1
Q

What is mass?

A

Quantity of matter in a body ( not related to gravity)

2
Q

What is weight?

A

Heaviness if matter (related to local gravity)

3
Q

Speed is relative. True or False?

A

True

4
Q

What is lift?

A

The force generated by the flow of air over the wings of an aircraft. It is also generated by the tailplane

5
Q

Is the pressure above the wing high or low?

A

Low

6
Q

What is gravity?

A

The downward force acting on all bodies vertically down towards the centre of the earth

7
Q

Where does the weight act through?

A

The centre of Gravity (CoG)

8
Q

What is thrust?

A

The force which gives aircraft forward movement

9
Q

Thrust acts through the

A

Thrust line

10
Q

Where does lift act through?

A

The centre of pressure

11
Q

Can the CoG move position?

If so how does it move, provide an example.

A

Yes.
Fuel in tanks
Position of load.

12
Q

Where does drag act through?

A

The drag line, opposes thrust.

13
Q

When is an aircraft considered stable?

A

When the aircraft will tend to go back to level flight of its own accord without pilot interference

14
Q

Pressure on top of the wing is?

A

Less than the bottom

15
Q

What does Bernoulli’s principle state?

A

Rise/fall in Pressure within a flowing fluid must always be accompanied by a decrease/increase in speed.

16
Q

The slower the air the higher the pressure. True or False?

A

True.
