Hi Bob and Richard,

I believe references to forecast page numbers in practice might not be correct, perhaps since the addition of page 105? www.bobtait.com.au/media/kunena/attachments/64/METALL105.pdf .

Can you please confirm?

Pages 169 and 170 forecasts are actually similar and got me confused over Test 1 Q10 and 11 for a while. Only after I moved onto Q12 and 13 I realised I was actually looking at the wrong forecast.

Yes, you are correct, it was caused by the addition of page 105.. I have made the changes to the text. Fortunately it only affected the e-text versions and that will be fixed shortly. Thanks for your valuable feedback.

Bob

I found on page 6.29 question
18 Which temp range is most likely to produce rime ice?
a- 0-- -10 c
b -10 - -20c
c -20 - -30c
d -30 - -40c
you have the answer as b, but yet in the book on page 6.13 you have it as -10 - -30c ??
so what answer do we put as u have in the book... b.. but it only seams half right... and why is the difference

Remember that the temperature ranges for icing are at best, a guide and not a scientific fact. Nature isn't that tidy! It's probably best to say that for rime ice it's -10°C or colder. It's hard to put an exact figure on it. However it is true that when the temperature is -10°C or below rime ice is possible. If it's too cold, like below -30°C, most of the water in the atmosphere is already frozen as ice crystals and these do not adhere to the skin of the aircraft so icing is less likely.
