Email Nathan, he'll provide assistance. After all, if you paid for the notes, then you've also paid for his expertise!
Your EMZW is as has been explained. You take the distance, multiply it by an estimated SGR (10,11,12 or even 13 when it comes to doing DP's), then halve it. That'll be the mid zone fuel. Take that off your Start Zone Weight, and Bob's your uncle, you have your EMZW. Be sure though, to check your MZW to ensure it's the same as the Estimate! Otherwise your figures will be out and there's nothing worse than getting to the end of a 5 stage plan and finding your MZW at Leg 1 was incorrect.
Flight Planning is all about accuracy, combined with speed. So be accurate, but not to the entire detriment of speed.
If all of the above seems too hard and you're turning grey, take my advice; pick up the telephone, call AFT, book yourself onto the next flight planning course. 2 weeks well spent and you'll ace the exam if you pay attention........ And don't spend too much time at Scubar,
Would I sound nuts if I said I actually enjoyed flight planning?
