Hi,
I have been looking at the epst compass test - (
www.epst.com/com/compas.html) and I am still unsure how you work out whether the correct answer is 1 or 3. I wonder if someone could clarify how you use the RBI to distinguish whether 1 or 3 is the correct answer (I obviously realise it is 1 or 3 as the plane is heading west a descending)
Thanks.
