FedEx pilot Bryan Webster was waiting for his Cessna Caravan to be loaded with cargo and spending the time browsing through aviation periodicals.
In article about ditching was of interest because his job involved single-engine operations over bays, large lakes, and shorelines. He recognized that even when within gliding distance of land, there are times when an engine failure could result in ditching because a forced landing on hostile terrain might be the less-desirable alternative.
Webster was startled to read facts taken from a government study stating that more than two-thirds of those who perish are not injured from the ditching itself but from failure to extricate themselves from the aircraft and subsequent drowning. (The remaining pilots and passengers die from impact injuries, nonfatal injuries that result in drowning, and exposure.) Of those who survive a ditching, only 8 percent manage to escape the aircraft without difficulty.
Furthermore, Webster learned, 90 percent of those who drown are involved in ditchings during which the aircraft becomes inverted in the water. The probability of survival is many times greater when the aircraft comes to rest right side up.
Based on this data, the study concluded that the fatality rate could be significantly reduced for landplane and seaplane pilots who opt to take underwater egress training. But when Webster looked into the availability of such training, he found that the only facility in his home country of Canada was on the other side of the continent in Nova Scotia, catered primarily to military and airline customers, and was cost-prohibitive for most general aviation pilots. "There are several facilities in the States," he adds, "but these also are quite expensive."
Unknown to Webster at the time, this was to become a turning point in his life. After considerable research, he decided to develop a curriculum, design necessary equipment, and form his own company, Aviation Egress Systems in Victoria, British Columbia. His one-day course is specifically tailored for general aviation pilots and has become so popular since its inception almost two years ago that Webster ultimately resigned from his position with FedEx. He now devotes all of his energy to teaching pilots what they need to know about evacuating an aircraft in the water.
Each class is limited to six students and is held at the large (24 by 37 feet), heated, indoor pool at the Iris Garden Country Manor, a delightful bed-and-breakfast in a forested suburb of Victoria.
My motivation for taking the course stemmed from an accident I had in Alaska in 1972. Following an engine failure, the Piper Super Cub that I had been flying wound up inverted in the water. My first instinct was to attempt pounding out a window, but water resistance prevented me from developing sufficient force. Panic began to set in, and I felt pain developing in my chest as I resisted the natural and almost overwhelming urge to inhale. After conceding that this might be the end of my life, the thought finally occurred to open the door. I did and found myself standing in 5 feet of water. The panic caused by suddenly discovering myself inverted and underwater in an airplane had numbed my mind and delayed logical action almost until it was too late. I realize now that the ordeal would have been far less traumatic if I'd had underwater egress training prior to this accident.
Webster's course begins with an enlightening two-hour discussion about ditching concepts, safety tips and equipment, and escape procedures. This is when we were taught to open the cabin door prior to ditching so that the structural distortion of the fuselage that can occur on impact does not jam the door and prevent escape.
Webster also teaches a simple procedure to prevent the door from closing during a water landing. Prior to landing and with the door open (ajar), turn the door handle as if you were going to lock the door normally. In most aircraft, the locking mechanism extends aft and strikes the outside of the doorframe, thus preventing the dynamic forces that can occur during a water landing from forcing the door closed and trapping you inside.
Webster explained the need to remove and stow headsets and other loose objects before ditching because they can become projectiles upon impact with the water. He also demonstrated how headset wires connected to their jacks could impede egress.
Perhaps the most critical lesson is to resist the temptation to hurriedly release your seat belt and shoulder harness even if the aircraft submerges and especially if it is inverted. Doing so can cause you to begin floating in the cabin and perhaps into the rear seat or tail cone where you could become trapped. Disorientation at such a time is likely and the mere act of locating the door and/or its handle can be difficult if not impossible. Many have drowned because they became turned around and tried desperately to turn the door handle in the wrong direction and wound up breaking it off instead, forever sealing that exit and diminishing hope of survival.
Instead, the pilot needs to maintain his orientation and his normal, relative position with respect to the door or emer.gency exit. He should resist unbuckling himself until after locating the door, opening the exit, and creating an escape path.
The next two to four hours of the course (depending on how much experience you want or need) are spent in and around the pool with occasional briefings in the sauna and refreshment breaks.
The first exercise before being introduced to the dunker involves jumping into the pool and attempting to unpack and don a life vest while trying to stay afloat — more difficult than you might imagine. The exercise teaches that life jackets should be worn, not stored. And never inflate a jacket until you are outside the aircraft. Their exercises teach how to hoist oneself into a raft and to assist "injured" passengers to do the same. We also experienced how to remain noticeably warmer in the water by huddling close to other "survivors."
Students also are given an opportunity to practice opening the side window of a Cessna 172 and experience what it is like to escape through such a window while underwater.
Next comes the dunker, which some refer to as the Intimidator or Bryan's Torture Chamber. The submersible cockpit simulator is a single-place, perforated cylinder that on the inside resembles a cockpit, complete with safety belt and shoulder harness, a mock instrument panel, and basic controls. A small placard on the panel is engraved with a tongue-in-cheek Canadian registration for the "aircraft": CG-AEU (CG.is the national designa.tion for Canada; AEU is the suffix of the registration and in this case stands for aviation egress underwater).
Webster says that the dunker reminds some of bungee jumping; it doesn't look intimidating until the rope is tied around their ankles.
My pulse rate increased as I sat in the dunker at the top of the ramp, looking down toward the water at a 45-degree angle and waiting to be released.
The dunker hits the surface at only 20 mph but at a much steeper angle than would occur during an actual ditching, which helps to simulate the real thing. You barely have time to take one last breath before being hit by a wall of water, simulating an "exploded" windshield, which often occurs during an actual ditching.
During this first exercise the dunker remains upright, and you have little difficulty getting out as long as you remain calm and remember the golden rule of ditching: Do not unbuckle yourself until you've used familiar reference points in the cockpit to locate the door, find the handle, and create an escape path.
Webster and another scuba-equipped assistant (a professional diver) are in the water during all dunking operations to assist anyone who might become disoriented and have difficulty getting out. Webster tells of one pilot who escaped in good time but immediately dove for the bottom of the pool and had to be pulled up. (About one out of 20 students initially needs assistance of some sort.)
In the event that something occurs to prevent the dunker's door from opening conventionally (this has never happened), Webster or the other diver can pull a rod that allows the door to fall away and enable rapid egress. If the seat belt or shoulder harness should jam (this has not happened either), the student can be quickly disconnected from the dunker (while still wearing the belt and harness) and hauled to the surface of the pool. Webster claims that no student has ever been injured or endangered.
During the second dunking, Webster and his assistant flip the "aircraft" upside down, and this is much more disconcerting and challenging. But confusion is avoided as long as you obey the aforementioned golden rule.
I used to think that it would be easy to distinguish up from down by exhaling and observing the direction of bubbles. I discovered that this might not be possible during a ditching because there is a chaotic storm of bubbles amid the churning water. Also, the bubbles might lead you to a dead-end trap in the tail, which often contains a large air pocket that keeps the aircraft in a tail-high attitude. At night or in murky water, you might not see bubbles at all.
After hitting the water during the third attempt, Webster and his associate do their best to disorient the student by rolling and pitching the dunker every which way until finally allowing it to come to rest in some unusual and inverted attitude.
For those who want the ultimate E-ticket ride, you can volunteer to slide down the ramp and hit the water while inverted. (I didn't.)
Next comes the two-place dunker. Its cockpit is the size of a Piper Pacer and is used to teach a pilot how to save an injured passenger unable to extricate himself. After getting out of the aircraft, the pilot is taught to initially ignore the passenger and head for the surface for a fresh supply of air. He then goes back underwater and swims to the door through which he will assist his passenger — not particularly easy when the limp body is hanging upside down. I found it difficult just to find and unbuckle the seat belt. (The student playing the part of the injured passenger is breathing through a regulator and an air tank installed in the dunker because the rescue sequence can take up to a minute.)
The final exercise involves riding either the single- or two-place dunker into the water while wearing a pair of goggles with black lenses to simulate ditching at night. After Webster and his friend have finished rolling and pitching the dunker, you find yourself in a world of black confusion. But strict adherence to the golden rule quickly restores confidence and allows for an expeditious escape.
All of the exercises are challenging even though they are conducted in a warm, indoor pool during daylight hours. The experience is thoroughly educational and filled with camaraderie.
I discussed with fellow student Robyn Astaire how much more difficult it would be to survive a "water landing" in cold, rough water, especially at night. We learned enough to know that we didn't relish the thought and vowed to modify our flight-planning philosophy with respect to operating over and near bodies of water.
When your life is in peril, there is a tendency to panic, especially when you are untrained for the emergency and unprepared to survive. There is little doubt that Webster's course will help to replace panic with confidence should you wind up inverted in the water. Considering the increasing popularity of Webster's course, one might say that he is making quite a splash.
