Detecting the ‘small’ damage ◦ Accuracy <1mm resolution (missing rivets, dents, holes) ◦ Repeatability
Doing it safely ◦ Operating close enough to the aircraft ◦ People (passenger, aircrew, ramp staff) ◦ Aircraft (movements, engines running etc) ◦ Regulation
Doing it without a significant training burden ◦ Automated Operation ◦ Reduce Close/Direct Visual Inspections
Building confidence ◦ Can sensor based data replace ‘hands on’ engineering
inspection?
