Reading the EASA A320neo certification document, we came across this item.
This suggests the LEAP-powered A320neo weighs 300Kg or ~660 pounds more. Which is especially interesting given the GTF is the larger of the two. Also, a heavier engine likely requires a more robust pylon.
Co-Founder AirInsight. My previous life includes stints at Shell South Africa, CIC Research, and PA Consulting. Got bitten by the aviation bug and ended up an Avgeek. Then the data bug got me, making me a curious Avgeek seeking data-driven logic. Also, I appreciate conversations with smart people from whom I learn so much. Summary: I am very fortunate to work with and converse with great people.
