    Another rhumb line puzzle
    From: UNK
    Date: 2011 Jun 05, 07:34 +0000
    I want to fly from New York, 40°38′23″N 73°46′44″W to Vienna. 48°06’39” N, 16°34’15” E. My autopilot is linked to a magnetic compass. Immediately after takeoff, I want to set the autopilot to the appropriate magnetic course and then not touch it again until I arrive. What is that course? (There be no wind through the entire flight.)
