Stall Switch
Another detail that has to be completed before the skins go onto the wings is the installation of the stall warning switch (only on the left wing). It is a simple micro-switch with a tongue on it that protrude through the wing skin at the leading edge of the wing. During a “stall” (when the wing stop flying), the pressure changes at this point in the airfoil enough to activate the tongue/switch combination. The switch will warn the pilot of the condition, by activating a horn or alarm in the cockpit. A very simple, yet important device.
