can you imagine bieng in the room when they saw a problem with the weight/balance software?, planes in the air!
realy realy hope this was a false positive or a reporting glitch, rather than ANY flaw in what was shown to pilots
W/B is something calculated before takeoff and wouldn't affect planes already in the air or with the W/B already loaded into the FMS.
But what if incorrect values have been loaded? I think the biggest risks are indeed during takeoff, but I'm not sure if there are no others at all.
i assume it would be within bounds during “normal” atmospheric conditions. In the air with the wrong data and extreme conditions would be where it gets dicey?
Incorrect w&b can affect a lot of things. From longer ground roll during landing, to wrong brake settings, to worse handling of the aircraft and increased stall speeds. Under normal circumstances it should not be a problem due to huge safety margins, but if other things go wrong it starts adding up. One more hole in the swiss cheese model.
I presume planes are in the air any time a problem is discovered with any system.
