Altimeter v. VSI
If an aircraft holds a steady altitude
A. The altimeter reads a constant height, and the VSI reads zero.
B. The altimeter reads a non-zero height, and the VSI reads zero.
C. The altimeter reads a constant height, and the VSI doesn't have a reading because it isn't climbing or descending.
A
If the Pitot tube becomes completely blocked by ice, but the static port remains open, what will happen to the Airspeed Indicator during a climb?
A. The ASI will drop to zero immediately.
B. The ASI will "freeze" at its current speed and never move.
C. The ASI will act like an altimeter, showing an increase in airspeed as the altitude increases.
D. The ASI will show a decrease in airspeed as the altitude increases.
c
what is the power source for the altitude and heading indicator?
a. vacuum..
b. pressure from outside
c. electronic
d. from the motor
Altimeter displays_____ and the VSI displays____
A. Height from sea level, height difference
B. Absolute height, direction of descent and climb
C. Absolute height, speed of change.
C
On a standard color-coded Airspeed Indicator, what does the lower limit of the white arc represent?
A. Vso - stall speed flaps and gears down
B. Vfe - max speed with flaps deployed
C. Vno - max cruising speed
A
Where is the airspeed indicator in a cessna
a. top right
b. top left
c. middle
d. somewhere in the bottom
top left corner
What are the two different types of pressure that the vertical speed indicator uses to measure the rate of descent or climb?
Compares immediate static pressure with a "calibrated leak" (delayed pressure) to measure rate.
A pilot is flying in the Northern Hemisphere and initiates a turn from a Northern heading toward the East. What will the compass do?
A. Move ahead of the actual turn
B. Lag significantly behind the turn..
C. Spin rapidly in a complete circle due to centrifugal force.
D.Remain perfectly steady until the turn is completed.
B
If a vacuum system failure occurs what two instruments will most likely become unreliable?
A. Attitude Indicator and Heading IndicatorC. Altimeter and Airspeed Indicator
D. Heading Indicator and Vertical Speed Indicator
A.
What port is blocked when the altimeter freezes, and the VSI slowly goes to zero.
A. Pitot
B. Static
Static
Explain how the Airspeed Indicator uses the pitot pressure?
The ASI measures the difference between air pressure from the Pitot tube and static air pressure from the static port. The static pressure outside acts as a reference. This pressure difference, known as dynamic pressure, is linked to the needle on the dial to show how fast the airplane is moving.
what is rigidity in space?
Rigidity in space refers to the tendency of a spinning gyro rotor to remain in a fixed position in the plane in which it is spinning, resisting outside forces; this allows instruments like the Attitude Indicator to stay level as the airplane moves around them.
How does the VSI work?
Uses a sealed capsule that expands/contracts with changing air pressure.
Why does a magnetic compass provide inaccurate readings during a rapid acceleration or deceleration on an East or West heading?
Acceleration Error. In the Northern Hemisphere, the rule is ANDS: Accelerate North, Decelerate South. When you accelerate, the compass swings toward North; when you slow down, it swings toward South.
Which gyroscopic instrument is typically the only one that serves as a primary source of bank information and is 'self-erecting' to stay parallel to the natural horizon?
A. Heading IndicatorB it uses rigidity in space to stay that way
