| References | FAA-H-8083-2,FAA-H-8083-3; AC 61-67; POH/AFM | |
| Objective | To determine that the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls | |
| The applicant demonstrates understanding of | ||
| K1 | Aerodynamics associated with stalls in various airplane configurations, to include the relationship betwen angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects. | |
| K2 | Stall Characteristics (ie., airplane design) and impending stall and full stall indications (ie., how to recognize by sight, sound or feel) | |
| K3 | Factors and situations that can lead to a power-off stall and actions that can be taken to prevent it | |
| K4 | Fundamentals of stall recovery | |
| The Applicant demonstrates the ability to identify, assess and mitigate risks encompassing: | ||
| R1 | Factors and situations that could lead to an inadvertent power-on stall, spin and loss of control | |
| R2 | Range and limitations of stall warning indicators (e.g., airplane buffet, stall horn, etc.) | |
| R3 | Failure to recognize and recover at the stall warning during normal operations. | |
| R4 | Improper stall recovery procedure | |
| R5 | Secondary stalls, accelerated stalls elevator trim stalls, and cross-control stalls | |
| R6 | Effect of environmental elements on airplane performance related to power-on stalls (eg., turbulence, microbursts, and high density altitude) | |
| R7 | Collision hazards to includ aircraft, terrain, obstacles and wires. | |
| R8 | Distractions, or improper task management loss of situational awareness, or disorientation | |
| The applicant demonstrates the ability to: | ||
| S1 | Clear the area | |
| S2 | Select an entry altitude that will allow the Task to be completed no lower than 1,500 feet AGL | |
| S3 | Establish the takeoff, departure or cruise configuration as specified by the evaluator, and maintain coordinate flight throughout the maneuver. | |
| S4 | Set power (as assigned by the evaluator) to no less than 65 percent power | |
| S5 | Transition smoothly from the takeoff or departure altitue to the pitch attitude that will induce a stall | |
| S6 | Maintain a specified heading +/-10° if in straight flight; maintain a specified angle of bank not to exceed 20° +/-10° if in turning flight, while inducing the stall. | |
| S7 | Acknowledge cues of the impending stall and then recover promptly after a full stall occurs | |
| S8 | Execute a stall recovery in accordance with the procedures set forth in the POH/AFM | |
| S9 | Configure the airplane as recommended by the manufacturer, and accelerate to Vx or Vy | |
| S10 | Return to the altitude, heading and airspeed specified by the evaluator | |
