I hope they have a rethink on the current nav paper as some of the questions are so far removed from PPL knowledge they are just ridiculous and I cant even find ATPL holders who can answer some of them.
One of the answers could only be referenced in the Pooleys APM PPL textbook, not much help to someone who just purchased a set of AFE books!
What is needed are some questions that will encourage pilots to stop penetrating controlled airspace not understand the mechanics of the tilt axis of the earth and the upper limb of the sun. I think we can safely assume that most PPLs know when its getting dark and light!
