From the CPL Licence Application form:
The flight test may be conducted in two parts:
Part 1 – General flying of about one hour;
Part 2 – A simulated charter flight of about 2.5 hours.
Part 2 must include:
- flight planning; completed within 1 hour of advice of the route
(my emphasis)
It's well worth reading this form before you do the test. It provides very specific guidance about what you can be tested on. No VNCs sounds like a load of sh!t to me. Use whatever visual chart you think is best.
