Flight Instruments

Question 1

What are the different types of airspeed?

PHAK 8-8

Answer 1

1. Indicated airspeed (IAS)
2. Calibrated airspeed (CAS)
3. True airspeed (TAS)
4. Ground speed (GS)

Question 2

What is indicated airspeed ?

Answer 2

The speed you read directly from the airspeed indicator

Question 3

What is calibrated airspeed ?

Answer 3

IAS corrected for installation and instrument error

Question 4

What is true airspeed?

Answer 4

CAS corrected for altitude and non standard temperature

Question 5

What is ground speed?

Answer 5

The actual speed of the airplane over the ground. TAS adjusted for wind

Question 6

What are the different types of altitude?

PHAK 8-6

Answer 6

1. Indicated airspeed
2. True altitude
3. Absolute altitude
4. Pressure altitude
5. Density altitude

Question 7

What is indicated airspeed?

Answer 7

Read directly from the altimeter

Question 8

What is true altitude ?

Answer 8

MSL. Vertical distance of the aircraft above sea level

Question 9

What is absolute altitude ?

Answer 9

AGL

Question 10

What is pressure altitude?

Answer 10

The altitude above the standard datum plane, which is a theoretical plane where air pressure (corrected to 15°C) equals 29.92hg

Question 11

What is density altitude ?

Answer 11

Pressure altitude corrected for variations from standard temperature.
