Threat and error management question
Got my ATPL Human factors exam tomorrow. Saw the following example question on another forum but couldn't find an answer anywhere.
A pilot uses an out of date chart and inadvertently flies the aircraft towards CTA, which is the error:
a) Using the out of date chart
b) Flying the aircraft towards CTA
Couldn't figure this out, would you consider the aircraft flying towards CTA as an undesired aircraft state rather than an error?
Be grateful for any help,
J
