Chapter 2 - Pressure

Which of the following statements is correct (P.17)?

• Atmospheric pressure will decrease with a decrease in height

• Atmospheric pressure will decrease with an increase in height

• Atmospheric pressure will stay constant with a change in height

• Atmospheric pressure has nothing to do with height

Which of the following statement is correct regarding pressure and temperature (P.20)?

• cold air will cause pressure to rise rapidly with height

• cold air will cause pressure to fall rapidly with height

• pressure will be higher over cold air

• pressure will be lower over warm air

With the QFE set on the altimeter (P.21):

• the altimeter will read zero feet when the aircraft is on the aerodrome

• the altimeter will read the aerodrome elevation when the aircraft is on the aerodrome

• the aircraft will fly with reference to MSL

• the altimeter will not work properly when the aircraft is flying

To indicate the aerodrome elevation when the aircraft is on the ground, the altimeter must be set with:

• QNE

• QFF

• QNH

• QFE

A line joining places of equal atmospheric pressure is known as:

• isobars

• isogonals

• agonic line

• aclinic line

The standard unit of force is:

• joule

• newton

• pascal

• milibars

Isobars indicate (P.23):

• QNH

• QFE

• QNE

• QFF

Which of the following statement is correct (P.22):

• QNH is calculated using ISA temperature

• QFF is calculated using ISA temperature

• QNH is calculated using actual temperature

• QNH is not calculated with any temperature

Under normal condition:

• if pressure increases, density decreases

• if pressure decreases, temperature decreases

• if pressure decreases, humidity increases

• if pressure decreases, temperature stays constant

The Standard Pressure Setting (SPS) (P.23) is:

• 1013 hPa

• 29.92 mb

• 1013 pascal

• 998mb
