What must No2 ensure is on during the short notice time available on land drill?

During a land drill, it is crucial for No2 to ensure that the emergency lights are operational. The primary focus of a land drill is to prepare crew members for situations where they might need to evacuate the aircraft due to an emergency on the ground.

Having emergency lights activated plays a vital role in helping crew members and passengers see clearly and navigate safely, especially in low-light conditions or if the main cabin lights go out due to an emergency. This visibility is essential to ensure an orderly evacuation and to guide passengers towards the exits effectively, minimizing confusion and potential injuries during an evacuation scenario.

Other equipment mentioned, such as oxygen masks, emergency locator signals, and evacuation slides, serve different primary functions. Oxygen masks are used in scenarios involving an in-flight cabin depressurization, locator signals are crucial for search and rescue in emergencies at sea or remote areas, and evacuation slides are deployed during an actual evacuation to facilitate quick exit from the aircraft. However, in the context of a short notice land drill, emergency lights are the immediate function that directly enhances safety and preparedness.
