Preflight Kit showing a Piper PA-28-161 Warrior II: its tools, and the aeroplane drawn to its own span and length.

Why we built it

Most of learning to fly happens on the ground.

Preflight Kit is for the kitchen table the night before the lesson. Change one number and the drawing changes with it. That is the part a whizz-wheel cannot do: show you what a number means while you are still learning what it is.
