DUNK YOU WITH “BRY THE DUNKER GUY”

Spring is on the way and soon busy aviators will be everywhere
April is near, and with that a reminder of former day’s enjoying Canada’s outdoors and all the wonderful airborne hours only flight could possibly provide.
The freedom of flying and our ability to reach favorite destinations from take off at a local airport or your own dock in the front yard is immeasurable.
Once the snow has disappeared and ice melted airports everywhere will be a buzz with annual maintenance requirements and the usual wheels to float change over.
Then once the tools are put away and hangar floors swept clean you realize flying has begun and you must now justify the cost per hour to cover these expenses by squeezing precious minutes out of an all too short season.
Soon you will find yourself off for adventure with your craft high above all different terrain including flat land, mountains and often open water.
This is a time to give thought to emergencies which you the pilot could encounter en-route and how to handle anything from an engine failures to a ditching.
First question, do you have on board everything required for your particular trip such as life vests and the knowledge of how to inflate such a devise under the stress of real life drama?
Secondly do you understand the effect of landing on water with fixed gear or possibly floats with amphibious gear in the down and locked position.
To better understand, think of water as the ultimate distance stopping device followed by
an impact which can only be described as extremely violent, all while enclosed in a box soon to be held underwater.
For a conventional wheeled aircraft such as a Cessna 172 most ditchings result in a sudden stop of roughly the aircraft’s length no matter the speed, followed by an inversion.
Similar reaction for the tail daggers out there due to the forward exposed gear legs making contact with the water surface first, although there is a higher certainty of one quick flop onto the aircraft’s back.
As for Amphibious aircraft that all too often land upon water with the gear down, it depends mostly on the manufacturers design and front gear leg location regarding the outcome, although high percentages stop and flop.
Then there are the retractable who loose power after take off out over water and pray the gear is up before landing on the liquid surface with the wheels safely stored in the wells.
The reasons aircraft enter water when least expected is not important, it is how the occupants react in the first few second which is.
Water temperature due to cold shock and impact velocity are by far the largest variables to consider which often cause the panic and disorientation leading to fatalities.
Knowing what to expect from Egress training previously will make all the difference should this ever happen to you, which is why the Military has made this course mandatory in flight crews for many decades.

Bryan Webster is a 11,000 hour plus pilot actively flying a Beaver on the BC coast today when not Egress Training.
In 1977 he was a passenger involved in a water crash while the pilot attempted to avoid power lines draped over the Fraser River east of Vancouver, BC.
