CAA NZ PPL Air Law common mistakes
CAA NZ PPL Air Law · Understand the traps and how to avoid them.
Quoting a rule number (e.g. 'Part 91 says...') as the whole answer when the question asks what the pilot must actually do in a given situation, without stating the obligation, the condition, and who it applies to.
Candidates memorise Part numbers and subpart headings from the CAA rule website index but never read the actual rule text, so they can name the part but cannot reproduce the duty it imposes. Exam questions are scenario-based and reward the operative requirement, not the citation.
What to do instead
For each core rule you study (fuel and oil, pre-flight action, weather minima, documents to be carried, maintenance responsibility), write one sentence in the form 'The pilot in command must [action] before/when [condition]'. Test yourself by covering the rule number and reciting the obligation. Use the rule number only as a memory hook, never as the answer.
Treating an Advisory Circular as if it were a rule, answering 'the AC requires...' when the AC only describes an acceptable means of compliance.
ACs are written in the same imperative tone as rules and are often easier to find and read than the rule itself, so candidates absorb the AC wording and assume it is binding. The exam deliberately tests whether you know the hierarchy.
What to do instead
Learn the hierarchy explicitly: Act, then Civil Aviation Rules (binding), then ACs and acceptable means of compliance (advisory), then AIP and other operational publications. When you read an AC, find the rule it supports and note 'AC = one acceptable way; the rule is the requirement'. Practise classifying statements as binding or advisory.
Assuming all controlled airspace is the same, and applying the Class C clearance and communication requirements inside Class D airspace, or expecting a clearance in Class G.
Candidates learn 'controlled airspace needs a clearance' as a single fact and never build the class-by-class table of services, clearances, and VMC minima. The distinctions between Classes C, D, and G are the most heavily examined airspace content.
What to do instead
Build a one-page grid with rows for Class C, D, and G and columns for: ATC clearance required, two-way radio required, traffic information provided, separation provided, and VMC minima. Fill it from the AIP and rules, then redraw it from memory until accurate. Attach one concrete scenario to each cell (for example, transiting a Class D CTR).
Reading the AIP as a narrative and missing that the answer is in a specific document type (an aerodrome chart, a departure and approach chart, or a supplement), or using an out-of-date AIP amendment.
Candidates download the AIP once, skim it, and never learn its structure or the amendment cycle. In the exam, questions are framed around where a piece of information lives and whether it is current, and candidates cannot place the information.
What to do instead
Learn the AIP structure deliberately: which volume or section holds aerodrome data, which holds airspace and routes, and where supplements and amendments sit. Note the effective date and amendment number on anything you study. Practise 'where would I find X?' drills for ten common items such as runway declared distances, CTR boundaries, and noise abatement procedures.
Mixing up the validity periods and privileges of different licence types and ratings, for example assuming a PPL holder may act as pilot in command on an aircraft requiring a type rating without holding that rating, or confusing medical validity with licence validity.
Licence, rating, and medical validity are three separate clocks, and candidates collapse them into one 'my licence is current' idea. The rules set them independently, so the trap is assuming one renewal covers all three.
What to do instead
Make a table with three columns: licence, ratings, and medical certificate. For each, record what is required to exercise privileges, the validity period, and what happens on lapse. Then answer practice questions by naming which of the three clocks the question is really about before choosing an answer.
Treating the medical certificate as valid for all operations once issued, ignoring that the class of medical and any limitations or conditions attach to the privileges being exercised.
Candidates focus on passing the medical and never read the conditions printed on the certificate or the rule linking medical class to licence privileges. Scenario questions about a pilot with a limitation, or about a change in medical status, then catch them out.
What to do instead
Read the conditions and limitations section of a sample medical certificate and match each to the privileges it restricts. Learn what a pilot must do when a medical condition arises or a medication is started, and who decides fitness to fly. Practise questions that give a pilot's medical class and ask which operations are permitted.
Deciding that an occurrence is not reportable because 'nothing happened' or because the pilot handled it, and therefore not identifying the reporting obligation or the time frame.
Candidates equate reportable with serious, so near misses, runway incursions, and technical defects that were resolved in flight get filed mentally as non-events. The rules define reportable occurrences by category, not by outcome.
What to do instead
Learn the categories of reportable occurrence and the distinction between mandatory reporting and voluntary disclosure. For each category, note who reports, to whom, and within what time. Then run five short scenarios and decide reportable or not, and why, writing the category name each time.
Answering command-and-responsibility questions by deferring to ATC or to the operator, for example 'the pilot must follow the clearance' without recognising that the pilot in command remains responsible for the safety of the aircraft.
Training emphasises compliance with clearances and instructions, so candidates internalise obedience as the primary duty and forget the overriding responsibility of the pilot in command, including the duty to refuse or query an unsafe clearance.
What to do instead
For every question involving a clearance, a defect, or a passenger, ask 'who is the pilot in command and what is that person's final responsibility?' Learn the specific duties attached to command (pre-flight action, ensuring documents, deciding on unserviceabilities) and practise scenarios where the correct answer is to query or decline rather than comply.
Memorising VMC and cloud-clearance numbers without the conditions attached to them, such as whether the airspace is controlled, the altitude band, or whether a clearance is held, and then applying the wrong set.
The minima appear as bare number tables in study notes, so candidates learn the numbers and drop the qualifiers. Exam questions almost always supply the qualifier and expect you to select the matching row.
What to do instead
Rebuild the table from the source with every qualifier as a column heading: airspace class, altitude, and control status. Then answer questions by first writing down the qualifiers from the stem, then looking up the row. Never answer a minima question from memory alone until you can reproduce the table with its headings.
Studying only the rule parts that feel like flying (flight rules, licensing) and skipping the parts on certification, maintenance, and organisational responsibilities, then guessing on questions drawn from them.
Candidates prioritise what they use day to day and treat the regulatory-framework parts as background. The exam samples across the whole syllabus, so whole rule parts become blind spots.
What to do instead
Map the syllabus to rule parts and mark your confidence for each part on a three-point scale. Study the lowest-scoring parts first, reading the purpose statement and key definitions of each. Aim for working knowledge of every part in the syllabus rather than deep knowledge of a few.
