A chart includes the radio frequencies used by the ILS components or navaids and the prescribed minimum visibility requirements.Radio-navigation aids must provide a certain accuracy (set by international standards of CAST/ICAO); to ensure this is the case, flight inspection organizations periodically check critical parameters with properly equipped aircraft to calibrate and certify ILS precision."@en }
