Systems section 7

An aircraft flying at Mach .83 would be traveling

• at a faster rate of nautical miles per hour when cruising at a lower altitude of 10,000 ft

• at a faster rate of nautical miles per hour when cruising at the higher altitude of 30,000 ft

• the same rate of nautical miles per hour, regardless of altitude

Which instrument has a pressure reducing needle valve to decrease suction?

• attitude indicator

• altimeter

• heading indicator

• turn and slip indicator

A radio altimeter displays

• absolute altitude

• true altitude

• pressure altitude

• density altitude

On a twin-engine dry-type air pump pressure system, what component can isolate an inoperative air pump?

• double gimbal
• manifold check valve

• pressure regulator

• needle valve

Which instrument is not required for IFR flight?

• heading indicator

• turn coordinator

• vertical speed indicator

• artificial horizon

Which statement is most correct regarding the direct-reading magnetic compass?

• the magnetic compass does not have a diaphragm

• the diaphragm allows fluid to expand or contract with changes in pressure

• the diaphragm allows fluid to expand or contract with changes in temperature

A cylinder head temperature indicator shows the temperature of one cylinder head that is

• most likely to run the coolest in normal operation

• most likely to run the hottest in normal operation

• the farthest away from the instrument panel

Which instrument operates on precession?

• turn coordinator

• vertical speed indicator

• attitude indicator

• heading indicator

What possible issue arises when discharge air from a wet-type air pump is used to inflate rubber deicer boots?

• deterioration of the rubber boots by oil

• the freezing of moisture from the wet-pump system

• unfiltered air supplied to the instruments

The dot in the center of the attitude indicator's symbolic airplane wings represents a pitch change of approximately

• 4 degrees

• 0 degrees

• 2 degrees

• 3 degrees

• 1 degree
