Instrument Rating IR(A) common mistakes

Instrument Rating IR(A) · Understand the traps and how to avoid them.

Mistake 1

Treating the instrument rating as an add-on with its own standalone hour requirement, quoting a fixed number of instrument flight hours for the initial IR(A) without linking it to the total flying experience the applicant must already hold and to the cross-country PIC time that must be flown under instrument flight rules with an appropriately qualified pilot.

Candidates memorise the headline instrument-hour figure from a training syllabus and never rebuild the full eligibility picture from the regulation; the requirement is a package (total time, PIC cross-country time, instrument time, and a qualifying instrument cross-country flight), and exam items routinely probe one component while the candidate answers with another.

What to do instead

Build a one-page eligibility matrix for the initial IR(A) with a row per component (total time, PIC time, instrument instruction time, instrument time in the type, cross-country instrument flight) and a column for the regulatory reference. For each row write the number, the conditions attached to it, and how it can be credited. Recite the matrix from memory weekly and answer every practice item by naming the row being tested before choosing the figure.

Mistake 2

Assuming that holding a valid IR(A) on one aircraft category automatically confers instrument privileges on another category or on a multi-engine class, or that a proficiency check on a single-pilot aeroplane extends privileges to multi-crew operations.

The rating is granted per category and, where relevant, per class or type, and the privileges attach to the licence plus the rating plus the class/type endorsement; candidates flatten this hierarchy into 'I have an IR' and then misjudge what a check ride actually renewed.

What to do instead

Draw the licence-to-privilege chain explicitly: licence, category, class/type endorsement, IR, and any operational limitation (single-pilot, multi-crew, single-engine). For each combination write whether instrument privileges exist and which document evidences them. Practise by taking a scenario (for example, IR(A) held on a single-engine land aeroplane) and stating what is required before flying an instrument approach in a multi-engine type.

Mistake 3

Conflating the validity period of the instrument rating with the recency requirements for recent experience, and answering questions about revalidation as if the only thing that matters is passing a proficiency check before the rating expires.

Two different clocks run in parallel: the rating's validity and the recent-experience rule that gates actual IFR flight. Candidates who learn only the check-ride interval miss that recent experience can lapse well before validity, and vice versa, and they mis-handle the case where the check is taken in the final months of validity.

What to do instead

Keep two separate timelines on one page: rating validity and its renewal/revalidation windows, and the recent-experience window with its specific instrument tasks. For each timeline write the trigger event, the permitted window, and the consequence of missing it. Work through edge cases: check taken early in the validity period, check taken after expiry, and recent experience regained without a full check.

Mistake 4

Describing the skill test or proficiency check as a single pass/fail event and ignoring the section-by-section structure, the tolerances applied to each manoeuvre, and the rule that failing one section ends the test while a partial pass may still credit completed sections within a defined period.

Candidates prepare by flying the manoeuvres and reading a summary of the test, not the examiner's standardisation material; they therefore cannot answer items about what happens after a discontinued or failed test, or about which sections must be repeated.

What to do instead

Reconstruct the test structure as a table: section number, manoeuvres, tolerance, and the consequence of a failure in that section. Add a decision tree for outcomes (pass, partial pass, fail, discontinued) with the time limits for completing the remainder. Learn the tolerances as numbers with units and practise stating them without notes.

Mistake 5

Treating examiner standardisation as a formality and being unable to state what standardisation actually controls: the uniformity of test conduct, the calibration of examiner judgement, and the mechanism by which an examiner's authorisation is granted, extended, or withdrawn.

Standardisation material is read once during examiner training and candidates for the IR(A) assume it is examiner-only knowledge; but the licensing domain tests the candidate's understanding of how the test they will take is kept fair and consistent.

What to do instead

Write a short explanation of the standardisation loop: initial examiner training, oversight of conducted tests, refresher activity, and removal of authorisation for cause. For each stage note who is responsible and what evidence is recorded. Link it back to the candidate's own test: which parts of the test are examiner-discretion and which are fixed by the standard.

Mistake 6

Answering medical-fitness items by recalling a single validity duration for the class of medical certificate, without distinguishing the validity period from the conditions that can shorten, suspend, or invalidate it, such as a change in medical condition, pregnancy, or a significant clinical event.

The validity table is the easiest thing to memorise, so candidates stop there; the regulation also imposes a duty on the holder to seek advice and to stop exercising privileges when unfit, and that duty is what exam items are usually about.

What to do instead

For each class of medical certificate, tabulate: validity duration, the age bands that alter it, who may extend it, and the events that require a new examination or a specialist assessment. Separately write the holder's obligations in three sentences. Test yourself with scenarios (new medication, hospital admission, change of category) and state the action and the timeframe.

Mistake 7

Assuming that a medical certificate issued in one State is automatically accepted for all privileges without considering the limitation codes, the possibility of a certificate issued with a restriction, or the requirement for a second assessment when privileges are exercised in another State.

Candidates think of medical certification as binary fit or unfit and do not study the coding of limitations or the conditions under which a certificate can be validated elsewhere; exam items exploit exactly this gap by describing a pilot with a restriction code.

What to do instead

Learn what a limitation code does operationally: it narrows the privileges the medical certificate supports and must be read together with the licence. Write a short list of typical restriction categories and, for each, the operational consequence. Then write the rule for exercising privileges abroad and the circumstances requiring additional assessment.

Mistake 8

Confusing the roles of the aeromedical examiner and the licensing authority in the fitness assessment, for example stating that the examiner decides the final outcome on a complex case or that the authority conducts the routine examination.

In day-to-day training the examiner issues the certificate, so candidates generalise that the examiner is the decision-maker for everything; in reality complex or borderline cases are referred, and the authority may require specialist reports or impose limitations.

What to do instead

Map the process as a flow: applicant, examination, examiner's finding, referral triggers, specialist assessment, authority decision, certificate issue with or without limitation. For each step write who holds the decision and what the applicant can do if the outcome is adverse, including the review or appeal route.

Mistake 9

Treating an FSTD as interchangeable with the aircraft for every training and testing credit, without checking the device's qualification level, the specific credit the device is approved for, and whether the manoeuvre may be conducted in the device at all.

Candidates see a full-flight simulator and assume total equivalence; the credit depends on the device's qualification basis and on the individual task, and some items must be flown in the aeroplane.

What to do instead

Build a table of FSTD categories and levels against the tasks in the IR(A) syllabus, marking each cell as full credit, partial credit, or no credit. Add a column for the documentary evidence (qualification certificate, approved training course). Learn the difference between a device qualified for training and one qualified for testing, and practise justifying a credit decision in one sentence.

Mistake 10

Ignoring the maintenance-of-currency rules for the FSTD itself, such as the periodic evaluation, the handling of a device that has failed a validation, or the requirement to record and act on device discrepancies before a session is credited.

Candidates study the device from the pilot's seat and never from the training organisation's records; they therefore cannot answer items about whether training conducted after a device's qualification lapsed counts toward the rating.

What to do instead

Write the lifecycle of an FSTD qualification: initial evaluation, recurrent evaluation intervals, change notification, and suspension. For each stage note what the operator must do and what happens to training already conducted. Then write a one-paragraph rule for the pilot: how to confirm before a session that the device may be used for the intended credit.
