60-to-1 Rule Practice (Instruments)

Question 1

NM per min formula

Answer 1

TAS/60

Question 2

NM per radial formula

Answer 2

(Distance from NAVAID)/60 nm

Question 3

At 120nm, how many nm are there per radial?

Answer 3

120nm/60rad =2 Nm/rad

Question 4

At 60nm, how many nm are there per radial?

Answer 4

60nm/60rad =1 Nm/rad

Question 5

At 30 nm, how many nm are there per radial?

Answer 5

30nm/60rad =0.5 Nm/rad

Question 6

Radials per nm formula

Answer 6

Radials per nm = 60rad/distance from NAVAID

Question 7

At 120nm, how many radials are there per nm?

Answer 7

60rad/120nm =0.5 rad/Nm

Question 8

At 60nm, how many radials are there per nn?

Answer 8

60rad/60nm =1 rad/Nm

Question 9

At 30 nm, how many radials are there per nm?

Answer 9

60rad/30nm =2 rad/Nm

Question 10

Lead radial formulae

Answer 10

60/distance from NAVAID = radials per nm

OR

Radials per nm x turn distance

Question 11

Descent Rate formula

Answer 11

Rate = nm/min x pitch change x (100ft/nm)

Question 12

Descent rate formula (known gradient)

Answer 12

Rate = nm/min * gradient (in ft/nm)

Question 13

IAS to TAS formula

Answer 13

TAS = FL/2 + 250
- Idk what FL is in this formula

Question 14

Mach to TAS

Answer 14

TAS (nm/min) = Mach # x 10

Question 15

Turn radius (range) formula

Answer 15

TR = (TAS/60) - 2

Question 16

Lead Radial formula

Answer 16

LR = 60/arc DME * turn radius
