Aviation Terminology, Aircraft Components, and Helicopter Fundamentals
Army Aviation Information questions test core terminology, aircraft parts, helicopter systems, and the function of major components.
How to study for the SIFT
Use the seven SIFT subtests as your map: build fast visual accuracy, then rotate aviation knowledge, spatial orientation, reading, math, and mechanical reasoning.
Core concepts
Concept 1
Aviation Terminology, Aircraft Components, and Helicopter Fundamentals questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Rotor
A rotor produces lift in a helicopter by rotating airfoils through the air.
Tail Rotor
A tail rotor counters main-rotor torque and helps control yaw.
Fuselage
The fuselage is the main body structure of an aircraft.
Cyclic
The cyclic changes rotor disk tilt to control movement direction.
Collective
The collective changes blade pitch together to increase or decrease lift.
Anti-Torque Pedals
Anti-torque pedals control yaw by changing tail rotor thrust.
Airfoil
An airfoil is a shaped surface that produces lift as air flows around it.
Torque
Torque is rotational force that tends to turn the fuselage opposite the rotor system.
Swashplate
The swashplate transfers collective and cyclic inputs to rotating rotor blades.
Rotor Mast
The mast transmits torque from the transmission to the rotor hub.
Transmission
A helicopter transmission reduces engine rpm and routes power to rotors and accessories.
Freewheeling Unit
A freewheeling unit lets the rotor turn faster than the engine during autorotation.
Rotor Disk
The rotor disk is the circular area swept by the rotating blades.
Tandem Rotors
Oppositely rotating tandem main rotors balance torque without a conventional tail rotor.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
Check-up Questions
A pilot raises one cockpit control and every main-rotor blade gains roughly equal pitch. Which control was moved?
Moving the cyclic forward primarily produces which rotor response?
