What will an Instrument Flight Procedure cost at a public use airport?
For a public use Instrument Flight Procedure, the airport must meet Airport Design Standards. See Appendix 16 of AC 150.5300-13. The cost of an Instrument Flight Procedure will depend on what kind of equipment is there already, and what the airport has to do to meet the Airport Design Standards. These standards include holding position signs and markings, runway marking, obstructions and runway costs to update the airport layout plan, if necessary.
