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?

Answer: Protection, Location, Acquisition, Navigation
Rationale: These priorities structure post-evacuation actions. Protection
prevents exposure injuries, location improves rescue chances, acquisition
secures resources like water, and navigation manages movement if
relocation is necessary.
What is the Least Risk Bomb Location?
Answer: Area that would cause least damage to the aircraft
Rationale: LRBL placement is engineered to direct blast effects away from
critical control runs and pressurized structures. Using the LRBL reduces the
probability of catastrophic structural failure.
Can used refuse bags be left in the washroom?
Answer: Yes 2.12.3.2
Rationale: Temporary, secured stowage mitigates contamination and
obstruction risks in galleys and aisles when service volume peaks.
Procedures ensure disposal does not create fire, odor, or access issues.
Which level of interference would be associated with someone smoking on
board?
Answer: Level 1
Rationale: While hazardous, especially near lavatory detectors and oxygen,
isolated smoking typically represents noncompliance without violence,
fitting Level 1 with progressive steps before escalation.
If slides do not touch the ground or are blown upwards during an
emergency landing, are they still usable?
Answer: No, you should redirect the passengers
Rationale: A slide thatʼs floating or too steep can cause severe injuries or
pileups. Redirecting preserves evacuation flow to usable exits and prevents
creating a new hazard.
What should Cabin Crew do before initiating a rapid deplanement?
Answer: Advise PIC (if possible); ensure bridge/stairs attached; evacuate if
not attached
Rationale: Coordinating with the PIC prevents opening doors to a void and
ensures safe egress pathways. In an escalating hazard, exception protocols
permit immediate evacuation without equipment.
