Vertical speed indicator & ASI only.

Airspeed indicator, VSI and altimeter.

6. If the static source to an airspeed indicator (ASI) becomes blocked during a descent the instrument will

over-read

continue to indicate the speed applicable to that at the time of the blockage

read zero

7. If static source of ASI is blocked during level flight, ASI will

Will read correct

Uder-read

Over-read

10. A pilot tube covered by ice which blocks the ram air inlet will affect the following instrument (s)

airspeed indicator only.

altimeter only.

vertical speed indicator only.

11. Dynamic pressure is

Pitot pressure minus static pressure

12. Dynamic pressure sensed by or pitot tube : Today's airspeed indicators (calibrated to the Saint-Venant formula), Indicate, in the absence of static (and instrumental) error

Increases if air density decreases

Increases if air density increases

Is not affected by the density of surround up air.

13. The Airspeed Indicator measures

Static pressure changes

Static pressure

14. If the static line to the ASI becomes blocked during a climb, the ASI reading will

remain fixed.

progressively under read.

progressively over read.

higher than the true airspeed (TAS)

independent of the true airspeed (TAS)

equal to the true airspeed (TAS)

18. VNO is the maximum speed

with flaps extended in landing position.

not to be exceeded except in still air and with caution.

At which the flight controls can be fully deflected.

19. How many disphragms are present in a basic Mach meter?

Three.

Four.

Two.

20. A pilot blockage of both the ram air input and the drain hole with the static port open causes the airspeed indicator to

read a little low

freeze at zero

React like an altimeter
