Collision, Wind Shear & Wake Turbulence Avoidance

Lesson Objective

Regulatory Requirement

• §61.87(i)(6)
• Private Pilot Practical Test Standard IV-G

Content

• 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

• 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.
