Theory Of Flight 2

Question 1

Name the 3 axes on an plane

Answer 1

Longitudinal (roll) , vertical (yaw) , lateral (pitch)

Question 2

What is the type of ailerons that we have on a C-150?

Answer 2

Frise ailerons

Question 3

Is the yaw used to obtain a particular flight attitude?

Answer 3

No

Question 4

What is the load factor?

Answer 4

The ratio of lift of an aircraft and weight

Question 5

What is the load factor for a straight and level flight?

Answer 5

1 or 1g

Question 6

What are the 4 phenomena that cause adverse yaw?

Answer 6

Precession (gyroscopique effect), slip stream, asymmetric thrust and torque

Question 7

What’s cause the yawing movement

Answer 7

On the ground, the left tire is more flattened. Which leads to the aircraft yawing left

Question 8

What’s the asymmetrical thrust?

Answer 8

It’s the yaw must be controlled with each power and attitude change

Question 9

What’s the asymmetrical thrust?

Answer 9

It’s the yaw must be controlled with each power and attitude change

Question 10

What are the two causes of the yawing movement?

Answer 10

Gyroscopic precession and slipstream

Question 11

Depending on the applied power, the slipstream will cause :
A.more yaw
B.less yaw
C. More and less yaw

Answer 11

C

Question 12

What’s the variable pitch for the propellers ?

Answer 12

It’s to control the angle of the propellers

Question 13

What’s the best angle of climb vx

Answer 13

56 knots

Question 14

What’s the best rate of climb Vy?

Answer 14

68 knots

Question 15

What’s the definition of best rate of climb

Answer 15

The greatest gain in height in a given time

Question 16

What’s the definition of best angle of climb

Answer 16

The greatest gain in height in a given distance

Question 17

For the best angle of climb (vx) the wind can effect the climbing angle. If you have some head wind, the angle will be bigger or smaller?

Answer 17

Bigger

Question 18

For the best angle of climb (vx) the wind can effect the climbing angle. If you climb and you have some tail wind, what’s gonna happen with the angle of climb

Answer 18

He will be smaller

Question 19

What’s the speed for a normal climb?

Answer 19

65-75 knots

Question 20

What’s the best glide speed ?

Answer 20

60 knots

Question 21

What’s the circuit speed?

Answer 21

70 knots

Question 22

If you have 10 degrees flaps how much speed do you lost?

Answer 22

5 knots

Question 23

During turns, the lift force has two components, what are they?

Answer 23

1. The vertical component
2. The horizontal component

Question 24

If you have à constant airspeed a larger angle of bank will result in a smaller or a bigger turn radius?

Answer 24

Smaller

Question 25

If you have a constant angle of bank, a slower airspeed will result in a smaller or a bigger turn radius?

Answer 25

Smaller

Question 26

True or false, turn increase the load of factors?

Answer 26

True

Question 27

True or false, the greater the angle of bank, the greater the load factor?

Answer 27

True

Question 28

True or false, in straight level flight, the aircraft has a load factor of 2 (or 2g)

Answer 28

False, it’s a load factor of 1 (or 1g)

Question 29

Answer 29

1600lbs > 97 knots
1450lbs > 93 knots
1300lbs > 88 knots
