Weight distribution in a Boeing 737

264 viewsEngineeringOther

Currently on the tarmac waiting for my flights to tax out from the gate. The stewards have called out three times “while this flight is not full, please stay in the seat allocated on your boarding card to make sure we have the right weight distribution during takeoff”. Can really one or two passengers moving change the weight distribution on a 50 000 kg airplane (250M 🦅-units) enough to have an impact?
Or is this just BS? As a frequent traveler I hear this argument a lot..

I mean, 10 people could easily be 1,000kg. Add the lever effect and 10 people moving from say the back to the front could have a reasonable effect on the handling. Maybe it would still be safe, but you don’t want to take any risks.
