I know the differences and it really annoyed me when I found out.
I can't remember which one is which but lets call them the big one and the little one.
The big one is bigger, more expensive and it has a Mach calculation window in it, thats it. It allows you to clacualte Mach numbers given certain conditions.
When I did the CPL exams I did not use this feature and if you know the sum you can work the figure out anyway (38ish * sqrt absolute temp). So having it did me no good.
That said the big one is nicer to use and I wish I had just bought this one. That said I can't remeber the last time I put a wind vector on my VFR plan. It makes very little difference unlessit is blowing a hooley in which case you probably don't go anyway.
A little triv. Do you know what CRP means - Computer Robert Pooley, after the guy who writes Pooleys guide

There's some slightly different calibration on the CRP5 isn't there? Something to do with compressibility ... anyway I remember when I was doing the ATPL flight planning I was trying to use an E6B and kept coming up with an answer that was a few knots out. But when I got hold of a CRP5 it seemed to solve the problem. God knows why one costs more than the other though, they're just little round plastic things, must cost all of about 5 p to make the bastards!!

Hi there,
Anyone else got a Crap5 they've finished with? I need one now and would rather pay another or ex wannabe cash than some flight shop or school, £71.50 is the best I've sen it for, that's rape if you ask me, so if there are any going please do get in touch ASAP.
Regards
