INTRODUCTION
The subject of aerodynamics could well occupy years of study at the tertiary level. Obviously the CASA does
not require such depth of knowledge. The questions which accompany this text give an indication of the level of
knowledge required in the examination. It is impossible to go far with a study of aerodynamics without resorting
to some mathematical presentation.
In my years as a teacher of aviation subjects I have become very conscious of the fact that the moment any math-
ematical argument is introduced, many students react like a cash register with the 'NO SALE' flags in the window.
Before we begin let me make this promise to you.
PROMISE
There is absolutely no reason why you cannot get 100% in the CASA Aerodynamics PEXO (Pilot Examination
Office) examination without calling on any mathematical ability at all.
However throughout this text you will find some concepts presented as a mathematical argument. If this leaves you
cold, you can ignore it completely as long as you accept the 'punch line' at the end. I have made every endeavour
to follow any mathematical presentation with a plain English statement of the fact.
What finally matters is the way you go about your study. Please don't fall for the trap of attempting to 'learn' the
questions. The questions are useful as a means of testing your grasp of the subject matter, but you must be sure
to read the text carefully and make your own notes as you go. It is also sometimes useful to cover up the answers
to the question and try supplying your own answer in your own words before reading on. All questions are ac-
companied by fully explained answers.
