A320 Pre-flight Exterior Inspection/Walk Inspection/Walk Around
The purpose of the walk-around is to search for any conditions that could compromise the safety of the flight. It is important to perform this task correctly because the consequences of failure can be very serious. Never under-estimate the importance of performing a full and adequate external inspection, no matter how pushed for time you are or how much pressure you're under. Some incidents have occurred due to really obvious things that could have been spotted during the external inspection. A detailed table of walk-around procedures is as follows:
