A Seatbelt’s Job Goes Beyond The Crash
Think your seatbelt only helps you when the metal hits the dirt? Nope. The magic of seatbelts goes far beyond the prevention of injuries and fatalities during actual impacts. Seatbelts also help the plane fly better and move more safely during maneuvers, sometimes preventing that impact from even occurring.
The first way seatbelts do this is by helping to moderate the weight and balance of the aircraft. Limiting the numbers of jumpers on board to the number of seatbelts limits the risk of overloading the plane, which we all know is a bad scene (slower acceleration, sloth-like climb, stall danger due to higher stall speed, and the like). It also keeps the wiggly weight of the passengers pinned in place, helping the pilot maintain control.
Take an example. One day, a Cessna 205 aircraft ran out of fuel just after takeoff from Celina, Ohio. (Everyone on board--the pilot and five parachutists--perished in the incident, so witness reports and NTSB investigation reports are all we have to explain what happened.) DiverDriver.com explains that, of the witnesses that reported hearing the airplane during climbout, each “described smooth engine noise, brief ‘sputtering,’ and then a total loss of engine power. The airplane descended straight ahead at the same pitch attitude, then the nose dropped, a parachutist exited, and the airplane entered a spiraling descent.” That first jumper left from the student position--as the door was under the wing and not in the rear like the Cessna U206. His exit abruptly shifted the weight aft, rendering the aircraft uncontrollable. Two more jumpers attempted to exit. The all three jumpers who exited the aircraft were unable to deploy parachutes. Everyone left in the aircraft perished in the violent resulting crash.
Another sacred duty of the seat belt: to help the pilot maintain precious, tenuous drabs of control during violent maneuvers in the lower end of the altitude spectrum. Belts hold skydivers in place during the top-gun shit that pilots have to pull sometimes in order to avoid mid-air-collisions, stopping meat from rattling around the cabin and coming down unbalanced.
Note: As skydivers. we’re at pretty serious risk for these, because this kind of incident is statistically most likely to happen in the crowded, lackadaisically-controlled airspace around the small airports we tend to frequent.
When two planes go head-to-head, pilots are taught to pull power and dive to the right--which slams un-belted jumpers right up into the ceiling. The landing is a mystery, but if too many of them land too far aft, the airplane will be unbalanced, stall and spin. Whee. Ugh.
“Sure,” you say, “But that shit hardly ever happens.”
Au contraire.
In the next installment, we’ll take a look at the long list of recent incidents you haven’t even heard about--and meditate on the totally-coulda-been-you aspect of the thing.
