Lat Long Calculations
Hi
An aircraft departs a point 0400N 17000W and flies 600 nm South, followed by 600 nm East, then 600 nm North, then 600 nm West. What is its final position?
a) 0400N 17000W
b) 0600S 17000W
c) 0400N 16958.1W
d) 0400N 17001.8W
c) marked correct, however I am ending up at (d). Can anyone please check the calculations:
Starting at 0400N 17000W
Flying 600nm South (600/60 = 10 deg) the position becomes 0600S 17000W
Flying 600nm East (600/cos6 = 10.055 deg. 170+10.055 = 180.055. 360-180.05= 179.9449) the position becomes 0600S 179.9449E
Flying 600nm North (600/60 = 10 deg) the position becomes 0400N 179.9449E
Flying 600nm West (600/cos4 = 10.024 deg. 179.9449+10.024 = 189.9689. 360-180.9689= 170.03) the position becomes 04°00'N 170°1.8'W
