What will the new longitude be if an aircraft tracks 090° TT for 315 km from position 60°N, 005°W?
  • A
    000°40’E
  • B
    000°15’E
  • C
    002°10’W
  • D
    005°15’E
315 km = 170 nm = departure = ch.long x cos lat
Ch.long = departure/coslat = 170/cos60 = 340' = 5º40'
Aircraft flies from 005ºW to the East for 5º40' = 000º40'E
