To maximize efficiency during a flight, what should a transport jet gradually do?

During a flight, to maximize efficiency, a transport jet should gradually climb to higher altitudes. Climbing allows the aircraft to operate in the most fuel-efficient layers of the atmosphere, where the air is less dense. At higher altitudes, there is reduced drag on the aircraft, which enables more efficient engine performance. Additionally, by climbing, the aircraft can take advantage of favorable winds at cruising altitude, such as tailwinds, which contribute to overall fuel efficiency and faster travel times.

Gradual climbing is a critical aspect of achieving optimal flight profiles, as it allows the aircraft to conserve fuel while maintaining performance and safety. This technique helps pilots manage engine thrust and fuel consumption effectively throughout the various phases of the flight.
