Many thanks everyone..... Also, I am due to sit FAA aptitudes, which I know are similar to the RAF aptitudes, but was wondering, what sort of mathematical questions are given to you to resolve? And also to what extent- e.g. I know there are speed=distance/time, but are these simple, or do they require long division etc? Also, am I right in saying there are questions along the lines of "If Aircraft A is moving at 220 knots and Ba t 115 knots, what point will they intercept?".....
Your help is much appreciated....
