Question 1

How do you calculate the distance flown at a given speed in a given time?

Answer 1

Set the inner rate (60) to the speed.
Read the distance ( outer ) from the inner ( time )

Question 2

How do you calculate the time given the fuel in the tank and the litres per hour?

Answer 2

Set the inner rate (60) to the litres per hour.
Read the the time from the inner and the litres used from the outer.

Question 3

How do you calculate the climb time and ft per minute?

Answer 3

Inner ring is time ( 80 = 8 minutes )
Outer ring is ft climbed in the period.
Read above the Divisor ( 10 ) on the Inner

Question 4

How do you multiple ( or divide )

Answer 4

Set the divisor ( 10 ) on the INNER circle.
Then read from the inner and outer circles.

Question 5

How do you calculate track error.
Given:
distance covered (say 75 NM )
distance to go ( 30 NM )
distance off ( say 4 NM )

Answer 5

Line up
Outer: Distance OFF (4 NM)
Inner: Distance COVERED (75NM)

Read
Outer ring at the Rate Arrow on Inner

Track error: 3.2 degrees

Question 6

How do you calculate Closing Angle?
Given:
distance covered (say 75 NM )
distance to go ( 30 NM )
distance off ( say 4 NM )

Answer 6

Line up
Outer: Distance OFF (4NM)
Inner: Distance to Go (30 NM)

Read
Outer ring at the Rate Arrow on the Inner

Closing Angle: 8 degrees

Mental Check. As the distance to go is LESS than distance covered - closing angle should be larger.

Question 7

How do you calculate the Total Correction Angle?

Answer 7

Closing Angle + Track Error.
