Fly Antonov,
I have no wish to defend the JAR/EASA pilot training system, but I think that you will add more to the level of knowledge of student pilots by answering some of their questions, instead of simply pouring ridicule on anyone who asks a question.
Most of the people who ask questions in this forum do so in an attempt to increase their knowledge and understanding.
The people who intend to simpy memorise answers are too busy banging away at their on-line databases.
Your habit of attacking everyone who asks what you consider to be a simple question, will simply discourage them from asking any questions at all. Is this really what you want to achieve?

Your difficulty in recognising the square law relationship between speed and dynamic pressure is not at all uncommon. I would estimate that at least 80% of JAR ATPL students have problems with it initially, and something like 40% never quite overcome these problems.
