Hate to add another complication, but the LDA is not shown on Jeppesen 10-9 charts. In the U.S., the LDA may be shorter than the runway length beyond the threshold if part of that runway length must be used to satisfy runway safety area, object free area, or runway protection zone requirements. See paragraph 4-3-6 of the AIM (
http://www.faa.gov/air_traffic/publi...aim0403.html.6). At present, the only place declared distances are published in the U.S. is in the Airport/Facility Directory (
