We begin with the Super Stall Prevention system, which is the Stick Pusher — Page 145, Lesson 170

This is the start of the Stalling chapter, so let's set the scene. We're moving into the section that deals with the stall itself, and everything that influences it. I want to walk you through the full map of what this chapter covers, because it's a big one, and it's all about one central idea: the stall, what changes its speed, and how you recover from it. We begin with the Super Stall Prevention system, which is the Stick Pusher. That's a device that physically pushes the control column forward to prevent the aircraft from entering a deep stall. Then we get into the heart of the chapter: Factors That Affect Stall Speed. This is a long list, and each one is a separate lesson. We start with the 1g Stall Speed — that's the baseline stall speed in straight and level flight. Then we look at the Effect of Weight Change on Stall Speed — heavier aircraft stall faster. Next, we move into the mathematics of turning flight. We cover the Composition and Resolution of Forces, and then Using Trigonometry to Resolve Forces. That leads directly into the Lift Increase in a Level Turn, because in a turn, lift must increase to maintain altitude. And that brings us to the Effect of Load Factor on Stall Speed — the more G you pull, the faster the stall speed. After that, we look at the configuration changes. The Effect of High Lift Devices on Stall Speed — flaps and slats lower the stall speed. Then the Effect of CG Position on Stall Speed — where the centre of gravity sits changes the stall behaviour. Then the Effect of Landing Gear on the Stall Speed — gear down increases drag and changes the stall. And the Effect of Engine Power on Stall Speed — power changes the airflow over the wing. Then we get into the more exotic effects. The Effect of Mach Number (Compressibility) on Stall Speed — at high speed, compressibility changes the stall. Then Effect of Wing Contamination on Stall Speed — dirt, ice, or frost on the wing. That leads to a Warning to the Pilot of Icing-induced Stalls, and then a specific case: Stabilizer Stall Due to Ice. We also cover the Effect of Heavy Rain on Stall Speed. Then we look at a different configuration entirely: Stall and Recovery Characteristics of Canards — aircraft with the horizontal stabiliser in front. After all the stall speed factors, we move into Spinning. We cover the Primary Causes of a Spin, the Phases of a Spin, the Effect of Mass and Balance on Spins, and finally Spin Recovery — the correct recovery technique. Then we have Special Phenomena of Stall, which includes the High Speed Buffet, also called Shock Stall. And at the end of the chapter, there are the Answers to Questions on Page 173, the Key Facts 2 summary, and a set of Questions for you to test yourself. So that's the full map. We're going to work through it in order, starting with the Stick Pusher and the 1g stall speed. Let's begin.
