Learning Objectives
What you need to know and understand
- Assist the pilot in maintaining aircraft control solely by reference to flight instruments during instrument meteorological conditions.
- Apply standard operating procedures for procedural instrument flying to ensure precise navigation and communication.
- Carry out reversionary night flying duties, including monitoring instruments and exterior lighting conditions.
- Execute correct emergency response drills during simulated instrument or night flight scenarios.
- Operate night vision goggles to enhance visual capabilities while maintaining cockpit discipline.
- Coordinate with the pilot using effective crew resource management techniques to mitigate risks during low-visibility operations.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly identifying instrument failures and communicating them to the pilot without delay.
- Assess the learner's ability to perform a systematic scan of instruments during simulated IMC, as per checklist.
- Look for appropriate use of night vision goggles, including pre-flight checks and in-flight adjustments.
- Evidence of calm and structured communication during emergency drills, adhering to standard phraseology.
- Demonstration of accurate altimeter setting and heading changes as directed by the pilot during procedural instrument flying.
Assessment Guidance
Guidance for achieving higher grades
- 💡Practice instrument scan patterns regularly to build habit, ensuring rapid fault detection.
- 💡During night flying exercises, prioritize clear and concise radio calls to avoid confusion.
- 💡For emergency drills, verbalize actions as you perform them to demonstrate understanding to the assessor.
- 💡Familiarize yourself with the helicopter's specific NVG limitations and procedures prior to assessment.
- 💡Use crew resource management principles to show proactive support, such as anticipated callouts.
- 💡Always use correct aviation terminology, such as 'MTOW', 'payload', and 'CRM', to demonstrate your knowledge.
- 💡In scenario-based questions, structure your answer logically: identify the issue, apply relevant principles, and conclude with a clear outcome.
- 💡Practice calculations involving weight and balance, as these are common in exams and require precision.
Common Mistakes
Common errors to avoid in your coursework
- Failing to cross-check instruments, leading to spatial disorientation.
- Over-reliance on night vision goggles without maintaining instrument scan.
- Misidentifying emergency procedures, such as incorrect response to an engine fire drill.
- Poor communication timing, causing distraction to the pilot during critical phases of flight.
- Misconception: The crewman is a backup pilot. Correction: The crewman is not trained to fly; they manage the cabin and assist with navigation and observation.
- Misconception: Weather has little impact on helicopter operations. Correction: Weather is a critical factor; it affects visibility, payload, and safety, and must be carefully monitored.
- Misconception: Mission planning is only about the route. Correction: It includes fuel, weather, emergency landing zones, and coordination with ground units.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A helicopter is required to transport 4 crew members (each 85 kg) and 200 kg of cargo. The helicopter has a maximum take-off weight (MTOW) of 2,500 kg and an empty weight of 1,200 kg. Fuel weighs 300 kg. Calculate the total payload and determine if the helicopter is within MTOW limits.
- 1.Step 1: Calculate total crew weight: 4 × 85 kg = 340 kg.
- 2.Step 2: Calculate total payload: crew weight + cargo = 340 kg + 200 kg = 540 kg.
- 3.Step 3: Calculate total take-off weight: empty weight + payload + fuel = 1,200 kg + 540 kg + 300 kg = 2,040 kg.
- 4.Step 4: Compare with MTOW: 2,040 kg < 2,500 kg, so the helicopter is within limits.
Question: Describe the key elements of a pre-flight safety brief for a helicopter crewman, and explain why each is important.
- 1.Step 1: Identify the main elements: emergency procedures, roles and responsibilities, communication protocols, and safety equipment.
- 2.Step 2: Explain emergency procedures: knowing how to react to engine failure, fire, or ditching is critical for survival.
- 3.Step 3: Explain roles: each crew member must know their specific tasks to ensure efficient and safe operation.
- 4.Step 4: Explain communication: clear communication prevents misunderstandings and enhances coordination.
- 5.Step 5: Explain safety equipment: familiarity with life vests, first aid kits, and fire extinguishers ensures readiness.
