Which seat belts must be buckled during operation of MAGGIE14LR?

In a helicopter like the MAGGIE14LR, it is crucial for safety that seatbelts are used correctly. The correct answer specifies that only the left seatbelt must be buckled during operation, which is consistent with the specific operating procedures and safety requirements established for this model.

Typically, this could be due to the pilot's seat being designated as the primary seat for operations, particularly during takeoff and landing, where additional safety measures are emphasized. Regulations and manufacturer instructions often focus on the left seatbelt in single-pilot operations, as it is the seat primarily used by the pilot.

It's important to note that other seating positions may have varying requirements based on helicopter configurations and the number of occupants. In this instance, both seatbelts may not be mandatory for operation if there is no passenger in the right seat or if its use is not explicitly required for safety under normal operating procedures.
