Pressure Altimeter

What does an altimeter measure in an aircraft?

• Distance traveled

• Groundspeed

• Altitude above sea level

• Vertical Distance of the Aircraft above a reference datum

Which atmospheric pressure setting is standard on the altimeter for flying at or above the transition altitude?

• 29.92 in Hg

• 30.12 in Hg

• 31.00 in Hg

• 28.92 in Hg

How does the altimeter respond when flying from an area of high pressure to an area of low pressure without adjusting the setting?

• It will read lower than the actual altitude

• It will read higher than the actual altitude

• It will remain unaffected

• It will only change when recalibrated

Which setting on the altimeter provides an aircraft’s true altitude above sea level in standard conditions?

• QNH

• QFE

• QNE

• QFF

If an aircraft descends and the external air pressure increases, how does the altimeter needle respond?

• It rotates clockwise, indicating a higher altitude

• It rotates counterclockwise, indicating a lower altitude

• It remains the same

• It moves in the opposite direction of the increase in pressure

If a pilot sets the altimeter to QFE, what altitude will it indicate?

• Altitude above mean sea level

• Altitude above ground level

• Pressure altitude

• True altitude

When is it essential to set the altimeter to standard pressure (29.92 in Hg or 1013 hPa)?

• When climbing above transition altitude

• When descending for landing

• When taxiing on the ground

• At the end of a flight

When descending into a region of significantly warmer air without adjusting the altimeter setting, how will this impact the indicated altitude?

• The indicated altitude will be lower than the true altitude

• The indicated altitude will be higher than the true altitude

• No effect on altitude indication

• The altimeter will stop functioning

If the static port is blocked during flight, what will the altimeter indicate?

• It will freeze at the altitude where the blockage occurred

• It will gradually decrease as altitude decreases

• It will overestimate altitude

• It will reset to sea level

How does an aneroid barometer within the altimeter work to display altitude?

• t uses GPS signals to determine altitude

• It expands and contracts based on temperature changes

• It measures air pressure, expanding or contracting based on altitude changes

• It uses radar to measure the distance from the ground
