CAA NZ Flight Instructor Theory - Instructor Air Law common mistakes
CAA NZ Flight Instructor Theory - Instructor Air Law · Understand the traps and how to avoid them.
Treating the instructor rating as a blanket authority to teach anything, sign any student off, or fly any aircraft, instead of checking the specific rating, endorsement and aircraft type on the licence.
Candidates memorise 'instructor' as a single privilege and skim the Part 61 rating and endorsement structure, so they miss that privileges attach to categories, classes, types and specific endorsements, and that some activities (for example certain solo authorisations or type-specific training) need separate authority.
What to do instead
Build a one-page matrix of instructor privileges: for each rating and endorsement, write what it authorises, what it does not, and what additional endorsement or approval is needed. Practise scenario questions by asking 'which specific rating or endorsement does this act require?' before answering.
Authorising a student's first solo or a solo flight without confirming every prerequisite is met and documented, such as the required pre-solo written and oral checks, medical validity, and the instructor's own current competence to supervise.
Candidates remember the broad idea that an instructor authorises solo flight but not the layered conditions, so they answer as if a single sign-off covers everything, ignoring currency, medical validity and record-keeping that must exist before the authorisation is valid.
What to do instead
Write out a pre-solo checklist in the order it must be completed and test yourself on which items are the instructor's responsibility, which are the student's, and which must be recorded and where. For scenario questions, list each condition and eliminate answers that skip any one of them.
Confusing accident and incident definitions and misapplying the notification duties, for example not notifying when an occurrence caused serious injury or substantial damage, or notifying the wrong body within the wrong timeframe.
The two definitions overlap in everyday language, and candidates rely on intuition rather than the rule-based tests (injury severity, aircraft damage thresholds, operational disruption), so they misclassify occurrences and then pick the wrong notification path.
What to do instead
Memorise the statutory tests as a decision tree: does it meet the accident threshold, if not does it meet the incident threshold, and who must be notified and when. Work through ten short occurrence vignettes and classify each, writing the reason next to your answer.
Answering minimum safe altitude and VFR meteorological minima questions from memory of a single figure, without distinguishing whether the flight is over a congested area, over water, in controlled or uncontrolled airspace, or at a licensed aerodrome.
These rules have several context-dependent values, and candidates learn one headline number, then apply it to every scenario. The exam deliberately sets questions in different contexts to test whether the candidate knows which rule applies.
What to do instead
Create a table with rows for congested area, other areas, aerodrome traffic, and controlled versus uncontrolled airspace, and columns for altitude and visibility and cloud clearance. Fill it from the rules, then redrill until you can reproduce it from memory and state which cell a scenario falls into.
Assuming an airspace classification grants or withholds a clearance automatically, for example treating entry into controlled airspace as permitted because the class is 'less restrictive', or misjudging special VFR conditions.
Candidates learn airspace classes as a list of letters and services rather than as a set of entry, clearance and equipment requirements, so they cannot map a class to what the pilot must do before and during entry.
What to do instead
For each class, write the entry requirements, clearance requirement, radio and transponder requirements, and VMC minima in one grid, and practise questions by first identifying the class and then reading the requirement from the grid rather than guessing.
Treating the certificate of airworthiness, the maintenance programme and the daily inspection as interchangeable, and answering defect-reporting questions as if any defect can simply be deferred or recorded informally.
The documentation chain feels administrative, so candidates learn the document names without learning what each one authorises, who signs it, and what happens when a defect is found, leading to errors on airworthiness and defect-reporting questions.
What to do instead
Map the chain from certificate of airworthiness to maintenance programme to maintenance release to defect recording, noting who may certify each step and what the aircraft's status is at each stage. Drill defect scenarios by asking whether the aircraft may fly, who decides, and what must be recorded.
Mixing up mass and balance responsibilities, such as assuming the loading system or the operator computes the figures when the rule places the responsibility on the pilot in command, or ignoring that maximum mass limits apply separately to different configurations.
Candidates treat mass and balance as a calculation exercise rather than a regulatory duty, so they focus on arithmetic and miss the accountability and documentation requirements that the exam is testing.
What to do instead
Write a short statement of who is responsible for what in mass and balance, then list the separate limits (maximum take-off, landing, zero fuel where applicable) and the documentation each flight needs. Practise questions by locating the responsibility before doing any numbers.
Applying human factors limits loosely, for example treating the alcohol limit as a matter of judgement, ignoring the duty to assess fatigue and fitness before flight, or failing to consider the instructor's supervisory duty of care to a student.
These topics feel like general good practice rather than hard rules, so candidates answer with the sensible-sounding option instead of the specific limit, timeframe or obligation in the rule, and miss questions that hinge on a precise threshold or a duty to act.
What to do instead
Learn the specific limits and timeframes as exact figures with their units, and pair each with a short scenario showing how it is breached. For duty-of-care questions, ask which person owes the duty, to whom, and what action the rule requires, then choose the answer that names that action.
Answering dangerous goods and security questions by common sense, such as assuming an item is allowed because it is not obviously hazardous, or assuming screening rules apply only to checked baggage.
Candidates have no operational exposure to dangerous goods and security screening, so they reason from everyday experience rather than from the carriage, acceptance and screening rules, and pick plausible but wrong answers.
What to do instead
Learn the categories of dangerous goods, who is responsible for acceptance and carriage, and the passenger and crew restrictions, plus the screening and restricted-article rules for both cabin and hold. Practise by classifying a list of common items and stating the rule that decides each.
Confusing advisory material with the rule itself, for example citing an advisory circular or acceptable means of compliance as if it were a binding requirement, or vice versa assuming a rule does not apply because no guidance mentions it.
Candidates see advisory circulars quoted alongside rules in study material and lose track of the hierarchy, so they cannot tell which document creates an obligation and which merely describes an acceptable way to meet it.
What to do instead
Draw the hierarchy explicitly: Act, then rules, then advisory material and acceptable means of compliance, with an arrow showing that guidance explains but does not create the obligation. For each practice question, state which level of document the answer comes from before selecting it.
