  Chapter 5: Aerodynamics of Flight › Load Factors › Load Factors and Stalling Speeds

  Load Factors and Stalling Speeds Any aircraft, within the limits of its structure, may be stalled at any airspeed. When a sufficiently high AOA is imposed, the smooth flow of air over an airfoil breaks up and separates, producing ... abrupt change of flight characteristics and a sudden loss of lift, which results in a stall. A study of this effect has revealed that an aircraft’s stalling speed increases in proportion to the square root of the load factor…

  Chapter 5: Aerodynamics of Flight › Stalls

  critical AOA, but as stated above, it does not completely stop producing lift. In most straight-wing aircraft, the wing is designed to stall the wing root first. The wing root reaches its critical AOA first making the stall progress ... outward toward the wingtip. By having the wing root stall first, aileron effectiveness is maintained at the wingtips, maintaining controllability of the aircraft. Various design methods are used to achieve the stalling of the wing root first. In one design…

  Chapter 7: Aircraft Systems › Turbine Engines › Compressor Stalls

  Compressor Stalls Compressor blades are small airfoils and are subject to the same aerodynamic principles that apply to any airfoil. A compressor blade has an AOA that is a result of inlet air velocity and the compressor’s rotational velocity ... combine to form a vector, which defines the airfoil’s actual AOA to the approaching inlet air. A compressor stall is an imbalance between the two vector quantities, inlet velocity, and compressor rotational speed. Compressor stalls occur when the compressor…

  Chapter 11: Aircraft Performance › Performance Charts › Sample Problem 13

  Stall Speed Performance Charts Stall speed performance charts are designed to give an understanding of the speed at which the aircraft stalls in a given configuration. This type of chart typically takes into account the angle of bank, the position ... throttle position. Use Figure 11-34 and the accompanying conditions to find the speed at which the airplane stalls. Sample Problem 13 First, locate the correct flap and gear configuration. The bottom half of the chart should be used since…

  Chapter 5: Aerodynamics of Flight › Load Factors › Stalls

  Stalls The normal stall entered from straight-and-level flight, or an unaccelerated straight climb, does not produce added load factors beyond the 1 G of straight-and-level flight. As the stall occurs, however, this load factor ... which nothing seems to have weight. The pilot experiences a sensation of “floating free in space.” If recovery is effected by snapping the elevator control forward, negative load factors (or those that impose a down load on the wings…

  Chapter 5: Maintaining Aircraft Control: Upset Prevention and Recovery Training › Stalls › Accelerated Stalls

  Accelerated Stalls While pilots may understand the cause of an accelerated stall, it takes training to experience how these stalls develop and occur. The objectives of demonstrating an accelerated stall are to determine the stall characteristics of the airplane, experience ... stalls at speeds greater than the +1G stall speed, and develop the ability to instinctively recover at the onset of such stalls. This is a maneuver only commercial pilot and flight instructor applicants may be required to perform…
