Section 1: Learning Outcomes
In this exercise, we believe the learning outcomes were the following: Determine the V1, Vr, and Balanced Field Length for the flight profiles. Determining the difference between engine-out performances in regard to the normal performance. Analyze the penalty and see the effect on delayed rejected/ aborted takeoffs; effects of a decision to rotate earlier. See the aircraft’s performance with various headwind and tailwind conditions. Learn to effectively fly the profile in normal conditions and engine out/ emergency situations. Learn to work with different crew members

Section 2: Procedures
For this exercise, the procedures we followed were to initially find out the V1, Vr and the Balanced Field Length for the aircraft. By working as a crew we reviewed the flight profile to see what the flight procedure would be to understand how to determine the speeds for the aircraft. Each crew member had a different role in completing the exercise. One crew member flew the aircraft on the program making airplane inputs; another was reading the directions on the flight profile directing the one flying. We paused the profile any and every time we had a question or found a result; jotting it in our books to gather the results. Section 3: Results
