                        <content:encoded><![CDATA[Respected all, there was one Question in the GK exam that I simply did not understand ( although I passed )

I cant recall exact but there was a question to check on the Magneto ground wire
it asked various options to either turn off the ignition, then testing the magnetos, or putting the engine on full RPM, or idle tne turning off the masters or the battery switch. There were various combinations of these. I couldnt really make sense of the wording and there were 5 options in contrast to the usual 4. 
I know the mag check at 1700 and turning the mags left and right but I couldnt find anything in the books. Maybe Im not reading this carefully enough however, if anyone has thoughts I would be grateful

Kind regards

                        <content:encoded><![CDATA[Hi All, just did the general knowlege today and passed 80%

The exam had  many questions very similar or identical in stem to the questions in the Tait books and practice exam. 
The questions that I had got wrong, I simply did NOT even have an idea of the answer and there were questions that were so poorly worded it was more akin to an exam on comprehension rather than a knowledge based thing I feel . 

My suggestion is that 
1. Read the book very carefully. I would summarise the whole book and every sentence. 
2. Draw the diagrams of the systems and with each system, know the parts and write down what that part does... Then
3. When you know the parts, write down what would happen if there was a problem with that part. 
4. Eg, when the accumulator fails- what will happen to the system.
5. There were many questions on the electrical system, turbines, mixture control, manifold pressures 
6. There were questions on ice and its effect on the RPM, MAP, carburettor
7. Many question on oil T and P , these are v similar to the tait questions
8. Question on directional gyro errors. Now I on the forums I have seen in the past, the question was along the lines of the DG moves with the rotation of the earth. I put Apparent drift but then directional gyro came up on my KDR. So now I don't know. 
9. Now there are many questions in the mixture control, or electrical systems so Im unsure which q. I got wrong because the KDR are a broad brush strokes. I may as well say that the whole book is my KDR! but obviously passed.
10. The invigilator gives you a pad. Write down all the questions and do the ones you know immediately and come back to the ones you have queries. 
11. I did the exam in 1 hour and 15 minutes having 25 to spare. This included the time to review the questions I had issues with. Frankly, these were so confusing that returning to them, still did not solve my dilemma! 
12. I was getting higher on the Bob Tait exams over 90 %. My suggestion is aim for this and accept a 10% drop in the exam. Im not saying this universal for everyone but each and every CASA exam has had this trend..

Good luck everyone it is passable. 
Thanks again Bob

                        <content:encoded><![CDATA[Hi all, 

I'm two weeks out from my first CASA exam, self-studying, and chose to do CSYA first. Started off reading through the text in full, completing each exercise after each chapter, and now doing practice exam after practice exam. I've completed all practice tests in the textbook and seem to be consistently achieving only 70-80% each time - it's almost as if I've plateaued. After marking each exam I go back into the textbook and study the content relating to the questions I got incorrect and take physical notes, but it seems that I can't scores any higher than 80% at most. 

I'd love to know any tips/tricks, or maybe even a different way to study so that I can start achieving higher in the practice exams and be better prepared - or should I look at pushing back the real exam? 

Thanks in advance :)]]></content:encoded>

                        <content:encoded><![CDATA[Exercise GK 2 Question 1:
The manifold pressure gauge on an inoperative engine would be expected to read:
A) 1013.2hPa
B) Zero
C) the ambient atmospheric pressure
D) 30Hg"

based on the information given on page 2.7 of CPL General Knowledge which states the "When the aircraft is parked with engine inoperative, the normal outside pressure floods through the inlet manifold, so that at sea-level the manifold pressure gauge would read about 30HG"

Based on this information i selected 'D) 30Hg"' however i got it wrong because the correct answer is 'C) the ambient atmospheric pressure'. Can some please explain me why is the correct answer? I have gone through the explanation which is present next to the answer but got confused. Any form of explanation will be much appreciated.]]></content:encoded>

                        <content:encoded><![CDATA[Hi Bob and Co,

Q) If a heat soaked engine will not start due to fuel vaporization an appropriate action will be...

A) Operate the prime pump with the mixture in idle cut off to purge the vapor

The explanation in the answers section states that this will circulate cool fuel through the system and cool down the fuel lines. I understand that heat and low ambient pressure cause fuel vaporization but why would you put the mixture to completely lean? Wouldn't fully rich make cool the lines more?

Thanks]]></content:encoded>

                        <content:encoded><![CDATA[I passed the CPL GK exam today. 

I was averaging 93% for Bob's practice exams, but only got 83% for the CASA exam. As Bob says in the book, don't just rely on knowing the answers. A full understanding of what is happening in each topic is required. Even more so, when CASA throw in curly questions and add useless, misleading, or redundant words in the question.

I was asked a questions about what causes gyroscopic errors. CASA's choices, used words that I think were meant to confuse. Eg Real precession, Apparent precession, Earth travel precession etc. The 4th choice was something about mechanical stuff, which sounded totally stupid. But in the heat of an exam, all I could remember, were the choices given in practice exams, which usually had one correct answer of drift and precession, so I'm thinking, which precession answer do I choose? Then I remembered the book having a graphic showing the earth and precession, but I couldn't remember the book saying it was Apparent Precession, so, being a visual learner, I just went with the earth travel precession. Meaning CASA got me and I missed the real answer.

Another question was about being given green fuel instead of the 100LL you wanted and what would be the consequence of using it. I got this wrong, just because I hadn't studied that enough, or done enough questions on that topic. I think the answer is to do with lead fouling, but I put detonation, which in review is wrong, because the fuel is too good compared to the 100LL and wouldn't detonate.

I got a left zero ammeter question wrong. They asked how to test if the alternator has failed. I think I selected zero means it has failed.

Other questions I got wrong were 
- a static vent blockage on descent and its impact on the altimeter. No idea how I got that a wrong, I thought I had those understood pretty well.
- a boost pump operation question, why is it used? I think I selected that it assists the engine driven pump, to keep pressure.
- abnormal engine instrument indications. I can't even remember the question for that one.
- a question about turbo systems, of which there were a few.

In the end, everything is in Bobs book and while there were quite a few questions that were identical to the practice exams. Don't rely just on that, or you'll be disappointed.

Hope this helps anyone.

Cheers]]></content:encoded>
