Question 1

Which two pressure components are measured by the Pitot-Static system to determine Indicated Airspeed (IAS)?

Total pressure from the pitot tube and static pressure from the static port Dynamic pressure from the static port and ambient pressure from the pitot tube Manifold pressure from the intake and ambient static pressure Barometric pressure from the altimeter capsule and dynamic pressure from the static port

Correct Answer:

Total pressure from the pitot tube and static pressure from the static port

Question 2

What is the primary internal mechanism inside a traditional mechanical Airspeed Indicator (ASI)?

An evacuated sealed aneroid capsule inside an airtight casing A flexible diaphragm receiving pitot pressure inside, surrounded by static pressure inside an airtight casing A Bourdon tube connected directly to the static vent A torque tube driven by a magnetic drag cup

Correct Answer:

A flexible diaphragm receiving pitot pressure inside, surrounded by static pressure inside an airtight casing

Question 3

An altimeter measures height above a selected pressure datum based on which physical law or principle?

Rate of change of static pressure with speed Lapse rate of atmospheric static pressure with increasing altitude Differential dynamic pressure between upper and lower wing surfaces Electromagnetic wave reflection from the Earth surface

Correct Answer:

Lapse rate of atmospheric static pressure with increasing altitude

Question 4

How does a standard mechanical Vertical Speed Indicator (VSI) measure rate of climb or descent?

By comparing pitot total pressure against cabin static pressure By measuring the rate of change of static pressure via a calibrated leak (capillary tube) By measuring gyro precession forced by vertical acceleration By using an evacuated aneroid capsule connected to the pitot line

Correct Answer:

By measuring the rate of change of static pressure via a calibrated leak (capillary tube)

Question 5

If the pitot tube RAM air inlet is blocked by ice but the drain hole remains open, what will the Airspeed Indicator (ASI) read during level flight?

It will overread significantly as speed increases It will drop to zero It will freeze at the speed held prior to the blockage It will act like an altimeter, climbing when speed decreases

Correct Answer:

It will drop to zero
