  • Chapter 5: Aerodynamics of Flight › Ground Effect

    Ground Effect Ever since the beginning of manned flight, pilots realized that just before touchdown it would suddenly feel like the aircraft did not want to go lower, and it would just want to go on and on. This ... between the wing and the landing surface, as if there were an air cushion. This phenomenon is called ground effect. When an aircraft in flight comes within several feet of the surface, ground or water, a change occurs…

  • Chapter 9: Basic Flight Maneuvers › Go-Around

    Around A go-around is a procedure for remaining airborne after an intended landing is discontinued. A go-around may be necessary when: • Instructed by the control tower. • Traffic conflict occurs. • The helicopter is in a position from which ... time an approach is uncomfortable, incorrect, or potentially dangerous, abandon the approach. The decision to make a go-around should be positive and initiated before a critical situation develops. When the decision is made, carry it out without hesitation…

  • Chapter 4: Effective Communication › Barriers to Effective Communication › Lack of Common Experience

    Lack of common experience between the communicator (instructor) and the receiver (learner) is probably the greatest single barrier to effective communication. Communication can be effective only to the extent that the experiences (physical, mental, and emotional) of the participants ... stimuli used to arouse a response in the learner. Figure 4-3. Misunderstandings stem primarily from four barriers to effective communication. The learner’s past experience with the words and things to which they refer determines how the learner responds…

  • Chapter 4: Principles of Flight › Pressure › Atmospheric Pressure

    Atmospheric Pressure Although there are various kinds of pressure, pilots are mainly concerned with atmospheric pressure. It is one of the basic factors in weather changes, helps to lift an aircraft, and actuates some of the important flight instruments. These ... weight, it has force. Since air is a fluid substance, this force is exerted equally in all directions. Its effect on bodies within the air is called pressure. Under standard conditions at sea level, the average pressure exerted…

  • Chapter 9: Approaches and Landings › Go-Arounds (Rejected Landings)

    Arounds (Rejected Landings) A go-around is a normal maneuver that is used when approach and landing parameters deviate from expectations or when it is hazardous to continue. Situations such as air traffic control (ATC) requirements, unexpected appearance of hazards ... unstable approach are all reasons to discontinue a landing approach. Like any other normal maneuver, the go-around should be practiced and perfected. The flight instructor should emphasize early on, and the pilot should understand, that any approach or landing…

  • Chapter 9: Approaches and Landings › Go-Arounds (Rejected Landings) › Ground Effect

    Ground Effect Ground effect is a factor in every landing and every takeoff in fixed-wing airplanes. Ground effect can also be an important factor in go arounds. If the go-around is made close to the ground, the airplane ... ground effect area. Pilots are often lulled into a sense of false security by the apparent “cushion of air” under the wings that initially assists in the transition from an approach descent to a climb. This “cushion of air,” however…
