IFR Practice Area Questions Canada: What the INRAT Actually Asks

Most candidates who fail the INRAT do not fail because they do not know IFR procedures. They fail because the exam asks questions in a way that is designed to catch you if you are recalling rules from memory without actually understanding them. There is a difference between knowing that you need an alternate and knowing the exact conditions under which the alternate weather minima apply.

This post runs through the topic areas that produce the most wrong answers, gives you example question styles similar to what you will see, and explains how to think through the tricky ones. Treat it as a study guide for your free INRAT practice test sessions.

The Five Areas That Cause the Most Trouble

Of the 13 subject areas covered on the INRAT (see the full breakdown in INRAT exam categories), five consistently produce the most wrong answers. Here they are, with the specific question styles you need to prepare for.

1. Holding Entries

Holding entry questions are not hard if you know the three entry types. Where candidates trip up is when the question adds time pressure or gives you an inbound course instead of a magnetic bearing to the fix. The INRAT will describe your situation as "you are tracking inbound on the 075 radial and the hold is published on the 270 radial inbound" — and candidates who have only ever practised with a picture in front of them freeze up.

The other trap: the question specifies a left-hand holding pattern. Most candidates have drilled right-hand entries so thoroughly that they apply right-hand logic to a left-hand hold and choose the wrong entry. Read the question again before committing.

2. Comm Failure

Comm failure questions test your knowledge of CARs 602.139 through 602.141 and the associated procedures in the AIM. The question style that trips people up is: "You lose comms in IMC at FL180 on a cleared route. Which altitude do you fly and where do you go?" The answer depends on which altitude is highest among three specific options — and candidates who only remember "fly your last assigned altitude" miss the part about your expected altitude and the MEA.

Key things the INRAT tests on comm failure:

• The three-altitude rule and which altitude takes precedence
• What route to fly when you have and have not received an expected further clearance time
• When to start your approach at the destination
• What to do if you had been cleared to a fix and told to expect a clearance beyond

Wrong-answer trap: candidates choose "last assigned altitude" when the MEA on the next segment is higher. Transport Canada wants you to know you climb to the MEA if it exceeds your last assigned altitude. For the full comm failure procedure including the AVEF sequence and approach timing rules, see the comm failure procedures guide.

3. Alternate Requirements and Minima

Two separate concepts get confused here. The first is when an alternate is required at all — the 1-2-3 rule. The second is what weather the alternate must have to be usable. These are different numbers and the INRAT exploits that confusion deliberately.

Alternate minima in Canada are set per approach type at the alternate. For a precision approach at the alternate, you need ceiling and visibility above a specific threshold. For a non-precision approach, the numbers are different. The INRAT will give you a scenario where the destination is legal but the alternate weather is right on the line, and ask whether the alternate is acceptable.

The trap on alternate questions: memorizing "you need an alternate if the weather is below X" without knowing the specific alternate minima. Both pieces matter and the INRAT tests both.

4. Instrument Approaches — Minima and Segments

Approach questions come in several styles. Some ask about which minima apply to a specific aircraft category. Some ask about step-down fixes and whether you can descend. Others test MDA versus DA — when you must go missed, and what triggers the missed approach.

The MDA versus DA distinction is a common failure point. For a non-precision approach, you reach the MDA and hold it until you have visual reference or reach the MAP. For a precision approach, you reach the DA and you must immediately go missed if you do not have the required visual reference — you do not hold the DA and wait. Candidates who blur this distinction get a predictable question type wrong.

INRAT also tests straight-in versus circling minima. A straight-in is only authorized if the final approach course is within a certain alignment of the runway. If the question involves an approach where that alignment is not met, the straight-in box on the plate does not apply and you use circling minima instead.

5. Meteorology — SIGMET, PIREP, and Icing

Met questions on the INRAT are not about reading a TAF. They are about understanding the operational meaning of a SIGMET, interpreting icing intensity levels, and applying the rules about flight into known icing conditions. The INRAT regularly asks about the validity period and coverage area of a SIGMET, and candidates who have only studied TAF/METAR format are caught off guard.

Icing questions test intensity definitions (trace, light, moderate, severe) and what each means operationally. Severe icing means the de-icing system is overwhelmed — immediate action required. The question will describe an icing PIREP and ask what a following aircraft should do or what the icing intensity means. Candidates who treat all icing as the same fail this type consistently. For a complete breakdown of icing types, SIGMET rules, and the Canadian regulatory requirements, read the aircraft icing guide for the INRAT.

How to Think Through Tricky INRAT Questions

The INRAT is a multiple choice exam, but the wrong answers are not random. Transport Canada writes distractors that represent the most common misconceptions. If you recognize the misconception being tested, you can usually eliminate two options immediately.

Here is the approach that works for confusing questions:

1. Identify what regulation or procedure the question is actually testing. Do not try to reason from first principles on something that has a specific rule. If it is an alternate minima question, the answer is in the CARs, not your logic.
2. Watch for "except" and "unless" in the question stem. The INRAT uses these to flip a straightforward rule into its exception, and candidates who are reading fast miss them.
3. On holding and approach questions, draw a small picture. Even a rough sketch of the radial, your heading, and the pattern orientation takes 20 seconds and eliminates most confusion.
4. On met questions, note the units. Visibility in statute miles versus metres matters. Ceiling in feet AGL versus MSL matters. The wrong answer is usually plausible if you misread the unit.
5. If two answers look identical except for one number, that number is the regulation. Go back to your source material before the exam so you know which number is correct.

Common Wrong-Answer Traps by Topic

These are the patterns that show up repeatedly in practice test results:

Holding entries: Applying right-hand entry logic to a left-hand pattern. Confusing the inbound course with the bearing to the fix. Choosing the entry based on the aircraft's current heading rather than the course to the fix.

Comm failure: Stopping at "last assigned altitude" without checking if the MEA is higher. Forgetting that the expected altitude rule applies. Not knowing the timing rules for when to begin the approach.

Alternates: Using destination minima when the question asks about alternate minima. Confusing the "is an alternate required" rule with the "what weather must the alternate have" rule. Forgetting that some aerodromes cannot be filed as an alternate at all.

Approaches: Confusing MDA with DA and the different miss-point rules. Not checking alignment before applying straight-in minima. Applying the wrong aircraft category.

Met: Treating moderate and severe icing as equivalent. Misreading SIGMET validity periods. Confusing icing intensity definitions.

How to Structure Your Study Around These Areas

Most candidates who pass on the first attempt spend at least one dedicated session on each of these five areas — not reading the CARs front to back, but working through practice questions and then looking up the regulation for every wrong answer. The regulation lookup is what makes it stick. The TP 691E is the right reference to return to when a question exposes a gap — it covers all 15 exam categories and is free from Transport Canada.

For holding entries and approach questions specifically, the knowledge only becomes reliable once you have done enough repetitions that you stop having to reconstruct the rule each time. That takes practice questions, not more reading. Start with the free INRAT practice test to get a baseline on where you currently stand, then focus your remaining time on the areas where you are dropping marks.

The INRAT is a 70% pass mark on 100 questions. That means you can afford 30 wrong answers — but you are not going to know which 30 those are in advance. The candidates who fail are usually 3 to 5 questions short and those questions are concentrated in one or two topic areas they did not study specifically enough. Do not let it be holding entries or alternates. Those are learnable in an afternoon if you approach them correctly.
