    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always follow maintenance manuals.
    • 💡Practice interpreting engineering drawings.
    • 💡Know the different types of rivets and their uses.
    • 💡Memorise common rivet types and their applications.
    • 💡Practice interpreting engineering drawings with limits and fits.
    • 💡Review safety procedures for handling adhesives and sealants.
    • 💡Familiarise yourself with common aircraft rivet types and their applications.
    • 💡Practice reading engineering drawings with limit and fit annotations.
    • 💡Understand the importance of safety when using workshop tools.
    • 💡In practical assessments, always cross-reference the task with the relevant aircraft maintenance manual or standard practice document.
    • 💡When answering written questions on adhesives, mention specific product designations and cure cycles where applicable.
    • 💡For drawing interpretation tasks, systematically check the title block, revision status, and tolerance blocks before measuring.
    • 💡In structural replacement scenarios, emphasize the importance of corrosion protection and post-installation inspections.
    • 💡Use correct terminology (e.g., pitch, edge distance, squeeze force) when describing riveting to gain full marks in technical assessments.
    • 💡Always show your working in calculations, even if you think the answer is obvious. Marks are awarded for method, not just the final answer.
    • 💡When answering questions about materials, link properties to applications. For example, explain why aluminium is used in aircraft (lightweight, corrosion-resistant) rather than just listing properties.
    • 💡Use technical vocabulary accurately. Terms like 'tensile strength', 'fatigue', and 'conductivity' should be defined and used in context to demonstrate understanding.

    Common Mistakes

    Common errors to avoid in your coursework

    • Using incorrect tools or damaging components.
    • Misreading tolerances on drawings.
    • Applying sealant incorrectly leading to leaks.
    • Using incorrect tools or applying excessive force, causing damage.
    • Misreading drawing tolerances, leading to improper fits.
    • Failing to follow correct bonding procedures, resulting in weak joints.
    • Using incorrect tools for specific tasks.
    • Misreading tolerances on engineering drawings.
    • Applying adhesives without proper surface preparation.
    • Failing to account for tool calibration expiry dates, leading to non-compliance with airworthiness regulations.
    • Misinterpreting drawing tolerances, resulting in parts that fit incorrectly or are rejected during inspection.
    • Applying adhesives or sealants without proper surface preparation, causing bond failure or corrosion.
    • Confusing rivet type codes (e.g., AN470, MS20470) or using incorrect rivet length for the grip range.
    • Overlooking mandatory structural support or sequence requirements during component removal, risking airframe damage.
    • Misconception: 'Engineering is all about maths and doesn't require creativity.' Correction: Engineering involves creative problem-solving and design innovation, not just calculations.
    • Misconception: 'All metals are equally strong.' Correction: Strength varies widely; for example, aluminium is lighter but weaker than steel, and heat treatment can alter properties.
    • Misconception: 'Electrical circuits are too complex to understand without advanced maths.' Correction: Basic circuit analysis uses simple algebra and Ohm's law; complex maths is not required at this level.
