Hi Bob,

It appears that the answers have the GS out and GS home figures back to front.

Q7. States tail wind of 15 kts. When wind is from 220M and FPT is 220M??

Q8 Sates the wind as an exact Headwind of 10 kts. Wind at 250T / 240M and FPT is 060M??

Unless I am missing something.

These questions were changed some time ago in the book and I forgot to change the download. Here is the new version. Hope it hasn't caused you too much anguish. Sorry about that.

I am using the ebook version. As per above, I see that these issues have been updated. But looking at Q7 in the current ebook version, the answer is (a), 78nm, 49mins. I calculated 102.2nm, 49mins.

That's a typo in the answer it should be (d) I'll amend that answer

Hi Bob, Stuart,

Question 8.
Any particular reason for not subtracting Taxi fuel 3gal from [172-17.25-17] ?
The difference in results is not big but I am interested in principles, i.e. when should I ignore taxi and when not.

For example I understand the wording when the question says "fuel at takeoff" means no taxi, but in this case fuel is observed 103nm from departure.

Thanks
