This report is focused on a research question ''How aircraft's are manoeuvred
both on air and on ground flight'', and "how aircraft's try to be
efficient". In this case the aircraft which my report would be focusing on
is the RAF Vigilant T1, a Glider/Air Experience Flight (G/AEF) used by the Air
Training Corps; this means it is both capable of being a normal aircraft but
also a glider.

To answer the question ''How aircraft's are
manoeuvred both on air and on ground flight''; the information is found in ACP
33 Volume 2 on Principles of Flight, first of all I am going to break it down
by answering the question on air only so that you can easily understand.
Aircraft's as a matter of fact are manoeuvred
in air using 3 main axes'; one of which is the longitude, vertical/normal and
horizontal axis.
1) The longitudinal axis is responsible for the
rolling movement of the aircraft, normal for the yaw and lateral for the
pitching. To roll is a movement by the wings to raise one side and to drop one
side to get a left or right roll, which runs along the longitudinal axis.
2) To yaw is a movement where by the whole
aircraft moves side to side on its centre of gravity where all points meet on
the normal axis.
3) Finally to pitch is a movement where the nose
of the aircraft moves up and down on its lateral axis.
There are actually controls which enable the
roll, yaw and pitching movement, the controls are called the ailerons,
elevators and the rudder which are all external parts. To roll the
aircraft the movement of the ailerons are used which is simply to push the
control column to the left or to the right, similarly to yaw the aircraft uses
the rudder by simply pushing on the right pedals to yaw right or vice versa.
Finally to pitch is simply the movement where by the nose of the aircraft moves
up or down using elevators, the pitch movement is controlled by pulling back on
the control column to pitch up and push forwards to pitch downwards.
On the
ground the controls for movement around the airbase really depends on the
type of aircraft or what it has just been through or about to do; in this
case I am still going to focus on the Vigilant T1. As it is a small light
aircraft that does not require a Jeep to pull it around with a wing span of
17.4 metres; the propeller is used to apply thrust to the aircraft. They are
manoeuvred depending on the day before they start with a brief from the admin
of the airbase, normally aircraft's fly against the wind and
depending on the weather this also means creating a certain course around the
airfield. This is how aircraft's are manoeuvred but in a different
prospective where how aircraft's move from one place to another is
similar to flying, but only the controls of thrust and yaw are used for the
simple reasons that one direction is only being used.

Now I will answer how aircrafts such as the
Vigilant T1 try to be as sustainable as possible or also known as economically
friendly. One of the ways in which this is done is the way the aircrafts has
been designed, as you would see modern aircrafts has a more streamlined shape
than all the other old aircraft designs. This is not obvious but the less the
streamlined and aircraft is the more drag it created, this intern makes the
aircraft use more fuel than necessary.
Having a streamlines aircraft does not just
have an advantage of being a bit more economically friendly but it also allows
the aircraft to travel at much faster speeds, in this case the Vigilant T1 is
able to save a lot of fuel as it is able to glide due to its aerodynamic shape;
it used its long wing span of 17.4 metres which make it really friendly to the
environment compared to some other aircrafts.
Another point which makes the Vigilant and
modern aircrafts today very strong and efficient is the way they structure
their wings; a factor they have to include is the fact that it needs to be
light, so in this case creating it to be hollow.
Arguments to support my answers are just basic
knowledge and common sense; such as a child would not run with the wind to try
to fly a kite, but they would automatic notice which and how to fly their kite
although not necessarily knowing why.
