Although the odds of experiencing a ditching event are extremely low, pre-flight preparation and knowledge are paramount to survival should it happen.

The following items will enhance your chance of a successful egress.

1.  Pre-flight Preparation

Ensure the pilot-in-command demonstrates the location and use of the emergency exits, life preservers, emergency equipment, life raft, and the proper brace position — before the flight. For extended over-water flights, consider wearing your life preserver. Make sure all baggage and cargo is secured so it does not block access to the emergency exits.

2.  In-flight Preparation

If you are aware that you are about to ditch, do the following:

• Put on your life preserver, but DO NOT INFLATE IT.
• Locate all emergency exits, note where they are in relation to your right or left hand, and visualize how to open them.
• Assume the proper brace position for your seat, as briefed by the crew.
• Follow the instructions given by the pilot-in-command.

3.  Underwater Egress Procedure

• Try to remain calm!
• Take a deep breath prior to being submersed under water.
• OPEN YOUR EYES.
• Orient yourself in relation to your selected emergency exit.
• Get a firm grip on a fixed reference point.
• If you are seated right next to your emergency exit:
  • Wait until the water has filled three quarters of the cabin before you fully open the exit, then open it.
  • Release your safety harness.
  • Pull yourself free from the cabin.
  • Inflate your life preserver after exiting the aircraft.
• If you are NOT seated right next to the emergency exit:
  • Release your safety harness and proceed toward your emergency exit.
  • Wait until the water has filled three quarters of the cabin before you fully open the exit, then open it.
  • Pull yourself free from the cabin.
  • Inflate your life preserver after exiting the aircraft.

Some of the difficulties during underwater egress include lack of oxygen; disorientation; in-rushing water; obscured vision; and floating debris. Don’t panic. You know you can hold your breath, so relax for a moment; open your eyes; find the exit; and egress. These are basic guidelines only, and your best defence is underwater egress training.
