Q
  1. A strong steady wind exists out of the north. You need to photograph an area to the south of your location. You are located in an open field with no obstructions. Which of the following is not a concern during this operation?
  • Strong wind may exceed the performance of the sUAS making it impossible to
  • Turbulent conditions will likely be a significant factor during the operation
  • Strong wind conditions may consume more battery power at a faster rate than in calm conditions
A

Turbulent conditions will likely be a significant factor during the operation
