Dead Reckoning Computers
 
Hello All,

Does anyone have pictures of Mk4 or Mk5 dead reckoning computers they would be willing to share? It would help me out a great deal. Happy to PM if required.

With thanks

Excuse me for asking but are CDR's still issued and are students taught how to use the good old Wiz Wheel ?

Sloppy Link 5th February 2013 20:38

Probably can find one you can have, PM me. Still use the whizz wheel for time/distance and fuel calcs.

Come on Herc, it's "ded" as in deduced! Not dead!:eek:

It says dead on the pic of the actual item above :)

yotty 5th February 2013 21:53

Must be right then! ;)

Coffman,

As a Wiz-wheel fan, I'm happy to see it is still being taught on Multi Engine groundschool at Cranwell.

Still taught? I should say so!

Well played Courtney :D:D:D:D

Not much drift at Warp Speed 8 though !

Can anybody explain the differences between the Mk4, 4A, 5, 5A, etc CDRs? Also, which version is current issue for Nav training during EFTS on the Tutor and does anybody out there have one available to purchase or in return for a donation to RAFBF?

All help much appreciated.

Interesting, though, that EVERYONE adopts the same facial expression when using one, Coff.

I've got a "lite" version of this on my watch. Very useful for quick currency conversions and the like. It wasn't a learning curve, more of a learning wall. Once you've climbed the wall, it's easy as pie. If you don't get the thing to begin with, it may as well be in Chinese.

Outstanding photo Courtney, I want to have your babies. :D

Never underestimate the strength of those interstellar winds! :ok:

I hope it was a solar powered one.

No, these 'dead reckoning computers' are no longer issued to EFT studes, nor are they taught how to use one - although there is still an enormous model of one (about 7 ft high!) tucked away in one of the store rooms:)

CoffmanStarter 6th February 2013 16:26

Mach2 ... That's sad ... IMHO the CDR is the most visual/practical way to demonstrate the Triangle of Velocities. So how is Pilot Nav now taught to EFT studes ? :ok:
