Air Canada SEP Q&A — Randomized with Rationales
Why and when would the PIC elect to dump fuel?
Answer: To reduce aircraft weight prior to landing
Rationale: Transport-category aircraft often depart near maximum takeoff
weight, which can exceed maximum landing weight. In an early return or
abnormal situation, fuel jettison reduces structural loads on landing,
improves stopping performance, and keeps touchdown within design limits,
thereby minimizing risk to airframe and occupants.
T or F The plane is able to depart with ice or debris on the wings of the
plane if it is not severe.
Answer: False The plane should NEVER depart with any ice or debris on
its wings.
Rationale: Even small surface contamination can severely disrupt boundary
layer airflow and lift, increasing stall speed and degrading controllability.
Clean-wing policies stem from accident history and certification data
demonstrating that “minorˮ contamination can be catastrophic in critical
phases.

What is the duration of a portable oxygen bottle on low?
Answer: 128 minutes
Rationale: Portable oxygen duration is a function of cylinder volume and
flow rate. The low-flow setting is intended for less acute cases and
conserves supply, allowing crew to remain mobile and render assistance
over extended periods during smoke, fumes, or medical events.
What are the three types of hijackers?
Answer: Goal-oriented criminals (incl. refugees), terrorists, and mentally
disturbed
Rationale: Categorization informs risk assessment and tactics. Motivations
and predictability differ across these types, guiding de-escalation, delay,
coordination with IFSO, and decisions to prioritize containment versus
immediate intervention.
In a rejected take off where the plane veers off the runway, what should
cabin crew do?
Answer: Begin shouted commands
Rationale: Rapid, authoritative commands synchronize passenger behavior
under high stress to minimize injury and prepare for a possible evacuation.
Early control of the cabin reduces panic, prevents premature standing, and
improves readiness if an evacuation is ordered.
What should you do during rapid depressurization?
Answer: Put on drop-down mask as soon as they drop; sit and fasten
seatbelt; sit on floor and hold structure if necessary.
Rationale: Hypoxia can incapacitate within seconds at altitude; oxygen first
is critical. Securing oneself prevents secondary injuries from abrupt aircraft
maneuvers during emergency descent while the flight crew regains a safe
altitude.
T or F Cabin Crew must verbally confirm with passengers seated at
unmanned exits that they understand the briefing and are capable and
willing to take on this responsibility.
Answer: True 2.8.3.1
Rationale: Verbal confirmation ensures able-bodied persons are both
competent and consenting to operate exits. This reduces delay, misuse, or

abandonment of critical exits during time-pressured evacuations.
What is the Silent Review?
Answer: Operation and location of exit(s); location of emergency
equipment; disabled passengers; able-bodied passengers; bracing
position; commands
Rationale: A structured mental rehearsal during TTL primes attention and
recall, shortening reaction time in rare but high-consequence events. It
aligns actions with seat-specific duties and nearby resources.
What are the pre-flight checks for the Interphone handsets?
Answer: Functional
Rationale: Intra-crew communication underpins coordination for routine and
emergency procedures. A malfunctioning interphone can delay critical
messages, including fire, medical, or security alerts.
If there is excessive smoke in the cabin, what do you do?
Answer: Don an oxygen mask, get passengers to bend over and breathe
through their shirts, avoid opening the flight deck door
Rationale: Protecting airway and vision preserves crew functionality to lead
the response. Keeping passengers below the smoke layer improves
survivability, and limiting flight deck door cycles prevents smoke infiltration
into the cockpit where aircraft control must be maintained.
What are the two types of emergencies on the PELC?
Answer: Prepared and unprepared
Rationale: Prepared scenarios allow for full briefing and cabin preparation;
unprepared events demand immediate, simplified actions. Distinguishing
the two determines the applicable steps and announcements to maximize
safety amid time constraints.
What would you yell if someone tries to access the flight deck and the door
is open?
Answer: Door! Door! Door!
Rationale: A short, unambiguous call-to-action focuses crew attention on
the single highest-priority security task: securing the cockpit barrier.
Brevity cuts through noise and panic.
What are the four required elements of survival?
