SIFT Exam Questions with Verified
Solutions
A disadvantage of a single main rotor helicopter is? - ANS-The secondary rotor diverts
power to counter torque, rather than being used for lift
Thrust is created by? - ANS-The engine(s) of a helicopter
What are some common helicopter controls? - ANS-Cyclic
Collective
Throttle
Angle of incidence is a mechanical angle between? - ANS-The chord line of the blade
and the circular plane in which it rotates
Blade flapping is used during takeoff to? - ANS-Counter dissymmetry of lift
Airfoils are used to? - ANS-Regulate airflow
Settling with power is also known as? - ANS-Vortex ring state
Bernoulli's principle explains helicopter lift due to? - ANS-Lower pressure occurring over
a wind blade than under it
By moving a cyclic, a pilot is able to? - ANS-Alter the pitch of main rotor blades
Which is the correct order of operations? - ANS-PEMDAS
Multiplying two negative numbers always results in? - ANS-positive number

4, 8, 11, 11, 11, 13, 19, 20, 29, 29, 29 - ANS-13
g + (3xg) + 4y -2y can be simplified as? - ANS-8g +2y
