Aerodynamics Flashcards
You are planning an IFR flight and need to verify the VOR equipment operational check was accomplished within the preceding
A) 30 days.
What is the maximum allowable tolerance between the two indicators of a dual VOR system when making a VOR check?
B) 4° between the two indicated bearings of the VORs when tuned to the same ground VOR facility.
If while in level flight, it becomes necessary to use an alternate source of static pressure vented inside the airplane, which of the following variations in instrument indications should the pilot expect?
A) The altimeter will read higher than normal, airspeed greater than normal, and the VSI will momentarily show a climb.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the right from an easterly heading in the Northern Hemisphere?
B) The compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the right from a south heading in the Northern Hemisphere?
B) The compass will indicate a turn to the right, but at a faster rate than is actually occurring.
What should be the indication on the magnetic compass when you roll into a standard-rate turn to the left from a south heading in the Northern Hemisphere?
C) The compass will indicate a turn to the left, but at a faster rate than is actually occurring.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the right from a westerly heading in the Northern Hemisphere?
C) The compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth.
As you roll into a standard-rate right turn from a northerly heading in the Northern Hemisphere, the magnetic compass will
C) initially indicate a turn to the left.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the left from a west heading in the Northern Hemisphere?
A) The compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the left from a north heading in the Northern Hemisphere?
A) The compass will initially indicate a turn to the right.
What is the relationship between centrifugal force and the horizontal lift component in a coordinated turn?
C) Horizontal lift and centrifugal force are equal.
What force causes an airplane to turn?
B) Horizontal lift component.
Which instrument indicates the quality of a turn?
C) Ball of the turn coordinator.
During a constant bank level turn, what effect would an increase in airspeed have on the rate and radius of turn?
B) Rate of turn would decrease, and radius of turn would increase.
Conditions that determine the pitch attitude required to maintain level flight are
B) airspeed, air density, wing design, and angle of attack.
You begin a descent with your static ports iced over. What will be the indication on your VSI?
C) VSI will indicate zero regardless of actual descent rate.
If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will
B) increase and true altitude will increase.
What should be the indication on the magnetic compass as you roll into a standard-rate turn to the left from an east heading in the Northern Hemisphere?
B) The compass will indicate the approximate correct magnetic heading if the roll into the turn is smooth.
During normal operation of a vacuum driven attitude indicator, what attitude indication should you see when rolling out from a 180° skidding turn to straight-and-level coordinated flight?
C) The miniature aircraft shows a turn in the direction opposite the skid.
During normal coordinated turns, what error due to precession should you observe when rolling out to straight-and-level flight from a 180° steep turn to the right?
C) The miniature aircraft would show a slight turn indication to the left.
Errors in both pitch and bank indication on an attitude indicator are usually at a maximum as the aircraft rolls out of a
A) 180° turn.
If a 180° steep turn is made to the right and the aircraft is rolled out to straight-and-level flight by visual references, the attitude indicator
B) may show a slight climb and turn.
One characteristic that a properly functioning gyro depends upon for operation is the
B) resistance to deflection of the spinning wheel or disc.
How should you preflight check the accuracy of your altimeter prior to an IFR flight?
B) Set the current altimeter setting and the indication should be within 75 feet of the airport elevation.
(Refer to figure 144.) What changes in control displacement should be made so that “2” would result in a coordinated standard-rate turn?
A) Increase left rudder and increase rate of turn.
(Refer to figure 144.) Which illustration indicates a coordinated turn?
B) 3.
(Refer to figure 144.) Which illustration indicates a skidding turn?
A) 1.
(Refer to figure 144.) What changes in control displacement should be made so that “1” would result in a coordinated standard-rate turn?
A) Increase right rudder and increase rate of turn.
(Refer to figure 144.) Which illustration indicates a slipping turn?
B) 2.
