- 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 1. GROUND TRAINING: STALL AND SPIN AWARENESS › 104. TYPES OF STALLS
TYPES OF STALLS. Stalls can be practiced both with and without power. Stalls should be practiced to familiarize the student with the aircraft’s particular stall characteristics without putting the aircraft into a potentially dangerous condition. In multiengine airplanes, single ... engine stalls must be avoided. Descriptions of some different types of stalls follows: a. Power-off stalls (also known as approach-to-landing stalls) are practiced to simulate normal approach-to-landing conditions and configuration. Many stall/spin accidents have occurred…

Cross Controlled Stalls in Gliding Turns. Perform stalls in gliding turns to simulate turns from base to final. Perform the stalls from a properly coordinated turn, a slipping turn, and a skidding turn. Explain the difference between slipping and skidding ... turns. Explain the ball indicator position in each turn and the aircraft behavior in each of the stalls. e. Power-Off (Approach-To-Landing) Stalls (1) Have the student perform a full-flap, gear-extended, power-off stall with…
- CHAPTER 1. GROUND TRAINING: STALL AND SPIN AWARENESS › 100. STALL/SPIN EFFECTS AND DEFINITIONS › g. Load Factor
Load Factor. Load factor is the ratio of the lifting force produced by the wings to the actual weight of the airplane and its contents. Load factors are usually expressed in terms of “G.” The aircraft’s stall speed increases ... proportion to the square root of the load factor. For example, an airplane that has a normal unaccelerated stall speed of 45 knots can be stalled at 90 knots when subjected to a load factor…
- 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 ... reduced toward zero, the factor at 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…

CHAPTER 2. FLIGHT TRAINING: STALLS 200. STALL TRAINING. Flight instructor-airplane and flight instructor-glider applicants must be able to give stall training. The flight instructor should emphasize that techniques and procedures for each aircraft may differ and that pilots ... each aircraft flown. The most effective training method contained in Report No. FAA-RD-77-26, General Aviation Pilot Stall Awareness Study, is the simulation of scenarios that can lead to inadvertent stalls by creating distractions while the student…
