According to the ISA (International Standard Atmosphere) diagram, which parameter remains constant as altitude increases?

• Temperature

• Pressure

• Density

• None of the above

What is the name of the boundary between the troposphere and the stratosphere?

• Tropopause

• Stratopause

• Mesopause

• Thermopause

Which instrument is used to measure the altitude of an aircraft?

• Altimeter

• Airspeed Indicator

• Attitude Indicator

• Turn Coordinator

What component of the altimeter is responsible for measuring static pressure?

• Altimeter Pointer and Scale

• Sealed Case

• Bellows

• Mechanism

What is the function of the sealed case in an altimeter?

• To measure static pressure

• To indicate altitude

• To protect the internal components

• To connect to the static port

Based on the graph shown, what happens to the static pressure as altitude increases?

• It increases

• It remains constant

• It decreases

• It fluctuates

What would happen if the standard atmospheric conditions of the air pressure and temperature outside the static pressure port and the temperature probe were to decrease by 30%?

• The altimeter would show a lower altitude than actual.

• The altimeter would show a higher altitude than actual.

• The altimeter would show the correct altitude.

• The altimeter would not be affected.

According to the image, what does an altimeter setting of 1013 indicate?

• The altimeter is not functioning properly

• The aircraft is at sea level

• The aircraft is at 1000 ft indicated altitude

• The aircraft is at 1000 ft true altitude

What does the altimeter indicate when the aircraft is at Hippe?

• 970 ft indicated altitude

• 1000 ft indicated altitude

• 990 ft indicated altitude

• 1010 ft indicated altitude

What does QNH stand for in the context of altimeter settings?

• The altimeter setting that allows the pilot to avoid terrain and obstacles

• The atmospheric pressure at mean sea level

• The altimeter setting to calibrate for temperature variations

• The code used to communicate with air traffic control
