Approach Naming, Part One

The topic of approach naming has a few different facets to it. First off, the name of the approach on the approach plate gives an idea of what NAV gear is required for the approach. For example, to fly an "ILS/DME RWY 09" requires DME. Without a serviceable DME on board, the pilot is not permitted to fly that approach. DME distances may be marked on a chart, but if the approach were to be named "ILS RWY 09", then there is no requirement for DME, and the DME distances marked may be used for reference in lieu of other means (crossing bearings of neighbouring NDBs and such).

Part two coming up in tomorrow's post.
