Which outcome characterizes a jet engine during surging?

💡 Explanation

During surge, compressor stall causes reversed airflow due to insufficient pressure because some blades experience angles of attack above the critical level. Therefore, airflow becomes unsteady and reversed, rather than operating steadily; other options reflect normal, or optimized, turbine function.
