Thanks for the replies.
I've actually been using flight sim for many years. I started way back with Flight unlimited 2.
I normally try to fly "to the book" with the complex add ons such as the PMDG 737NG, DF737, PIC767 etc. Flight sim has taught me quite a lot, VOR nav, Airways etc so I've sort of had a head start and starting the PPL has helped too.
I do practice decent rates quite a lot when im flying aircraft without FMCs etc. I can do it all right but that is all i know really. That and the opposite headings of a compass.
I need to find out what sort of math needs to be done on a day to day basis for the average airline pilot so i can practice at it.
I'm thinking about buying one of those mental maths for pilots books. I bought one a while ago but I didn't think it was very good. Do you have any recommendations? There are a few available.
The standard GCSE math revision books help a bit too.
Thanks again
I really appreciate it.
