REFLECTOR: First long Cross Country

[Richard J. Gentil]

Scott,

Thank you for the info. From high altitude what descent rate do you plan for?  You use the standard 500ft/min or do you use less and go with the higher TAS over a greater distance?

I'm not convinced I save any gas by flying higher than 12500 or 13500.  Unless there is a wicked tail wind in the upper teens that you can catch a ride on. It takes a much longer climb to 18,000 ft and its going to take quite a few miles at the reduced fuel burn you'll get at the higher altitude to make up for that.
