I am currently flying with a Cambridge GPS NAV and a L-Nav. I would like to up
grade or add equipment to help me fly the Turn Area Task. What works well and
what are the important features that can aid in making correct decisions while
flying the Turn Area Task?

A pair of dice, roulette wheel or random number generator would be an
appropriate decision making aid for this task.

Seriously, when you think about it this task is very difficult to
anything rational about. You are going to an unknown point in an
area, the decision as to where to turn depends on a time calculation
with a large error band(the task demands calculations from the pilot
i.e.how long it will take to do the task that the task setter doesn't
want to do) and later in the flight your options close off
particularly if the weather gets better.
Some solutions involve moving the turnpoint on the flight computer
screen, a hazardous activity given this task's opportunity to create
high speed crossing tracks.
A moving map helps only somewhat. Our B2000 handles this moderately
well with a combination of director graphics and simple moving map.
We are working on a new display graphic idea which will help.
