Center Of Gravity Concerns Lead To Lufthansa Pulling Last Economy Row On A320neo
German national flag carrier Lufthansa has stopped selling the last row of seats in its Airbus A320neos due to concerns over the aircraft’s center-of-gravity limitations. (simpleflying.com) Más...I always find these threads interesting and funny to read, as the general public, and even aviation enthusiasts, often show their technical ignorance in their comments.
Engineering a complex system of systems such as a modern airliner or a nuclear power plant is a constant learning process. Anyone that thinks some third party certificate, FAA in this instance, means fool proof airworthiness, should really pull their head out. At best it is Probabilistic estimate that in most cases, with decently trained crew, things will be ok...but human error in design, manufacturing, testing, certification, maintenance, and finally operations continue to show the world that nothing is fool proof or 100% safe under all conditions.
The general tennis match of blame is a bit childish, folks will always debate B v. A, just as they do Chevy v. Ford.
In my opinion, Effort should be focused on learning from mishaps and making constant process improvements in engineering and operations

OMG you mean you cant cram an extra 20 seats on an plane and make all that money! Maybe the manufacturer already did the numbers or it would have come that way.
the first A320 to fly passengers flew right into a Forrest after not being able to maintain altitude for those of you who think there's any difference between A and B - take a look at how many 47's have crashed or triple 7's - both companies have cultural issues, For crying out loud Airbus built the A380 after Boeing knew the 4 engine was dead and missed the boat as well with 747-8 other then they already had the fuselage
This has nothing to do with the 777. The few that did crash were not caused by the planes themselfs but by either weather or pilot error except for BA38 which was a fuel oil heat exchanger. As far the A380 it was built for hub to hub travel but Airlines and passangers wanted point to point. And the 747-8 was built primarly for a freighter verison rather then passanger if im not mistaken.
Passenger not Passanger sorry.
The manufacture designs and builds their products to a certain function and performance range their customers will buy. Regardless of what the end mission the aircraft performs, it must still be configured so that the flight characteristics fall within the design limitations the airworthynees certification was approved for. When it is modified or altered in anyway it no longer meets the airworthynees certificate issued by countries aviation officials and must either be recertified as experimental or brought back into compliance with the original airworthynees certificate.
In this case, when extra seats were installed in the rear of the aircraft, the added weight of seating and passengers, moved the center of gravity CG aft or towards the rear of the aircraft. By doing this it can make the aircraft pitch (up and down movement) uncontrollable, or not controllable enough to remain in the air, thus destroying the aircraft and most likely killing everyone aboard.
The pitiful part here, the whole exercise is about nothing more than money, the money that goes into their pockets in the form of profits. This is the same old lame story we have all heard many times before, it's a story a company and their profits vs the public at large and how many of us they can endanger before they cross the line and it kills a lot of us.
