NBAA CAM common mistakes
NBAA CAM · Understand the traps and how to avoid them.
Treating the CAM exam as a single-discipline test and studying only flight operations or only maintenance, skipping finance, insurance, and transactions entirely.
Candidates come from a specific role (chief pilot, DOM, scheduler) and naturally over-weight their comfort zone; the exam deliberately spans six domains with roughly even weight, so a strong operations score cannot rescue a weak finance or legal score.
What to do instead
Build a study plan mapped to all six domains with allocated hours per domain, and take a diagnostic quiz per domain before studying so time goes to the weakest areas rather than the most familiar ones.
Answering human-factors questions with the intuitive 'blame the individual' answer instead of the systemic SMS answer.
Line managers default to discipline and retraining as the remedy for error; CAM-style questions expect a systems view (error-prevention design, threat and error management, just culture, reporting without fear), so the intuitive answer is the distractor.
What to do instead
For every human-factors item, ask 'which option changes the system, procedure, or equipment rather than the person?' and practise justifying why the person-focused option is wrong.
Confusing the roles of the accountable executive, the safety manager, and the director of maintenance when answering SMS and IS-BAO questions.
The titles overlap in everyday speech, and many candidates work at organizations where one person wears several hats, so they answer from their own shop's practice rather than the standard's defined responsibilities.
What to do instead
Write a one-page role matrix (accountable executive holds ultimate authority and resources; safety manager administers the SMS and reports to the executive; DOM owns airworthiness) and answer every SMS item by locating the responsibility in that matrix.
Mixing Part 91 and Part 135 rules in the same answer, for example applying Part 135 duty-time limits to a Part 91 ferry flight or the reverse.
Many flight departments run both types of operation with the same aircraft and crews, so memory blurs which limit applies to which leg; candidates also forget that Part 135 limits are generally more restrictive and that some Part 91 subparts (like K) impose their own constraints.
What to do instead
Before answering any regulatory item, explicitly label the operation type and the rule part in your scratch notes, then check whether the question hinges on that distinction; drill mixed-set questions where the operation type changes between items.
Assuming a domestic understanding of operational control applies internationally, ignoring that the operator retains operational control even when using a foreign handler, broker, or contract crew.
Candidates equate 'someone else is doing it' with 'someone else is responsible,' and international supplement and permit requirements are less familiar than domestic rules because they come up rarely.
What to do instead
Study operational control as a non-delegable authority: list which functions (release, weather, alternates, crew legality, passenger manifest) stay with the certificate holder regardless of vendor, and review overflight and landing-permit lead times as a checklist item.
Treating the budget as a cost list and omitting variable hourly costs, reserves, and the difference between budget and actual cost per flight hour.
Candidates without finance background build a budget from fixed items (crew salary, hangar, insurance) because those are visible, and they underweight fuel, maintenance reserves, engine overhaul accruals, and trip-driven costs.
What to do instead
Build a cost model with three layers: fixed annual, hourly variable, and per-trip; then compute cost per flight hour under two utilization scenarios and explain how utilization changes the per-hour figure.
Answering aircraft transaction questions without separating the letter of intent, the purchase agreement, and the pre-buy inspection in the timeline and risk allocation.
Candidates know the documents exist but not which one binds the parties, where deposits become non-refundable, and how inspection findings trigger price adjustment or walk-away rights, so they pick an answer that sounds commercially sensible but misplaces the risk.
What to do instead
Draw the deal timeline with decision gates (LOI non-binding, deposit and escrow terms, pre-buy acceptance criteria, closing and title transfer) and for each gate note who bears the risk and what remedies exist.
Confusing hull, liability, and non-owned aircraft coverage when answering insurance scenarios, or assuming the policy responds to a loss it excludes.
Insurance questions are written as realistic scenarios and candidates reason from what 'should' be covered rather than from the coverage grant, so they miss named-insured gaps, pilot warranty clauses, and breach-of-warranty consequences.
What to do instead
For each scenario, identify the loss type first (physical damage to the aircraft, third-party bodily injury or property damage, or use of a non-owned aircraft), then match it to the coverage part and check the conditions that would void or reduce the claim.
Answering airworthiness items from general knowledge instead of the specific maintenance program, inspection, and record-keeping requirements that make an aircraft airworthy.
Experienced maintenance candidates rely on habit and paperwork they have always used, so they miss the distinction between airworthiness directives and service bulletins, or between required inspections and manufacturer recommendations.
What to do instead
Study airworthiness as a set of enforceable elements (type design conformity, AD compliance, required inspections, approved maintenance program, return-to-service sign-off, and records), and for each element write one sentence on what makes it mandatory.
Skipping the emergency response plan because it feels like a paperwork exercise, then missing questions on notification sequence, family assistance, and the interface with the SMS.
ERP questions look like common sense, so candidates do not study them, but the exam tests specific structure: who is notified, in what order, which roles activate, how the plan is tested, and how it feeds back into hazard identification.
What to do instead
Memorize the ERP skeleton (activation authority, command center, notification tree, media and family handling, preservation of records, post-event review) and practise describing how a tabletop exercise generates SMS corrective actions.
