GREAT CIRCLE SAILING
CALCULATING DISTANCE:
Ù
Cosine AB = Cosine PA Cosine PB + Sin PA Sin PB Cosine P
CALCULATING INITIAL COURSE:
Ù
Cosine A = Cosine PB - Cosine PA Cosine AB
Sin PA Sin AB
FINDING THE POSITION OF VERTEX:
LATITUDE OF VERTEX:
Ù
Cosine (Latitude) = Sin PA Sin A
LONGITUDE OF VERTEX:
Ù
Tangent (D'long) = Cot A Sec PA …apply the d’long to initial longitude
FINDING THE LATITUDE OF A GIVEN POINT:
Tangent (Latitude) = Cosine (D’long) x Tangent (Lat. of vertex)
-----------o-----------
COMPOSITE GREAT CIRCLE SAILING
CALCULATING DISTANCES
USING NAPIER’S RULE
i) A ® V1
ii) B®V2
Sin (Middle Part) = Product of Cosine of Opposite Parts
Sin (Middle Part) = Product of Tangent of Adjacent Parts
DISTANCE FOR V1 ® V2
(See Parallel Sailing)
-----------o-----------
PARALLEL SAILING
Departure = D’long Cosine ( Latitude )
PLANE SAILING
Sin ( Course ) = Departure
Distance
Cosine ( Course ) = D’lat
Distance
Tangent ( Course ) = Departure
D’lat
RHUMB LINE SAILING
CALCULATING INITIAL COURSE:
Tan ( Course ) = D’long
D.M.P
CALCULATING DISTANCE:
Cos ( Course ) = D’lat
