SIFT (ARMY AVIATION
INFORMATION) PRACTICE TEST
2025 QUESTIONS AND ANSWERS
The typical structure of a helicopter is a ______ (fill in the blank) with a
____ (fill in the blank) protruding upward out of it. -
....ANSWER ...-Fuselage (the body of the craft), Mast.
The engine of the craft drives power upward through the ____ (fill in
the blank) to the rotor blades, which are controlled by the pilot. -
....ANSWER ...-Mast
This main rotor is used to generate ____ (fill in the blank). -
....ANSWER ...-Thrust.
____ (fill in the blank) is balanced by a second rotor, usually a tail rotor,
which is intended to account for the effects of ____ (fill in the blank). -
....ANSWER ...-Thrust, Torque.

,What are the two main types of aircraft? - ....ANSWER ...-
Rotorcraft and Fixed Wing.
The main advantage of a helicopter over an airplane is its ability to
takeoff ____ (fill in the blank). It can also ____ (fill in the blank). This
means helicopters can be used to takeoff from and land in places that
would be impossible for planes. They can also perform tasks such as
dropping cargo or troops into challenging positions. -
....ANSWER ...-Vertically, Hover.
What are the different Helicopter types? - ....ANSWER ...-Single
Main Rotor, Tandem Rotor, and Coaxial Rotor.
This is the most common design for a helicopter- a ____ (fill in the
blank) rotor generating power, with a secondary rotor, such as a tail
rotor, used to offset the effects of torque. One disadvantage of this
design is that some power is used for countering ____ (fill in the blank),
rather than being used solely for lift. - ....ANSWER ...-A Single
Main Rotor, Torque.
....COPYRIGHT ©️ 2025 ALL RIGHTS RESERVED...TRUSTED & VERIFIED 2
, This helicopter design features two main rotating blade sections: front
and rear. Each set of blades rotates counter to the other, meaning that
torque is automatically offset. There is no need for additional measures,
such as a tail rotor, to deal with torque. Because of this, all of the power
from the engine can be used to lift. Consequently, ____ (fill in the
blank) helicopters are some of the fastest and most powerful in
existence. - ....ANSWER ...-Tandem Rotor Helicopter.
This type of helicopter features two sets of blades rotating above and
beneath each other. The two sets of blades are mounted to the same
mast, but rotate in opposite directions to each other. This has the
advantage of reducing ____ (fill in the blank) and allowing for greater
cargo and passenger capacity as a result. - ....ANSWER ...-Coaxial
Rotor Helicopter, Payload.
____ (fill in the blank) is created by the engine, or engines, of the
helicopter. It is transferred into motion via the ____ (fill in the blank)
and ____ (fill in the blank). Sufficient ____ (fill in the blank) is needed
to overcome the drag and the weight of the helicopter and keep moving
it forward. - ....ANSWER ...-Thrust, Mast and Rotors, Thrust.
