Many aircrafts are designed to do many different things. Some carry big loads, travel long distances, and move at a very high velocity,
and some are made to land and take off in a short distance and haul a small pay load. (The figures below display aircrafts designed for both
of these circumstances). Other planes are designed to do everything in between. All of these different circumstances create very different
needs and very different aspects to think about when designing an aircraft.

    One example of an aircraft that is designed to carry a large load, travel at a high rate of speed, and a far distance is the Boeing 747-400.

        This plane has the above needs, so it will need a large amount of power to accelerate to high speeds, have a lot of room and
    still be aerodynamic so it will have to be very large, it will not need a large angle of attack though it will need some, and have a large
    enough planform area to combine with the thrust to produce enough lift to get off the ground. It will also need a long runway and
    land strip to accomodate all this.

    This is an example of a plane designed to carry a small pay load but can take off and land in just a few hundred feet and in some cases even less!!

        This aircraft is a Supercub. It is a very popular Alaskan plane because of it's versatility and ability to get in and out of the remote places
    Alaska has to offer. This plane only has 80 horsepower and can only fit 2 people. This equates to 2 people, their gear, and a moose.
    This aircraft has a low cruise speed, but a quick acceleration and a large Coefficient of Lift. It also has a large angle of attack.
