Jeppesen CR-3 or ASA E6B

[danny_galaga]

I only got up to my first nav about 25 years ago, so now it's time to get back into it. First time around I had (still have) a Jeppesen CR-5. It looks bloody minute now! About to order some stuff. I recall seeing the ASA type computer, and thought they looked interesting, but my flying school at the time used Jeppesen. What are people's thought's on the pros and cons? One pro for Jeppesen is compactness of course, although the CR-3 is 6" . I think there used to be a CR-4, but even in the 90's it was discontinued. 

 

Also, what other bits and pieces will I need for studying? I'm ordering some new WAC and VNC. I still have an ASA ATC-RP1 ATC navigation plotter. Will also get a Flightrule navigation protractor.

Which exam?

E6B for PPL/CPL exams

CR3 for ATPL exams

 

Google "casa <your exam> permitted material", and bring everything permitted. eg.

Does ra aus navigation exam come under ppl?

You can use both for all calculations.

 

If using E6B for high speeds in the range 220kt - 700kt, you'll need to buy additional high speed slide.

I'm flying rag and tube bushplane so I suspect I won't need that extra bit 😄

 

I'll probably go with the Jeppesen then. Thanks for the info 🙂

While you need this for your RAAus cross country (or a RPL Nav) will you use it after you have the endorsement ?

 

Most likely you will only use a EFB as most (with an internet connection) can get the winds and if you setup your plane profile correctly will also give you likely fuel consumption.

Plus an iPad with a GPS can also give you updated times to next waypoint etc.

 

I have an ASA E6-B which I used to calculate heading/speed. For everything else I used the calculator on my phone.

One in 60 rule is pretty handy. Reciprocals add 200, Minus 20 or deduct 200 Plus 20. Nev
