Forgive me if it is covered somewhere:
AFAIK 2D means azimuth guidance only, ie no vertical guidance, only altitude
limits and 3D means the lot, vertical guidance along with the azimuth.
Say, when I do my renewal I only do a RNAV and VOR approach for my non precision stuff....what about an NDB? Whats to stop me conducting an NDB approach if I simply have 2D on my renewal? Or does 2D cover everything...surely not?
