• The AIM is a program for routine in-flight recorded data analysisto detect abnormal on-board systems conditions and/or adversetrends.
• The AIM also has the goal to support and enhance the processof the in-service technical difficulties investigation and follow upthe effectiveness of the respective Embraer corrective actions.
• The source of data for AIM can be FDR/QAR.

Aircraft Integrity Monitoring is not FOQAThe AIM does not have the goal to detect or identify operational deviations or to monitor the flight crew performance.
AIM is not FOQA
AIM – Aircraft Integrity Monitoring
AIM is construed in a manufacturer-to-operator non disclosure agreement and its scope is to enhance safety. AIM is protected to be used against any disciplinary action to a crew member.

Hard Landing
A hard landing is a high energy runway contact. The NTSB defines hard landing as "stalling onto or flying into a runway or other intended landing area with abnormal high vertical speed"
