Lesson 4a - Collision, Wind Shear & Wake Turbulence Avoidance

Lesson Objective

The student will review scanning techniques. The student will learn of the hazards of wind shear; the student will learn the hazards of wake turbulence.

Regulatory Requirement


  • Wake Turbulence Generation, Strength, Behavior, Problem Areas and Avoidance
  • Wind Shear, definition and impact on aircraft performance (especially on final!)
  • Collision avoidance, see and be seen.
  • Review scanning techniques lesson 2b

Completion Standards

The student must be able to perform:

  • Appropriate scanning techniques throughout every flight
  • Appropriate situational awareness of windshear and wake turbulence

The student must be able to explain:

  • Risk factors in midair collisions (especially as related to gliders)
  • Collision avoidance technology
  • the factors that create wake turbulence
  • the factors that create the strongest wake turbulence
  • how to avoid wake turbulence
  • what wind shear is, and how it relates to aircraft performance.
