# What is fuel consumption of an A330 during climb and descent?

I want to know how to calculate or estimate an aircraft's fuel consumption when climbing from sea level to 15,000 ft, followed by a descent to 10,000 ft.

I would like to see an example for an Airbus A330-300 with CF6-80E1A4 engines.

• This depends on the aircraft in question. Your specific aircraft should have performance tables that give fuel consumption figures, but without that, it would be a pretty wide estimate. – Zach Lipton Nov 1 '18 at 6:09
• Hello and welcome to Aviation.SE. Unfortunately we cannot answer your question here because calculating fuel consumption is covered by an entire chapter in a ground school book. It is too much for us to cover. – kevin Nov 2 '18 at 2:28
• One approximation could be done with the total energy, the specific energy density of the fuel and the engine efficiency. (sum of kinetic and potential energy in J ) / ( J per kg fuel ) / ( efficiency ) = kg of fuel – Jan Nov 2 '18 at 7:37
• Thank you for answer, do you mean kinetic energy 0.5*mv2, and potential energy mg*h? – Freddy David Nov 9 '18 at 7:00
