Final answer:
The exits on larger commercial aircraft are typically equipped with dual lane slides to ensure a more efficient evacuation during an emergency. These are found at main doors and are designed to support the rapid disembarkation of a large number of passengers.
Step-by-step explanation:
The question "Which exits are equipped with dual lane slides?" likely pertains to the exits on aircraft equipped with emergency evacuation slides designed for rapid disembarkation.
Aircraft evacuation slides are safety devices that allow passengers to quickly leave an airplane in case of an emergency on the ground, such as a fire or a water landing. Airplanes, especially larger, commercial airliners, may have dual lane slides at main exits which allow for a larger number of passengers to evacuate simultaneously. These slides are broader than the single lane slides and unfold into two lanes after deployment, enabling a more efficient evacuation.
Depending on the aircraft model, typically, over-wing exits do not have slides, as they are intended for use when the aircraft is capable of a relatively safe landing where main exits are unusable. However, main doors, especially in larger aircraft like the Boeing 777 or Airbus A380, will have these dual lane slides due to the number of passengers and the height from which they would need to evacuate.
