How does a jet

engine work?
First, we need to travel back to middle
school science class. Remember Sir
Isaac Newton’s third law of
motion? For every action
there is an equal and
opposite reaction.
That’s the main principle
behind a jet engine.
Imagine releasing an inflated
balloon; the escaping air blows out
the bottom and propels the balloon in
the opposite direction. That’s essentially
what happens in a basic jet engine. Air is
sucked into the front of the engine by a fan.
This air is then compressed, sprayed with
fuel, and lit with an electric spark to create
a burning gas. The gas expands and then
blasts out the back of the engine. As this
gas shoots backward, the engine and the
aircraft are thrust forward.
Do older planes get to retire?

You may have noticed that the tip of a plane’s
wing doesn’t end in a point; it either curves up or
has a plate on the end that extends upward and
downward. These projections are called wingtip devices, or winglets. They come in different
styles, but they all serve the same purpose — to
reduce turbulence and save fuel.
During flight, high-pressure air below the wing
curls around the wingtip and meets the lowpressure air above the wing, creating a vortex-like
airflow. These vortices create drag on the aircraft.
The winglets break up the vortices and reduce
drag. This makes for a smoother ride and also
helps cut down on fuel costs.
While there are several different types of
wingtip devices, you’ll typically see two varieties
on US Airways planes. Blended winglets (often
found on Boeings) curve upward at the end of
the wing. Wingtip fences (often found on Airbus
aircraft) are plates that extend above and below
the wingtip.
US Airways’ planning
departments decide if
and when a plane should be
retired from flying. They consider the plane’s age, operating
costs, maintenance history,
replacement schedule, and other
factors. If it’s time for a plane to
be retired, then it may be parked
permanently, sold for parts, or
disassembled for recycling.
The process of putting a
plane out to pasture varies by
situation. “US Airways hasn’t
had to ‘retire’ an aircraft in
several years because most of the
aircraft in our fleet are leased,”
says David Lin, director of fleet
administration. When a leased
plane is past its prime, the airline will simply not renew its
lease and then return the plane
to its owner. “Then it’s up to the
leasing company who owns the
aircraft to determine if it should
be retired,” Lin says.
