What does an airport depicted in Blue on an Enroute Chart indicate?

• A. Instrument Approach and/or Radar Minima published in at least DOD HIGH ALT FLIPs, possibly LOW ALT DOD FLIPs, or any FAA pub
• B. Instrument Approach and/or Radar Minima published only in FAA Terminal Procedures
• C. No Instrument Approach or Radar Minima Published anywhere
• D. Only VFR minima published

Answer: (A)

Blue on an Enroute Chart shows that instrument approach and/or radar minima are published for that airport in official publications. This color cue tells you there are published IFR procedures you can use, and you should look up the exact minimums in sources such as DoD High Altitude FLIPs (and possibly Low Altitude FLIPs) or FAA publications. It’s a quick way to know that IFR procedures exist at that field and where to find the published minimums. If an airport isn’t blue, it doesn’t necessarily have published instrument approaches in those sources, so IFR planning would rely on VFR or other specific publications.
