gives you the following information
Nav equipment and electronic calculators
When permitted, the term 'Nav equipment' includes:
dividers
compass
protractor
ruler (or straight-edge)
non-electronic 'aviation wind triangle and circular slide rule' computer for example Jeppesen Sanderson CR or other brands or a manual slide rule (if the candidate prefers it).
You can only take one manual pilot computer into the exam.
You can use your own calculator if it is part of the permitted material for your exam but it needs to be a ‘basic calculator’.
A ‘basic calculator’ has:
four functions (+, -, x and ÷)
square root function ( √ )
single memory
percentage key (%) is optional.
The calculator must not be programmable or be an 'aviation computer' capable of doing CAS/TAS/MN conversions or solving aviation type problems.
This includes determining ground speeds, required heading, wind components or in-flight winds.
If you are sitting your exam at an Aspeq venue, Aspeq will keep a stock of calculators.
In the event your calculator fails, you can borrow a calculator to finish your exam.
Some comments, if I may -
(a) dividers. I see many students without dividers. Do get yourself a pair. Not all that easy to find, now that the great bulk of drafting work is done via CAD but you can find them if you look around at the art shops and drafting supplies outlets.
(b) protractor. Douglas protractor, not one of the high school half round excuses for a protractor.
(c) computer. Any brand of manual navigation computer. This will be either a Dalton/clone or CR/clone. There are other types still in the marketplace but not in common use. If you are really keen, you can use a scientific slide rule. These work fine but I don't suggest you go down that path. So far as the Dalton/CR is concerned, both are fine for CPL. The Dalton, usually of aluminium, is the more robust, but the CR offers quite a bit more in the way of capability.
The E6B is a Dalton clone. The E6B Circular (marketing gone mad as E6B refers to the original US Army designation for the Dalton) is a CR clone. Easiest way to distinguish the two is
(a) Dalton clone has the fan-shaped grid for wind calculations on a slide which is moved up and down in the main body. ie two separate parts to the whole
(b) CR clone is in one unit. The wind calculation side has square and compass grids.
