Collision, Windshear & Wake Turbulence Avoidance

Lesson Objective

Regulatory Requirement

• §61.87(6)(2)
• 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

The student must be able to explain

• Risk factors in midair collisions (especially as related to gliders)
• 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.
