NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATON ADMINISTRATION: IN CONJUNCTION WITH THE FLIGHT INFORMATION ADVISORY COMMITTEE, AND IN COORDINATION WITH JEPPESEN SANDERSON, INC., ARRIVE AT A STANDARD DEPICTION OF REFERENCE CIRCLES OR DISTANCE RINGS ON INSTRUMENT APPROACH CHARTS. THE DEPICTIONS SHOULD INCLUDE COMMON RADII OR THE NOTATION OF THE RADII ON THE APPROACH CHART AND COMMON CENTERING POINTS FOR THE CIRCLES.
In plain language (FlightFinder summary)
The NTSB asks the FAA, working with the Flight Information Advisory Committee and Jeppesen Sanderson, Inc., to standardize how reference circles or distance rings are shown on instrument approach charts. This includes using common radii (or noting the radii on the chart) and common centering points for the circles.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
