R44 PRIVATE PILOT EXAM QUESTIONS AND ANSWERS RATED A+
ROTOR SYSTEMS - Answers RIGID, SEMI RIGID, FULLY ARTICULATED
DISSYMMETRY OF LIFT - Answers THE UNEQUAL LIFT ACROSS THE ROTOR DISK RESULTING FROM THE
DIFFERENCE IN THE VELOCITY OF THE AIR OVER THE ADVANCING BLADE HALF AND THE VELOCITY OF AIR
OVER THE RETREATING BLADE HALF OF THE ROTOR DISK
TRANSVERSE FLOW EFFECT - Answers THE CONDITION OF INCREASED DRAG AND DECREASED LIFT IN
THE AFT PORTION OF THE ROTOR DISK CAUSED BY THE AIR HAVING A GREATER INDUCED VELOCITY AND
ANGLE IN THE AFT PORTION OF THE DISK
LTE AND HIGH WIND PEDAL TURNS - Answers LOSS OF TAIL ROTOR EFFECTIVENESS: WIND AT
285-315 (MAIN ROTOR VORTEX INTERFERENCE)
120-240 (WEATHERCOCK STABILITY)
210-330 (TAIL ROTOR VORTEX RING STATE)
RETREATING BLADE STALL - Answers A STALL THAT BEGINS AT OR NEAR THE TIP OF A BLADE IN A
HELICOPTER BECAUSE OF THE HIGH ANGLES OF ATTACK REQUIRED TO COMPENSATE FOR
DISSYMMETRY OF LIFT. STAY AWAY FROM Vne
SETTLING WITH POWER - Answers AKA VORTEX RING STATE... HELICOPTER IS SETTLING INTO ITS OWN
DOWNWASH OR DIRTY AIR
LOW RPM RECOGNITION AND RECOVERY - Answers DECREASE IN ROTOR RPM, FULL DOWN COLLECTIVE
LOW G RECOGNITION AND RECOVERY - Answers THE FEELING OF WEIGHTLESSNESS, AN IMBALANCE OF
FORCES. APPLY AFT CYCLIC AND RELOAD THE ROTOR THEN LEFT OR RIGHT CYCLIC TO LEVEL OUT THE
PITCH
DYNAMIC ROLLOVER - Answers THE TENDENCY OF A HELICOPTER TO CONTINUE ROLLING WHEN THE
CRITICAL ANGLE IS EXCEEDED, IF ONE GEAR IS ON THE GROUND AND THE HELICOPTER IS PIVOTING
AROUND THAT POINT
ANGLE OF ATTACK - Answers THE ANGLE BETWEEN THE AIRFOILS CHORD LINE AND THE RELATIVE WIND
BASIC EMPTY WEIGHT - Answers THE WEIGHT OF THE STANDARD HELICOPTER, OPERATIONAL
EQUIPMENT, UNUSABLE FUEL, AND FULL OPERATING FLUID, INCLUDING FULL ENGINE OIL
BLOWBACK - Answers THE TENDENCY OF THE ROTOR DISK TO TILT AFT IN TRANSITION TO FORWARD
FLIGHT AS A RESULT OF UNEQUAL AIRFLOW
, INDUCED FLOW - Answers THE COMPONENT OF AIR FLOWING VERTICALLY THROUGH THE ROTOR
SYSTEM RESULTING FROM THE PRODUCTION OF LIFT
PRESSURE ALTITUDE - Answers THE HEIGHT ABOVE THE STANDARD PRESSURE LEVEL OF 29.92" Hg.
OBTAINED BY SETTING THE ALTIMETER TO 29.92"
DENSITY ALTITUDE - Answers PRESSURE ALTITUDE CORRECTED FOR NONSTANDARD TEMPERATURE
VARIATIONS
TRANSLATING TENDENCY - Answers THE TENDENCY OF A SINGLE ROTOR HELICOPTER TO MOVE
LATERALLY DURING HOVERING FLIGHT... TAIL ROTOR DRIFT
TRANSLATIONAL LIFT - Answers THE ADDITIONAL LIFT OBTAINED WHEN ENTERING FORWARD FLIGHT,
DUE TO THE INCREASE EFFICIENCY OF THE ROTOR SYSTEM
TRUE ALTITUDE - Answers THE ACTUAL HEIGHT OF AN OBJECT ABOVE MEAN SEA LEVEL
ABSOLUTE ALTITUDE - Answers THE ACTUAL DISTANCE AN OBJECT IS ABOVE THE GROUND
CTAF - Answers COMMON TRAFFIC ADVISORY FREQUENCY
AWOS/ASOS - Answers AUTOMATED WEATHER OBSERVING SYSTEM
