Q

what is a spin

A

a spin is when one wing is more stalled than the other
stall + yaw = spin
asymmetric stall where the inside wing stalls first

Q

what is CFIT

A

Controlled Flight into Terrian
An unintentional collision with terrain (the ground, a mountain, a body of water, or an obstacle) while an aircraft is under
positive control.

Q

what are the hazardous attitudes and their antidotes

A

Resignation = I am not helpless, I can make a difference
Anti - authority = follow the rules, they are usually right
Impulsivity = not so fast, think first
invulnerability = it could happen to me
Macho = taking chances are foolish

Q

explain skin friction drag

A

results of the aircraft surface being rough
ex. swimmers wearing swim caps - it improves performance and fuel efficiency

16
Q

explain form drag

A

results of an objects general shape in relation to the relative wind
ex. stuck your hand out the window of the car
- high wing v low wing

17
Q

explain interference drag

A

mixing of airflow streamlines between airframe components such as the wing and the fuselage or the landing gear strut and the fuselage.

18
Q

what is wake turbulence

A

is a function of an aircraft producing lift, resulting in the formation of two counteracting vortices trailing behind the aircraft

  • when landing behind a bigger aircraft, stay inside the bowl.
    – land shorter than the previous aircraft
    – takeoff before the previous aircraft
19
Q

what are the prop settings of a feathered engine

A

High Pitch Low RPM

20
Q

what are the prop settings of a unfathered engine

A

low pitch high RPM

21
Q

what are all of the Vmc factors

A

Standard day at sea level
Max. gross takeoff weight
Aft legal center of gravity
Critical engine inop and windmilling
Flaps and gear up (clean config)
Up to 5 degrees bank into op engine
Max power on the operating engine

22
Q

list all of the Vmc speed effects on the Vmc factors

A

standard day = Increase
max. gross takeoff = Increase
aft legal CG = Increase
critical engine windmilling = Increase
flaps and gear up = Increase
up to 5d bank = Decrease
max power on op = Increase

23
Q

what is the acronym for the critical engine factors

A

PAST

24
Q

explain the P in the critical engine factors and what it effects

A

P-Factor =
the descending blade on a propeller produces more thrust than the ascending blade
effects: yaw

25
Q

explain the A is the critical engine factors and what it effects

A

Accelerated slipstream =
air that is accelerated by the propeller. the descending blade produces more accelerated slipstream than the ascending blade
affects : roll and pitch

26
Q

explain the S in the critical engine factors and what it effects

A

Spiraling slipstream =
slipstream off the propeller doesn’t flow back in a straight line. the pressure differential between the faster and slower moving air causes a pressure differential
effects : Yaw

27
Q

explain what the T is in the critical engine factors and what it affects

A

Torque =
newtons 3rd law “for every action there is an equal and opposite reaction”
because the propellers rotate clockwise, the airplane has a natural tendency to roll counterclockwise
effects : roll
