The primary goal of Volume II is to standardize how States, operators, and charting organizations design flight procedures. This uniformity ensures that a pilot flying into any international aerodrome can rely on consistent safety margins, regardless of local terrain. Key areas of focus include: including wind spirals and bank angles
: Protecting the transition from instrument flight to visual landing. Latest Updates
