Answer 2

1.15

Question 3

1nm = __ km

Answer 3

1.85

Question 4

How to convert between sm, nm and km

Answer 4

Using rough conversions numbers as a reference scale, align inner numbers on flight computer with known distance and read other distances also referring to inner scale

Question 5

Answer 5

3.28

Question 6

1ft = __ m

Answer 6

0.305

Question 7

1 lb = __ kg

Answer 8

2.2

Question 9

1 imperial gallon = __ US gallon

Answer 9

1.2

Question 10

1 imperial gallon = __ L

Answer 10

4.5

Question 11

Specific gravity of fuel

Answer 11

0.72

Question 12

Converting volumes of fuel to mass

Answer 12

Determine if its the lb or kg specific gravity scale, align fuel volume on inner scale with the unit, the mass of fuel will be on the inner scale aligned with 0.72 on the specific gravity

Question 13

1 impG = __ kg of fuel

Answer 13

3.3

Question 14

1nm = ____ ft

Answer 14

6076

Question 15

1sm = ____ ft

Answer 15

5280

Question 16

1sm = ___ nm

Answer 16

0.87

Question 17

1sm = ___ km

Answer 17

1.61

Question 18

1km = ___ sm

Answer 18

0.62

Question 19

1km = ___ nm

Answer 19

0.54

Question 20

Distance, speed, velocity calculation

Answer 20

• 60 on inner aligns with time in mins on outer

- distance on outer (nm) will align with speed on inner (kts)

Question 21

Fuel consumption rate calculation

Answer 21

• Fuel consumption is L/hr so 60 on inner aligns with consumption rate on outer, it is also referred to as the burn rate
• time (mins) on inner aligns with the quantity of fuel on outer (L)

Question 22

Fuel maximum endurance

Answer 22

Remaining airborne as long as possible using all the fuel on board

Question 23

Fuel safe endurance

Answer 23

Maximum flight time achievable without burning the legal reserve requirement of 30 mins during the day or 45 mins at night

Question 24

Division

Answer 24

first number/second number = answer/1

so align first number on outer scale with second number on inner scale and answer will be on outer scale aligned with 10 (1) on inner scale

Question 25

Multiplication

Answer 25

Align first number on outer scale with 10 on inner scale, and then second number on inner scale will align with answer on outer scale

Question 26

TAS calculation

Answer 26

• align the temp with pressure alt in the middle window and then CAS on inner scale will align with TAS on outer scale

Question 27

Proportions

Answer 27

Align first proportion against each other (e.g time on inner and distance on outer) and then resultant proportional will be aligned so you can find answer by seeing what the other known value aligns with

Question 28

ROC/ROD

Answer 28

It is the vertical distance in ft per min

• 10 on inner scale aligns with ROD/ROC on outer scale
• time of climb/descent in mins on inner scale aligns with vertical height distance in ft on outer scale
