Dassault Falcon 7X airplanes get a mandatory fix for unreliable flight data

The US aviation regulator is proposing to update an existing rule for certain Dassault Falcon 7X airplanes. This update would require owners to modify the avionics system to fix a weak point that can cause unreliable flight data.

Aviation regulators issue these directives when a safety issue is found in an aircraft design. This proposed rule means that a known problem with flight data on these specific planes will now be permanently fixed, rather than just managed through emergency procedures. It shifts the burden from pilots having to react to faulty data to the manufacturer having to prevent it.
