When can a passenger use a standard size laptop computer on an aircraft?

A passenger can use a standard size laptop computer on an aircraft when the aircraft is above 10,000 feet. This policy typically aligns with aviation regulations, which are designed to ensure safety during critical phases of flight, such as takeoff and landing.

During these phases, passengers are often required to have their electronic devices stowed to minimize potential hazards. Once the aircraft reaches a cruising altitude, usually above 10,000 feet, passengers are generally allowed to use larger devices, such as laptops, as the risk of turbulence and the need for immediate safety measures decreases.

Additionally, the airline's specific rules may vary, but the common practice is rooted in the need for heightened safety protocols when the aircraft is operating at lower altitudes and is more susceptible to changes in speed and maneuverability.
