The rest of this page is just the answer key for questions 1 through 43 — Page 214, Lesson 253

This is the tail end of the question bank for the climb-performance chapter — the last few answer options and then the answer key. Since these are the book's practice questions, I won't read the stems or give away the correct letters. Just know that the options you're looking at here are the classic climb-performance comparisons: best rate of climb versus best angle of climb, and what happens when you fly slightly faster or slightly slower than those optimum speeds. The key distinction to hold onto: best rate of climb gives you the greatest height gain per unit of time, while best angle of climb gives you the greatest height gain per unit of horizontal distance. If you fly slightly slower than the best-rate speed, you get a slightly reduced rate of climb. If you fly slightly slower than the best-angle speed, you get a slightly reduced angle of climb. That's exactly what these options are testing. The rest of this page is just the answer key for questions 1 through 43. I won't read those out — the app will present the questions to you one at a time, and you can work through them interactively. Let's try them one at a time.
