AT 144 EXAM 1 QUESTIONS AND ANSWERS 100% CORRECT
What are the four forces on an aircraft? - ANSWER lift
weight
thrust
drag
From the center of gravity, what direction does weight always act? - ANSWER towards the
center of the Earth
What is the name of the line between the leading edge and trailing edge? - ANSWER chord
line
Lift is mainly caused by: - ANSWER Bernoulli's principle of equal and opposite reaction
Angle of Attack and Pitch are the same thing? t/f - ANSWER False
The angle of attack is? - ANSWER angle between chord line and relative wind
During flight under smooth air, relative wind is produced by: - ANSWER the flight path of the
plane
,In straight and level unaccelerated flight: - ANSWER lift equals weight and thrust equals drag
The use of flaps: - ANSWER decreases stall speed
An airplane will stall: - ANSWER high angle of attack
As the angle of bank is increased in a level turn, the stalling speed: - ANSWER increases and
becomes critical
The angle of attack at which an airplane wing stalls will - ANSWER remain the same
What are the three types of parasitic drag? - ANSWER form
skin friction
interference
The phenomenon of ground effect is most likely to result in which problem in an airplane? -
ANSWER becoming airborne before reaching recommended take off speed
As the airspeed of the airplane increases: - ANSWER parasite drag increases & induced drag
decreases
propeller has less efficiency & altitude increases
, What are the 3 axis of flight - ANSWER longitudinal
lateral
vertical
What is the control surface that controls movements about the axis of flight? - ANSWER
Longitude-ailerons
Lateral-elevator
Vertical-rudder
What causes an airplane to climb? - ANSWER excess thrust
When rolling the airplane into a right bank which aileron is up? - ANSWER right
Once an airplane is rolled into a bank it turns because of - ANSWER the horizontal component
of lift
Adverse yaw is a force that is present as an airplane is rolled into or out of a bank and is
caused by: - ANSWER -the drag of the downward deflected aileron
-use rudder to counterbalance
What happens in a skidding turn? - ANSWER too much rudder, rate of turn is too fast for
angle of bank
