Thank you Pete. Not to late at all. By company policy I have to get three estimates.It is interesting to see different practitioners with different methods cluster around the same answer, and the small variation. Eddie: 1.12kts @ 143.6d Pete: 1.2 kts @ 141d Bill: 1.1 kts @ 140.7d (yes, this is my FINAL answer ;-) USCG: 1.2 kts @ 141d Thanks to all Bill > Bill, > > After plotting the scenario out and measuring the distance between what I got > the same answer as the "answer" provided as the "correct answer" > > My Calculations: > > 1020 to 1112 is 52 min > > 52 minutes is 0.86 hour > > 0.86 x 9.2 knots = 7.97 nm > > (agree with your CDMVT conversion) 045d T at 7.97 nm = 41d 15.685' N, 071d > 42.545' W > > The difference between that point and the waypoint is 141d at 1.2 knots. > > Hope I wasn't too late in my response. > Pete >
