This is the Preflight checkist There are two kinds of line items, which we call open-loop and closed-loop items. The open-loop items have a gray check-box in front of them. These are items that the airplane systems cannot sense. The pilot determines whether the items have been completed and clicks the CCD thumbswitch when each item is complete Closed-loop items are for switches and selectors that are sensed by the airplane systems. they automatically turn green when the switch has been positioned correctly. If the crew actuates the wrong switch, the closed-loop item will not turn green and the crew will catch their error. In this example, the procedure was already complete, so the last two items are shown in green as soon as the checklist is displayed The white current line item box leads the pilot through the checklist and prevents accidentally skipping a line item Color is used to indicate line item status. Incomplete items are displayed white and complete items are displayed green. Cyan(or blue)indicates an inapplicable item, or an item that has been intentionally overridden by the crew using the ITEM OVRD button. In this example, the fight is dispatching with autobrakes inoperative, so the crew has overridden the AUTOBRAKE item. Overriding the item allows the checklist to be completed
