Pitot Static System

Question 1

How does the airspeed indicator work?

Answer 1

It measures and compares the impact pressure at the pitot tube, versus the static pressure at the static source

Question 2

What is indicated airspeed?

Answer 2

The airspeed read directly from the airspeed indicator

Question 3

What is calibrated airspeed?

Answer 3

Airspeed corrected for errors of the airspeed indicator and errors caused by the position of the pitot tube and static source

Question 4

When is the difference between indicated and calibrated airspeed greatest? Lowest?

Answer 4

Greatest - Slow speeds and with flaps
Lowest - Cruise speed and altitude

Question 5

Where can a pilot find the calibrated airspeeds?

Answer 5

In the airplane operation manual

Question 6

What is true airspeed?

Answer 6

Calibrated airspeed corrected for temperature and pressure variation

Question 7

Where is the only place the airspeed indicator shows true airspeed?

Answer 7

At sea level

Question 8

What happens to indicated airspeed as altitude increases at the same power settings?

Answer 8

Indicated airspeed decreases

Question 9

What is a general formula for true airspeed compared to indicated airspeed?

Answer 9

2% increase for every 1000’ altitude

Question 10

What is Vs? Where is it shown on the airspeed indicator?

Answer 10

Stalling speed, power off, flaps up, maximum weight / The bottom of the green arc

Question 11

What is Vno? Where is it shown on the airspeed indicator?

Answer 11

Maximum structural cruising speed with flaps up and maximum weight / The top of the green arc

Question 12

What is Vne? Where is it shown on the airspeed indicator?

Answer 12

Never exceed speed / The top of the yellow arc

Question 13

What is Vfe? Where is it shown on the airspeed indicator?

Answer 13

Full flap operating range maximum speed / Top of the white arc

Question 14

What is Vso? Where is it shown on the airspeed indicator?

Answer 14

Power off, full weight, full flaps stall speed / Bottom of the white arc

Question 15

When should the plane be reduced to maneuvering speed?

Answer 15

In rough air or turbulence

Question 16

Where is maneuvering speed found?

Answer 16

In the pilot operating handbook

Question 17

What needs to be set properly for the altimeter to be accurate?

Answer 17

Barometric pressure

Question 18

What is indicated altitude? How is it abbreviated?

Answer 18

Altitude read from the altimeter when it is set to the current pressure setting / MSL or Mean Sea Level

Question 19

What is pressure altitude?

Answer 19

It is read when the pressure is set to 29.92”

Question 20

What is density altitude?

Answer 20

Pressure altitude corrected for non-standard temperature

Question 21

When are true, pressure, and density altitudes all the same?

Answer 21

At standard pressure and temperature

Question 22

What is the relationship between density altitude and pressure altitude with temperature?

Answer 22

Warmer than standard temperature, density altitude will be higher than pressure altitude.
Colder than standard temperature, density altitude will be lower than pressure altitude.

Question 23

What is absolute altitude?

Answer 23

Actual physical feet above terrain

Question 24

What is true altitude?

Answer 24

True vertical distance above sea level

Question 25

What altitudes are shown on aeronautical charts?

Answer 25

True altitude

Question 26

When is alternate static air used?

Answer 26

When the primary static air source is blocked
