an emergency stop on the runway
While it may not be something you see on a "required skills" schedule the checker may have just been seeing how the person would react to some thing out of left field. There are occasions where an emergency stop may be required. Some one taxi onto the runway in front of you (does happen) or in some parts of the world you have to contend with the wild life (cattle, sheep, deer, kangaroos). Some very, very expensive aircraft have been written off after encountering same. Good luck with the test, as others have said, your instructor would not put you up for it if he thought you not ready. Remember, often the most senior of aviators can get anxious and suffer sweaty palms when it comes to check time (I certainly did), and checkers realise this and make due allowances (if they are any good themselves). A good checker does not go looking for a reason to fail, he too wants you to join this magical world. Enjoy
