What is required to facilitate passenger evacuation through the entry door during a fire?

Facilitating passenger evacuation during a fire emergency requires the jet bridge and stairs to be in place as a means of ensuring a safe and quick exit from the aircraft. The jet bridge provides direct access from the airplane to the terminal, allowing passengers to evacuate without having to navigate external hazards. When stairs are available, they extend the evacuation route, allowing passengers to disembark safely to the ground.

In situations involving fire, the quick and efficient evacuation of passengers is paramount. A jet bridge helps to minimize exposure to smoke or flames, while stairs provide an alternative exit point if the jet bridge is not accessible. Having both options available enhances safety and increases the efficiency of the evacuation process.

While emergency lighting is important in guiding passengers towards exits, and a manual slide could potentially assist in evacuation, these alone do not ensure a reliable and effective exit route equivalent to having both a jet bridge and stairs ready for use.
