Narrative:

We were practicing with my student a steep approach on a helipad. At the time of the incident; my student had around 20 hours of flight training. As he approached I notified his airspeed which was too fast; as he slowed down he lost his attitude with a nose up and his reaction was to input forward cyclic. We were below 300 feet and our rate of descent was too high; more than 1;300 FPM. We were diving and it was a warm day. I took the controls and I initiated a go around. As we stopped the descent and started to climb; I gave back the controls to my student and did my radio call to the tower. At the same time; I cleared my left side before to cross the runway 30 and there was an air carrier on rolling takeoff on the runway.it happened really fast; I deviated the course; checked if we were not converging and we cross the runway at 400 feet just above the air carrier.since [then] they have changed the procedures due to the complex airport.

Title: Robinson R22 instructor reported the student developed a high rate of descent during a steep approach so he/she took control and executed a go-around. Because of this airport's complex Class D airspace usage mix; the flight overflew the active runway with an air carrier aircraft on the takeoff roll.
