   To periodically climb to higher and higher altitudes during cruise flight, as the aircraft becomes lighter from fuel burnoff, to take advantage of the reduced drag at higher altitudes; like cruise-climbing, but with the aircraft climbing in discrete steps instead of continuously.

   • The flight plan called for step climbing from an initial cruising altitude of FL330 to the final altitude of FL350 halfway through the flight.
2. 2

   An instance of step climbing.

   • The step climb from FL340 through FL360 and FL380 to FL400 will reduce our fuel burn compared to if we cruised at FL340 for the whole flight.
