As you probably know, there are many types of transportation, and the fastest type of transportation is air travel. Not only is it faster than land and sea travel, but it is also proven to be much safer. In this report, we will be focusing on airplanes.
Airplanes have many purposes. They’re not just for
taking passengers to their destination; they are also used for other
reasons such as delivering mail or fighting wars. Did you know that
some people use planes for doing tricks such as loop the loops or
plunging down at a vertical drop and swooping up right before they hit
the ground? These people perform their tricks at shows and ride special
planes called Acrobats. Other planes are used for fighting wars and
battles, like Jump Jets. Jump Jets are planes that need very little
runway and can land vertically. Another kind of
army jet is an Interceptor. An Interceptor is a plane that finds enemy
aircraft and stops them from bombing targets.
There are many different kinds of planes and some of them are
really odd like the glider. The glider is a
plane that has no motors. Instead, it is towed by
another plane, then when let go, it relies on currents of
warm air (thermals). Another weird kind of airplane is a commuter
airliner. Commuter airliners are smaller than regular passenger
and travel shorter distances. Commuter airliners typically have engines
with six propellers that push the plane forward. This is why they’re
called pusher engines. Commuter airliners also have radar in their nose
cones, so they can detect weather that’s miles away from them. There
are also planes that land on water instead of land. These planes are
called seaplanes. Instead of wheels, they have floats so they can float
on the water.
There are three main flying instruments on a plane, including:
1. The Air Speed Indicator – this tells the pilot how fast the aircraft is going. It’s kind of like a speedometer on a car except in knots instead of miles per hour or kilometers per hour.
2. The Horizontal Situation Indicator - this picks up navigation beams from its destination and indicates the distance and time it will take to reach the destination.
3. The Attitude Detector – this tells the pilot the difference between how straight the wings are compared to the horizon, so the pilot can match them up.
are also other instruments such as the compass (it tells the direction
the plane is going) and the altimeter (it tells how high the plane is
above the ground).
Air travel is getting more advanced everyday. They think that someday people will be able to travel in a plane outside the atmosphere. Wouldn’t that be great?
