When taking passengers, what should I do to prepare them?
I go through the SAFETY checklist with all my passengers.  The FAA recommends this as well.


Seat Belts - This is where they are and how to use them.
Air Vents - Here are the air vents and how to use them
Fire - In case of a fire here is the location of the fire extinguisher and this is how you use it. PASS method.
Exits, Emergencies and Equipment - Here are the exits on the airplane and here is how to open the door.  Know that you are in good hands and that I have been well trained to land safely under most situations.  If for some reason an emergency occurs in flight follow my directions.  If we need to land off the airport, I will ask you to pop open the door just before landing to ensure we can exit the airplane safely.  Here is any safety equipment that you may want to use on this flight. i.e. supplemental oxygen.
Traffic and talking - Please point out an traffic that you see and I will do the same.  Please no talking while I am on the radio.  Once we start taxiing to the runway please remain quiet til we are far enough away from the airport.  I will let you know when it is safe to talk again.  When we come in to land, I will ask that you remain quiet, unless an emergency situation occurs, till after the landing is complete and we are taxiing back to parking.
Your questions - Do you have any questions?  Alright, lets go have some fun!
