I'm starting to use the Golden Eagle application from FlightPrep, but I noticed something strange. I'll create a route and then click on flight planner and connect to DUATS to get a briefing. Then, when I compare the nav log from DUATS to the nav log created by GE internally, the magnetic courses and winds don't match up.
For example, on the V44 airway from SAM to ABB, DUATS gave a MC of 083 with winds of
351@9 while GE gave a MC of 087 with winds of
010@6. Why? I double-checked to make sure I was using the same altitudes and time and that the current wind information was downloaded to GE. By the way, 083 is the radial listed on the IFR chart for this airway, but why the 087 with GE?
