Marcum) Distribution: net Organization: Fortune Customer Support Lines: 16 I've been flying for a couple of years (~330 hours now). I learned to use a slipstick during primary training, but do most of my pre- and in-flight calculations with my HP-67, using some programs I wrote. (I never did buy the slipstick!) My programs don't have everything the specialized calculators provide, but I can handle 'course + wind => heading' and density and pressure altitude conversions. The ETA, fuel consumption, distances, etc. I compute using the normal four-functions. I do miss not having a great-circle computation facility, but I just haven't gotten around to building that program yet. And, yes, I carry a spare battery with me when I fly. -- Alan M.
