and well above the capacity of the electric boost pump, suggesting the fuel is indeed boiling in the lines.

     

    She wouldn't restart and idle, yet alone run smoothly, after adding the extra fuel so I had to tow her to the Avgas bowser, but I refueled the right side with Avgas, added a few litres to the left to top it off and will repeat the ground runs tomorrow to see if she is more stable with Avgas instead of 98, but for now, I think @BirdDog wins the choccy frog. I use the same pump at the same servo every time, so all I can put it down to, is having different blends (summer v winter?!?) of 98RON in the left & right tanks though I thought that was more a diesel thing, a bit of Googling suggests it happens with unleaded as well.

     

    Why do I win the Chocy Frog?
