2

Question 14

What is static pressure?

Answer 14

Weight after air molecules create a force per unit in all directions

Question 15

What is dynamic pressure

Answer 15

The pressure of the air exerted on a body due to motion

Question 16

What is the dynamic pressure equation

Answer 16

Dynamic pressure=1/2XdensityXspeed^2

Question 17

What does a plane use to take in dynamic pressure

Answer 17

Pitot tubes

Question 18

What does a static port do?

Answer 18

Takes in the static pressure exerted on the plane to calculate the total dynamic pressure for the air speed indicator

Question 19

What is indicated air speed (IAS)

Answer 19

The speed shown on the ASI but can have mechanical problems like instrument and positioning

Question 20

What is calculated air speed (cas)

Answer 20

The same as isa but run through a computer to remove the mechanical problems

Question 21

What is equivalent air speed (esa)

Answer 21

Only used when going slower 0.3 Mach as the air is incompressible

Question 22

What is the true air speed (tas)

Answer 22

Speed reliable to the air it is flying

Question 23

What anagram helps for remembering air speed

Answer 23

ICET is pretty cool drink

Question 24

What is dynamic pressure proportional too

Answer 24

Speed^2

Question 25

How do you calculate ground speed

Answer 25

Ground speed=true air speed+tail wind-head wind

Question 26

What is turbulant air flow

Answer 26

Blocked air flow that is unsmooth

Question 27

What is the point where the air flow gets stopped at the front

Answer 27

Stagnation point

Question 28

When a air flow gets close what happens to the pressure

Answer 28

The dynamic pressure goes up and the static goes down

Question 29

What happens to pressure when an air flow opens back up

Answer 29

Dynamic pressure goes down and static goes up

Question 30

What is bernoullis therom

Answer 30

In a flow of ideal fluid, the sum of static pressure and kenetic energy per unit volume (dynamic pressure) remains constant

Question 31

Where is the area of high static pressure on an object

Answer 31

At the front where the airflow meets it

Question 32

What is an aerofoil

Answer 32

A cross section of a wing

Question 33

What is the front and back of an aerofoil

Answer 33

Leading edge, trailing edge

Question 34

What is the line from the front of an aerofoil to the back called

Answer 34

The chord line

Question 35

What is a camber

Answer 35

A camber is a angled aerofoil to gain lift

Question 36

How does lift and drag work together

Answer 36

Lift goes directly up and the drag pulls it back to create total reaction

Question 37

What happens to the centre of pressure in a symmetrical aerofoil

Answer 37

It doesn’t move

Question 38

What is the lift equation

Answer 38

Lift=1/2XdensityXspeedXsurface areaX coefficient of lift
