Flight Performance and Palnning

Question 1

consequences of an over loaded aircraft?

Answer 1

Take-Off and landing speeds Increased
Take-off landing distances Increased
Climb performance Degraded
Cruise Speed Reduce
Range Reduced
Service ceiling Reduced

Question 2

Max total weight authorised?

Answer 2

Maximum weight for take-off, also know as Max all up weight and Max take-off weight.

Question 3

Max Ramp weight?

Answer 3

Max weight of parked aircraft

Question 4

Max Zero Fuel weight?

Answer 4

Max weight allowed with zero fuel in the tanks.

Question 5

Gross Weight?

Answer 5

The actual of the loaded aircraft is referred to as the gross weight.

Question 6

Lever arm?

Answer 6

The distance from the datum to the location of each item of loading is the lever arm.

Question 7

Equation for centre of gravity?

Answer 7

total moment / total weight (mass) = Centre of Gravity

Question 8

effect of using more flap then recommended?

Answer 8

Lengthen take-off distance, because of increased drag.

Question 9

Effects of using the recommended take-off flap setting?

Answer 9

will shorten the take-off ground run, however climb performance may be degraded.

Question 10

effects of not using flap on take off?

Answer 10

Greater take-off distance, climb may be quicker.

Answer 12

10 Factor 1.1

Question 13

Percentage increase in take-off distance: 10oC increase in temp?

Answer 13

10 Factor 1.1

Question 14

Answer 15

30 Factor 1.3

Question 16

Percentage increase in take-off distance: Runway upslope of 2%

Answer 16

10 Factor 1.1

Question 17

Percentage increase in take-off distance: Tailwind component of 10% of lift-off speed?

Answer 17

20 factor 1.2

Question 18

Percentage increase in take-off distance: Soft ground or snow?

Answer 18

At least 25% at least 1.25

Question 19

Best range airspeed?

Answer 19

Max range occurs at an angle of attack very close to that at which the wing is also producing minimum drag.

Question 20

Max endurance?

Answer 20

Longest possible time spent airborne, it is achieved at minimum power required airspeed. Slower than the best range airspeed
