Guided Scenario(s)

  • During a planned helicopter flight, conditions require the student to apply the knowledge and procedures associated with low rotor revolutions per minute (rpm) recognition and recovery.
  • Ask the student to identify hazards, including Powerplant limitations, and explain how each risk will be controlled.
  • Require the student to brief, perform, or explain how to Complete the appropriate checklist(s), as appropriate to the task and training environment.
  • Introduce a realistic change in wind, power available, landing area, traffic, system status, or external pressure and require the student to reassess the plan.
  • Conclude with a self-critique tied to the ACS knowledge, risk management, and skill elements.
