A remote pilot is about to launch for a routine inspection flight when they receive news of a stressful personal situation. They feel distracted and their mind is not on the mission. Under IMSAFE, what should they do?

Why →The S in IMSAFE stands for Stress, defined as any psychological pressure that affects judgment or attention. A pilot who is distracted by personal news and self-reports that their mind is not on the mission has already identified an IMSAFE failure. The FAA recognizes stress as a physiological hazard equivalent to illness or fatigue. Postponing the flight is the correct response. A routine inspection can be rescheduled. An accident cannot be undone.

The trap →Launching as planned treats emotional fitness as irrelevant to professional aviation operations. The FAA explicitly includes it. Doing a preflight inspection first is a delay tactic that will not resolve the distraction. A preflight inspection does not change the pilot's mental state.

Field note →IMSAFE is most valuable when applied honestly. The items most commonly skipped or rationalized are Stress and Fatigue, because pilots feel they should be able to push through them. That rationalization is exactly the hazard the checklist is designed to catch.
