Gen Nav Question Help
Hi Guys (& Girls)
I Need help on the following question:
The Great Circle distance from A at 57'00N 012'30W to B 57'00N 167'30E is
A: 1980nm
B: 6840nm
C: 5882nm
D: 3960nm
I work it out to be 5882nm, but the answer is given as 3960nm????
012'030 + 167'30 = 180'00
180 x 60= 10800
10800 x cos 57 = 5882.10nm
is 5882 the Rumb line distance?
Any help would be much appreciated
Cheers
Danny C
