How could you say that 
Slide rules and Logarithms are wonderful things. They go in my bag of lovely things that includes Integral & differential calculus, Klein & cyclic number groups and my particular favourite the Taniyama-Shimura conjecture; unfortunately Yutaka Taniyama comitted suicide, can't imagine why 
As for CRP thingies I like them because they remind me a bygone days when not everything relied on silicon and Bill Gates. I use my Knightson disk which works fine for my 100kts flying.

Dump them: They hark back to the days of slide rules and logarithm tables I used to struggle though O level maths

Yep. It's easy for shortish trips (when w/v is constant), but the differences in wind "reported" over longer ones make the spreadsheet a bit big. I ended up with a wind velocity column on the sheet, "dittoing down" until I enter a different set of parameters in any given row.
I don't think I'd bother to write it again.

Why not just draw a line on a map, take off, fly your heading, pick a point a few miles away on track, adjust your heading to keep you going towards that point, then do the same again with another point once you've passed it? After your initial calculation with the computer the wind is changing all the time on a long cross-country, so this is effectively what you end up doing anyway, especially if you end up dodging round a shower or something.
As for ground speed, most sane people with their feet in modern reality read that off their GPS, don't they? I do.

I was at school in the fifties with a friend whose Luddite parents wouldn't allow a television in the house.
So poor guy came to school ignorant of all the TV programmes we were all watching.
Just over 100 years ago little boys were sent up chimneys to clean them.
Come on ppruners you all use electronic caculators and you all use the GPS far more than you will sanctimonously admit to on forum.

A friend who was ferrying a Lake in from the USA via the southern route pulled his whizz wheel out in the briefing room in Oporto and attracted a small crowd. Some of the briefers said they'd never seen anyone use one before.

Hi FB
My sorties in the Vintage Massey Ferguson are almost exclusively VFR, towing a triple gang mower to cut the strip grass weekly during the Summer.
I have done one IFR sortie but the grass got so wet the cutters stalled and I had to abandon the sortie.
Wind drift is not usualy a problem but during the Hurricane of 1989 I am relably in formed we harvested half the adjacent Farmers oilseed rape.
But then the idea of a 500HP Volvo diesel tractor with air con , air suspension and Hi-Fi does sound appealing: for a few grand we should get Sat Nav as well.
Nah- not really - its hard to beat the smell of burnt tractor fuel and the sound of skylarks on a late summer evening while the strip flyers circle overhead blipping their engines to get you off the strip for a landing.
Safe flying
