Question: How should I populate the faaFacilityId attribute in the NavaidEquipment feature when some cases require more than four characters?

Answer: The faaFacilityID is limited to four characters in AC 150/5300-18B.

However, a light system value requires the airport’s three-character identifier and runway designator, resulting in more than four characters. In this case, enter the first four characters in the faaFacilityID field, then enter the full identifier in the name field.
