  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…

  application is completed electronically, the authorized person will submit the application to the FAA’s Airman Certification Branch (AFS-760) in Oklahoma City, OK, via the Integrated Airman Certification and Rating Application (IACRA). If the application is completed on paper ... sent to the local Flight Standards District Office (FSDO), who will forward it to AFS-760. Once the application is processed, the applicant will receive the Student Pilot Certificate by mail at the address provided on the application. The aforementioned…

  Chapter 11: Helicopter Emergencies and Hazards › Retreating Blade Stall

  altitude is increased, higher blade angles are required to maintain lift at a given airspeed. Thus, retreating blade stall is encountered at a lower forward airspeed at altitude. Most manufacturers publish charts and graphs showing a VNE decrease with altitude ... When recovering from a retreating blade stall condition caused by high airspeed, moving the cyclic aft only worsens the stall as aft cyclic produces a flare effect, thus increasing the AOA. Pushing forward on the cyclic also deepens the stall…

  Chapter 5: Aerodynamics of Flight › Stalls

  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 ... 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, the wing is “twisted…

  Chapter 2: Aerodynamics of Flight › Turning Flight › Autorotation (Forward Flight)

  forward speed changes the inflow of air up through the rotor disk, all three regions move outboard along the blade span on the retreating side of the disk where AOA is larger. [Figure 2-49] With lower ... advancing side blade, more of the blade falls in the driven region. On the retreating side, more of the blade is in the stall region. A small section near the root experiences a reversed flow; therefore, the size…

  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…
