Airbus planes must install a software fix for a radio problem
What happened
The US aviation regulator now requires a software update for certain Airbus A319, A320, and A321 airplanes. This update fixes a radio data synchronization problem and applies to more aircraft models.
Why it matters
Aircraft operators previously relied on flight manual instructions to manage a radio problem. Now, they must install a software modification to prevent the problem from happening. This shifts the burden from pilots reacting to a fault to a permanent technical fix.
The signal
Watch for any reports of delays in installing the software update, or if the new fix introduces unforeseen issues.
