It is my impression that an increasing number of airline passengers place cabin-sized suitcases in the overhead lockers.
1. Does anyone know whether there is an increased number of accidents from suitcases falling down when opening the overhead lockers?
2. Does it make a big difference for the pilots to fly the planes if most luggage is stored in the overhead lockers instead of the storage room? There are usually regulations in terms of number of items, size and weight of luggage declared as hand luggage, but what if these are not always adhered to?
As it seems, there is probably not enough publicly available information to answer this question.
In case you nevertheless have an answer or a guess based on your expertise, please feel free to contribute anytime.
Yours sincerely,

Typically the fuselage is centred around the Centre of gravity of the aircraft. Baggage can be underneath the floor, or in others (smaller) at the tail- or in the case of ATRs at the front. Airlines do check size and weigh of carry ons. and its obvious when bags are being lifted into the OH bins if they are heavy.. And the flight attendants do intervene. Once upon a time, we were testing a smallish airliner and two of us ran with a loaded in flight catering cart up and down the aisle to see how we could disturb the AC... This was say 500 pounds moving from one extreme to the other.. and the AC just sat there.. If every carry on bag was from a coin collector and they all sat at the front, (or rear) then there might be a Centre of gravity problem, but generally the distribution is symmetrical around CG and most airliners have a pretty wide CG range anyway- say 5% to 35% of MAC. The limits being stability at aft CG,, and ability to rotate at fwd CG... Could go on for hours on this if you wish
Dear Dr. Innes,
thank you so much for your detailed answer. I appreciate this a lot. The information you provide makes a lot of things clearer.
Yours sincerely,

email me on [email protected] if you wish to pursue futher.. I was once moving "house" back to UK and at the time yu could.swap carry on for checked, so I checked several bags, but had a buddy holding my carry on.... well lets just say it was barely portable- lots of high density, high value items... I reckoned about 100 pounds, but having wheels no one bothered... Saved me $100,,, and if the AC had been full of people like me, it would have cost me my life
