Try yourself as a co-pilot! Don't let down your crew! Take-off the plane. Pass through all the stages of descent and approach procedures by inaccurate scheme - with using radio NDB's. You have an experienced captain and mechanic, they'll tell you all shortcomings. All the faults will be reported in the post-flight analysis. Make a soft landing, and try not to break the plane! Warning: Successful completion of all stages of the simulation does not give you the right to operate an aircraft! Training and experience of a real pilot is much broader than any amateur ones.
