set of verified questions and expert-corrected
answers
Vertical stabilizer - correct answer to control yaw.
Horizontal tail structure consists of _____ - correct answer horizontal
stabilizer and elevators
Horizontal stabilizer - correct answer at the front end of the tail structure;
prevents the aircraft from pitching up and down
Elevators - correct answer part on a plane's tail that makes the plane go
up and down; hinged to the horizontal stabilizer
Trim tabs - correct answer on the trailing edges of the wings toward the
fuselage, the rudder, and the elevators. Act as a secondary flight control
system, helping to offset an undesirable altitude of the aircraft and relieving
pressure on the controls
Primary flight control system - correct answer manages ailerons,
elevators, and rudder. Designed for the safe maneuvering of the aircraft
and the elimination of over-controlling measures introduced by the pilot
Secondary flight control system - correct answer manages the flaps,
leading edge devices, spoilers, trim tabs, assist the pilot in optimizing
aircraft performance during flight
,Coordinate movement - correct answer throttle-increases/decreases
power
Joystick/control wheel-directs the aircraft left, right, nose up, nose down
Pedals- shift the rudder, which moves the aircraft left or right
4 fundamental flight maneuvers - correct answer straight and level flight,
turns, climbs, and descents
Straight and level flight - correct answer main maneuver, wing tips even
with horizon, constant heading and altitude is maintained
Turns - correct answer ailerons should be banked toward direction of the
turn. To return to level flight, the vertical lift component must equal the
weight of the aircraft. (3 types: shallow, medium, steep)
To perform a turn, actions required are: - correct answer 1. The pilot
moves the stick (cyclic) to the left for lefts turns or right for right turns
2. Enough power or pitching up is also added to counteract the loss of lift
3. The controls are neutralized to stop any increase in the bank angle and
to maintain the desired bank angle
4. After the turn is accomplished, the ailerons are leveled to resume flight
Shallow turn - correct answer bank of less than 20 degrees; after this turn,
the stability of an aircraft naturally returns to level flight without pilot
interference
Medium turn - correct answer bank roughly 20-45 degrees; pilot must
input aileron pressure to return the aircraft to level flight
,Steep turns - correct answer any bank greater than 45 degrees; after a
steep turn the pilot must input opposite pressure on the controls to return
the aircraft to level flight
Climbs - correct answer when an aircraft flight path changes from a lower
to a higher level in altitude. Pilot must increase lift to overcome the aircraft's
weight (if not, results in decrease of airspeed; to correct, input thrust)
Normal climb (cruise climb) - correct answer performed within the aircraft
manufacturer's standards; the aircraft increases airspeed, but it my not be
operating at its optimum performance
Best rate of climb - correct answer gaining the most altitude in a given
amount of time using the most power available to reach cruising altitude
(vy). Steeper than a normal and results in greatest altitude gain over a set
amount of time. Used during takeoff or when needs to gain altitude quickly
Best angle of climb - correct answer gaining the most altitude over a given
distance. Used during takeoff, but also at airports where there are
obstructions in the flight path. Navigating obstacles requires this
Descents - correct answer the opposite of a climb. Engine power levels
must be reduced to maintain airspeed and avoid an excess speed situation
Partial power descent - correct answer preferred way to decrease altitude.
Aircraft should drop at a rate of 500 feet per minute
Minimum safe airspeed (msa) - correct answer a nose-high controlled
descent used to clear obstacles on a short runway. Aircraft's angle is
steeper than during a partial power descent.
, Emergency descent - correct answer occurs when an aircraft rapidly loses
altitude
Percent of change formula - correct answer percent of change=amount of
change/original amount
Percentages - correct answer part=whole x percent
Percent=part/whole
Whole=part/percent
Midpoint formula - correct answer (x₁+x₂)/2, (y₁+y₂)/2
Distance formula - correct answer d = √[( x₂ - x₁)² + (y₂ - y₁)²]
Quadratic equation - correct answer
Quadratic equation axis of symmetry (x point of vertex) - correct answer
x=-(b/2a)
Quadratic formula - correct answer x = -b ± √(b² - 4ac)/2a
Supplementary angles - correct answer two angles whose sum is 180
degrees
Complementary angles - correct answer two angles whose sum is 90
degrees
