Bob, I have been a private pilot since 1977 and for the longest time... way too long, I fought with the infamous WhizWheel as we all know it, but last year, I invested and I mean invested $69, did I say INVESTED... in a Sporty's E6B electronic flight computer. It has made life just so, so much easier and QUICKER. There are so many useful functions and it displays three time configurations, so you never have to figure out what Zulu time is again, it is always available on the Sporty's E6B. It is so small, it can mount on the yoke, velcro it to a kneeboard or just wear it in a holster on your waist. I almost never make suggestions to what people should or should not have, but I think every pilot should have an E6B in their flight bag. You can find the Sporty's E6B here. http://www.sportys.com/acb/showdetl.cfm?&DID=19&Product_ID=225&CATID=93
and if that link does not work, just go to http://www.sportys.com
and look for the E6B.
Take care... Happy Landings!
