Appologies to Gary and all Navlist members my previous reply was too terse and further should have been directed to Bill B.
Google Earth claims1 degree longitude at 41 N represents .76 degree arc. This is correct.
GE also says the arc is 45.46 nm long. therefore 45.46nm / 60 nm/degree = .7576 degrees.
