SYS 5 PART 1: ATA31

Which of these barometric instruments uses a restrictor to compute its output?

• Machmeter.

• VSI.

• ASI.

In a Air Data Computer (ADC) system, Mach information is derived from.

• pitot and static pressures.

• indicated airspeed and altitude.

• indicated air speed and total air temperature.

In a Air Data Computer, altitude is produced from.

• static air pressure.

• pitot air pressure and total air temperature.

• pitot air pressure.

In a Air Data Computer (ADC), Indicated Air Speed (IAS) is produced from.

• static pressure only.

• pitot pressure only.

• pitot and static air pressure.

A machmeter works.

• always.

• always except on the ground.

• above 10,000 ft.

In Airways flying, what is the barometric scale of the altimeter set to?

• QFE.

• QNH.

• 1013.25.

The pressure measured at the forward facing orifice of a pitot tube is the:

• static pressure.

• total pressure.

• total pressure plus static pressure

A pitot tube covered by ice which blocks the ram air inlet will affect the following instrument (s):

• altimeter only.

• airspeed indicator only.

• vertical speed indicator only

In a standard atmosphere and at the sea level, the calibrated airspeed (CAS) is:

• higher than the true airspeed (TAS).

• independent of the true airspeed (TAS).

• equal to the true airspeed (TAS).

What corrections must be applied to indicated airspeed to produce true airspeed?

• Correction for heading and altitude.

• Correction for wind and temperature.

• Correction for altitude and temperature.
