Why This Course
By the end of this course, you’ll be able to:
- Apply the two-part test: does a signal say that you need help, and does it say where you are?
- Pace any signal in threes, and recognize the two-part reply that means help is on the way.
- Identify the internationally recognized distress signals, and know why misusing any of them is a crime.
- Aim a signal mirror, choose the right flare, and build a ground-to-air symbol an aircrew can read.
- Layer electronic, audible, and visual methods into a kit and a plan matched to your activity.
