GROUND SPEED CALCULATION FORMULA
VI. Computing ground speed using TACAN/VOR DME 2.7.5.1.5.1
NOTE: To be able to compute ground speed while maintaining a course
to or from a TACAN/VORTAC station, the DME from station must be
greater than or equal to the aircraft altitude in thousands of feet.
DISTANCE (NM)
______________
X
60 = GROUND SPEED
TIME (MIN)
EXAMPLE: If the altitude is 30,000 ft (FL 300), DME should be 30 nm or
greater.
A.
Start timing with a whole number in DME indicator
B.
After predetermined time (in minutes), check and note DME
C.
Determine distance flown (every 1/10 nm equals 6 kts) and multiply
distance by a number that corresponds to the amount of time
traveled to get ground speed
