My SIFT Exam with Complete Solutions
What are the parts of the test that I will not guess on? And why? - ANS-Simple drawings
Hidden figures
Mechanical comprehension test
Incorrect questions will be subtracted from your overall score.
Hidden Figures Tip - ANS-The hidden figure in each drawing will always have the same
size and posterior as the shape in the answer choice.
Aviation information - ANS-
What parts of the test should I make an educated guess? - ANS-Army aviation
information
Spatial apperception test
Reading comprehension
Math skills test
What is Newton's law of motion also called the law of inertia? - ANS-An object at rest
will stay at rest and an object in motion will remain in motion, at a constant velocity
unless acted upon by an unbalanced force.
What are the four types of friction - ANS-Sliding or Kingston friction
Fluid friction
Rolling friction static friction
What do the pedals do - ANS-The anti torque pedals the pilot is able to adjust the pitch
of the tail rotor this changes the direction the nose of the helicopter is pointed
What does the throttle do - ANS-Throttle control usually takes the form of a motorcycle
style rotating grip. You can increase the amount of power generated by the engine. The
purpose of doing this is to ensure the heli has the right amount of lift.
, Fun fact. In dual engine aircraft there is usually 2 throttles
Flight maneuvers - ANS-
What are the four basic flight maneuvers - ANS-Straight and level flight
Turns
Hovering
Climbs and descents
What is. Straight and level flight and how do you do it - ANS-When a helicopter moves
at a steady altitude and heading.
Achieved by tilting the nose forwards
The lower the nose the more power required
How are turns achieved - ANS-By pushing the cyclic in the desired turning direction.
Which causes the rotor to tilt. The anti torque and throttle controls are used in
conjunction to ensure altitude is maintained and it's smooth
How are climbs and descents achieved - ANS-By Manipulating the collective. This
manipulated the amount of lift cause the helicopter to rise or fall as the pilot desires.
What is hovering - ANS-When helicopter moves as minimally as possible at a constant
heading and altitude
AAIT key concepts - ANS-
Air Flow in Forward Flight - ANS-Airflow meeting each blade varies with the position of
the blade in its circular motion cycle, generating an acceleration revolving in front the tail
towards the nose; and deceleration revolving from the nose toward the tail in its
counterclockwise motion.
What is an airfoil? What is achieved by them - ANS-A surface that contributes to airlift
generation by regulating airflow over its upper and lower surface.
They achieve horizontal stabilization
What is an angle of attack (AOA) - ANS-Angle that depends on the direction of motion
of the blade with respect to air and chord line of an airfoil. For example the angle
between the rotor blade and net wind passing through it.
Angle of incidence (AOI) - ANS-Mechanics angle between chord line do the blade and
the circular plane it is rotating in.
