Revision - Pressure Instruments

What is the pitted static system used for in aircraft?

• Communicating with air traffic control

• Navigating the aircraft using GPS

• Controlling the aircraft's landing gear

• Measuring air pressure to power flight instruments

Which instruments rely on air pressure for their readings?

• Attitude indicator, heading indicator, and turn coordinator

• Airspeed indicator, altimeter, and vertical speed indicator

• Fuel gauge and oil pressure indicator

• GPS and autopilot systems

What principle do the attitude indicator, heading indicator, and turn coordinator work on?

• Solar power

• Electrical resistance

• Magnetic fields

• Gyroscopic principles

What does static pressure depend on?

• The altitude

• The speed of the aircraft

• The weight of the aircraft

• The temperature inside the cockpit

What is the approximate static pressure at sea level under standard conditions?

• 29.92 inches of mercury

• 15 inches of mercury

• 24 inches of mercury

• 32 inches of mercury

What does dynamic pressure depend on?

• The size of the aircraft

• The color of the aircraft

• The altitude of the aircraft

• The speed at which the aircraft is moving and the air density

What is total pressure also known as?

• Static pressure

• Pitted pressure

• Dynamic pressure

• Atmospheric pressure

What does the pitted tube measure?

• Total pressure

• Temperature of the air

• Only static pressure

• Only dynamic pressure

What is the purpose of the pitted tube's heating system?

• To measure temperature

• To prevent icing that can block the tube

• To increase airspeed

• To measure humidity

What happens if the static port gets blocked?

• The aircraft will increase in altitude

• The aircraft's engines will shut down

• An alternate static source can be activated

• The aircraft will decrease in altitude
