Today's IERW helicopter fleet includes 154 Bell TH-67 Creeks--109 configured for basic "contact" training and 45 for instrument training.
The current single-track training syllabus follows 32 weeks of IERW training with a six- to 14-week Aircraft Qualification Course (AQC) on modern operational aircraft.
In the late 1980s, the Army instituted a successful multi-track IERW scheme where students streamed from light training helicopters to their go-to-war aircraft.
The Flight School XXI concept revives the multi-track IERW scheme.
The new training plan blends the aircraft qualification course into IERW to shorten the overall program, but it gives students more time in their operational aircraft.
