PNG CASA CPL Air Law common mistakes
PNG CASA CPL Air Law · Understand the traps and how to avoid them.
Answering questions about who may make, amend or disallow Civil Aviation Rules by assuming CASA PNG is the sole rule-maker, instead of distinguishing the Minister's power to make rules from CASA PNG's function of administering and enforcing them, and from the Minister's ability to disallow or override.
Candidates transfer the FAA/EASA mental model where the agency itself issues the technical regulations, then skim the Act's empowering provisions once and never revisit them. The PNG Act splits powers between the Minister and the Director/Authority in ways that are easy to blur.
What to do instead
Build a one-page 'who does what' table from the Civil Aviation Act: Minister (rule-making, directions, disallowance), CASA PNG/Director (issue, suspend, revoke, enforce, register aircraft, license personnel), and the courts/tribunal (appeals). For each practice question, first ask 'which body is named?' before reading the options.
Treating the PNG Civil Aviation Rules as a single undifferentiated document, so questions about applicability, definitions and compliance are answered from memory of a foreign rule set rather than from the CAR's own structure (Parts, definitions, and the general compliance provision that binds operators and persons to the rules).
The CARs are long and candidates memorise isolated numbers (e.g. fuel reserves, recency) without learning which Part contains them or how definitions like 'commercial air transport', 'operator' and 'pilot in command' drive applicability. They then apply a rule to an operation it does not cover.
What to do instead
Learn the Part map by number and subject, and for each operational rule you memorise, note the Part and the defined term that triggers it. Practise 'which Part applies' drills: given a scenario, name the Part and the definition that makes it apply, then answer.
Confusing CPL privileges and ratings with those of a PPL or ATPL, and misstating what a CPL holder may do without an additional rating (e.g. acting as PIC of a charter flight, instructing, or flying IFR), or misapplying recency and medical currency to the licence.
Privilege questions are written as scenarios and candidates answer from the licence title rather than from the precise privilege text, the class/type rating requirements and the recency and medical conditions attached to the licence.
What to do instead
Write out the CPL privilege statement, the ratings it does and does not include, and the recency/medical conditions as separate bullet points. For each scenario, check three gates in order: licence privilege, rating coverage, and current recency/medical - only then answer.
Answering registration and airworthiness questions by assuming the aircraft's foreign registration, foreign C of A or foreign maintenance approval remains valid for PNG operations, or that an aircraft can be operated on an expired C of A or without the required maintenance release/inspection.
Candidates carry over familiarity with N-registered or EASA-registered aircraft and forget that PNG registration and continuing airworthiness requirements (C of A validity, maintenance releases, approved maintenance arrangements) govern operations in PNG airspace.
What to do instead
Learn the registration and airworthiness chain as a sequence: eligibility and registration marks, issue and validity of the C of A, maintenance release before flight, and the conditions under which an aircraft is unairworthy. For each scenario, ask 'is this aircraft validly registered and airworthy under PNG rules right now?' before answering.
Getting flight-operations numerical and documentary questions wrong: fuel reserves and planning, performance/weight and balance, or required documents and equipment carried on board - often by recalling a figure from another jurisdiction (e.g. 30 minutes vs 45 minutes hold) or by forgetting which documents must be on board.
Fuel, performance and documents are memorisation-heavy and candidates learn numbers without the conditions attached (day/night, IFR/VFR, turbine/piston, destination alternate required or not). Numbers learned without conditions are recalled incorrectly under pressure.
What to do instead
For every fuel and performance figure, write the condition set beside it (operation type, day/night, IFR/VFR, alternate). Memorise the on-board document and equipment list as a checklist and rehearse it against three scenarios: VFR day, IFR night, and commercial air transport.
Misclassifying airspace and misapplying VFR/IFR weather minima, clearance requirements and the difference between controlled and uncontrolled airspace, so questions about whether a clearance is required, or what minima apply, are answered using the wrong airspace class.
Candidates memorise a single set of VFR minima and apply it everywhere, ignoring that minima and clearance requirements vary with airspace class and with control zone/control area status. They also confuse 'clearance' with 'information' in Class G.
What to do instead
Draw the PNG airspace classes with their VFR minima, clearance and ATC service requirements in a grid. Practise classifying a location and flight condition first ('what class, what rules?'), then apply minima. Learn that in Class G no clearance is issued but see-and-avoid and right-of-way rules still apply.
Answering aerodrome and ground-operations questions from general knowledge rather than from the specific visual aids, markings, signs, lighting and ground-movement rules - e.g. misreading runway holding position markings, taxiway markings, or the meaning of aerodrome lighting and wind indicators.
These questions are visual and detail-based, and candidates who have not studied the aid/marking system rely on vague impressions. They also confuse aerodrome operating minima with visual-aid questions.
What to do instead
Study each marking, sign and light by function (runway, taxiway, holding position, displaced threshold, wind direction indicator) and test yourself with verbal descriptions rather than pictures. Link each aid to the ground rule it supports (e.g. holding short of a runway).
Confusing communication, navigation and surveillance requirements - mixing up which services and equipment are required for which operation, or misunderstanding clearance readback, position reporting and lost-communication procedures.
CNS content overlaps with flight rules, and candidates learn equipment lists without linking them to the operation (IFR vs VFR, controlled vs uncontrolled). Readback and lost-comm procedures are memorised as phrases rather than as decision sequences.
What to do instead
Build an equipment-requirement matrix by operation type and airspace, and rehearse lost-communication and readback procedures as step sequences (what you do, in what order, and what you expect ATC to do). Answer CNS questions by naming the operation first.
Treating accident and incident notification as interchangeable, or naming the wrong body and timeframe - e.g. notifying CASA PNG when the PNG AIC is the investigating authority, or missing the immediate notification requirement and the distinction between an accident and a serious incident.
Candidates learn 'report it' without learning the definitions, the notifying authority, the timescale and the preservation-of-evidence duty. The PNG AIC Act framework is often studied only superficially.
What to do instead
Write the definitions of accident, serious incident and incident side by side, then a notification flow: who notifies, whom, how quickly, and what must be preserved. Practise classifying three scenarios and naming the correct authority and timeframe for each.
Assuming ICAO Annex standards apply automatically and identically in PNG, or conversely ignoring them - e.g. answering Chicago Convention or Annex questions as if PNG had no differences, or failing to apply Annex-based standards (dangerous goods, security, environment) where PNG rules incorporate them.
Candidates either treat ICAO Annexes as directly binding law or dismiss them as irrelevant, missing that PNG implements them through its own Act and Rules, with filed differences. Dangerous goods, security and environmental questions are then answered from general impressions.
What to do instead
Learn the chain: Chicago Convention obligations → PNG Act and Rules implementing them → any notified differences. For dangerous goods, security and environment, memorise the specific PNG rule requirement and the Annex it derives from, and check whether a difference is relevant before answering.
