Hi
The issue of the change of battery type for the A350 made me think.
If I read the reports correctly, there was a weight penalty of about 60kg if the 'old' battery type was used. This weight was compared to an adult passenger.
If an A380 is configured for 800+ passengers, what is the likely impact?
Presumably there is a weight penalty of 300 x 60kg = 18000kg (a conservative figure I think). Plus 300 additional sets of baggage.
In addition, extra seats weigh something, and it would be reasonable to expect additional cabin crew and meal facilities.
This must have an impact on take-off and landing weights, as well as fuel use and range.
Perhaps the figures are trivial, but everything about modern aircraft design seems to depend on specific assumptions. If a plane is optimized for a scenario, what are the implications of major changes?
