Sign In. Research shows flying is approximately 19 times safer than driving. There are over million registered passenger vehicles in the United States, so the risk of a collision when driving is naturally greater than that of flying in an airplane. Airplanes can still fail, however. Rather, they feature multiple engines to safeguard against failure. The Airbus A and Boeing , for example, are powered by four jet engines.
Some commercial airplanes, in fact, have six engines. The mere sight of a trained hawk or falcon can repel other avian species from the area.

Rescue boats float next to U. Airways Flight floating in the water after it Capt. Miraculously nobody was seriously injured. Pilots Bob Pearson and Maurice Quintal were hailed heroes after they glided their Boeing safely from 41, to land on a Manitoba race car track in Gimli, Manitoba.
The airplane was dubbed the Gimli Glider from then on. Now That's Interesting. Cite This! The pilot will also deploy the landing gear early to create drag. Now, the goal is to put the aircraft down at the lowest possible speed to help with the braking and bring the plane to a complete stop. When it comes to gliding ratios, all aircraft are different, meaning they will lose altitude at a different rate.
For example, say the plane has a lift to drag ratio of it means that for every ten miles of flight, it loses one mile of altitude. If the aircraft was at the height of 36, feet seven miles , the plane could fly for 70 miles before hitting the ground.
A scenario like this could happen if engine power was lost due to the two causes that we did not mention yet. These are flying through volcanic ash or running out of fuel. Back to the bird strike incident, we talked about most engine failures happening at a much lower elevation when taking off and landing.
Miraculously, all people aboard were rescued by nearby boats. This is proof to passengers that if both engines fail, there is an excellent chance that even if the plane cannot make it to an airport, it could still all end well! So, if this plane is 36, feet seven miles high, it could fly for 70 miles before reaching ground level. Different aircraft have different glide ratios.
A Boeing had a glide ratio of , and a Boeing has a ratio of Generally, it is extremely rare for all engines to fail while in the air. However, modern aircraft have helpful systems in place to help aviators cover every possibility. Captain Chris , a senior Airbus A training captain recently spoke about the processes on the aircraft that he flies.
Most airliners can glide for about miles. A wind-milling start uses forward airspeed to spin the large front fan-blades spin at a rotational speed sufficient for an engine re-light. However, the speed to achieve this reduces the glide range.
