The next task for NF-15B was the High Stability Engine Control (HISTEC) research program. This experiment, developed and managed by NASA’s Lewis Research Center, evaluated a computerized system that could sense and respond to high levels of engine inlet airflow turbulence to prevent sudden in-flight engine compressor stalls and potential engine failures.

Approximately a dozen flights were flown in the summer of 1997 to validate the HISTEC concept.
