You need to get it down to about 20 minutes per test. Repeat and repeat and repeat, all subjects.
I am currently doing an FI(R) rating and have been taught a CRP5 method which will save you ages on the wind calcs. Allegedly it is the system that the CRP5 designer had planned.
1. Set up with your wind first - and planned airspeed.
2. Move the slider down to the squares at the bottom. (well down)
3. Change track setting from wind to planned track.
4. Draw a vertical line above and below your cross.
5. Slide slidey bit back up.
6. Align your vertical lines with the nearest drift line on the scale.
7. Read off heading and groundspeed.
I need to scan my whizzwheel to clarify or pm me to go over it over the phone. 100% accurate but easier to demonstrate than type!
