  • It’s a bigger deal on bigger aircraft, but on mid-size narrow bodies it’s not as much of a problem. A 737, depending on the model, only has a difference of about 20-30k lbs between MTOW and MLGW and no fuel dump capability. An overweight landing isn’t really a big deal in one, just a quick maintenance inspection. Closing the gap so MTOW and MLGW are equal is doable. It’s hard to overstate how huge of an expense fuel is to an airline, if they have to lose some passengers and cargo they would absolutely do it if it got rid of the fuel expense.

    Of course all that is contingent on having batteries with enough energy density to get somewhere close to current MTOWs while having something of a useful range.



















  • A single pilot would need the ability to control the plane and override automation and that’s a very dangerous thing.

    A single task saturated human in a stressful situation is more of a liability than a benefit. A single pilot can fixate on problems and try to solve them, even if they’ve totally misidentified the situation. Add another set of eyes and you naturally slow things down and handle situations better. The Air France crash in ’09 is a decent example of how one person can totally misinterpret a problem and then the remedy caused a crash, the other crew members were able to figure out what was happening, but it was too late to recover. More crew are an additional chance of success.

    Then there’s the whole one pilot is a single point of failure problem. An incapacitated pilot is a fairly straightforward problem, but what about a '15 Germanwings type of situation where the pilot tries to intentionally crash?
