Preview 4 out of 38 pages

This in-depth study guide contains over 100 fully solved multiple-choice and short-answer questions tailored specifically for the AFAST (Alternate Flight Aptitude Selection Test), required for rotary-wing flight training programs. Developed for the 2025/2026 exam cycle, this comprehensive Q&A collection covers all major theoretical concepts and operational procedures related to helicopter aerodynamics and flight mechanics. Key topics include dissymmetry of lift, translational and ground effect, autorotation, retreating blade stall, collective and cyclic pitch control, density altitude, slope operations, wake turbulence avoidance, gyroscopic precession, and emergency procedures such as engine failure responses. Students will also find detailed explanations of main rotor and tail rotor functions, flight envelope dynamics, center of gravity limits, and performance-affecting conditions like high humidity and high-density altitudes. This resource is especially useful for: U.S. Army flight school applicants Aviation and aerospace engineering students Military helicopter pilot trainees Students preparing for FAA or rotary-wing qualification exams Whether you're pursuing a career in aviation or training for military flight programs, this document offers a practical, exam-ready format to ensure mastery of critical AFAST knowledge areas. Keywords: AFAST, helicopter exam, rotor systems, flight dynamics, cyclic control, collective pitch, autorotation, density altitude, ground effect, wake turbulence, lift and drag, main rotor, tail rotor, dissymmetry of lift, slope operations, quick stop, torque effect, flight envelope, gyroscopic precession, aviation aptitude, flight training

,when departing behind a heavy aircraft the pilot should avoid wake turbulence by

maneuvering the helicopter - 🧠 ANSWER ✔✔Above and upwind from the heavy

aircraft

What actions should you take if engine failure occurs at altitude? - 🧠 ANSWER

✔✔lower the collective pitch control to maintain rotor RPM


during a hover, a helicopter tends to drift right. to compensate for this some

helicopters? - 🧠 ANSWER ✔✔rotor mast is rigged to the left side


if the rpm is low and manifold pressure is high what initial corrective action should

be taken? - 🧠 ANSWER ✔✔lower the collective pitch


high air speeds especially in turbulent air should be avoided because the possibility

of ? - 🧠 ANSWER ✔✔the retreating blade to stall in forward flight, stalls are more

likely to occur under conditions of high gross weight, low rpm, high density

altitude, steep or abrupt turns, and or turbulent flight.


translation lift is the result of? - 🧠 ANSWER ✔✔Airspeed


during surface taxi the collective pitch is used to control? - 🧠 ANSWER ✔✔the

rate of speed. the higher the collective pitch the higher the taxi speed.

, 3


the upward bending of the rotor blades resulting from the combination of lift and

centrifugal forces is known as - 🧠 ANSWER ✔✔coning


the tail rotor produces thrust and is variable through the use of ? - 🧠 ANSWER

✔✔anti torque pedals


medium frequency vibrations would be associated with - 🧠 ANSWER ✔✔defects

in tail rotor

while in cruise level flight, low frequency vibrations (100-400 cycles per minute)

are usually associated with? - 🧠 ANSWER ✔✔always associated with the main

rotor


a stall is the results of ? - 🧠 ANSWER ✔✔exceeding the angle of attack


What is ground effect ? - 🧠 ANSWER ✔✔the result of interference of the surface


the primary purpose of the tail rotor system is to ? - 🧠 ANSWER ✔✔counteract the

torque effect of the main rotor

the most effective method of scanning for other aircraft for collision avoidance

during daylight hours is to use ? - 🧠 ANSWER ✔✔a series of short regularly

spaced eye movements that bring successive areas of the sky into the central visual

, field each movement should not exceed 10 degrees and each area should be

observed for at least one second to enable detection


translation lift is the result of ? - 🧠 ANSWER ✔✔increased rotor efficiency


in a no wind condition, which control is used to change heading? - 🧠 ANSWER

✔✔cyclic control


a helicopter that is improperly loaded with a CG forward of forward limits will ? -

🧠 ANSWER ✔✔*have a nose low altitude * need excessive rearward displacement

of the cyclic to maintain hover

the wind conditions that requires the most caution when avoiding wake turbulence

on landing is - 🧠 ANSWER ✔✔light tail winds because they can move the vortices

of a preceding aircraft forward into the anticipated touch down zone of another

when operating at high forward air speeds, retreating blade stall are more likely to

occur under which conditions? - 🧠 ANSWER ✔✔high gross weight, low rpm, high

density altitude, steep or adrupt turns, and or turbulent flight


to initiate a quick stop ? - 🧠 ANSWER ✔✔aft the cyclic and simultaneously lower

the collective pitch
