I agree with BPF on diversion PPL vs real world.
If diverting per examiner, he wants to see some mental work in use.
Simple diversion is, when the examiner requests a diversion to X, draw a circle where you ARE and a circle where he said GO, DRAW a line between the two.
Look at the compass rose around a VOR etc and estimate the heading to your destination based on how the line you drew would overlay the compass rose.
eg. take a pencil and place along diversion line, hold pencil at same angle and move to nearest VOR and read heading.
Now use Lat/Lon lines 20-21 NM east/west, 30nm north/south on a VNC VFR 1:500000 to estimate distance. If 180kts GS, then 3miles/min.
Now the most important part...with a/c STABLE set HDI to agree with Mag compass, record time. Then start diversion. Tell examiner the ETA to first chk pt.
