Climbing & Decsending

Question 1

For a steady climb, the thrust must be efficient to overcome

Answer 1

• Drag
• Help lift the weight of the airplane at a vertical speed (rate of climb)

Question 2

In a climb, the lift force is greater / less than weight?

Answer 2

Less!

Question 3

In a climb, thrust is greter /less then drag?

Answer 3

Greater! and this help compensate for the reduced lift force

Question 4

The higher the weight the ___ climb performance

Answer 4

The less climb performance

Question 5

Angle of climb different name

Answer 5

Climb gradient

Question 6

Angle of climb depends on

Answer 6

The excess thrust

Question 7

Maximum gradient (angle) climb

Answer 7

Best used to clear obstacles, gains the greatest height in the shortest horizontal distance

Question 8

Vx

Answer 8

maximum gradient speed. use to clear obstacles fast.

Question 9

Vy

Answer 9

Maximum rate climb speed. Used to reach high altitude as quciky as possible, gains the most height in the shortest time.

Question 10

Maximum rate climb

Answer 10

Gains the most height in the shortest time

Question 11

When weight is increased, the climb performance is

Answer 11

decreased

Question 12

When temparatue increases, the air density?

Answer 12

Lowers

Question 13

When temprate increases the climb perforamnce is

Answer 13

decreased

Question 14

When altitude increases (so does the air density lowers) the climb perforamnce is

Answer 14

decreased

Question 15

Ceiling

Answer 15

The altitude at which steady climb perforamnce falls close to zero

Question 16

Service ceiling

Answer 16

When the rate of climb of a steady climb has fallen to 100ft /min

Question 17

Absolute ceiling

Answer 17

When the rate of climb is 0

Question 18

Headwind / tailwind effect on climb OVER THE GROUND

Answer 18

Headwind will increase climb. Tailwind will decrease

Question 19

Does wind affect rate of climb not over the ground?

Answer 19

no

Question 20

Overshoot effect (during windshear) (an increase of headwing component)

Answer 20

The climb perforamce will increase

Question 21

Conditions for overshoot effect

Answer 21

Flying into an increasing headwind
A decreasing tailwind
Into an updraft

Question 22

Conditions for undershoot (climb perforemce decreased)

Answer 22

A decreasing headwind
An increasing tailwind
Into a downdraft

Question 23

The four forces in STEADY STRAIGHT CLIMB:
1. Lift equals weight and thrust equals drag
2. Lift equals weight and thrust is greater than drag
3. Thrust is greater than drag and lift is greater than weight
4. Thrust is greater than drag and lift is less than weight

Answer 23

4

Question 24

The angle of climb depends upon:
1. Excess lift and weight
2. Excess thrust and weight
3. Excess thrust and minimum drag

Answer 24

3

Question 25

What is Vx?
1. The maximum gradient of climb, giving the greatest height in the shortest time
2. The maximum gradient of climb, giving the greatest in the shortest horizontal distance

Answer 25

2

Question 26

When Vx is used, what shoudl the pilot take into account

Answer 26

High power settings means poor engine cooling

Question 27

In a glide with no thrust, which force is balancing the drag?

Answer 27

Weight. (see page 143)

Question 28

During a glide, if L/D is high

Answer 28

Shallow glide path. Will gllide a long way

Question 29

During a glide, if L/D is low

Answer 29

Steeper glide path, will glide a short way

Question 30

Flying too slow / too fast during a glide will

Answer 30

Make you glide a shorter way

Question 31

Best L/D ratio glide is done by

Answer 31

maintaing the airspeed given by the designer (therefore, speed affects angle of attack)

Question 32

Flaps will (glide)

Answer 32

steepen the glide

Question 33

How does lower weight affect glide

Answer 33

The glide angle will be the same, the glide airpseed will be less
Glide angle will be the same for all weights!!

Question 34

Glide with tailwind / headwind

Answer 34

With headwind, shorther distance is covered,
With tailwind, greater distance can be glided

Question 35

If the L/D ratio is 5:1, and you’re 1nm above (6000 ft) how much ground distance will you glide?

Answer 35

5 nm

Question 36

6000ft (1nm) above ground, L/D is 9:1. How much distance will be glide

Answer 36

9nm

Question 37

The forces acting on a glide are

Answer 37

Lift, weight, and drag.
Take note of the weight traingle assisting in maintaing the glide

Question 38

Headwind / tailwind of a glide will affect the distance over the ground. How it will affect the distance over the air mass

Answer 38

Nothing

Question 39

In a steady glide, drag is balanced by

Answer 39

a component of weight
