Climbing

Question 1

Vx and what is it for a jet and a prop

Answer 1

Greatest excess thrust

Vmd for a jet

Vmp for a prop

Question 2

What happens to Vx when you increase temp

Answer 2

For a prop it increases due to increased TAS due to a decrease in density

Same with altitude

Stays the same with a jet for both alt and temp as it is at VMD

Question 3

Vx for a heavy a/c

Answer 3

Faster due to the drag curve moving up and to the right

Question 4

Vx for a dirty config

Answer 4

Will be slower due to the drag curve moving up and to the left

Question 5

Vx with an engine failure on a jet

Answer 5

Slower due to the drag curve moving up and to the left

Question 6

The effect of an engine failure on climb gradient

Answer 6

Reduce it to a quarter

Question 7

Vx with a prop engine failure

Answer 7

Drag curve moves the same way as a jet but Vx gets faster to Vxse

Question 8

Second segment

Answer 8

Engine failure

Question 9

Effect of wind on flight path angle

Answer 9

Increases with a headwind

Decreases with a tailwind

Question 10

Reducing climb angle

Answer 10

Anything which requires acceleration as it requires excess thrust

Turning, the need to increase speed etc

Question 11

Advantages of using best rate of climb

Answer 11

Climb quicker, spend longer in the cruise

Question 12

Roc formula

Answer 12

Roc = angle of climb x speed (TAS)

Roc = Pa - Pr/ W (excess power available)

Roc = g% x TAS

Question 13

G% formula

Answer 13

T-D/w x 100

G% = roc/TAS

Question 14

Vy

Answer 14

Speed for best rate of climb - Max roc

Difference between power required and power available is greatest

Question 15

Service ceiling

Answer 15

Point at which the roc reduces to a specific value

100 fpm for a prop
500 fpm for a jet

Question 16

Absolute ceiling

Answer 16

Height at which the a/c cant climb anymore

Vx is smaller than or equal to Vy

Question 17

Aerodynamic ceiling

Answer 17

Coffin corner

Question 18

Certified ceiling

Answer 18

The ceiling at which the a/c is certified to fly

Question 19

Factors effecting roc

Answer 19

Increasing a/c mass as pr = drag x TAS and induced drag increases

Flaps decrease all vspeeds

Increasing altitude - Tas increases so Pr increases and the curve moves along its own tangent - Vy increases

Question 20

Effect of alt on roc and Vy

Answer 20

Excess power and roc reduce

Vy as a CAS reduce

Vy as a TAS increases

Question 21

Effect on temp with roc and Vy

Answer 21

On hotter days TAS increases so Vy increases

Roc reduces

Question 22

Effect of engine failure on roc and VY

Answer 22

Everything will reduce apart from vx with a prop

Question 23

The effect of wind on roc and Vy

Answer 23

Has no effect

Question 24

Effect of acceleration and turning on roc and Vy

Answer 24

Reduces roc and angle of climb due to the reduced excess thrust

Question 25

Angle and gradient of climb depends on

Answer 25

Excess thrust divided by weight

Question 26

Power formula

Answer 26

F x speed (TAS)
