How do I know if a runway has REIL? I'm designing an airport of a flight simulator. One of the runway settings is Runway End Identifier Lights (REIL). Is there a way I can see if a runway at a US airport has REIL via the internet, and whether they are Omnidirectional or Unidirectional REIL?
You can find this information in the Airport Facility Directory which is published in print by the FAA and is available for free from them online here. REIL will be listed for the specific runway for the airport in question. For example I fly out of KDYL and if we take a look at the page in the AFD for KDYL you will see REIL listed for RWY 23
