How to pass the PSTAR: the five traps that catch student pilots

One morning that will not announce itself, your instructor tells you to pull over on the taxiway, unbuckles, and steps out. Every working pilot remembers the sound of that door closing. The airplane climbs like it has been let off a leash — it is suddenly a whole person lighter — the right seat is impossibly empty, and the only voice left on the radio is yours.

Before that door is allowed to close, Transport Canada wants proof on paper. The exam is the PSTAR, and it guards the student pilot permit^[1] — the document that makes a solo legal at all: the moment the door shuts you are pilot-in-command, and nobody flies as pilot-in-command without a permit or licence in their file.^[2]

The PSTAR comes with an unusual deal: every question you can be asked is published in advance. The deal is not as generous as it sounds.

What the PSTAR actually is

The full name is a mouthful — Student Pilot Permit or Private Pilot Licence for Foreign and Military Applicants, Aviation Regulations — which is why everyone calls it the PSTAR. The mechanics are short, and they are all in TC's own study guide, TP 11919E:^[1]

• The bank is public. The guide's front matter says it contains "some 200 questions" — count them and the current seventh edition carries exactly 185, across 14 sections, from collision avoidance to airspace to wake turbulence. Your exam is 50 of those questions, selected from the guide.
• The pass mark is 90%. That is 45 out of 50. You can miss five.
• It is corrected to 100%. After the sitting, every question you missed gets reviewed until the gap is closed — the guide itself says reviewing your weak areas matters "in the interest of flight safety."
• You write it close to home, on a 90-minute clock. Authorized flight training units — usually your own school — administer it, or a Transport Canada office does. Transport Canada's examination rules give you 90 minutes — a generous 1.8 minutes per question. Time pressure is not what fails people on this one.

Read that list and you can see why students walk in loose: an open bank, a short paper, home turf. Then the 90% arrives. A pass mark that high is not asking whether you generally get the idea — it is asking whether you know the rule precisely, and nearly every question carries one option that is almost right. The near-misses are not accidents. They are the curriculum.

Working students through the bank, the same few sections keep drawing blood. Here are five — because the durable fix is not memorizing 185 answers, it is meeting the dozen rules the questions keep circling back to.

Right of way: manoeuvrability wins, not size

The instinct everyone imports from the road is that bigger and faster goes first. The bank hands you that instinct as an option — to the effect of a jet airliner has the right of way over all other aircraft — and it is wrong every time.

The actual rule is CAR 602.19. When two aircraft converge at approximately the same altitude, the one that has the other on its right gives way — yield to the right, like a four-way stop.^[3] That only settles ties between equals. First comes the hierarchy, and the hierarchy runs on manoeuvrability: power-driven aircraft give way to airships, gliders and balloons; airships give way to gliders and balloons; gliders give way to balloons.^[3] The less an aircraft can do about the situation, the more the rules protect it. A balloon can barely steer, so everything yields to it. A helicopter, for all its agility, is power-driven — it ranks with the aeroplanes and gives way to a glider.

Three more pieces finish the section. An aircraft towing a glider (or carrying a slung load) outranks other power-driven aircraft — though still not a balloon.^[3] Head-on, each aircraft alters heading to the right.^[3] Overtaking, the overtaken aircraft has the right of way — you pass by altering to the right, whether climbing, descending or level.^[3] And on approach, the lower aircraft has the right of way — never a licence to cut in front of someone established on final.^[3]

(The regulation even settles two converging balloons: the higher one gives way.^[3])

Light-gun signals: a steady light is a final answer

If your radio dies near a controlled airport, the tower talks to you with a light gun, and the bank tests the signals as pairs — one meaning in flight, a different one on the ground. The five to hold:^[4]

• Steady green — in flight: cleared to land. On the ground: cleared for take-off.
• Flashing green — in flight: return for landing. On the ground: cleared to taxi.
• Steady red — in flight: give way to other aircraft and continue circling. On the ground: stop.
• Flashing red — in flight: airport unsafe, do not land. On the ground: taxi clear of the landing area.
• Flashing white — ground only: return to your starting point on the airport.

The trap lives in the greens. Return for landing sounds so close to cleared to land that the exam can simply offer both and let your optimism choose. Hold the pattern instead: a steady light is a final answer; a flashing light is a redirection. Steady green is the clearance itself; steady red parks you where you are — circling, or stopped. A flashing light wants something to change: come back, taxi, clear the landing area, go back where you started.

MF and ATF: "uncontrolled" does not mean unscripted

The word uncontrolled does a lot of quiet harm. No tower does not mean no procedures — at many uncontrolled aerodromes there is a mandatory frequency (MF), and the regulations spell out the reports you must make on it — arriving, departing, moving through the circuit — plus a listening watch while you are in the area.^[5] Three details do most of the damage:

• The numbers live in the Canada Flight Supplement. The MF itself, and the distance and altitude that define the area, are published in the CFS (or the water-aerodrome supplement) entry for that aerodrome — not in the AIM, and not on a chart legend.^[4]
• A closed ground station does not end the calls. If the flight service station is shut for the night, you keep making every report — addressed to "(aerodrome name) traffic," not to a unit that is not there.^[5]
• Departing, you are not done at circuit height. You monitor the MF until you are beyond the published distance or altitude. "Clear of the circuit" is the near-miss option, and it is wrong.^[5]

Where an aerodrome has no MF and no UNICOM, the default aerodrome traffic frequency (ATF) is 123.2 MHz.^[4] If you train at an uncontrolled field, this is not exam trivia — it is the script for every circuit session between now and your solo.

Wake turbulence: the calm day is the dangerous one

Intuition says turbulence belongs to wind, and that the most dangerous airplane is the huge one with everything hanging out on final. The bank disagrees with both, and the bank is right. Here is one question exactly as published:

Wake turbulence will be greatest when generated by an aeroplane which is

— and the keyed answer is "heavy, clean configuration and slow speed." (TP 11919E, question 7.12 — Transport Canada's question and answer key, reproduced with attribution.)^[1] The near-miss option is heavy in landing configuration — exactly where the hand wants to go, because a jet with everything out looks fiercest. But wake is a by-product of lift: heavy and slow means the wing is working its hardest, and a clean wing sheds tighter, stronger vortices than one with flaps and gear disturbing the flow.^[4]

The rest of the section rewards the same recalibration:

• Still air is the worst case. With no wind to break them up, hazardous vortices can persist for five minutes or more.^[4]
• A light crosswind can be worse than none. Vortices drift with the wind — a light crosswind can hold the upwind vortex parked over your runway, or walk the other one onto the parallel.^[4]
• The wake starts at rotation — the moment the wing starts lifting — and it sinks below and behind the aircraft that made it. Departing behind a large aeroplane, plan to be airborne before its rotation point; landing behind one, stay above its path and touch down beyond its touchdown point.^[4]
• Avoiding all of this is your job, not ATC's. A controller may caution you; the decision, and the separation, belong to the pilot-in-command.^[4]

Clearances and instructions are different sentences

To a student, everything a controller says sounds equally official. The regulation splits it in two, and the bank tests the seam relentlessly.^[6]

An instruction — "hold short," "extend downwind" — you comply with as soon as you receive it, provided the safety of the aircraft is not put at risk. A clearance — "cleared to land," "cleared to the circuit" — is an authorization: it binds you once you accept it. If part of a clearance does not work for you, refuse it and tell ATC your intentions. If you accept one and then find you cannot comply, do the safest thing available and advise ATC as soon as possible — silence is the one wrong answer.^[6]

Two ground-level versions of this show up again and again:

• A taxi authorization to your departure runway lets you cross taxiways along the route, but never a runway — every runway crossing needs its own clearance.^[4]
• A hold-short instruction comes back in your readback with the hold-short words in it, attached to your call sign. Reading back only the runway you are headed for drops the safety-critical half of the sentence.^[4]

And the quiet sentence underneath the whole section: a clearance is based on known traffic only. Accepting one never hands your eyes to the controller — see-and-avoid stays with you, cleared or not.^[6]

How to actually study for it

Nothing above requires spending a dollar to learn. The honest path:

1. Start from the source. TP 11919E is a free download from Transport Canada — the link is in the sources below. That PDF is the exam.
2. Chase every miss to its rule. The guide itself tells you to research the references behind each question rather than rote-learn the answers,^[1] and it is right: a memorized letter fades in weeks, while CAR 602.19 stays learned through the PPL written, the flight test and every converging glider after that. Miss a question, read the CARs section or AIM chapter behind it, then answer again from the rule.
3. Practise to the real bar. Sit full 50-question papers and grade them the way the day will: 45 or better. A comfortable 42 feels close; it is a fail. Calibrate to the number, not the feeling.
4. Interrogate the twins. The bank is full of near-identical pairs — converging-aircraft scenarios, in-flight versus on-ground signal meanings, controlled versus uncontrolled numbers. When two questions look the same, the one word that differs is the lesson.

None of the five areas above is trivia. Converging gliders, a dead radio, a sleeping flight service station, invisible wake, a clearance you cannot make — the paper is a list of afternoons that actually happen to student pilots. The PSTAR is the system asking, before the door shuts: with the right seat empty, are the rules still in the airplane? Study so the answer is yes, and the paper stops being the point.
