# 8.3 - Theory of Flight Flashcards

1
Q

A

Load factor = Total lift / Aircraft weight

2
Q

Identify

A
3
Q

Which type of flap will create the most amount of drag?

A

Split flap

Notice that the split flap doesnt change the upper camber of the wing, having little effect on lift produced.

It does however impede into the bottom side of the wing trailing edge adding very large amount of drag

Q

Flaps are also known as

A

High lift devices

7
Q

What is the formula for glide ratio?

A

Glide ratio = Horizontal distance covered / Sink distance

8
Q

What is the main advantage of a slat?

A

It delays the stall allowing you to fly at a high angle of attack

9
Q

What effect would increasing the static stability have on dynamic stability and control?

A
• increases dynamic stability
• decreases control
10
Q

Dutch roll is caused

A

tail wagging which causes the tail to yaw and roll from side to side

11
Q

What does Vs stand for?

A

Stall speed

12
Q

What is meant by TAS

A

True airspeed which is airspeed corrected for density

13
Q

What is the density at sea level ISA?

A

1.225 kg/m3

14
Q

Does the stall angle change in a turn?

A

'’The stalling angle is constant at all times (providing the wing geometery does not change).

15
Q

What is the difference between the Vx and Vy climb?

A
16
Q

What is the equation for the Re (Reynolds number)?

A

Re = inertia forces / viscous forces
