Q1. The vertical speed indicator (VSI) is fed by:
static pressure
Q2. The Vertical Speed Indicator (VSI) gives:
Immediate trend information and stable climb or descent information after 6 to 12 seconds (depending on type).
Q3. The purpose of the IVSI is to:
give an instantaneous indication of the aircraft’s vertical speed when a climb or descent has been initiated.
Q4. The response time of a vertical speed detector may be increased by adding a:
correction based on an accelerometer sensor.
Q5. What does a vertical speed indicator actually measure?
The rate of pressure change.
Q6. The vertical speed indicator reads:
The differential pressure between the capsule pressure and the case pressure.
Q7. The vertical speed indicator of an aircraft flying at a true airspeed of 100 kt, in a descent with a slope of 3 degrees, indicates:
500 ft/min.
Q8. Aircraft with pressurized cabin in flight: When switching to the alternate static pressure source, the pointer of the Vertical Speed Indicator:
indicates a climb, then settles down and reads incorrectly.
Q9. How does lag error in an Instantaneous VSI (IVSI) compare to that in a normal VSI?
It is virtually eliminated by using an acceleration pump.
Q10. Which statement is correct for the Vertical Speed Indicator (VSI) during a climb:
The pressure inside the capsule drops faster than the pressure inside the case.
Q11. The operating principle of the vertical speed indicator (VSI) is based on the measurement of the rate of change of:
Static pressure
Q12. Within a temperature range of +50° and -20° C the VSI is accurate to within limits of:
+/-200 ft/min.
