8A Predicting Performance#

Question 1

Performance

Answer 1

The effectiveness of an aircraft in the jobs it was designed to accomplish

Question 2

Performance Charts

Answer 2

Used to predict the performance of an airplane in certain conditions. Located in the performance section of the POH.

Question 3

Interpolation

Answer 3

The process of finding an unknown value between two known values.

Question 4

Density Altitude

Answer 4

Pressure altitude that has been corrected for nonstandard temperature…. more?

Question 5

Headwind Component

Answer 5

Portion of the wind which acts straight down the runway toward the airplane.

Question 6

Crosswind Component

Answer 6

Portion of the wind which acts perpendicular to the runway.

Question 7

Tailwind Component

Answer 7

Portion of the wind which acts directly on the tail of the airplane.

Question 8

Runway Gradient

Answer 8

Amount of change in runway height over its length. Usually expressed as a percentage.

Question 9

Runway Slope

Answer 9

Same as Gradient

Question 10

Braking Effectiveness

Answer 10

How much braking power you can apply without skidding the tires.

Question 11

Hydroplaning

Answer 11

Happens when a thin layer of water separates the tires from the runway.

Question 12

Approach Airspeeds

Answer 12

Airspeed used on approach, specific to flap settings and aircraft weight.

Question 13

Best Angle-of-Climb Airspeed (Vx)

Answer 13

Provides the greatest gain in altitude in the shortest distance during climb after takeoff.

Question 14

Best Rate-of-Climb Airspeed (Vy)

Answer 14

Provides the greatest gain in altitude over a period of time.

Question 15

Cruise Climb Speed

Answer 15

Generally higher than Vx or Vy, and the rate of climb is lower.

Question 16

Absolute Ceiling

Answer 16

Altitude at which the airplane is unable to climb any further.

Question 17

Service Ceiling

Answer 17

Altitude where a single-engine airplane is able to maintain a maximum climb of only 100 feet per minute. (Practical Ceiling)

Question 18

Cruising Speed

Answer 18

Usually chosen to cover the distance in the shortest period of time.

Question 19

Maximum Level Flight Speed

Answer 19

When the force of total drag equals the force of full thrust.

Question 20

Maximum Range Speed

Answer 20

Lets you travel the greatest distance for a given amount of fuel. (mpg economy)

Question 21

Maximum Endurance Speed

Answer 21

The speed and power setting which allows the airplane to remain aloft for the longest possible time.
