ATE 207 Q1 Exam Questions and
Answers Graded A+
AC 20-37E - Correct answer-This AC is intended to provide supplementary
guidance on propeller maintenance and service methods when such guidance is
lacking from the manufacturer or is not consistent with current practice
Prop - Correct answer-produces thrust by accelerating a large mass of air through a
small change in velocity
Jet - Correct answer-produces thrust by accelerating small mass of air through a
large change in velocity
Blade Face - Correct answer-the flat side of a propeller blade (faces aft)
Blade Back - Correct answer-the cambered or curved side of a propeller blade
Blade Thickness - Correct answer-distance between the back and face surfaces
the effective pitch - Correct answer-The actual distance a propeller moves forward
through the air during one revolution is known as

, Geometric pitch - Correct answer-is defined as the distance that a propeller will
move forward in one revolution if it were moving through a solid medium with no
loss of efficiency
Propeller Pitch - Correct answer-is the distance the propeller would move forward
in one rotation if it were moving through a soft solid
Low pitch - Correct answer-Small blade angel
High pitch - Correct answer-Large blade angle
the hub center line - Correct answer-Propeller blade stations are measured from
hub to tip - Correct answer-Propeller blade station numbers increase from
a specified blade station - Correct answer-Measuring propeller blade angle is done
at
a propeller protractor - Correct answer-Propeller blade angle is measured by
Two-position - Correct answer-makes available only two pitch settings
Multi Position - Correct answer-makes any pitch setting within limits possible
automatic - Correct answer-provides a pitch-setting control by some automatic
device
