Re: Electric planes?
Jet fuel can be as low as 20% of the overall weight.
A 787 is 120 tonnes empty, and can carry 180 tonnes of fuel. A 747-800 weighs 220 tonnes empty and can hold 230 tonnes of fuel. It can't land at that weight.
the weight is of most concern at take-of
Landing is also a concern, a 747 can't land with full fuel tanks, it has to dump 100+ tonnes from a full load if it needs to land soon after a maximum-weight takeoff.
