Airplane engines get a heater to stop freezing at high altitudes
What happened
The FAA wants to update rules for certain CFM International jet engines. This update requires replacing software, wiring, and a pressure sensor with a new heated version. This change prevents ice from forming on the sensor, which could cause engine problems.
Why it matters
Planes flying at high altitudes sometimes have sensors freeze up, which can lead to engine issues. This rule change means a specific part of the engine, the pressure subsystem, will now be heated. This makes those engines more reliable in cold conditions, reducing the risk of unexpected engine problems during flight.
The signal
Watch for the final rule to be published and then for airlines to schedule the required maintenance and part replacements for their affected aircraft.
