I know that in the airline industry, weight is money; but can this be worth the trouble ? It allows another 10 or so pax, or another ton of fuel. I assume (maybe incorrectly) that number of passengers is limited more by seating space than MTOW, so we're talking another ton of fuel. I believe these babies consume about 10 tons of fuel an hour at cruise, so we're talking 6 more minutes of flight or about 50 nm. How much can this retrofit cost and be worth it ?
