I have noticed that the CRJs are 'chatty', but are these normal ACARS Maintenance faults one should see during a flight? (these are all from the same flight which I redacted the flight info) Things like the radar altimeter being off, the air data computers not in agreement, a flight data recorder? showing a fault, and the electrical power generator 1 needing maintainance. Am I over reading too much? Are these just normal squawks crews see everyday?
