ATC BASICS BLOCK 2
2026|COMPREHENSIVE Q&A FOR
CERTIFICATION SUCCESS 2026
What is the most common cause of A/C accidents? - correct-answer -Stalls
When does a stall normally occur? - correct-answer -15-20 degrees angle of
attack
Three primary causes of stalls. - correct-answer -insufficient airspeed, excessively
violent maneuvers, severe wind shear
Three primary types of icing. - correct-answer -Structural, Pitot-static, Carburetor
,2|Page
Structural icing does _____ - correct-answer -disrupts smooth airflow over the
wing
Pitot icing does _____ - correct-answer -Loss of airspeed. If static vent ices, will
also lose VSI and altimeter.
Carburetor Ice does _______ - correct-answer -reduces fuel/air flow to engine.
What temp does carburetor Ice normally occur? - correct-answer -20-70 degrees
F
How does icing occur up to 70 degrees F in a carburetor? How do you overcome
carb ice? - correct-answer -Lowered pressure lowers the temp of fuel/air mixture.
Any water vapor will freeze. Cleared by Carb heat.

Lift is created as air flows smoothly over an airfoil. A stall occurs when the ______
of ______ is exceeded. - correct-answer -critical angle, attack
The rotor blade of a helicopter is an airfoil and functions the same as a wing on a
conventional aircraft. Name the three devices that control the rotor blade. -
correct-answer -Throttle, collective, and cyclic
What is a phenomenon resulting from passage of an A/C through the
atmosphere? - correct-answer -Wake turbulence
What are the circular patterns of air when something is generating lift? - correct-
answer -Vortices
, 4|Page
What combo would cause the greatest vortex? - correct-answer -Heavy, clean,
and slow
What is the factor that affects wake turbulence the most? - correct-answer -
Weight
Why does a clean formation allow for a stronger vortex? - correct-answer -More
square footage. Without flaps smaller area of wing loading.
Will an A/C on approach or en route create more wake turbulence? - correct-
answer -Approach
Looking from behind an A/C how does the vortices move? - correct-answer -Right
moves counterclockwise. Left moves clockwise
