When is the low cabin mode utilized?

Using low cabin mode is particularly beneficial during flights that experience frequent altitude changes. This mode is designed to optimize cabin pressurization in scenarios where the aircraft is climbing and descending multiple times, such as in short-haul regional flights or in situations involving irregular flight paths. In these cases, maintaining comfortable cabin pressure efficiently is crucial for passenger comfort and safety.

In contrast, modes like flight at cruising altitudes or operations during takeoff and landing would typically utilize specific pressurization strategies suited for steady altitude. Additionally, utilizing low cabin mode exclusively at sea level or specifically for cruising altitudes does not align with the principle of adapting cabin conditions to frequent altitude variations.
