Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately recalling the nine classes of dangerous goods and their subdivisions, with practical examples relevant to helicopter operations (e.g., Class 1 explosives for oil rig blasting, Class 3 flammable liquids for fuel).
- Expect demonstration of correct segregation and compatibility checking, particularly for explosives, referencing current IATA Dangerous Goods Regulations.
- Assess for clear understanding of helicopter-specific limitations, such as ban on certain items in single-pilot operations, or quantity thresholds for medical oxygen.
- Look for correct interpretation of UN numbers, proper shipping names, and hazard labels on multimodal packaging encountered in offshore/remote operations.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the specific edition of the IATA Dangerous Goods Regulations when citing rules, as amendments can affect helicopter operations, especially regarding battery-powered devices.
- 💡For practical assignments, systematically use a checklist approach when identifying dangerous goods: check UN number, class, division, compatibility group, and packing instruction.
- 💡Pay special attention to explosives carriage: show working of net explosive quantity calculations and demonstrate knowledge of the helicopter's particular loading restrictions (e.g., magazine separation from passenger cabin).
- 💡In written exams, use the exact terminology from regulations, such as 'overpack' for a container of multiple packages, and 'CAO' versus 'PAX' limitations for helicopter transport.
- 💡Always use correct aviation terminology in your answers, as this shows a professional understanding and earns marks.
- 💡When answering questions about procedures, structure your answer logically, step by step, to demonstrate a clear understanding of the sequence.
- 💡In calculations, always show your working and include units in your final answer to avoid losing marks for missing details.
Common Mistakes
Common errors to avoid in your coursework
- Students often confuse the term 'dangerous goods' with only obvious hazards like explosives, overlooking hidden items such as lithium batteries in medical equipment or survival gear.
- A frequent error is misclassifying ammunition as non-dangerous if it's for personal use, not realizing it falls under Class 1.4S explosive criteria.
- Misunderstanding the limitations of small quantity exceptions leads to assuming any small container can be carried without proper marking or documentation.
- Many learners incorrectly believe that labelling is optional if the item is listed on a shipper's declaration rather than recognising that all packaging must bear the appropriate hazard labels.
- Misconception: The helicopter crewman is only responsible for loading and unloading cargo. Correction: The crewman has a wide range of duties, including observation, communication, and assisting with navigation and safety.
- Misconception: Helicopters can fly in any weather condition. Correction: Helicopters have specific weather minima, and flying in adverse weather can be dangerous. Crewmen must be able to assess weather and make go/no-go decisions.
- Misconception: The pilot makes all decisions, and the crewman has no input. Correction: Effective CRM means that all crew members contribute to decision-making, and the crewman's observations and advice are vital.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A helicopter is tasked with a resupply mission to a forward operating base. The distance is 120 nautical miles, and the helicopter's average ground speed is 140 knots. Calculate the flight time in minutes. If the helicopter has a fuel endurance of 1 hour and 15 minutes, will it have enough fuel for the flight? Show your working.
- 1.Step 1: Identify the given facts: distance = 120 nm, ground speed = 140 kt.
- 2.Step 2: Use the formula: Time = Distance ÷ Speed. Time = 120 ÷ 140 = 0.857 hours.
- 3.Step 3: Convert hours to minutes: 0.857 × 60 = 51.4 minutes.
- 4.Step 4: Compare with fuel endurance: 1 hour 15 minutes = 75 minutes. Since 51.4 < 75, the helicopter has enough fuel.
Question: Describe the key components of a pre-mission brief for a helicopter crewman, and explain why each is important.
- 1.Step 1: Identify the key components: mission objectives, route, weather, threats, communications, and emergency procedures.
- 2.Step 2: Explain the importance of each: objectives ensure everyone knows the goal; route planning ensures navigation; weather affects safety; threats require defensive measures; communications enable coordination; emergency procedures prepare for contingencies.
- 3.Step 3: Conclude with the overall purpose: to ensure all crew members are informed and prepared for a safe and successful mission.
