How to decide on the approach?

Some airline SOPs dictate that visual approaches are prohibited if an ILS or RNAV approach is available.

Depending on weather, some crews will opt to take a visual approach for smaller regional jets if there’s an operational advantage (save time and fuel).

If you want to do the cookie-cutter policy and always be conservative, then the order of preference is:

  1. ILS
  2. RNAV
  3. Visual
  4. VOR
  5. NDB

My personal preference for private flying where I care more about saving air time and reducing fuel consumption is:

  1. Visual
  2. ILS
  3. RNAV
  4. VOR
  5. NDB
