Failure to brief passengers

An unbriefed passenger is the one variable in the cockpit you chose not to manage. In a calm cabin that costs nothing; in an emergency it can cost you the exit, the controls, or the seconds you didn't have.

What's required versus what's wise

The honest regulatory picture, as with the rest of this task: the mandate is thin. The only Part 91 requirement that touches passenger briefing is §91.107(a) — before takeoff the PIC must ensure each person aboard is notified to fasten their safety belt and shoulder harness and is briefed on how to use it. That's the floor, and it's about belts, not emergencies.

There is no comprehensive Part 91 emergency-briefing mandate for small general aviation — no rule requiring you to cover exits, the fire extinguisher, or what to do if you're incapacitated. The fuller briefing is best practice, not regulation. DPEs probe this line deliberately: they want to see that you know which side of it you're standing on, and that you choose to go well beyond the legal minimum because it's good airmanship, not because a reg forces you.

The passenger as hazard or resource

Skip the briefing and a passenger becomes a hazard in the emergency: someone who can't find the door release while you're flying a forced landing, who blocks an exit, who grabs the yoke in a panic, or who simply freezes and becomes one more thing you're managing with your hands full.

Brief them well and the same person becomes a resource — a second set of eyes for traffic, a hand to hold a chart or read a checklist item, someone who knows to stay quiet and braced when you say so. The briefing is how you convert the unknown in the right seat into either a help or, at worst, a non-problem.

The SAFETY brief

A clean, memorable framework for the pre-takeoff brief is the SAFETY check, as the FAA lays it out in its Passenger SAFETY Briefing:

• S — Seat belts: how to fasten and, critically, release them.
• A — Air vents: how to work the cabin air and environmental controls.
• F — Fire extinguisher: where it is and how to use it (and any other emergency equipment aboard).
• E — Exits: how the doors open — have them put a hand on the latch — and areas to avoid, like the propeller.
• T — Traffic: help look for other aircraft, and keep quiet during critical phases.
• Y — Your questions: invite them — a passenger who asks now won't be guessing later.

One caution: brief for confidence, not fear. Calm and specific — "here's the belt, here's the door, if I get busy just stay quiet" — leaves a passenger reassured and useful. An alarming recitation of everything that could go wrong leaves them rigid. The goal is a prepared passenger, not a frightened one.
