What controls emergency landing gear extension?

Explanation:
The ability to extend the landing gear in an emergency is commanded by the landing gear control in the cockpit. The LDG gear control is responsible for routing hydraulic pressure to the gear actuators and initiating the extension sequence, including using the alternate/extending path if the primary system isn’t available. In other words, this control directly manages the gear down action, even under abnormal conditions. The APU switch and engine start switch don’t provide a direct gear-down command, and a manual override isn’t the standard driver for emergency extension, so the LDG gear control is the correct choice.
