Sorry to be a nuisance but I have a query or two on the Operational Meteorology answers I fumbled through this afternoon.
Q19. Difference b/w an Airmet and a Sigmet? The answer in the notes is B. Relates to aircraft operating at or below FL200. The AIP 3.5 para 5.3.2 mentions aircraft operating at or below 10,000 ft.
Q23. The answer in the notes is A. I am unable to find an explanation in the AIP with the references given. AIP para 12.1 (c) Is this a typo? Similar to the ENR reference ENR 1.1 para 58.1.3? I found that explanation in ENR 1.1 para 18.104.22.168
You're never going to be a nuisance mate.
Question 19. This has been changed since March. It used to be 20,000 feet but it is now at or below 10,000 feet. It has been changed in the latest print of the book.
Question 23. Once again the latest version of the AIP gives completely different references for many topics. We got no warning from Airservices about that. The reference is now indeed 22.214.171.124. You will find a download under 'Met Errata' on our web page the summarizes all of the changes to AIP references. They have all been changed in the latest print of the book.
