This package contains the database files for fplan. They were created
using the maptools software package from the database files distributed
by the FAA National Flight Data Center, which can be found at:
You should be aware of the fact that the database files from the
National Flight Data Center are not represented as official products
approved for navigation. To be specific, the NFDC world wide web
site clearly states; "FOR RESEARCH PURPOSES ONLY -- NOT CERTIFIED
FOR NAVIGATION". See the fplan user's guide for a discussion of
this and other issues related to database quality.
This database becomes current as of 2015.10.15 and should not be used before
that date, nor after the next version of the database becomes
active, scheduled for eight weeks later.
