  18.  @B_Estes_Undegöetz  I am a CFI-I in both Airplanes and Helicopters, and a Mechanical and Aerospace Engineer. Wing Loading is very relevant. When pulling Gs, your wing loading is increasing. The aircraft is effectively getting heavier. The wings can only supply so much lift at a given airspeed, and so to maintain flight at a given altitude must increase AOA to compensate as the G-load increases. This puts your AOA closer to its max angle at a higher airspeed. Now, a 60deg banked turn, while descending and not trying to hold altitude, induces how much G-load on your aircraft? 2G? No, only 1G is on your aircraft. The 2Gs in a 60deg banked turn only applies when maintaining altitude in the turn. This is something many pilots and CFIs struggle with. Another concept many pilots and CFIs alike struggle with, is the concept of maneuvering speed, and why maneuvering speed increases with weight. Do you understand what an Accelerated Stall is, and what causes it? Also, an airplanes minimum published flying speed (stall speed, Vs and Vso), is calculated for Max Gros Weight. But if you lighten the plane up, you can stall the aircraft well below stalling speed, depending upon how much payload capacity your aircraft has relative to the weight of the airplane. I would demonstrate this with student pilots even in a lightly loaded C172 by flying slow flight with the airspeed dropping to zero (position error combined with standard instruments not working well below ~40kts). But we were still flying and maintaining altitude, and the airspeed needle visibly went lower than published stall speed before dropping away to zero. Can you cite a single place in any of the FAA publications where it says, “disturbed airflow over the wings”? I'd like to see what they have to say on teh issue. What causes disturbed airflow over the wings? Did you know turbulent flow, and flow separation over the wings is occurring Well above stalling speed? What makes a "laminar flow airfoil" different from other airfoil shapes? How does curvature of a wing produce lift? I bet you don't actually know. It's not Bernoulli's principle, as to use Bernoulli you have to have 3 conditions (one of which doesn't exist in real world, as well as constriction of airflow (venturi effect), which has been shown not to be a factor. There is a far better explanation out there, a new principle, by a much younger Aerospace engineer who is alive today. Can you explain the role and purpose of flaps, and what effect they have on stall speed? Most pilots and CFIs cannot. They only know the book answer and only know how and when to use them when their checklist and/or procedures tell them to.
