Duncs,
AEOs don't concur!
They disagree by 5-10 degrees and 1 knot, to try and show that they actually have an opinion of their own!!
Not quite. They work out the correct course and speed. Extrapolate the mean from the Lead Weight, and two directional consultants, apply a correction factor and give the "tactical" directional consultant a slightly spurious figure so that once he has mixed it all up the answer comes back what the AEO wanted in the first place. Then he allows the tactical directional consultant to take the credit, get his B Cat, get promoted, and become a Sqn Cdr.
None of this matters to the AEO because he has the fastest car, the biggest house and the prettiest wife.
Happy Days
