You're flying an approach at night or doing preflight in darkness, and juggling a flashlight while holding approach plates is a losing game. This kneeboard gives you both hands back — light mounted right where you need it, plates secured and accessible. You'll actually be able to read your charts instead of playing flashlight tetris.
