+# Modify activated flight test step
+
+This page describes the content of a common test case where a valid user flight intent in activated state should be
+successfully modified by a flight planner.  See `modify_activated_flight_intent` in [test_steps.py](test_steps.py).
+
+## Successful modification check
+
+All flight intent data provided is correct and valid and free of conflict in space and time, therefore it should have
+been modified by the USS per **interuss.automated_testing.flight_planning.ExpectedBehavior**.
+If the USS fails to modify the flight, wrongly indicates a conflict, or wrongly indicates the activated state of the
+flight, this check will fail.
+
+## Failure check
+
+All flight intent data provided was complete and correct. It should have been processed successfully, allowing the USS
+to reject or accept the flight. If the USS indicates that the injection attempt failed, this check will fail per
+**[interuss.automated_testing.flight_planning.ExpectedBehavior](../../requirements/interuss/automated_testing/flight_planning.md)**.
