This paper focuses on the vertical profile of the cruise phase of long-haul commercial
flights covering legislation, operational standards, communications, surveillance, flight
planning and performance aspects. Two case studies are presented: the first one describes and
compares an actual vertical profile of a flight and an optimised one, with detailed calculations
as well as results estimation; the second one compares two vertical profile optimization
procedures strategies. Small modifications in how cruise phase of a flight is operated airlines
can achieve cost reductions, mitigate environmental impacts, and contribute to airspace
efficiency.
