The purpose is to determine that students possess the skills to cope with distractions while maintaining the degree of aircraft control required for safe flight.

This technique is best done while using a simulator.

Example: 

Take the brake toggle (throttle hand) and wrap it through the riser or the other lines. Have the student simulate the untangling process while maintaining smooth and consistent throttle control. The goal is to practice “flying the aircraft” while dealing with the distraction of untangling the brake toggle.
