Lift and Basic Aerodynamics
• Four forces act upon an
aircraft in relation to
straight-and-level,
unaccelerated flight.
• These forces are thrust,
lift, weight, and drag.

Lift and Basic Aerodynamics
• The position of the CG of
an aircraft determines the
stability of the aircraft in
flight.
• As the CG moves
rearward (towards the tail)
the aircraft becomes more
and more dynamically
unstable.

Lift and Basic Aerodynamics
• One of the most
significant components of
aircraft design is CG.
• It is the specific point
where the mass or weight
of an aircraft may be said
to center; that is, a point
around which, if the
aircraft could be
suspended or balanced,
the aircraft would remain
relatively level.

Chapter 2 – Aircraft Structure
FAA – Pilot’s Handbook of Aeronautical Knowledge
Today’s Mission Requirements
 Mission:

Describe in writing the major components of an aircraft.
Describe in writing the subcomponents of an aircraft.

EQ:

Describe the importance of Aeronautical Knowledge for the student
pilot learning to fly.
Parts of an Aircraft
Major Components
• Although airplanes are
designed for a variety of
purposes, most of them
have the same major
components.
• Most airplane structures
include a fuselage, wings,
an empennage, landing
gear, and a powerplant.
Major Components
Fuselage
• The fuselage is the central
body of an airplane and is
designed to accommodate
the crew, passengers, and
cargo.
• Older types of aircraft
design utilized an open
truss structure
constructed of wood,
steel, or aluminum tubing.
Major Components
Fuselage
• The most popular types
of fuselage structures
used in today’s aircraft
are the monocoque
(French for “single
shell”) and
semimonocoque.
Major Components
Wings
• The wings are airfoils
attached to each side
of the fuselage and are
the main lifting
surfaces that support
the airplane in flight.
Major Components
Wings
• Wings may be attached
at the top, middle, or
lower portion of the
fuselage.
• These designs are
referred to as high-,
mid-, and low-wing,
respectively.
Major Components
Wings
• Airplanes with a single
set of wings are referred
to monoplanes, while
those with two sets are
called biplanes.
Major Components
Wings
• Many high-wing
airplanes have external
braces, or wing struts,
which transmit the
flight and landing loads
through the struts to
the main fuselage
structure.
Major Components
Wings
• Since the wing struts
are usually attached
approximately halfway
out on the wing, this
type of wing structure
is called semicantilever.
• A few high-wing and
most low-wing
airplanes have a full
cantilever wing
designed to carry the
loads without external
struts.
Major Components
Wings
• The principal structural
parts of the wing are
spars, ribs, and
stringers.
• These are reinforced
by trusses, I-beams,
tubing, or other
devices, including the
skin.
Major Components
Wings
• The wing ribs
determine the shape
and thickness of the
wing (airfoil).
Major Components
Wings
•
In most modern
airplanes, the fuel
tanks are either an
integral sealed
compartment part of
the wing’s structure
itself, or they consist of
flexible containers
mounted inside of the
wing.
Major Components
Wings
• Attached to the rear or
trailing edges of the
wings are two types of
control surfaces
referred to as ailerons
and flaps.
Major Components
Wings
• Ailerons extend from
about the midpoint of
each wing outward
toward the tip, and
move in opposite
directions to create
aerodynamic forces
that cause the airplane
to roll.
Major Components
Wings
• Flaps extend outward
from the fuselage to
near the midpoint of
each wing.
Major Components
Wings
• The flaps are normally
flush with the wing’s
surface during cruising
flight.
• When extended, the
flaps move
simultaneously
downward to increase
the lifting force of the
wing for takeoffs and
landings.
