Supporting force for flight in an atmosphere
Acts perpendicular to the relative wind
Generated through Bernoulli’s Principle and
Newton’s Law
As a fluid passes through a pipe that narrows
or widens, the velocity and pressure of the
fluid vary. As the pipe narrows, the fluid flows
more quickly. Surprisingly, Bernoulli's
Principle tells us that as the fluid flows more
quickly through the narrow sections, the
pressure actually decreases rather than
increases!


The acute angle between the chord line of the
airfoil and the direction of the relative wind
At angles less that the critical angle of attack,
an increase in the angle of attack will increase
lift provided that all other factors are the
same

Fuselage

Truss – internal structure with non-load carrying skin
Semi-monocoque – inside formers & stringers


Provides all the lift that supports aircraft in flight


Vertical stabilizer – directional balance
Rudder – direction of yaw
Horizontal stabilizer – longitudinal balance
Elevator – controls the pitch

Rudder - yaw about the vertical axis



Bank the aircraft in order to change the
direction of flight
Rudder yaws but does not create the unbalance of
forces needed to change direction
 Slip – tail inside
 Skid – tail outside

Adverse yaw
Raised wing creates more lift and more drag.
Aircraft tries to turn opposite the turn.
 creates added drag

Horizontal turns
Lift vector is tilted
 Creates an acceleration



Shallow - 0 to 20 degrees of bank
Medium – 20 to 45 degree of bank
Steep – more than 45 degree of bank
Apply coordinated aileron and rudder initially
for the turn, then increase back pressure,
once the turn is established pressure on
controls can be relaxed

The raised wing creates more lift than the
lowered wind. Especially in steeper turns the
lift on the raised wing will continue to
increase and will need aileron applied
opposite the turn in order to correct.

Extending the flaps increases:
Wing camber
Wing area (some types)
Angle of attack of the wing
These changes increase lift and drag (induced and
parasite
Allows the pilot to make a steeper approach without
increasing airspeed
May provide increased lift required for certain
maneuvers


An airplane will fly as long as the wing is
creating sufficient lift to counteract the load
imposed on it
The angle of attack at which a wing stalls
regardless of airspeed, flight attitude, or
weight is known as the critical angle of attack
The direct cause of every stall is an excessive angle
of attack
The smooth flow of air over the top of the wing is
disturbed at this critical angle of attack
The stalling speed of a particular airplane is not a
fixed value for all flight situations
A given airplane will always stall at the same angle
of attack regardless of airspeed, weight, load
factor, or density altitude
The angle is typically from 16-20 degrees,
depending on the airplane’s design

The critical angle of attack can be exceeded
at any attitude or airspeed
At low airspeed, the angle of attack will tend to be
high
Abrupt control application and/or higher bank
angles will be involved with exceeding the critical
angle of attack at higher airspeeds or lower pitch
attitudes

Recovery from a stall requires the pilot to
reduce the angle of attack to allow the
smooth air over the wing to begin again
Considerable altitude may be lost during recovery


A spin may be defined as an aggravated stall
that results “autorotation” and the airplane
follows a downward corkscrew path
The “autorotation” results from an unequal
angle of attack on the airplane’s wings
The rising wing is less stalled
The descending wing has exceeded the critical
angle of attack and is more stalled

Spins may occur during stalls with a sideslip
or yaw acting on the airplane at the time of
the stall




Entry - stall
Incipient – lasts about 4 to 6 seconds
approximately 2 turns
Developed – airspeed vertical speed, and rate
of rotation are stabilized. Altitude loss
approximately 500 feet each 3 second turn
Recovery - wings regain lift recovery in about ½
to ¼ turn after anti-spin inputs are applied






Reduce the throttle to idle
Position the ailerons to neutral
Apply full opposite rudder
Apply positive forward movement of the
elevator forward of neutral to break the stall
After spin rotation stops, neutralize the
rudder
Begin applying back pressure to raise the
nose to level flight


Spin avoidance and recovery require positive
control applications
Intentional spins should only be practiced
within the limitations of a properly rigged
airplane with a qualified instructor at an
altitude allowing recovery prior to descent
below 3000ft AGL


Stability - the inherent quality of an airplane
to correct for conditions that may disturb it
from equilibrium

Controllability - the airplane’s capability
to respond to a pilot’ control inputs

Maneuverability - the ability of the aircraft
to change direction about the three exes and
withstand the forces imposed by the
maneuver

Positive – when moved out of equilibrium the
more likely it is to return to equilibrium

Neutral – when moved out of equilibrium it
will tend to stay in the new position

Negative – when moved out of equilibrium the
more likely it is to continue in the new direction




In inherently stable aircraft returns to it’s
original position after being disturbed
The location of the center of gravity (CG)
determines the longitudinal stability
Too much stability is detrimental to
maneuverability
Too little stability can be detrimental to
controllability

Stability - the inherent quality of an airplane

Controllability - the airplane’s capability


Maneuverability - the ability of the aircraft
to change direction about the three exes and


The result over time when reacting to a
disturbance from equilibrium
Dynamic stability requires positive static
stability as the initial reaction
An aircraft with positive dynamic stability will tend
to return to equilibrium through smaller and
smaller oscillations
An aircraft with neutral dynamic stability will tend
to continue oscillation with the same magnitude for
each oscillation
An aircraft with negative dynamic stability will
continue oscillating with the magnitude of each
oscillation increasing


Dihedral is the angle at which the wings are
slanted upward from the root to the tip
Dihedral’s stabilizing effect is the result of a
slight sideslip which occurs when one wing is
forced down
The sideslip creates a difference between the angle
of attack on the upper and lower wings with the
lower wing having a greater angle of attack
(creating more lift) and raises the lowered wing

By over-controlling/correcting the aircraft the
pilot disturbs the inherent stability creating
oscillations that increase in magnitude until
the aircraft become impossible to control

The condition of improved performance
encountered when the aircraft is near the
ground (approximately a wing span)
The ground changes the airflow around the wing
and creates a cushion of air
 This reduces the upwash, downwash, and
wingtip vortices
 Results in a reduction of induced drag

Good stuff
Allows the pilot to reduce wear and tear on the
aircraft and increase acceleration when operating
from a soft-field
May be utilized to soften a landing

Bad stuff
May allow the aircraft to takeoff before the aircraft
is ready to continue flying which can result in
settling
May cause excessive float on landing

Strongest wake
Heavy (larger AOA)
Clean (no changes in the wing)
Slow (larger AOA)

Jet blast
Exhaust from a jet can flip a light aircraft
Stay back 500 ft.

Wake turbulence avoidance in flight
Avoid 5+ miles behind the aircraft
Avoid 1,000ft below the aircraft

Wake turbulence avoidance landing
Approach above the larger aircraft’s path
Touchdown beyond the larger aircraft’s touchdown
point
Land prior to the larger aircraft’s rotation point
Be cautious of crosswinds that can make them drift

Wake turbulence avoidance departing
Rotate prior to and climb above the flight path
Wait 2-3 minutes if departing for dissipation
A load is a force which is supported by the
wings of the aircraft
the load in straight-and-level unaccelerated flight is
the weight of the aircraft and its contents (1 G)

A load factor is a ratio of the total load
supported by the wings to the actual weight
of the aircraft and its contents
Also referred to as G’s (gravities)

Climbing or turning will increase the G load
The load factor in turning flight is determined by
the bank angle


In order to maintain level flight during a turn,
the wings must produce enough lift to
support the weight of the aircraft multiplied
by the load factor
The increased angle of attack required to
produce the extra lift at any given bank angle
will increase the stall speed of the aircraft
(multiply the stall speed by the square root of the
load factor to determine the higher stall speed)

Utility = +4.4/-1.76
Acrobatic = +6.0/-3.0
Transport = +2.5 to +3.8/-1.0




Va – the maximum speed that the aircraft will
stall before a damaging load factor results
or
the maximum speed at which full of
abrupt control movements may be used
without overstressing the aircraft
Va changes with the weight of the aircraft
Va is typically published for max gross weight
(at weights less than max Va is lower)

Vertical air currents or gusts may impose an
increased load factor on an airplane
These gusts are felt by the pilot and passengers as
turbulence
The aircraft’s speed must be kept below Vno
(normal operating range) in any turbulence to
prevent damage
It should be kept below Va in severe of greater
turbulence to allow an additional safety factor
