Airspeed Indicator Quiz

What is the basic principle behind the airspeed indicator?

• Measurement of temperature

• Measurement of total pressure

• Measurement of static pressure

• Measurement of dynamic pressure

What is the unit for airspeed generally displayed as?

• Feet per Second (FPS)

• Miles per Hour (MPH)

• Kilometers per Hour (KPH)

• Nautical Miles per Hour (NM/Hr)

What does CAS stand for in the context of airspeed?

• Calculated Airspeed

• Controlled Airspeed

• Corrected Airspeed

• Calibrated Airspeed

What is the airspeed corrected for compressibility effects above 180-200 knots and 20,000'?

• Calibrated Airspeed (CAS)

• True Airspeed (TAS)

• Equivalent Airspeed (EAS)

How is True Airspeed (TAS) calculated using the rule of thumb method?

• Add 1 percent to the CAS for each 1,000 feet of altitude

• Add 4 percent to the CAS for each 1,000 feet of altitude

• Add 2 percent to the CAS for each 1,000 feet of altitude

• Add 3 percent to the CAS for each 1,000 feet of altitude

What is groundspeed?

• The speed of the airplane relative to the wind

• The speed of the airplane in the air

• The speed of the airplane relative to the clouds

• The actual speed of the airplane over the ground

What is Mach number in the context of airspeed?

• The ratio of the IAS of the aircraft to the speed of sound in the same atmospheric conditions

• The ratio of the TAS of the aircraft to the speed of sound in the same atmospheric conditions

• The ratio of the CAS of the aircraft to the speed of sound in the same atmospheric conditions

• The ratio of the EAS of the aircraft to the speed of sound in the same atmospheric conditions

• Best rate-of-climb speed

• Maximum speed in level flight with maximum continuous power

• Stalling speed or the minimum steady flight speed at which the airplane is controllable
