Aerodyne
All
heavier-than-air flying tool deriving lift from
motion whose lift is obtained by means
of aerodynamic loads.
An aerodyne has
lift only if it is dynamic: it draws it from the
movement.
Planes, sailplanes or gliders, kites,
the autogiros and
the helicopters are aerodynes in
opposition to airships of which lift,
said static, result from the use of
a gas lighter than the air.
The aerodynes have surfaces known as lifting
surfaces which include:
(1) airfoil
or aerofoil is a part or surface, such as a wing, propeller blade,
or rudder, whose shape influences control, direction,
thrust, lift, or propulsion; it is a surface designed
to produce lift from the movement of air over on
it; ideally, it should present the greatest amount
of lift with the least amount of drag.
(2) empennages, at the tail portion of an aircraft, made up of horizontal, vertical
or obliques surfaces which make it possible to
ensure the stability and the control of the flight dynamics: pitch, roll and yaw.

Icarus oath
Icarus History
Icarus
was the son of the inventor Daedalus and a slave
named Naucrate. King Minos of Crete imprisoned Daedalus
and Icarus in the Labyrinth to punish Daedalus for
helping the hero Theseus to kill the monster called
the Minotaur and to escape with Minos' daughter,
Ariadne. Daedalus knew that Minos controlled any
escape routes by land or sea, but Minos could not
prevent an escape by flight. So Daedalus used his
skills to build wings for himself and Icarus. He
used wax and string to fasten feathers to reeds of
varying lengths to imitate the curves of birds' wings.
When
their wings were ready, Daedalus warned Icarus to fly
at medium altitude. If he flew too high, the sun could
melt the wax of his wings, and the sea could dampen
the feathers if he flew too low.
Once
they had escaped Crete, Icarus became exhilarated
by flight. Ignoring his father's warning, he flew
higher and higher. The sun melted the wax holding
his wings together, and the boy fell into the water
and drowned. Daedalus looked down to see feathers
floating in the waves, and realized what had happened.
He buried his son on an island which would be called
Icaria, and the sea into which Icarus had fallen
would ever after be called the Icarian Sea (between
the Cyclades and Asia Minor).

The (pilot) oath
Conscious of the privilege that the
joys of the flight constitute:
-
I will never forget the responsibilities which
result from this, to ensure the safety of my possible
passengers and people on the ground.
-
I will rigorously respect the regulations and the
principles of deontology applicable to my flying activity,
from the preparation to the execution of flight.
-
I will endeavour to maintain and improve my theoretical
and technical training.
-
I will know the limits of my competences and those
of the material, and will take care not to exceed them.
-
I will prepare a possible flight of demonstration
with meticulousness while endeavouring not to approach
the limits of the machine.
-
Being given the extent of the consequences of a failure
of my share, I will supervise my physical and moral
health particularly, and will abstain from in particular
drinking alcohol before flying.
-
If I take along a passenger, I will not omit to clarify
the situation with respect to the insurances. I will
never seek to dazzle it and even less to frighten him
or her.
-
I will announce any breakdown or deterioration, repaired
or not, to the person in charge for the material, like
any incident likely to interest safety.
-
I will always respect the principles of courtesy
and solidarity which animate the life of the aeronautical
community and ensure its reputation.
-
I will make benefit from my experience the least
experienced and I will attentively listen to those
which are more.
-
I will
have thus contributed to reinforce the safety of
the aeronautical sports and to improve the image
that the public make of it.
