Depends on the input. Some continuously variable inputs can be as low as one sample per second.
This kind of low resolution is not an equipment limitation, it is per approved and certificated design. Regulatory bodies (FAA, JAA) pressed to widen data collection parameters aboard commercial airliners back in the 1990s. Certain manufacturers resisted citing cost,complexity and
data reliability issues with these retrofit systems. An imperfect compromise is what we have today.
hmmm, me it seems that you guys don't really have a solid information on how flight data monitoring happens in a modern airline. The data in question doesn't go on the desk of chief pilot, maintenance or even dispatch
One hopes that the majority will always follow this excellent example of the ideal. The reality, however, can be different. Once data is gathered and recorded, the home office owns it and can mine at will the entire collection for whatever suits their purpose du jour.
This information in the right hand is an enormous increase in safety.
Happy flying,

Of this there can be no doubt.
