Difference betweem a CRP-1 and E6B Flight computer ?

[mrbungle]

Newbie question, save the flaming !!

What's the difference betweem a CRP-1 and E6B Flight computer ?

Is it just Pooleys and Jeppesens variant ?

I'm looking to buy a flight computer, (trying to get som material and equipement together before starting PPL-> )

Thanks.

Main difference, apart from the price (E6B is about 15 quid cheaper), is that the E6B is designed for the US market and therefore has no conversion utility for imperial to metric. Not so handy if you need to convert fuel from gallons to litres for example.

[tyro]

Well I don't know about the mechanical E6B, but the E6B application on my Palm does metric and Imperial conversion for all units, including litres and both types of gallon.

I can imagine that being very handy if I ever wanted to top up a Seneca with litres.

My E6B (bought in Canada) is aluminium body. Have never touched a CRP1 to be able to comment.

Flight Computers

Have had a CRP-1 for 100 years. Perfectly OK computer. It's what you need to pass all the UK exams, compatible with Trevor Thom's books and IMHO it's the one almost all UK FIs are familiar with and you won't go wrong.

According to Transair a CRP1 is £43.50 and an aluminium E6B £30.00. There is a cardboard E6b for 1/2 price but the treatment my stuff got I wouldn't recommend it as an economical purchase.

NOW I use the E6B feature on my Palm Pilot, for which the software cost me about £20.00 from the "Handspring" web-site. Nearly bought a Jeppeson Flitestar or similar once but at £70.00 min. I am glad I got the Handspring and it's bits for far less.

(Incidentally there is also weight and balance software, checklists and masses of other stuff for avaiation available for Handsprings).

Advice - get a CRP1 and get your license. As a treat for passing get a Palm Pilot and kit it out with E6B Software. Don't get it until after the examiner says YES or you'll never learn to use the CRP1.

Nice one.

[Mr Wolfie]

Mr Bungle - to save a few quid you can pick up 2nd hand CRP-1 's on ebay.co.uk for about £20 to £25.

For any real tight-@rses (as long have they have got an IPAQ or other Pocket PC) you can get an electronic E6B for free/gratis/nowt from http://www.navbox.nl/navboxce.htm

[RichyRich]

If they're that tight, Mr Wolfie, surely they wouldn't have a toy like an iPaq?

[Mr Wolfie]

Richy Rich - Good point; well made.

Mr. W

[mrbungle]

All,

Thanks for the replies.

MrWolfie: Had intended to buy from e-bay, thanks !!!

I tried to install that Navbox download on my iPaq, and got a message from the main PC to tell me "<null> is not a valid Win32 application."

Anyone got it to work?


{later} - Doh! It's just a "drop it into the iPaq", not an installer. Works just fine then!

[roundwego]

Is the use of a circular "whiz wheel" computer still a requirement for UK PPL? Have electronic computers not taken over?

[Mr Wolfie]

Installing E6B on IPAQ

Keef,

I had the same error when I first tried to install it.

Download the zip file to your desktop PC. Unzip it. (If you simply click on the program icon it tries to install the program on your Ipaq using Active Sync, fails, and then gives the eror you describe).

All you need to do is copy and paste the navbox program icon (& self-executable file) from your desktop PC onto your ipaq. Just click the new icon that you have pasted into the ipaq and the E6B program runs fine. In fact it is really very good, and includes both the "wind side" and the "conversions & calculator side" of the E6B and includes imperial & US gallons for fuel calculations.

The following info if from the "readme file" that also unzips from the downloaded zip file. (It assumes that you have downloaded and unzipped the file onto a floppy rather than your desktop PC)-


"this E6B calculator as a free sample. You may register

INSTALLATION

1 - Select 'My Computer' and open 'Floppy Disk A:'.

'\ProPlan CE\MIPS' (Casio Cassiopeia),
'\ProPlan CE\SH3' (HP Jornada).

4 - Select the subdirectory for your Pocket PC.

5 - Right-click 'ProPlan CE.exe' and select 'Copy'.

6 - Open Microsoft ActiveSync and contact your Pocket PC.

7 - Click the 'Explore' button.

8 - Select 'My Device\Windows\Start Menu'.

9 - Click 'Edit|Paste' from the menu.

Your ProPlan CE is now ready for use.

Hope this helps.

Mr. W

Keef, You're obviously faster at program installing than I am at typing! Pleased you got it work anyway. Not bad is it?

Mr W.

I wait to be corrected but i thought that using a cirular nav computer was still part of the syllabus.

Mr Bungle- not sure what your plans are long term. I bought a CRP1 for my PPL 9 months ago. Now I have began the ATPL writtens I need a CRP5. Therefore if you're planning to go commercial, bite the bullet and get that straight away

Now who wants to buy a crp1..............!

[mrbungle]

Can you give me a price on your CRP-1 ?
Is it worth going straight for a CRP-5, is it easy to use as a starter, I'll be PPL to ATPL eventually.

Thanks.

[silverknapper]

Sorry mate, someone beat you to it!!

I would definitely go for the CRP-5 if you're going to go commercial. It's bigger than the -1 so the wind side is easier to read off. They look identical to the untrained eye. I wish I had!
And shop around on the web for it. Of all the places I looked, Pooleys were most expensive!!! There was a place in Huddersfield on the web who I got it from, £15 cheaper than Pooleys!!

I was under the impression that the CRP1/5 had a different logarithm to the E6B or whatever it's called. At least that's what I heard from one of the approved training organisations explaining why the UK prohibited the use of the American sliderule.

[tyro]

Dexter256,

Were you told who prohibited it in the UK? Transair and other suppliers were still selling it earlier this afternoon. I'm interested as it's my computer of choice.
