How has COVID 19 affected your flying or intended flying
aro replied to SSCBD's topic in AUS/NZ General Discussion
The best way to protect front line people is to avoid getting infected. Preventing medical staff from being infected is possible (China eventually succeeded, most other countries have not) but seems to require biological warfare levels of PPE which we don't have enough of. The ongoing impact of this virus in countries with large outbreaks is going to be PTSD in the medical staff. They are going to work every day and seeing patient after patient die. They see their colleagues get infected and die. Every day they wonder whether it is going to happen to them. Yesterday there was a report of the suicide of an ER doctor in New York. Protecting front line people requires preventing infections. -

They haven't banned flying, they have banned leaving the premises where you reside (in Victoria). If you can fly without leaving the premises (hover a helicopter in your backyard perhaps?) go for it. More seriously, if pilots go flying you can guarantee that some will gather in groups at the airport for a chat - particularly as pilots seem to be one of the groups most likely to downplay the impact of the virus. The same thing applies to golfers, and most other activities where people say they can do it while distancing - you can be sure people will end up gathering in groups. Hopefully these restrictions will only be in place for another 3-4 weeks before they are relaxed a bit. -
The government has said they expect the borders to be closed until the end of the year. I expect it will be even longer - as you say, 12-18 months. Perhaps some international travel would be allowed with a compulsory quarantine period on return, but who would want to go anyway? The disease will be causing problems around the world for at least that long. New Zealand is the one bright spot, they are attacking the virus even more than we are so we may be able to travel there if we can control it here. The outside chance is the UK. (Personal opinion only - experts probably disagree.) They perhaps have the ability to control their borders enough that with a strict enough and long enough lockdown they might be able to control it, even though their current situation is very bad. Perth-London would be the go then I think. If there is any international travel in the next 2-3 years I expect fares to be very expensive.

How has COVID 19 affected your flying or intended flying

We can see the statistics on deaths, we hear personal accounts from ER doctors in Italy, the UK, New York, we can see bodies being buried in a mass grave on Hart Island in New York. These articles denying the death rate are approaching flat earth or fake moon landing levels of ridiculousness. We can clearly see the evidence that they are wrong. -

Sweden looks to be middle of the pack in terms of number of deaths, but a few weeks behind other countries. Come back in 3-4 weeks and look at their statistics. -

The worst infection and death rates are countries that initially did not take it seriously. It is still very early days. It is only a month since we started to see significant numbers of deaths outside China, and it's a slow disease - for those who die its maybe 4 or 5 weeks from infection to death. We are very lucky in Australia having been able to see what happens in other countries in time to prepare ourselves and take precautions. I am hopeful that we will find better ways to treat it over the next few months - in the meantime we need to minimize the number of infections. Poorer countries are likely to be very badly affected. -

They were made by Mark Levine, chair of the New York City Council health committee: [MEDIA=twitter]1247155043171741696[/MEDIA] They generated a lot of controversy, he has walked back the suggestion of using public parks, saying it was just a contingency: [MEDIA=twitter]1247257389776109573[/MEDIA] He now says that if temporary burials are required they will be on Hart Island. -

Death counts are likely to be more indicative, although they lag by at least 2-3 weeks. New York is saying they may need to temporarily bury bodies in mass graves in public parks because they cannot handle the current numbers. Even then the numbers may be under counted. In New York they say that around 200 people per day are dying at home. Normally it is around 20. These people are not included in the count because they were never diagnosed with COVID-19. -

We can look at other countries to see what happens if the spread is not controlled. Cases (roughly) increase by a factor of 10 every 2 weeks. So 4000 cases could be 40,000 in 2 weeks, 400,000 in 4 weeks, 4 million in 6 weeks. And with the incubation period you can expect the number of cases to increase for another week or 2 after spread is controlled, so whatever number you have then you can multiply by 5-10 if you do a good job of control. Look at Italy, they went from only a few cases, no problem, to overwhelmed in a few weeks. The USA is going through the same thing. There will be a massive number of deaths there. They are talking about 100,000 deaths but I have no idea what they think they can do to keep the number that low. We are hopefully locking things down early enough to avoid that scenario. -
30 degrees angle of bank is not a rate 1 turn, unless you are doing somewhere in excess of 200 knots. A rate 1 turn is 180 degrees per minute, not a specific angle of bank. It's easy to say that you should just follow your training, but these accidents tend to happen when things happen differently to what you did in training. Maybe a few things combine, e.g. a tailwind on base, a slower aircraft in front of you and a heavier load and further aft c.g. than you are used to. You delay turning final a few seconds to increase the separation with the aircraft in front, then you need a tighter turn because of the tailwind but you remember your instructor warning about steep turns in the circuit. Some subtle rudder pressure brings the nose around a bit quicker, some back pressure to avoid catching up with the slow guy ahead and ... oops!

Maybe CASA don't know their own rules? the holder has a valid flight review for the rating during the period ending CASR 61.745 (1A) (b) if: (i) the holder already has a valid flight review for the rating (the previous flight review) when the holder successfully completes the flight review; and (ii) the validity of the previous flight review is due to expire within 3 months after the holder successfully completes the flight review; at the end of the 24th month after the validity of the previous flight review expires. Also, from the CASA website: Flight reviews How long is my flight review valid for? ... if you complete a flight review any time in the three months before it is due, your original renewal month remains unchanged. This means your review remains valid, even if you do it early. For example, if you have a private IFR rating flight review and it is due to expire at the end of April 2018 but you undertake it in February 2018, your next private IFR rating flight review will be due at the end of April 2020.

By my reading, the instructor is required to send the notification to CASA, with 50 penalty unit/strict liability offence if they do not. I think the pilot is legal to fly as soon as the flight review is completed, if CASA don't receive the notification it's the instructor's problem. It would probably be wise for the instructor to make sure it is done.
-
For a GA flight review, if you complete a flight review in the 3 months before the previous flight review expires the new review is valid for 24 months after the expiry of the previous review. So to answer the original question, yes, for a GA review that expires in March if you do one now the expiry date will be 24 months from March. I don't know how or if that translates to RAA flight reviews.

What Numbers are used for Marginal VMC, or Special VFR?
aro replied to poteroo's topic in Student Pilot & Further Learning
There is obviously a big difference between SVFR when the cloud clearance does not meet the rules for the particular airspace, and SVFR when horizontal visibility doesn't meet VFR minimums. -
Avplan do use ADSB paints, sourced from one of the internet sites I think. Their traffic seems to be much more comprehensive than OzRunways as a result. Perhaps being denied OzRunways traffic prompted them to get traffic from a much better source? Here are some screen samples from both, showing the same areas within a few minutes of each other: Avplan OzRunways Avplan also source traffic from a glider network which is nice: OzRunways: The only additional traffic Avplan would be likely to get from OzRunways is non-ADSB OzRunways users, and OzRunways traffic outside the coverage of the ground ADSB network.

What Numbers are used for Marginal VMC, or Special VFR?
aro replied to poteroo's topic in Student Pilot & Further Learning
In Australia, Special VFR is 1600m visibility and clear of cloud. However, it's not ATC's job to call a stop to it. Visibility is the pilot's responsibility. ATC's job is to make sure you don't run into IFR or other special VFR aircraft. -

If those numbers are correct I'm not surprised they were audited for quality -
Accuracy of the "1 in 60" rule for navigation.
aro replied to APenNameAndThatA's topic in Student Pilot & Further Learning
Responding to several posts... 1 in 60 corrections assume you can hold a heading, so a primary reason is to correct for wind. Wind has more effect on a slower aircraft. A 10 knot crosswind will probably be insignificant for a 150 knot aircraft over 100 miles. It is much more significant for a 50 knot aircraft. How do you figure out how much you need to adjust your heading? That is where the 1 in 60 rule comes in. The idea of the 1 in 60 rule is that if you are flying e.g. 100 miles and are 5 miles off track after 40 miles, you can make a correction that will put you back on track at the 100 mile point so you fly the shortest distance - or at an earlier point if you prefer. When people track visually to something they can see, they often track in a curve if there is a crosswind because they don't apply enough wind correction. It is better to calculate a heading and fly it. Making adjustments to your heading to follow ground features makes it impossible to use the 1 in 60 rule. It relies on accurately flying a constant heading. If you use a wind correction you don't know whether it is too much or too little, so you do not know which side of the planned track you will be. It is possible if you are navigating to a linear feature (river, road etc.) crossing your track to deliberately track slightly left or right so you know which way to turn when you reach the feature. The deliberate left or right angle needs to be larger than other possible errors. When navigating visually the tolerance is 1 mile left or right of track. -
It wasn’t the first option when I looked. It’s an obvious thing to do, I would be very surprised if Survey Monkey didn’t do it. Their marketing angle would be to get the most accurate answers to your survey which would require randomised order. Maybe there would be an option to disable it, I don’t know, but that would require an active choice to bias the survey.

I suspect Survey Monkey randomizes the order for each respondent for that type of question.

So it sounds like a combination of "CASA publish one set of rules but work off a different set" and "the doctor has fudged the certification (with a nudge and a wink from CASA) based on their assessment that you are safe." It seems fairly likely that the DAME has certified that you do meet the unconditional commercial standards. If the doctor certifies it, I'm sure CASA accepts it - it becomes the doctor's problem. I'm not saying you shouldn't be flying. I'm just saying people should not believe that Basic Class 2 is a general - or even a likely - solution for people who can't get a regular class 2. It is certainly not a substitute for the RAA private motor vehicle driver license standard.

That is largely because Australia was a couple of decades ahead of the USA with the AUF Ultralight regulations. The USA didn't take much notice of Australia's ultralight category when they developed their LSA regulations. Australia then decided that LSA should slot in under the AUF/RAA umbrella. As far as I know, LSA in Australia is very similar to the USA, with a few restrictions removed e.g. USA has a maximum speed of 120Kt and controllable pitch propellers are not allowed. Meanwhile, the original Ultralight rules in Australia operate alongside and overlapping LSA.

CASA in their guidance material are quite explicit that if you do not meet the requirements unconditionally, you must apply to a DAME for a Class 2 medical. Here is the CASA Instrument that allows the Basic Class 2 - I don't see any scope for a DAME to assess using different medical standards: https://www.legislation.gov.au/Details/F2018L00980 However, It is possible that there is additional material that I haven't found. It is possible that CASA have an arrangement with DAMEs where they can issue a Basic Class 2 based on different standards - it wouldn't be the first time CASA publish one set of rules but work off a different set. It is possible that the doctor (as I alluded to in point 2) has fudged the certification based on their assessment that you are safe, and under Basic Class 2 they don't have to supply the medical information to CASA. If this is the case they would probably rather you didn't advertise the fact on the internet. I can only work off the information CASA publish, and according to that information you must meet the standards unconditionally or apply for a normal Class 2.

There are many people with a Class 2 medical that will not meet the standard for a Basic Class 2. The Basic Class 2 requires that you unconditionally meet the medical standards for an commercial driver's license. It's a strict enough standard that they had to write in exceptions for glasses and hearing aids. If you don't qualify for a normal Class 2, you almost certainly don't meet the standard for a Basic Class 2. If you can't get as Basic Class 2, you might still be able to get a regular Class 2. The Basic Class 2 has 2 advantages: If you are basically healthy, it is quicker and easier than a Class 2. The Basic Class 2 is certified by the doctor, without referring information to CASA. As I understand it if the doctor says you meet the standard CASA don't second guess them. So it might be easier to find a doctor who will fudge things a bit or not look too deeply at the requirements.

RAAus bid to increase MTOW weight allowance
aro replied to Hunsta's topic in AUS/NZ General Discussion
What does a RA pilot need to do to access CTA? Isn't it as simple as: Fill in a form applying for a RPL Do a RPL flight review, which can incorporate the CTA endorsement and double as a RAA flight review As a bonus you get to fly heavier aircraft. It's not good for RAA as an organization, but for pilots wanting CTA and heavier aircraft I don't understand what more that they want. What are you asking for on top of that?
