Nav ex.
Somewhere in the triangle you will have a diversion,this will happen when you are flying one of the legs,you will need to plot and fly the new route and manage the aircraft correctly.
You will be asked to find a waypoint such as an old airfield,lake or similar.
Anyway that's what happened to me.
Then after nav in the skills test you will be asked to demonstrate correct handling of the aircraft in all the situations that you have previously learned.total time around 3 hours,good luck.
