The presentation on aviation and learning about the components
of flight with David Werntz was an eye opening experience in regards to the
practicality of flight. As I read about flight in “Into the Blue,” I could feel
a sense of romanticism, especially during the era of the Wright Brothers and
Amelia Earhart. It seemed as if it was a feat capable only achieved by the
select few. This thought was further solidified by space travel, as only a few
astronauts were selected to venture into space. However, as David Werntz
reiterated today, flying, at least in the Earth’s atmosphere, is within our
abilities: it is something that could be done with just a little bit of
practice, dedication, and money.
Perhaps the most interesting part of the technical aspect of
flight was the aileron. Although it is small in its size, it does so much in
terms of contribution to the flight. The analogy in class was by putting the
hand out of a moving car. If we angle our hand flat, parallel to the car, there
is no lift nor is there drag. However, if we lift our hand perpendicular to the
car, its all drag and no lift because the wind is directly toppling on to the
surface of the hand. To find a compromise, it is important to find an angle
(17ยบ) at which there is the greatest amount of lift, and a minimal amount of
drag. This is applied to the aileron: I’m amazed as how the small piece of
metal is capable creating such a difference in the functions of flight. Furthermore,
it also surprised me that David was able to land anywhere he wanted. As seen in
movies, it always took a lot of preplanning with the flight tower to coordinate
a safe descent; however, he made it seem very simple as to where he wanted to
go and how he wanted to land.
Its interesting to note that one generally associates going
up on a plane with losing all power since you have no control. However, Werntz
proves that he actually feels more in power and more carefree. He reads his
maps, takes naps, and only has to focus when he’s landing. The lack of traffic
gives him a sense of limitless that is taken away when he’s driving a car on
moving on land.
