CRP-5

[PeteB]

Just a quick query:

Just started ATPL theory with Bristol, and they recommend the Airtour CRP-5 as a flight computer. However, the only CRP-5 I can find is made by Pooleys. Are they the same? Obviously I don't want to be learning how to use the airtour version, then trying to work out how the Pooleys version does the same calculation. Can someone out there doing the same course enlighten me? (AND - £60+ for a flight computer? blimey...)

Airtour old name trading name for what is now
Pooleys. Unless someone knows better.

Your current CRP-5 should be fine.
Best of luck with course.

All becomes clear....! Thanks very much!

What does CRP stand for?

I know that it is off topic (sorry Mr Scroggs), but I have always wondered what the "CRP" stood for?

When I was studying, it was always refered to as CR*P 5, which seemed most apppropriate

PeteB,

They all do the same sort of thing .. so, unless the one you have in hand doesn't have a few add-on functions which are necessary for your examination training ..... why bother changing ?

The main decision is whether you want a pocket fitting Jeppesen or not ....

CRP stands for...

Computer Rob(ert) Pooley!

That is, the chap who started/runs the company. Sounds over-simple but I know it is definitely true because his wife told me,

CRP stands for ...

Thanks for the reply Token Bird. Yes that does seem a very likely explanation, as I am well aware of Robert Pooley & all the good work that he has done for General Aviation.

I should add, that I was in no way implying that the CRP 5 was cr*p, only that I was total cr*p, in learning how to use it!

CRP5 is a nightmare.
I'd suggest you take a look at the CD-ROM interactive tutor on it, also made by Poolys (does both the CRP 5 and CRP 9).
It's blinding!!!!!!!!!!!!!!!!!!!!!.

I'll stick with a small 3 3/4" Jeppesen circular CR type. In some problems I find them easier to use and the pocketable convenience factor is worth its weight in ....er....something...

In the RAF they're known as Dalton Computers - perhaps someone can tell us why? I still have my 'Computer Dead Reckoning Mk. 5A' and carry it with me on every trip. You never know when the GPS/IRSs may choose to screw up!

Because the original model was invented by an American called Fred Dalton.

The CRP-5 is not difficult. If you are taught in class or by your instructor to use it (as opposed to self-taught) you should be shown the reminders that are on the computer itself. In fact taking the thing in to an exam should be regarded as cheating - it effectively tells you how to make each calculation, if you have been shown what to look at!

The CRP-5 is a very fine computer, better than my RN-issue Daltons or my Jeppeson (though that, being aluminium is very robust). It is also the one the JAA use to work out the answers, and since some are very close together by the CAA's admission, should be the one all ATPL students use.
