Depends upon the design of the wing
You have to look at the tables and find out FF/TAS or Mach and get the SFC (specific fuel comsumption) that optimizes the range. Then again you have cost factor engine reserves vs fuel savings. We teach this to our DA-20 crews and they are routinely flying non-stop from Mexican boarder to Canada, saving us a fuel stop. It the P-3 the rule of thumb in dealing with winds before the days of computers and computerized flight plans, was IAS plus 5% of the headwind, and minus 10% of a tail wind.
