Flight Planning and Performance Pt.2

Question 1

This is obtained when the power or thrust required equals the maximum power or thrust available from the powerplant

Answer 1

Maximum level flight airspeed

Question 2

This is not usually defined by thrust or power requirement since conditions of stall or stability and control problems generally predominate

Answer 2

Minimum level flight airspeed

Question 3

This occurs when an aircraft gains potential energy by increasing altitude

Answer 3

Climb Performance

Question 4

What are the two basic factors that contribute to positive climb performance in most aircrafts?

Answer 4

• The aircraft climbs using excess power above that required to maintain level flight
• The aircraft climbs by converting airspeed to altitude

Question 5

This may provide climb performance to ensure an aircraft will clear obstacles

Answer 5

Maximum Angle of Climb (Vx)

Question 6

Provides climb performance to achieve the created altitude gain over time

Answer 6

Maximum Rate of Climb (Vy)

Question 7

True or False. If weight is added to an aircraft, it must fly at a lower AOA to maintain a given altitude and speed.

Answer 7

False. An aircraft must fly at a higher AOA to maintain a given altitude and speed.

Question 8

This is the altitude at which the aircraft is only able to climb at a rate of 100 feet/min

Answer 8

Service ceiling

Question 9

This is the altitude at which the aircraft is unable to climb

Answer 9

Absolute Ceiling

Question 10

This involves consideration of flying distance

Answer 10

Range

Question 11

This involves consideration of flying time

Answer 11

Endurance

Question 12

This occurs when you have the greatest amount of flying time for the least amount of fuel

Answer 12

Maximum Endurance

Question 13

This occurs when you get the greatest distance for a given amount of fuel

Answer 13

Maximum Range

Question 14

Any surface that is not hard and smooth increases the ___________ during takeoff. This is due to the inability of the tires to roll smoothly along the runway

Answer 14

Ground Roll

Question 15

This refers to the amount of power that is applied to the brakes without skidding the tires

Answer 15

Breaking Effectiveness

Question 16

This is the amount of change in runway height over the length of the runway. This is expressed as a percentage

Answer 16

Runway Gradient or Slope

Question 17

This indicates the runway height increases, and a negative gradient indicates the runway decreases in height

Answer 17

Positive Gradient

Question 18

What is the positive gradient computation?

Answer 18

RWY Elevation (Higher end) - RWY Elevation (Lower End) / RWY Length x 100

Question 19

This impedes acceleration and results in a longer ground roll during takeoff. However, landing here typically reduces the landing roll

Answer 19

Upsloping runway

Question 20

This aids in acceleration on takeoff resulting in shorter takeoff distances. But landing here increases landing distance

Answer 20

Downsloping runway

Question 21

This reduces the friction between the tires and the ground and can reduce braking effectiveness. This can cause hydroplaning

Answer 21

Water on the runway

Question 22

This is condition in which the aircraft tires ride on a thin sheet of water rather than on the runway’s surface

Answer 22

Hydroplaning

Question 23

What is the formula for. the minimum hydroplaning speed?

Answer 23

9 x √tire pressure (in psi)

Question 24

What are the effects of increased weight on takeoff?

Answer 24

• Higher lift-off speed
• greater mass to accelerate
• Increased drag and ground friction

Question 25

What are the effects of increased weight on landing?

Answer 25

• Higher approach speed
• More runway used to decelerate
• Wear and tear on brakes

Question 26

What are the five takeoff and landing performance factors?

Answer 26

• Weight
• Wind
• Rotation Speed
• Landing Speed
• Density Altitude

Question 27

Effects of headwind during takeoff?

Answer 27

• Lower groundspeed needed to reach rotation speed
• Shorter ground roll

Question 28

Effects of tailwind during takeoff?

Answer 28

• Higher groundspeed needed to reach rotation speed
• Longer ground roll

Question 29

Effects of headwind during landing?

Answer 29

• Less ground roll
• Ground speed is lower at touchdown

Question 30

Effects of tailwind during landing?

Answer 30

• Increased landing roll
• Ground speed is higher at touchdown

Question 31

Effects of takeoff below rotation speed?

Answer 31

• Aircraft could stall
• Difficult to control
• Low initial rate of climb

Question 32

Effects of takeoff above rotation speed?

Answer 32

• Improved initial rate of climb and “feel” of the aircraft
• Increase in takeoff distance

Question 33

Effects of Landing below specified speed?

Answer 33

• Aircraft may stall
• difficult to control
• Develop high rates of descent

Question 34

Effects of landing above specified speed?

Answer 34

• Improves controllability slightly (especially in crosswinds)
• Increase in landing distance

Question 35

Effects of an increase in density altitude on takeoff?

Answer 35

• Greater takeoff speed
• Decreased thrust and reduced accelerating force

Question 36

Effects of an increase in density altitude on landing?

Answer 36

Increased landing speed but does not alter retarding force

Question 37

This means taking known information and compute intermediate information

Answer 37

Interpolation
