3240 Final written Flashcards
what are the pitot static instruments
airspeed indicator
vertical speed indicator
altimeter
what are the gyroscopic instruments
turn coordinator
heading indicator
attitude indicator
what is a spin
a spin is when one wing is more stalled than the other
stall + yaw = spin
asymmetric stall where the inside wing stalls first
what is the spin recovery in the Seminole and why is it what it is?
Power
Rudder
Elevator
Aileron
It’s based off the manufacture recommendations
what are the 5 main types of NOTAMS and what are they
- NOTAMS (D) : local and distant
- FDC : instrument changes (approaches and such)
- Pointer NOTAM : just points to another NOTAM
- SAA NOTAM : special activity airspace
- Military
what are the 2 subparts of NOTAM D
U : outside source and has not yet been verified
O : doesn’t fall under any specific type, but could be beneficial to pilots
what is CFIT
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.
what are the hazardous attitudes and their antidotes
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
what is the load factor at 60 degrees
2Gs
what is the load factor for the normal category when flaps are up?
3.8G
what is the load factor for the normal category when flaps are full?
2.0G
what is the load factor for the normal category wen it is pulling negative Gs
-1.5G
what are the 2 different kinds of drag
parasite drag
induced drag
what are the 3 different kinds of parasite drag are there?
Skin Friction Drag
Form Drag
Interference Drag
explain skin friction drag
results of the aircraft surface being rough
ex. swimmers wearing swim caps - it improves performance and fuel efficiency
explain form drag
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
explain interference drag
mixing of airflow streamlines between airframe components such as the wing and the fuselage or the landing gear strut and the fuselage.
what is wake turbulence
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
what are the prop settings of a feathered engine
High Pitch Low RPM
what are the prop settings of a unfathered engine
low pitch high RPM
what are all of the Vmc factors
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
list all of the Vmc speed effects on the Vmc factors
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
what is the acronym for the critical engine factors
PAST
explain the P in the critical engine factors and what it effects
P-Factor =
the descending blade on a propeller produces more thrust than the ascending blade
effects: yaw
explain the A is the critical engine factors and what it effects
Accelerated slipstream =
air that is accelerated by the propeller. the descending blade produces more accelerated slipstream than the ascending blade
affects : roll and pitch
explain the S in the critical engine factors and what it effects
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
explain what the T is in the critical engine factors and what it affects
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
