Factual narrative
DURING A LOCAL INSTRUCTIONAL FLIGHT, THE STUDENT PILOT ALLOWED THE GYROPLANE'S AIRSPEED TO GET TOO LOW DURING A SIMULATED EMERGENCY LANDING. AS A RESULT, THE GYROPLANE'S SINK RATE WAS TOO HIGH. THE FLIGHT INSTRUCTOR TOOK OVER AND ATTEMPTED TO INCREASE POWER, HOWEVER, SUFFICIENT AIRSPEED WAS NOT ATTAINED BEFORE A HARD LANDING WAS MADE.
