I was looking at the empty weight ratio and I noticed something odd. Both the 787-8 and 787-9 have higher empty weights than their specification read.
The specifications come directly from a Boeing airport planning manual dated Nov 2014.
It concerns me that these are off because if fuel consumption plays a role in global the operating empty weight is critical to calculating how much fuel, passengers, and cargo can be carried. So far the 787-8/9 are the only ones I have tested to be in error.
