Which option correctly expands PACE?

• A. P: Panic; A: Alert; C: Check; E: Evacuate
• B. P: Probe; A: Alert; C: Challenge; E: Emergency
• C. P: Prepare; A: Alert; C: Challenge; E: Emergency
• D. P: Probe; A: Alarm; C: Challenge; E: Evacuate

Answer: (B)

PACE is a staged response used to manage uncertain or unsafe situations in an aviation context. Start with probing to gather facts and clarify what’s happening without jumping to conclusions. This helps you determine the seriousness of the situation and avoid overreaction. Next, you alert the right people—notify the crew or control as needed so everyone who should know is aware and can prepare to respond. If unsafe actions or objections persist, you challenge them—assertively and professionally—to stop the behavior and maintain safety. If the situation still cannot be resolved or escalates, you treat it as an emergency and trigger the formal procedures to bring in the appropriate assistance or authority. The correct expansion is Probe; Alert; Challenge; Emergency. This sequence reflects a controlled, escalating response: first understand, then inform others, then push back on unsafe actions, and finally escalate to the emergency protocol. Other options use terms that don’t fit the standardized sequence (for example, reacting with panic or using a general alarm or evacuation label instead of the formal emergency trigger). Evacuation can be a consequence of an emergency, but the last step in this mnemonic is to initiate the emergency procedures, not to specify a specific action like evacuation.
